-
-
- FOA President Jim Hayes and
the FOA have been recognized for their efforts to promote FTTx,
particularly in the multi-dwelling unit (MDU) market by Broadband
Properties magazine. The importance of our work promoting FTTx
education and recruitment through our certifications, online
programs and FTTx Summits was recognized by BBP. Read

Minicipal WiFi Not Fulfilling
Promises (or Hype)
Many cities have been considering
(or are already implementing) municipal WiFi networks. A recent
independent survey of municipalities by the International Economic
Development Council, which
you can download and read for yourself, is much less optimistic
about the benefits of municipal WiFi and underscores the lack
of understanding among municipal implementers regarding the technical
and support issues. One of the major conclusions is that wired
networks have a much greater impact on attracting, retaining
and improving businesses in the area. But an even more important
conclusion is municipalities "definitely don't understand
the amount of support services, training, etc. needed for the
technology to produce meaningful impact."
That last statement could also
be relevant for those municipalities considering creating their
own FTTx programs. Our work with Verizon indicates that they
have learned that installing fiber optics is only a small part
of the whole program. Their recruitment focuses more on technical
expertise in installing and providing services at the home and
CO and providing technical support to the users.
Our conclusion from reading this
report is that municipal networks need both wireless and landline
connections, with the landline being the primary conduit for
businesses and homes (especially if they want video-capable bandwidth)
and wireless provided for the convenience of mobile users and
visitors.
- Installing Fiber Optics? Have
You Seen These?
- We get lots of calls here at
the FOA looking for advice. Many are from people unfamiliar with
fiber optics who are planning an installation, having an installation
done or testing and troubleshooting problems. To answer these
questions, we have created a standard on installation, NECA/FOA-301
and three Tech
Bulletins for users and installers. These, plus all the information
in our "Tech
Topics" section, will answer many of your questions.
It's where most of our callers are sent for detailed explanations
they can print and distribute to interested parties.

- 8 Lessons Learned From FTTH
Systems (from Lightwave)
- Now more than 1,000 communities
with over 1,000,000 subscribers have FTTH installed. Over 6,000,000
homes have been passed and more subscribers will sign up as new
services are offered. What have we learned, not only technically
but in terms of markets and subscriber wants and needs? Lightwave
has an interesting article online that talks about bundling services,
branding, and the effects of the housing market downturn. Read More.
More Verizon FTTx News
- FTTx Paying Off For Verizon
- "The fiber-optic broadband
service, FiOS, added 203,000 subscribers in the quarter for a
total of 1.1 million. Of those, 515,000 were also signed
up to get TV through the fiber, a tenfold increase from a year
ago.
For the first time, Verizon signed up more subscribers to get
broadband Internet service through FiOS than through the copper
lines for DSL, or digital subscriber line. It added just 85,000
DSL subscribers, down from 239,000 in the first quarter. ''Frankly,
we weren't as focused as we used to be on DSL for the quarter,''
Strigl said. ''We have taken a lot of the technicians and the
service reps that used to work DSL and tried to quickly get them
up to speed on FiOS.'' Strigl said the company aims to get DSL
customer recruitment numbers back up.

Nanotech Continues Developing
Components Useful For Optical Communications
Researchers at IBM in Yorktown
Heights, MY have developed a new type of nanowire LED that is
both more efficient and emits in the infrared region needed for
fiber optic communications. The wire is only 0.1 micron in diameter
and 10 microns long; the length about the diameter of the core
of singlemode fiber. The devices show some laser characteristics
and one unique feature, they emit more light as temperature rises,
not less as with semiconductor LEDs. The devices are small enough
to incorporate in chips to allow speeding up on-chip signals,
a big problem today with electrical signals getting too fast
for semiconductors. Read

Digging Safely 
The old story (not a joke!) about
the most likely fiber optic communications system failure being
caused by "backhoe fade" reminds us that digging safely
is vitally important. The risk is not just interrupting communications,
but the life-threatening risk of digging up high voltage or gas
lines.
There is a website called "Common Ground Alliance"
that focuses directly on this issue. Here is how they describe
themselves:
- Damage Prevention is a
Shared Responsibility
- The Common Ground Alliance
(CGA) is a member-driven association dedicated to ensuring public
safety, environmental protection, and the integrity of services
by promoting effective damage prevention practices.
In recent years, the association has established itself as the
leading organization in an effort to reduce damages to all underground
facilities in North America through shared responsibility
among all stakeholders.
Of special interest is their
"Best
Practices" Manual, available for downloading. If you
do OSP installs, please get yourself a copy and read it.

Air-Blown Fiber Finally Recognized
In International Standard
Air-blown fiber has been around
for a long time, but has not been widely used in place of conventional
cables, in part perhaps, because it was seen as a proprietary,
non-stnadard, solution to installing fiber. The International
Electrotechnical Commission (IEC) has published the first blown
fiber standard, IEC 60794-5. One obstacle for blown fiber use
has been the lack of a recognized standard for components, installation
and testing. With publication of this standard, it may become
more acceptable to end users wary of proprietary solutions. Read
More. Here is an explanation on it's use from Emtelle.
Home Tech - Needed To Take
Advantage of FTTH
Once a home has a broadband connection,
which we hope is fiber to the home, but could be DSL or Cable
Modem, the usage of all that bandwidth depends on distribution
within the home. The in-home connections can be UTP or Coax copper,
wireless or fiber. But architects and home builders must learn
how to build homes to take advantage of broadband connections.
The FOA, in conjunction with the Structured Cabling Association,
have started working with home builders to bring them up to speed.

- Download This!
-
- There are tons of technical
application notes and videos on the web, and occasionally we
recommend some you should download. The JDSU fiber testing guide
is really worthwhile, as are the ADC FTTx book and Westover video
on fiber inspection and cleaning, linked below.
-
- JDSU Testing Book
 JDSU offers a free download of their
Testing Guide from the Lightwave website. This is one great book
which explains some basic fiber technology, but the real value
is the last half which deals with OTDR testing. Not only does
it give the usual info, but it covers important topics like measurement
uncertainties and anomolies like ghosts and gainers.
-
- I was in the testing business
for 20+ years at Fotec and think this book is one of the best
fiber optic testing texts available. It's complete but comprehenisble!
I used to believe that premises techs did not need OTDR training,
but now OTDR manufacturers are pushing their use in premises
networks. Unfortunately, the limitations of OTDRs in premises
applications can cause extreme problems for those who are not
aware of their limitations. So knowing hows OTDRs work is essential
information to every tech.

- New Professional Society
for Structured Cabling Recognizes Importance of Fiber Optics
(and Wireless)
- The new Structured Cabling Association,
Inc. (http://www.scausa.org/)
is a professional society aimed at installers of "structured
cabling" or premises cabling. Structured cabling has been
focused on so-called "Cat 5" or UTP cabling for years,
while network speeds have left UTP behind. Now most backbones
for LANs are fiber optics and every network seems to have wireless.
The SCA, founded in part by FOA activists Tom Collins and Jim
Hayes, intends to make structured cabling training and certification
more relevant to today's world.

- FOA CFOT Renewals Get Free
Copy of NECA/FOA Installation Standard
- Every CFOT renewal will now
receive a free copy of NECA 301-2004,
Installing And Testing Fiber Optic Cables, produced by
The FOA in cooperation with NECA (The National Electrical Contractors
Association). This is an important reference document for defining
the installation and testing of fiber optic cable plants in a
"neat and workmanlike manner."
- The FOA feels this is such an
important document that we are giving a free copy (normally priced
at $15) to every active CFOT when they renew their active status.
- The FOA has also sent free copies
to all FOA-Approved schools. The new FOA CFOT exam to be used
after August, 2005, will include questions from the standard.
Schools should be including information from the standard in
their classes already.

- FOA Certification Top Choice
The FOA CFOT and CFOS programs continue to gain momentum in fiber
optics. Over 20,000 CFOTs have been certified by over 160 schools
as the FOA enters its 12th year. Since our founding in July,
1995, we have dedicated ourselves to promoting fiber optics and
professionalism in fiber optics personnel, focusing on education
and certification. We are continuing to add new schools and more
CFOTs as users of fiber optics learn that a CFOT is the indication
of a professional, well-trained fiber optic technician. Now with
FTTH (fiber to the home) finally taking off, demand for CFOTs
is rising and schools are responding by expanding programs rapidly.
- The FOA now has approved programs
at 160+ organizations, welcoming new additions like the Joint
Apprenticeship and Training Committee of the International Brotherhood
of Electrical Workers, Corning
Cable Systems and AFL
for their installation training programs and NASA's Goldstone
Tracking Station. The complete list of FOA-Approved schools is
at http://www.thefoa.org/foa_aprv.htm.
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 on this site 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!

Remember To Renew Your Certification
!
Remember to renew your FOA certification.
All current CFOTs have a ID Card with their certification data
and we keep a database of current CFOTs to answer inquiries regarding
your qualifications if needed. You must be a current FOA member
and CFOT to participate in our online
database of installers, contractors, technicians and consultants.

- Tech Puzzler:
There are three ways
to set a "0 dB" reference for insertion loss testing
in order to accomodate the different connectors on cables, patchcords
and test equipment. For example, if all connectors are SCs, a
single cable reference (OFSTP-14, Method B) works. If you are
testing a plug and jack connector like a MT-RJ or FiberJack,
you probably will have to use a 3 cable reference (OFSTP-14,
Method C). Test sets with different connectors from the cable
plant, say LCs in the cable plant, can use a 2 cable refrerence.
(OFSTP-14, Method A). All three methods are generally acceptable
as long as the method is documented, as the results differ. See
this for more
info.

for a complete tutorial on OTDRs and more.
