What is Broadband?Have
you ever tried an Internet search for "broadband"? We did and got 428
MILLION results. Searching for "Taylor Swift" only got about twice as
many results! There certainly is a lot of talk about broadband. "Broadband" has become synonymous with "high speed
Internet connection," but that's not where the
term originated.
Ever wonder about the origin of "broadband"? If you
look at some of the links you get from the Google search, almost every
link has a different definition according to their viewpoint.In February 1997, twenty-seven years ago this month, the first consumers
were connected to the Internet with what we call "broadband" today.
Up to that point, most users connected to the Internet with "dial-up"
modems on a POTS (plain old telephone service) copper line. Dial-up
connection speeds at the time were mainly 14.4 kilobits per second or 56
kilobits per second. Yes, kilobits per second - thousands of bits per
second. The only alternatives for digital phone connections was T1
service at 1.544 megabits/second and thousands of dollars per
month connection fees. ISDN (Integrated Services Digital Network) over
copper phone wires had been announced but was rarely available and faded
quickly.
The innovation that introduced "broadband" Internet access to the
consumer was the Cable Modem, developed in the Boston, Massachusetts
area by Rouzbeh Yassini at Applitek. Yassini turned Applitek into
LanCity to manufacture the cable modem for CATV companies. The original
Applitek design was a networking system using coax cable and FM
(frequency modulation), a technique then called "broadband". Yassini
realized the commonality of design with CATV systems and developed a
system to put data on spare channels of a CATV system and the cable
modem as created.
The T1 line from the phone company and most other networks like Ethernet
were AM (amplitude modulation) systems commonly called "baseband"
systems. When a broadband network like CATV with cable modems became the
source of high data rate Internet access, broadband became synonymous
with high bandwidth. Today broadband refers to any high bandwidth
network. Fiber broadband is probably redundant since no high bandwidth
network runs without fiber optics.
CATV companies were already using fiber optics to upgrade their
networks to hybrid fiber coax networks using special lasers called DFB lasers also developed in Boston by AT&T. The
combination of the large numbers of subscribers to CATV and the
technologies of HFC networks and cable modems made broadband a reality
to many subscribers very quickly.
The telcos tried to match cable modem speeds over their twisted pair
wires but with little success. The development of digital subscriber
line (DSL) lasted through more than 20 generations of standards and
still has advocates today, although most major telcos have abandoned it
in favor of fiber to the home (FTTH.) DSL was never going to be able to
keep up because of the physics of transmitting electrical signals over
the telco twisted pair wires.
Fiber to the home is considered the ultimate solution to provide
broadband for today and the foreseeable future, but the CATV companies
have not been standing still. From the original cable modem speeds of 4
Mb/s, they have developed new cable modem technology that can now do
gigabit speeds for downloads but are more limited in upload speeds. Most
CATV companies have experimented with and are prepared to move to FTTH
when necessary.
What Others Say About The Development Of The Cable Modem
SCTE Broadband Library
Dr. Rouzbeh Yassini was interviewed by SCTE about the cable modem.
It’s ironic that sometimes cable doesn’t get credit for ushering in the broadband revolution.
I think the cable industry didn’t get credit for three things.
First, we didn’t get credit for bringing broadband to the market — and
we still don’t. We really haven’t marketed the word ‘broadband’ as a
cable innovation. Second, we didn’t get credit for doing this with the
persona of entrepreneurs versus established, giant companies. And
lastly, for making it nearly ubiquitous; for making this technology
available and continuously improved with faster speeds and better
performance. For making the revolution an evolution. We were bad at
marketing and public relations. We were good at delivering services and
solutions and making a lot of innovation happen.
Dr. Yassini in an interview in SCTE Broadband Library.
First Person History
Your editor (JH) became one of the first consumers to get a LanCIty
cable modem at our home in a suburb of Boston. We had an inside track
since Applitek was a customer of our fiber optic company and we chaired
the tech committee for the schools in our town that was also home to a
number of people involved in the development of the technology. The
schools in our town did field trials of the cable modem prototypes using
the CATV connections provided to the school system by our local cable
company Continental Cablevision. The cable modem prototypes were built
into large desktop PC cases. By the time we got our connection at home,
the device had been shrunk to the size of a cable box.
What a difference "broadband" made! Instead of 56 kilobit/s, we had 4
megabits/second speed, almost 75 times faster and always on 24/7!
Uploading was also spectacular, 1 Mb/s. The speed made the expensive T1
line at the office seem really slow.
Today, we still use a cable modem and our service provider is the local
CATV company. We get about 300 Mb/s download but only about 10Mb/s
upload, the major downside of cable modem service. Otherwise, the HFC
network is plenty fast and reliable, which makes
us less unhappy that we can't get FTTH.
You can see the actual hardware in the photo below. The video gives an insider's story of the development.
Gene O'Neill tells the story of working with
LanCity to develop the cable modem. The big box was the prototype we
tested on the school I-Net (institutional network) coax cable TV system.
The smaller gray box he is holding is what was installed in our home by
Continental Cablevision in February 1997. Watch the Video on YouTube.

FOA Support For Educational Outreach
FOA has a program to provide educational materials including plastic
optical fiber (POF) to teachers so they can demonstrate how fiber optics
works to their students. We also have videos about how fiber is used
for communications that tell the story of how fiber optics makes the
world's communications networks work.
Indeed these programs are useful in K-12 grades; the kindergarten kids
can enjoy the visual demonstrations of how fiber transmits light and see
how fiber works and students at higher grades can be inspired by the
more technical materials and videos to create science projects or,
hopefully, investigate careers in telecommunications.
Some of the teachers we send FOA demo packages send us videos, like these from Professor Herbert Winful,
University Diversity and Social Transformation Professor, University of
Michigan. Professor Winful was asked to speak to some middle
school and high school students about fiber optics. FOA provided him
with the teaching kit we provide to educators and he sent video of his
demo to one class.
Professor Winful takes his popular demos to
many groups to inspire young people to get interested in science and
technology. One of these is Downtown Boxing and Gym
in Detroit. DBG is a leading, free, out-of-school time program centered
around student achievement and success. By empowering students to
learn, grow and pursue their passions, they are building a brighter
future.

FOA Adds Fiber Optic Network Design in Spanish
FOA is an international organization so we have
expanded our website, textbooks and training curriculum to other
languages, with Spanish being the most popular. We have recently
translated the curriculum for CFOS/D Fiber Optic Network Design into
Spanish for our schools in Spain and the Latin and South American
countries. We also have schools teaching in Spanish in the US.
The FOA Design textbook is available in Spanish also.
The FOA CFOS/D curriculum in Spanish includes the necessary materials
for an instructor to present the course in Spanish and give thCFOS/D
certification exam in Spanish. The material is available to any
FOA-approved school. For more infirmation on becoming a FOA approved

FOA Guide To Fiber Broadband Is A Hit With Broadband Planners
How does broadband work? Without fiber optics it would not work; even wireless has a fiber backbone.
This book is not the typical FOA technical textbook - it is written for
anyone who wants to understand fiber broadband or fiber optics or the
Internet. It's also aimed at STEM teachers who want to include
communications technology in their classes. This book will try to
explain not only how fiber broadband works, but how
it was developed. It is intended to be an introduction to
communications technology
appropriate for a communications course at almost any level (junior
high, high school or
college,) for managers involved with broadband projects, or for anyone
who just wonders how all this stuff works.

| Trying To Mess Up A Good Thing
Before you read this, you should read the two news reports about
Kentucky below. Kentucky Wired may be the most successful public network
project in the US. Within months of the completion of the backbone,
good things started happening around the state. Of course it had to
weather state politics all along, but those in charge understood the
importance to the people of Kentucky.
But not everybody sees it that way.....From Community Networks
Harmful New Bill Aims To Undermine Popular Kentucky Utility’s Broadband Success
A looming new bill by Republican Kentucky State Senator Gex Williams
could undermine decades of broadband progress made in the state’s
capital city by a popular locally-owned utility, Frankfort Plant Board (FPB).
Home to 28,000 Kentuckians, local residents and utility officials
in Frankfort are incensed at the bill, which they believe will
unnecessarily result in higher rates, fewer jobs, and less broadband
competition overall.
Williams is circulating a bill in the Kentucky state legislature
that, if passed, would force FPB to sell its broadband division to a
private-sector company and subject it to more stringent oversight
requirements. In guest editorials circulated in the local press,
Williams insists his goal is to “rein in” the FPB, which he deems part
of a “runaway” government that lacks accountability.
But there’s no evidence for Williams’ allegations of limited
accountability, and locals and activists alike believe that the
legislator is simply running interference for regional broadband
monopolies upset by the added competition created by the popular,
publicly-owned utility.
From Community Networks
Williams is not unbiased. According to his LinkedIn profile, he has worked as an IT
consultant, Wireless Internet Service Provider, Wi2, Sep 1998 - Jan
2022 · 23 yrs 5 mos. Wi2 is an IT consulting company and a Wireless
Internet Service Provider (WISP) delivering high speed wireless internet
service to rural customers who are under served by traditional wired
internet service providers (DSL and Cable). Wi2 operates in the
unlicensed spectrum using commercial and retail devices conforming to
FCC Part 15 regulations.
The city of Frankfort has strongly rejected the idea and passed a resolution of support for FPB and FPB has an online petition you can sign supporting them.
This is not the first time state legislators and lobbyists have tried to
ban municipal or utility broadband. They even tried to ban wireless in
one state. Perhaps state politicians should go back to trying to
legislate the math constant pi to equal 3 instead of listening to
lobbyists.
Kentucky Schools Jump From #49 to #5 In Connectivity In One Year
FOA has written several times about our role in helping Kentucky develop
a workforce to build their fiber optic backbone network "Kentucky
Wired" to connect all 95 counties. The backbone was completed a year
ago, and the workforce built around the 1,200+ CFOTs trained by 9
Kentucky Community and Technical Colleges (KCTCS) was spread all around
the state, ready to build the connectivity needed by government
agencies, schools, and commercial customers.
Graphic: Connected Nation
And build connectivity they did. In one year, Kentucky schools jumped
from ranking 49th in the US in connectivity to 5th with 97% of all
school districts having access to Internet connectivity at 1Mb/s per
student or above.
Graphic: Connected Nation
That's the power of fiber optics but also the results of wise planning
and understanding the value of investment in infrastructure. When FOA
met with KY Wired officials, contractors and KCTCS schools in 2015 to
create a workforce development program in Kentucky, it was unclear if
such an ambitious infrastructure program could really happen. But KY
Wired survived political changes and cost issues and really shows the
value of investment in fiber optic communications infrastructure pays
off.
But that's not all....
Gov. Beshear: Kentucky Ranks No. 5 Nationally for Business and Infrastructure Investments
Gov. Andy Beshear announced Kentucky ranks fifth in the nation for business and infrastructure investments in Site Selection magazine’s 2023 Global Groundwork Index.
The ranking factors in business investments that generate jobs, as well
as infrastructure investments that help Kentucky families by providing
high-speed internet, cleaner water and safer roads and bridges.
Graphic: Site Selection magazine
Site Selection magazine also noted the cooperation between states,
especially Kentucky and Ohio. Ohio is a very progressive state also and
is creating programs in their education system that will also make a big
difference in the fiber optic workforce needed for the future. FOA will
report on those projects soon.
References: Connected Nation and Site Selection magazine
WORTH NOTING - THE IMPORTANCE OF BACKBONE AND MIDDLE MILE NETWORKS
All the industry's focus has been on
broadband for the home, which these two articles about Kentucky shows is
shortsighted. Fiber broadband to the home has no possibility without a
strong fiber backbone to connect to. The same applies to 5G cellular.
The success of Kentucky Wired shows the importance of backbones and
middle mile projects being undertaken in other states like California.
Perhaps these two success stories will help overcome the fiber to the
home hype and widen the points of view of the users and the industry.
The Geopolitics of Submarine Cables
Most of the time when we mention submarine cables, it is because some
new cables are being installed or some new technology has been
introduced. But this video from ABC News, and Australian public
broadcasting network takes a different viewpoint, the geopolitics of
undersea communications networks.
It's called "The Cloud Under The Sea" and it's described this way: "Lurking under
the sea is a global web of fibre optic telecommunication cables, the
plumbing of the internet. It's how we talk, text and stream, connecting
billions of people. These cables are also the frontline of a tech war."
Telegeography's Research Director Alan Mauldin is well-versed he
is in submarine cable geopolitics and in cable knowledge in general.
Alan shares his expertise throughout this submarine cable documentary,
The Cloud Under the Sea, which, according to Telegeography
“uncovers the shadowy world of telecommunication sea cables.”
From the video we learned some interesting statistics: that there are
about 500 undersea cables, only 4 undersea cable manufacturers, about 60
cable laying ships and they are kept busy laying new cables and
repairing current ones, which happens about every 3 days. And these
cables carry communications representing about $10 TRILLION each day in
commerce. They are indeed important!
If you are interested in the impact of worldwide communications and the
geopolitics involved, including spying and sabotage, you will find this
58 minute video highly interesting and entertaining.
Watch it on the Telegeography website.
Are Shark Bites The Cause Of Submarine Cable Failures? (See article above!)
That is one of the favorite myths of fiber
optics; something instantly believable since sharks are one of the most
villified creatures on this planet. That myth is examined by Geoff
Bennett of Infinera in an interesting article in ISE Magazine.
"Like any good urban myth, there is a smattering of truth at play...the
magnetic fields emitted by underwater cables of all types attract those
“evil” sharks, potentially causing them to bite into cables and
creating a world of problems for the service providers who are sending
vital traffic over them."
According to reports by the International Cable Protection Committee
(ICPC), there are between 100 and 200 incidents of damage to cables
around the world each year, but on average only four of those involve
deep water sections of the cable—which would be the most expensive and
time-consuming to repair. All the others occur in shallow water—but how
many of them are caused by sharks?
Graphic: ISE Magazine
Here is a breakdown of cable faults for all types of submarine cable
from 1901 to 2020. As you can see, well over two-thirds of cable outages
are man-made in some way. And shark/fish bites have happened but
represent a small part of the problems, most of which are man-made.

Calix Creates Online Training For Service Providers
FOA has always been focused on the cable plant and
its design, installation and operation, but the equipment that
communicates over that cable plant is also very important. Calix is one
of the major providers of broadband communications equipment and they
understand the importance of training also. They have created the online
"Calix Broadband Academy"
to educate broadband service providers about the five stages of
building a successful broadband business. The five stages include the
three FOA focuses on, design, installation and operation, but adds two
critical areas faced by a broadband ISP running a business, funding the
operation and marketing to the customers.
Calix has created a Broadband Academy eBook
that covers the same material in a format that ie easy to share among
others in the agencies working on developing a broadband program.
And they hold the ConneXions conference annually and more virtually for service providers.
At the Calix ConneXions 2023 conference last Fall, FOA provided copies of the FOA book on Fiber Broadband to
hand out to attendees at a "Train The Trainer" session where broadband
leaders learned how they can deliver meaningful and fun broadband
education to their communities.
At the Calix ConneXion Confrence, attendees were given copies of the new FOA Guide To Fiber Broadband
At this session Calix announced FOA's Fiber U as their "Install and Repair" curriculum of choice for Calix customers

FOA Curriculum For Schools Adds Fiber Optic Network Design in Spanish
FOA is an international organization so we have
expanded our website, textbooks and training curriculum to other
languages, with Spanish being the most popular. We have recently
translated the curriculum for CFOS/D Fiber Optic Network Design into
Spanish for our schools in Spain and the Latin and South American
countries. We also have schools teaching in Spanish in the US as you can
read below.
The FOA Design textbook is available in Spanish also.
The FOA CFOS/D curriculum in Spanish includes the necessary materials
for an instructor to present the course in Spanish and give the cfoS/D
certification exam in Spanish. The material is available to any
FOA-approved school. For more infirmation on becoming a FOA approved
school, go here.
Quote Of The Month:
(several months ago actually, but this is worth repeating)
Speaking at the Goldman Sachs Communacopia +
Technology Conference, AT&T’s CEO John Stankey said, “There’s a
fallacy to say there’s fixed networks and wireless networks. There are
only fiber networks with different access technologies on the end of
them. That’s where this is all going.”

Is Aerial Installation Really Easier And Cheaper?
We watched these techs overlashing a cable in Santa Monica recently.
Unfortunately for them, they were adding another cable to a bundle of
other cables that includes as many as 10 cables along the street where
they were working, For installers, this bundle has many obstacles - many
poorly installed cables drooping from improper lashing, many splice
closures, drop cables, and snowshoes from service loops left by earlier
installers.
In the photo above, you can see the tech on the ladder leaning against
the pole (would OSHA approve?) assessing how to proceed crossing the
cables running down the alley between the buildings.
We watched these techs for almost half and hour and they did not get 50
feet (~15m) of cable installed. Trees growing around the cable meant the
lasher could not be pulled from the ground so it was manually moved by
the tech in the bucket. In the lower photo you can see how he was
pushing tree limbs aside to clear the lasher (arrow on the right) and
then had to work his way around the snowshoe on the left.
This was a far as they got that day. We hope to see
them when they return. Negotiating the next section of the same cable
bundle, just one pole down, should be interesting.
Makes you wonder about the wisdom of "one touch make ready," doesn't it?
NECA/FOA 301 fiber optic installation standard
withdrawn
The NECA/FOA 301 fiber optic installation standard has been
withdrawn. It's almost a quarter century old and a decade since the
last update. It has been decided the standard needs to be replaced with a
more modern document covering current technology and written in a
format that allows easier updating.
In the meantime, there is lots of useful information in the standard and you can still download a free copy from FOA.

Installation of FTTH active equipment
Once the PON cable plant is installed and tested, the network
electronics can be installed. The OLT is installed at the headend and
each OLT port connected into the fiber to the designated service area
and the splitters installed to serve the intended users. At each user
location, an ONU or ONT is installed to complete the network and connect
to a wired or wireless network in the user’s location.
In this paper, engineer Vladimir Grozdanovic explains the different
types of equipment and how they are installed to create an operating
PON.

Sticklers Introduces "Touchless" Connector Cleaning
The Sticklers™ Pro360°™ Touchless Cleaner is a unique end face connector
cleaning tool that quickly and completely clean oils and dust across
the entire end face of both male and female connector ends, with just
the press of the connector cleaner handset. A hand-held connector
cleaner handset delivers a micro-dose of atomized cleaning fluid within a
narrow column of pressurized air onto a fiber optic connector endface
thoroughly cleaning the entire connector endface in less than 4 seconds.
Unlike click-to-clean tools, the Sticklers™ Pro360°™ Touchless Cleaner
makes no physical contact, thus eliminating scratching or pitting
potential. This method thoroughly cleans the end-face all the way to the
ferrule edge. The connector is left perfectly clean and dry, with no
contamination to migrate into the contact zone and block the optical
signal.

Learning Important Information From A Found Cable Scrap
While walking down the street near the FOA office, we found this cable
laying in the gutter. What a find! A short length of Corning Rocket
Ribbon 864 fiber cable left over from an installation by a contractor.
We brought the cable back to our office with the intention of opening it
up and creating a video about the construction of this modern high
fiber count cable, but something got our attention first. The cable had a
very
long line of printing on it with lots of interesting and useful
information. So before we started deconstructing it, we decided to
photograph the printed information and interpret it. That turned out to
be an important part of the information we learned from the cable. Then,
as you will see below, we dissected the cable and learned even more.
Red more about what this cable marking tells you and what the cable looks like when you open it up to prepare for splicing.
Problems With Old Cables And New High Fiber Count Cables?
A FOA CFOT reported that they have been doing fiber characterization
testing on cable plants that include both old and new fibers, a common
result from building out from a legacy cable plant. One surprising
result was that some relatively short links are showing CD and PMD
problems even when only short segments of the cable plant are older
fibers. PMD has become an issue as speeds increase but earlier fibers we
not optimized to prevent PMD. This is just another reason to do fiber
characterization before trying to upgrade network speeds. (There is more
information on Fiber Characterization in the FOA Guide and a fiber characterization course on Fiber U.
We're also hearing rumors that the new high fiber
cables are getting fibers broken
during installation with the possible cause(s) being exceeding bend
radius or pulling tension, using improper installation equipment or
maybe even the cable designs. We're investigating this and will report
back in the near future. But please ensure installers follow
manufacturer's recommendations carefully. Check out the information on
cable specs in the article in this issue and the article on Bending Diameter in the FOA Guide.
Managing Fiber Optic Projects - The Gantt Chart
(With An Excel File To Make Your Own)
The most common way to track projects is the Gantt Chart, a
chart of activities that tracks the progress of projects along a
timeline. each activity is represented by a bar and the position and
length of the bar represents the starting date and duration of the
activity. This allows you to see what activities are needed for the
project, when the activities start and end so it can be used to track
the progress of the project visually. Here is what a Gantt Chart for a
fiber project might look like:
You might remember an article in the FOA Newsletter in April 2022 or the FOA Guide page on Project Management about the timing of a fiber optic project where we showed the progression of steps in a project like this:
The Gantt Chart above is simply this list converted to a Gantt Chart
using a Microsoft Excel spreadsheet. You can download a copy of the FOA Gantt Chart spreadsheet (xlsx file - 16kB)
and use it to create your own Gantt Chart for any project. All you have
to do is to input your own data and change the activity names as
necessary. You can also follow the directions from Microsoft to create your own version.
More Help On Color Codes (Including Copper Cabling And Fiber Optics)
The FOA has created a print-your-own pocket guide to fiber
optic color codes. It has
color codes for fibers and buffer tubes, connectors and premises cables
inside and on the back, QR codes to take you directly to the FOA Guide
and Fiber U. The FOA
Guide page on Fiber Optic Color Codes is one of the most read pages on the FOA
website and the Fiber Optic Color Codes minicourse on Fiber U very popular also.
Here's a do-it-yourself FOA Guide To Fiber Optic Color Codes card.
Just download the PDF file, print it on a color printer and fold it up
as shown. Then you have your own pocket guide to color codes. Make a
bunch for your co-workers too.
Then we realized that many of your also do structured cabling
work, so it was a natural to add a Color Code Guide for UTP copper
cabling in printable (below) and electronic (above) versions.
But we did not stop there. We know how many of you use your mobile devices on the job, so we created a version of the Color Code Guide you could download
and use on your smartphone or tablet. It's a PDF file, so you just
download it and save it on your device and it will be with you always.

Warning For Techs Doing OSP Restoration
FOA received an inquiry about whether techs
working on restoring OSP links should be concerned about eye safety if
the link used fiber amplifiers. To answer this question, we had to do some research on fiber amplifiers.
The short answer is YES, you should be concerned. The long answer is
more technical and includes details that every OSP tech needs to know.

Good Question!
Tech
Questions/Comments From FOA Newsletter Readers
Fiber Loss Budget
Q: For a fibre of total distance of 160km, what should be the standard total loss per kilometre?
A: The typical loss for SM fiber is ~0.35-0.4 dB/km at 1310 nm or
~0.15-0.2 dB/km at 1550. We assume a system like this will be using
1550 nm. You can use the FOA online Loss budget Calculator
https://foa.org/tech/ref/Loss_Budget/Loss_Budget.htm to estimate the
total link loss
Reuse Of Cable Being Removed From Service
Q: Is there ever a feasible reuse for used/older fiber optic cable?
Would some one be in the market for the FOC that is removed from
service? Lets say 20year old aerial cable ADSS?
A: We have been asked that question a lot. It often involves cheap
fiber on eBay or from surplus dealers. With the advances in fiber
technology and manufacturing, 20 or even 10-year old fiber is
essentially obsolete. Lots of service providers are replacing that fiber
with today’s higher performance fibers because networks are going from
the ~2 gigabit speeds then to terabit speeds today. We would never
recommend reusing fiber removed from service. You have no knowledge of
how it was installed originally and environmental conditions can be hard
on some types of cables. Besides, the cost of the cable is only 5-15%
of the project cost. Most of the cost is in the labor of installation so
the savings would be minimal and the risk high.
We have been telling people who have leftover cable from projects to
offer it to FOA schools. They are always in need of OSP cables.
Minimizing Latency
Q: Latency a term that is widely used today. If we manage to
make the light travel without interruption we will achieve that the
speed is perfect, but the equipment (router, OLT, firewall, etc)
generates a processing that takes some time, do you think that LATENCY 0
will be achieved?
A: The work on achieving minimal latency has been gong on for
decades, primarily driven by the computerized stock traders who rely on
microsecond trading. One recent project used an experimental fiber with a
hollow core becasue light travels 50% faster in the air than glass.
Most low latency networks try to use the longest fiber links possible
using submarine cable technology because the electronic switching takes
too much time. But most electronics require digital signal processing in
the transceivers which takes time, switches to the trading computers
takes time and while you can minimize it all, it can never reach “0”.
Microtrenching
Q: What is microtrenching?
A: Microtrenching is a technique for installing underground
fiber. It is done by sawing a groove in the road or sidewalk and
dropping a small (~1/2 inch or 13mm) plastic tube (duct) into the
groove and filling it up with material like the surface so it almost
disappears. The cable is “blown” into the duct with high pressure air -
actually the air floats the cable in the duct to reduce friction and the
cable is pushed into the duct.
Here are photos of a microtrenching installation in Toronto. Here is the explanation of microtrenching in the FOA Guide section on OSP Construction (about 3/4 down the page.)
We don’t think any of our schools teach this in the US but Triple Play does in South Africa.
In the US we recommend going to one of the companies that makes the construction equipment, primarily Ditch Witch.
Previous Questions
Degraded Underground Fiber Optic Cable
Q: How can you handle a degraded buried
underground fiber link, which has degraded due to multiple joints
introduced during maintenance?
A: If it has reached a point where the loss or dispersion limits its use, it probably should be replaced.
Maintaining Fusion Splicers
Q: What are the best practices for the preventative maintenance of splicers, cleavers, and thermal strippers.
A: Because of the large number of manufacturers and variety of
models and applications, The FOA generally tells people to follow the
manufacturer’s directions for use and be especially careful about
keeping the splicer unit, cleaver and stripping tools clean, then having
it serviced regularly by the manufacturer or an authorized service
facility.
Rural FTTH
Q: What does A Rural FTTH Connection Cost?
A: That's a very complicated question, because "rural" has a lot
of meanings. Is it a small town where building a FTTH Network is easy or
remote users in Alaska? An interesting set of data was made available
this month from the US Department of Agriculture, announcing $700
million in grants and loans in the 4th round of the ReConnect Program https://lnkd.in/gFe9T4b7.
Splicing Dissimilar FIbers
Q: Recently I came across a new problem while splicing optical fiber
cable. Splicing of 2 Fujikura fibers was done but loss was
observed. Initially, we felt that it is due to splicing but upon
resplicing the loss was still the same i.e. 0.3db at the splice point.
Both the cables were checked again and observed that both cables were
from different manufacturers. My question is that if different
manufacturer's cables are spliced, will it give loss? Note: Both fibers
were Fujikura but had different IOR.
A: The difference in IOR tells the reason. The loss at the joint
between the two fibers when measured by an OTDR depends on the optical
characteristics of the fibers. A difference in the fibers IOR and
backscatter coefficient will cause the loss measurement to be affected.
In one direction it measures too high, in the other direction too low or
even shows a gain. That’s why some measwurements are called gainers. If
you measure it in the opposite direction you should see low loss or a
gain. It’s explained here in the OTDR page on the FOA Guide https://foa.org/tech/ref/testing/OTDR/OTDR.html in the section “OTDR Measurement Uncertainty.”
Testing FTTH Networks
Q: I work on FTTH projects that utilize 1x32 and 1x64 splitters that
do not have any active light on the fibers. Is there a mobile source
that can be used in the field to simulate active light through splitters
and still provide enough power to travel 20km?
A: Any 1310/1490/1550 test source should have adequate power to
test them with a regular power meter. A 64 port splitter has only
18dB+any excess loss- so 20dB or so - and any power meter can measure
that with a ~0dBm to -6dBm source.
More on testing FTTH Networks
OTDR Dead Zone
Q: What is dead zone when using OTDR?
A: The "dead zone" is the length of fiber near the OTDR that is
blanked out by the overload from the test pules. See this page on OTDRs
in the FOA Online Guide: https://foa.org/tech/ref/testing/OTDR/OTDR.html
Using A Visual fault lOcator
Q: What are the best practices for using a VFL to locate fiber faults?
A: See https://foa.org/tech/ref/testing/test/visual.html in the FOA Online Guide
Fiber Splicing Cost
Q: What is the standard of costing for fiber splicing and
terminations? Is it per core / per splice or per each cable end
irrespective of the number of cores?
A: That is a very hard question to answer, other than to say ”it
depends. ” The number of fibers is definitely a factor because each
fiber must be stripped, cleaned, cleaved and spliced then placed in the
splice tray.
It also depends on:
- Single fiber or ribbon splicing?
- Type of splice closure
- Type of cable (loose tube, ribbon, flexible ribbon, high density, armored, ADSS, etc.)
- Installation: aerial or underground
- Location: urban or rural
- Set up time (same for low fiber count cable as high fiber count cable)
Most contracts will be considering the number of
fibers but also these factors, and probably they want to price by the
number of fibers, but the price per splice will vary accordingly. We've
seen quotes in the US for prices varying over a 10X range.
FTTH Network Design Course
Q: I would like some advice on how to develop a responsive curriculum involving FTTH network design.
A: FOA has lots of free resources you can use. Fiber U
offers free online courses in FTTH and Fiber Optic Network Design that
can be used to develop your courses using blended learning - online and
classroom work blended. The courses cover all aspects of these topics
and include lesson quizzes. The Design course includes a dozen case
studies ideal for student assignment, including one on FTTH. You can
also begin with other courses like Basic FIber Optics and Outside Plant
Fiber Optics and Outside Plant Construction. The Fiber U courses draw on
material in the FOA Online Guide where you will find many other pages of useful information.
Teaching a course on FTTH and FTTH Network Design is easy using this
material. The Design labs don’t require equipment; just use the case
studies we provide and develop more of your own.
Markers Required For Underground Fiber Optic Cables?
Q: Are signs required for underground cables like fiber
optic cables? Are they required to have signage so people don’t dig them
up or damage them?
A: In the US the answer is NO. There is no Federal or State law
which requires marking anything other than hazardous liquids and gases.
It is purely a business decision or a moral decision to invest in
signs/markers to protect buried fiber. If a fiber gets cut it can
disrupt 911 service and all kinds of vital communication related to
hospitals, air traffic control, etc.
Fiber Optic Color Codes Reference Chart
Q: Has anyone made a fiber optic pocket reference chart that has cable
color orders, frequencies, or other commonly used info on it?
A: The FOA has a page on its Online Guide that covers color codes
(https://foa.org/tech/ColCodes.htm). It is the most popular page in the
FOA Guide! It works great with a smartphone.
The
word on the "Dig Once" program is getting out - FOA
is getting calls from cities asking us for
information and advice. Here are some links:

Is There A Standard
For Fiber Optic Installation?
Note: NECA/FOA 301 has been withdrawn. It's almost a quarter century old
and a decade since the last update. It has been decided the standard
needs to be replaced with a more modern document covering current
technology and written in a format that allows easier updating.
In the meantime, there is lots of useful information in the standard and you can still download a free copy from FOA.
A
question we get often is "Is there a standard for
fiber optic installation." The answer is yes, but
not from the usual standards groups you might
expect. Over 20 years ago, the National Electrical
Contractors Association (NECA) asked FOA to help
create a standard for installation. That standard,
ANSI/NECA/FOA-301 has been updated three times
already and is about ready for another update.
Unlike most of those groups who charge you a fortune
for standards, FOA covers the cost so ANSI/NECA/FOA-301
is available free from FOA.

The Types of Work Done By Fiber Techs And How It Affects Training
What is a fiber optic technician? What kinds of work
do they do? Those topics were the center of FOA discussions with the US
Department of Labor Bureau of Labor Statistics that led to the new job
category of "Telecommunications Technician" on the BLS
website. The focus of this job category is primarily the
installation and operation of the fiber optic cable plant, but one
should not forget the cable plant must be designed also as part of a
more extensive communications network.
In our discussion with the BLS analysts, we pointed out the various
stages of a fiber optic communications network project and how techs
with various knowledge and skill sets are needed and involved in every
step. Here is how FOA defines these stages of a project and the skills
of the techs. This is not unique to FOA; it's what has been traditional
at telecom companies forever.
Planning and Design: Once needs for a communications network is
established, project managers will be responsible for all the details of
the project while experienced fiber techs trained and experienced in
fiber optic network design (CFOS/D) will design the cable plant itself. (FOA Guide - Design)
Construction: Aerial cable plants may require installing new poles or
doing make-ready on existing poles and messengers. Underground
construction requires trenching and installation of ducts. In many cases
the actual construction is done by general construction workers, as the
construction work in many cases is not unique to fiber optics. Heavy
machinery is required for much of the construction work and training is
focused on safety as well as operating the machinery. (FOA Guide - Construction)
Fiber Optic Cable Installers: Once the route is prepared, the fiber
optic cable can be installed. Aerial cable installation depends on the
type of cable. Regular OSP cable, figure 8 cable and ADSS cable requires
special hardware and installation techniques so the techs must
understand the process appropriate for each cable. (FOA Guide - Installation)
Splicers: Since the beginning, fiber techs have been called
"splicers"
because that was the original job unique to fiber optics. Construction
and cable installation was not very different from earlier copper
cables, but splicing was very different. Even today, fiber techs are
often called splicers and splicing is a core skill for any fiber tech
whether they are joining cables or terminating them. (FOA Guide - Splicing)
Testers: After the fiber optic cable is installed and spliced,
it must be tested. Testing goes together with splicing since every
splice will be tested, often as soon as it is made so if it needs
redoing, it should be done before the splice closure is sealed. (FOA Guide - Testing)
Network Operators: Once the cable plant is built and the communications
equipment installed, it needs techs who know how to operate the comms
but may only know how to connect new gear or change connections on
current gear. These techs should also know how to troubleshoot systems
in an outage and either do the restoration themselves or call a tech who
can. (FOA Guide - Operation)
These categories merely define the stages of installation of a fiber
optic project. Of course there are subsets of these categories and most
fiber techs are expected to have skills and jobs that cross into
multiple groups, as FOA has defined in the KSAs (knowledge, skills and abilities) for a CFOT.
What an individual worker does differs according to their job. An
independent fiber contractor may cover every job except
operation and a FTTH subscriber installation tech may only understand
installing cables, testing and connecting equipment within the scope of
FTTH systems. A construction company may handle the trenching and even
pole setting as well as parts of the traditional fiber work.
The FOA defined its role early on to focus on educating and
certifying techs in the fiber specific skills: cable installation,
splicing, testing and restoration. FOA would like to see more schools
get into the construction phase, especially for newer techniques like
microtrenching and blowing cable, but these require large outdoor areas
for training and large investments in equipment. Most techs who learn
these processes now do it with OJT - on-the-job-training - and hopefully get OSHA
training for safety.
FOA School News
FOA's roster of approved schools is growing as more organizations
recognize our expertise in workforce development and our comprehensive
support for getting new schools started. FOA has over 25 years
experience and nearly 100,000 certified fiber techs (with ~130,000
certifications). As a non-profit organization founded by the industry
specifically to develop a competent workforce, FOA provides the
consultation, curriculum and contacts to get schools started as a free
service to new schools.

Need A Fiber Optic Course Onsite? Invite an FOA School To Come To You
FOA often gets inquiries from an organization that
has personnel that needs training in fiber optics. Recent inquiries have
included contractors, a manufacturer of high-reliability products using
fiber optics and a cable manufacturer. In many cases, where there are
several people needing training, FOA can recommend a FOA Approved School
and Certified Instructor who will come to their location to teach a
class. The advantage is of course the savings in travel costs if
the class comes to you, but it also offers the opportunity to customize
the course to fit your needs, even use your equipment or work on your
components, so the training is more relevant to those taking the class.
Contact FOA to discuss the idea of a custom, on-site class to see if it will better meet your needs.
Fiber U
On-The-Job Training (OJT) Program
The
FOA Fiber U OJT program for novices combines online study at
Fiber U with OJT with mentoring by experienced
co-workers and their supervisor to help new employees
develop into experienced FOA-certified technicians.
The FOA Fiber U “OJT-To-Cert”
program includes both fiber optics
and premises cabling (copper, fiber & wireless),
so it covers techs working in both outside plant and
premises jobs.
Like other FOA
programs, the OJT-To-Cert program is free. If you
and/or your company is interested in the FOA
OJT-To-Cert program,
contact FOA.
To explain how OJT
works and FOA's OJT-To-Cert program, FOA created a

New Fiber U Course: Fiber Characterization
FOA has added a new course at Fiber U on Fiber Characterization. Fiber
characterization is the process for testing long fiber cable plants for
its ability for carrying high speed communications. With so many
networks now operating at 100, 200, 400 or even 800 Gb/s, fiber
characterization is important, especially on older fiber optic cable
plants.The free Fiber U Fiber Characterization course is available in two forms, as a standalone Fiber U fiber Characterization Course with its own Fiber U Certificate of Completion and as a separate Lesson in the Fiber U Fiber Optic Testing course. This course is recommended for those studying for the FOA CFOS/FC Fiber Characterization certification.

What Fiber Techs
Don't Know -
What We Learn From
FOA Certification Tests
As
FOA moves more testing over to our digital online
testing system at ClassMarker, we have access to
more data about our testing, including what
questions and topics on the tests are answered
incorrectly most often. Having this data gives us an
opportunity to evaluate the questions and how they
are stated, but more importantly it allow us to help
our instructors teach the subjects and us to change
our curriculum and online courses to emphasize these
particular topics. These are some of the topics that
we have noticed are answered incorrectly more often
in FOA and Fiber U tests.
Most of the questions missed are on testing.
1. OTDRs - particularly what information is in the
OTDR trace.
2. The difference between dB and dBm
3. Loss budgets - both the concepts and doing the
math
4. Insertion loss testing - single-ended or double
ended for testing patchcords or cable plants, how to
set 0dB references
5. Units of measure - fiber is measured in microns,
wavelengths in nanometers, etc.
At FOA, we're working to add Fiber
U MiniCourses on these topics and working with
our schools to emphasize these topics in their
classes.
If you are going to be taking a FOA certification
course or test in the near future, these topics
should be on your final exam study list.
What We Learn From Hands On Labs
We learn about students performance in hands-on labs
from the feedback of our instructors and our own
experiences too. One big problem is the use of hand
tools. Growing up today, you learn how to use
keyboards, mouses and touch screens, but decades
ago, you also learned how to use basic hand tools.
This is big enough of a problem that we're
considering adding some video lessons on basic hand
tools to prepare students for cable prep,
termination and splicing that require the use of
hand tools.
FOA offers free online self-study programs at Fiber U.
Many users are preparing for FOA certification
programs - taking courses at our schools or using
the Direct Certification program. Some of our
schools are requiring Fiber U programs as
prerequisites for their classroom courses so they
can spend more time on hands-on activities.

Latest FOA Book: Fiber Broadband (Paperback and Kindle)
In less than half a century,
fiber optics has revolutionized communications and to a large extent,
society in general. Broadband, what many today call high speed Internet
access, has become a necessity for everyone, not a luxury. The
technology that makes broadband possible is fiber optics, connecting the
continents, cities, and just about everybody. Even fiber to the home
(FTTH) brings broadband to hundreds of millions worldwide.
How did we get from an era when communications was making a telephone
call or sending a telegram to today’s world where every piece of
information – and misinformation – is available at the click of a mouse
or touch on a screen? How did we get from a time when a phone was
connected on copper wires to being able to connect practically anywhere
on a handheld device with more computing power than was available to
scientists and engineers only decades ago?
How does broadband work? Without fiber optics it would not work.
This book is not the typical FOA technical textbook - it is written for
anyone who wants to understand fiber broadband or fiber optics or the
Internet. It's also aimed at STEM teachers who want to include
communications technology in their classes. This book will try to
explain not only how fiber broadband works, but how
it was developed. It is intended to be an introduction to
communications technology
appropriate for a communications course at almost any level (junior
high, high school or
college,) for managers involved with broadband projects, or for anyone
who just wonders how all this stuff works.

Your
Name, CFOT® - It pays to advertise!
The FOA encourages
CFOTs to use the logo on their business cards,
letterhead, truck or van, etc. and provides logo
files for that purpose. But we are also asked
about how to use the CFOT or CFOS certifications.
Easy, you can refer to yourself as "Your Name,
CFOT" or "Your Name, CFOS/T" for example.
Feel free to use the
logo and designations to promote your achievements
and professionalism!
Contact
FOA at info@thefoa.org to get logos in file format
for your use.
