OLANs In The News
TIA's New High Tech Office Installs Tellabs OLAN
The Telecommunications Industry Association (TIA), the association representing the manufacturers and suppliers of high-tech communications networks, has taken new office space in Arlington, Va. The new office was expressly built to be a high-tech center of information sharing and collaboration for the information and communications technology industry. It features the latest communications technology created by TIA members, innovative ‘green’ features, opportunities for companies to showcase their products and services, and significant meeting space so members can gather to collaborate on standards development, public policy, and more.

The office provides several features to help advance information-sharing and member communications. It has dedicated display and presentation space, providing a unique forum for member companies to showcase their products and businesses. Tellabs contributed an all-fiber Local Area Network (LAN). The Tellabs Optical LAN solution delivers Gigabit data speeds to every desktop, along with the wireless nodes, over a passive fiber network. Tellabs was the first company to donate equipment, and did so in memory of Rob Pullen, its former CEO and TIA board chair, who passed away last year at age 50.
The Tellabs Optical LAN solution deployment includes a fully redundant Tellabs 1134 OLT and Tellabs 709GP ONTs with Power over Ethernet to serve offices, conference rooms and classroom spaces with voice, data and wireless access points. Tellabs also provided the new Tellabs 120W Mini ONT featuring an in-wall installation with a flush faceplate and 2 x 1Gbps interface. Using Tellabs Optical LAN helps the TIA achieve its goals to be a green facility. Compared with a conventional active Ethernet LAN, the solution can save up to 70% in total costs, lower energy consumption by 80% and reduce space by 90%. Tellabs Optical LAN solution is also JITC (Joint Interoperability Test Command) certified for deployment in government networks.
So one should assume that if TIA is using a GPON OLAN in their offices that OLANs are fully standards compliant!
Biggest OLAN at Los Alamos Sandia National Labs
Sandia National Laboratories has become a pioneer in large-scale passive optical networks, building the largest fiber optical local area network in the world. The network pulls together 265 buildings and 13,000 computer network ports and brings high-speed communication to some of the labs’ most remote technical areas for the first time. Sandia, which will spend about $15 million on the project, needs superb computing capability for the problems it tackles as part of its support for the mission for the National Nuclear Security Administration. And it will save an estimated $20 million over five years through energy and other savings and not having to buy replacement equipment. Sandia expects to reduce energy costs by 65 percent once the network is fully operational.
 The Sandia Complex
An optical local area network (LAN) gives people phone, data and video services using half-inch fiber optic cables made of 288 individual fibers, instead of the conventional 4-inch copper cables. Copper cables used to fill up underground conduits and required steel overhead racks of connecting cable, along with distribution rooms filled with separate frames for copper voice and data cables. The fiber distribution system uses only part of the conduit and needs only a 2- by 3-foot cable box. Sandia selected Tellabs of Naperville, Ill., as the equipment vendor for the network.

Sandia is recycling copper as it’s replaced, which keeps tons of valuable material out of a landfill. The estimated $80,000 for the copper will offset some of the fiber optics cost.

AFL Spans 2234 Meters to Reach Peruvian Power Station
AFL’s SkyWrap® set a world record for the longest wrap cable span ever installed and documented the process on video. During an installation in Peru on existing power lines for Consorcio Energético de Huancavelica S.A. (Conenhua), a Peruvian power company, two SkyWrap cables were simultaneously wrapped on an unusually long span measuring 2,234 metres tower-to-tower across a deep valley. “The project took place in the valley of Santa Eulalia, approximately 70 kilometres northeast of Lima in the heart of the Andes Mountains,” explains Carlos Galvez, managing director of Conenhua. “Perilous terrain, lack of access roads and the extremely long span lengths along the route made installation conditions very difficult.”
AFL's SkyWrap solution is a fibre optic cable that is helically applied on existing ground or phase conductors using specially designed installation equipment. The installation span was close to the town of San Pedro de Casta between two pylons each at 3,350 metres above sea level on opposite sides of a river valley. The longest span was just one of 10 spans over 1,000 metres in length on this project. This span was part of a 30 kilometre fibre optic link connecting the Huanza Hydroelectric Power Plant to the Interconnected National Network. The fibre optic cable was installed on the overhead power network owned and operated by Conenhua for Cia. de Minas Buenaventura S.A.A. (NYSE:BVN), one of the major gold and silver producers in Peru. The link will provide a means for control, protection and safe operation of the hydroelectric plant.

US: Best Year For Broadband Since 2008, But...
FTTH is picking up, with 2012 the best year in the US since the recession hit in 2008.This growth – the industry’s best showing since 2008 – occurred as stim-ulus projects advanced in the United States and as the leading Canadian telcos ramped up their FTTH construction.However, the bad news is only 1.5 million new customers were connected with fiber. At that rate, it will take almost untill the next century to get FTTH to everybody in America.
Financing FTTH builds in today’s financial environment is challenging. The ability of deployers to sell stock to finance FTTH is zero. The bond market is uncertain. Stimulus funds have been exhausted. Among the entities that have access to financing in this environment are municipalities that can mortgage their water or electrical plant and multiple- dwelling-unit (MDU) communities.
 Broadband Communities Magazine
RVA LLC’s Michael Render will report on his next survey about MDU residents and FTTH at the BroadBand Communities Summit
in Dallas, April 16 –18.

Caution: Patching and Unpatching in High Power Equipment
An interesting exchange occurred recently on LinkedIn regarding damage to fiber optic connectors used in DWDM systems with fiber amplifiers. It's something not often mentioned but could be an issue in many systems.
Q: We are facing a problem that mainly occurred when we tried to introduce a high power 21dBm EDFA in our network for 64 split in our FTTH network. The problem is that it damages connectors and patch cords very quickly. Is it recommended to swich off the equipment before patching and unpatching? We find it difficult to implement becuase once some ports of the EDFA are used, there are running customers on those ports and we cannot power OFF the equipment again and again. Is there any other solution to safely patch and unpatch ot equipments with such high powers or we have to switch it OFF anyway?
A: I was one of the first in the USA to be trained ( in early 1990s) on EDFA OP-AMPs. You must turn-off the TX (laser/amp) prior to disconnecting the connector. If you do not you will hear a "snap" when disconnecting the connector. This is the laser reflecting back and forth between connector faces. The core of the fiber will melt down burning the core black. ( check with the equipment off and with a microscope) You will see a black tunneled out core. You will have to replace the connector in the equipment as well as the jumper you disconnected. Please use all safety practices here as this can blind a person if you have active equipment while testing!
Tim DeHart
This has always been a problem with high power in fiber networks as the core of the fiber is so small the power density is extremely high. The light out of the fiber is high enough to be harmful to eyes too! Turn the system off before patching!
Confusing Terms: Macro- Or Micro-Bending?
Two of the more confusing terms used in fiber optics are macrobending and microbending. Most of the technical definitions we have read in researching this topic don't make a clear distinction between the two. The best explanation I found was this Corning paper by John Jay where we found this graph:
Corning makes the distinction here at about 2mm bend radius, but it's more subtle than that.
Here is what OFS says in a paper about bend-insensitive fibers: "What’s the difference between macrobending and microbending? Bends fall into two categories: macrobends are bends that are large enough to be seen by the human eye, and microbends are microscopic deviations along the fiber axis. An example of a macrobend is the routing of a jumper in a patch panel; a microbend could be caused if the fiber coating squeezes a fiber as it contracts at very low temperatures. Both types of bends can result in increased attenuation that can degrade system performance."
Macrobend loss refers to losses induced in bends around mandrels (or corners in installations), generally more at the cable level or for fibers, the bends necessary to fit fibers inside splice closures or patch panels. To illustrate this, macrobending testing is done by wrapping the fiber or cable around a mandrel of a specified diameter.
Microbend loss refers to small scale "bends" in the fiber, often from pressure exerted on the fiber itself as when it is cabled and the other elements in the cable press on it. There is no real "test" for microbending. There have been attempts, for example sandwiching fibers between sandpaper or wire mesh or kinking it over a small pin, but the results have not been adequately reproducible, so no standard test exists for microbending.
Where does bend-insensitive fiber fit in this discussion? It was intended to reduce macrobending loss so cables could be run around corners better and fibers would not have as much loss when stuffed into small spaces. But microbending loss, according to technical papers we read, is helped also be careful attention to the fiber primary coating (or coatings, if applied in several layers) which protects the fiber from being bent in the first place.
It's easy to see why these two terms are so confusing! Both are similar and the differences are not so easily defined.
For Sale or Lease: 3400 Miles of Fiber
Iowa Communications Network’s governing body, the Iowa Telecommunications and Technology Commission (ITTC), released the requirements for potential bidders interested in buying or leasing the State’s state-wide fiber optic Network. The ICN backbone includes an estimated 3,400 miles of state-own fiber and 5,261 miles of leased fiber connections. The State only has authority to sell or lease the state-owned portion of the fiber Network; the leased miles are owned by private telecommunications providers. To comply with the current timeframe, interested bidders will have until April 30 to submit proposals for the Network.
Created 20 years ago for distance learning, no one could envision how critical the state-wide fiber optic Network backbone would be today. The video service is only a small part of what the Iowa Communications Network (ICN) has become. ICN provides Internet and data bandwidth to schools, hospitals, public safety, state/federal government entities, and for the statewide 911 system at levels that in many cases would not be available if the Network backbone did not exist.
Legislation passed during the 2011 legislative session required the ITTC to implement a request for proposals (RFP) process for the sale or lease of the ICN.

Single Fiber Endoscope Offers Best Resolution
FOA focuses on communications fiber optics mainly, but we sometimes look at other applications like sensors, art and visual inspection tools - endoscopes.
Recently Futurity, the university research newsletter, had an interesting article about a new endoscope design by Joseph Kahn, professor of electrical engineering at the Stanford School of Engineering. Kahn is best known for his work in fiberoptic communications.
Light is very good at conveying complex information through multimode fibers—whether computer data or images—but it gets scrambled potentially beyond recognition along the way. Kahn devised a way to undo the scrambling of information by using a miniature liquid crystal display called a spatial light modulator. To make this possible, Kahn and his graduate student Reza Nasiri Mahalati developed an adaptive algorithm—a specialized computer program—by which the spatial light modulator learned how to unscramble the light. Several years before, Kahn had set world records for transmission speeds using a similar trick to unscramble computer data transmitted through multimode fibers.
When you look at the block diagram, it looks much more like a test setup than an endoscope. But the way it works is to modulate (scan) the light coming out of the fiber that illuminates the viewing area using the modes in multimode fiber, then measure the power reflected back up the fiber, then process it to reconstruct the image. You can read the details in the technical paper.

OLANs - Resources
Over the last couple of years, we've written a lot about all-optical LANs, either based on FTTH passive optical network (PON) or point-to-point (P2P) Ethernet architecture. The more we see of these types of networks, the more we appreciate their design and economy. But how about scale - how big can they get?
In November, we ran a picture story about the new San Diego Central Library which is using a Tellabs optical LAN using PON technology that was using about 1000 4 port drops. Now we hear another Tellabs customer has over 16,000 users. That must make it one of the biggest LANs in the world.
Here are more sources of information on optical LANs - BTW, they need a name - let's start calling them OLANs!

More "Quickstart Guides"
In our continuing quest to help people understand how to test fiber optic cable plants and communications systems, we've created two more "QuickStart Guides to Fiber Optic Testing." They are simple, step-by-step guides on how to test fiber optic cable plants, patchcords or single cables using insertion loss or OTDR techniques and optical power from transceivers. It's as straightforward as it can get - what equipment do you need, what are the procedures for testing, options in implementing the test, measurement errors and documenting the results.
It can't get much simpler.

Three New Free Fiber U Self-Study Programs on Testing, Design and FTTx
There are two new free online self-study programs on Fiber U. Fiber Optic Network Design is for those interested in learning more about how ot design fiber optic networks or studying for the CFOS/D certification. FTTx is for those wanting to know more about fiber to the "x" - curb, home, wireless, etc. - or studying for the CFOS/H certification.
Got to Fiber U for more information.
We are considering using these self-study courses as part of online instructor-led courses using Linked-In. We have a new LinkedIn group, "Fiber Optic Training" (see below) which will be used for this. Join now for these courses.
- Reference Books for FOA Certifications are now available on Kindle and iPad/iPhone
  
We have created three new FOA books to be used in training for FOA certifications and as reference books for contractors, installers and end users of fiber optics. These books have full curriculum support, including free curriculum materials for teaching FOA certification courses. Because we are self-publishing these books using more modern "publish on demand" technology, they are easier to keep up to date, easier to buy and much, MUCH cheaper!
All are now available in print and electronically in Kindle and Apple iBook versions. The basic fiber optic book is also available as a self-study program in an Apple APP for iPad/iPhone/iPod.
Details on the new book each of the new books are at the book pages linked to the photos above.
FOA iPad Apps
The FOA has just released its second APP for the iPad, a free "loss budget calculator," FOA LossCalc.
FOA LossCalc
 FOA LossCalc estimates the optical loss of a fiber optic link. This will save time for the installer of a fiber optic link needing to know whether test results are reasonable and/or make a "pass/fail" determination. It can also help the designer of a link to determine if communications equipment will operate over this link.
By choosing the type of link (singlemode or multimode) and specifying the length of the fiber and numbers of connections and splices, it will calculate the end to end loss of the link. The app has default specifications for singlemode and multimode links or the user may create custom setups with specifications appropriate for any application. http://itunes.apple.com/us/app/foa-losscalc/id476262894?mt=8&ls=1
Self -Study in Fiber Optics
 Our first app is a self-study version of the FOA Reference Guide to Fiber Optics. The FOA APP builds on the FOA basic fiber optic textbook to create an interactive learning environment that builds on the iBook electronic version of the book to add a guide to use for self-study and real-time testing that provides feedback on what you have learned and correct answers to questions answered incorrectly.
The FOA APP is priced at only $9.99, same as the iBook, so the self-study program is free. Download it from the Apple APP Store with your iPad or iTunes.

NECA/FOA 301 Installation Updated
Standards cover components and systems and how to test them, but rarely get into installation issues. The FOA NECA 301 standard which covers installation of optical fiber systems has been revised for the second time, adding considerable new materials. This standard is derived from FOA educational material put in standards form and approved by ANSI as an American National Standard. It's specifically written to be used in contracts to define "installation in a neat and workmanlike manner." The standard is available from NECA. FOA members can go here for instructions on how to download your free copy.

What's New in the FOA Online Fiber Optic Reference Guide
We have been updating the Online Reference Guide to keep up with changes in the industry and adding lots of new pages of technical information.
FTTH in MDUs (Multiple Dwelling Units)
When we talk about FTTH, we often assume we are installing the fiber to a “home” where it terminates in a optical line terminal (OLT) and services (voice, data and video) are delivered inside the subscriber’s "home." But since we may have detached single-family homes, row houses or living units in a large building, the situations can be quite different, requiring different architectures and installation practices. To clarify the options for fiber in MDUs, FOA has created a new page in our FTTx section of the FOA Guide to explain the options.
FOA Guide: FTTH in MDUs
Three new "Quickstart Guides" for fiber optic testing: cable plant & patchcord loss, power and OTDR
OLANs: Optical LANs - based on FTTH technology and offering speed and economy for most premises applications.
FTTx and Design Pages Updated
As we developed the new Fiber U self-study courses, we updated the FTTx and Design pages and added a FTTx installation section.
Testing FTTH
Basic guidelines for testing FTTH PON networks
Learn More About OTDRs - Download a Free OTDR Simulator
More and more installers are being asked for OTDR testing but using these instruments is not easy. They are hard to set up properly and complicated to interpret the traces. Using the autotest function can lead to disastrous results! The FOA has a good tutorial on OTDRs on our Online Reference Guide and we added a free download of an OTDR simulator to the OTDR section so you can learn how to use an OTDR on your PC.
More New Info:
Links to manufacturers and distributors of fiber optic lighting products.
The FOA Online Fiber Optic Reference Guide has become very popular - perhaps the most popular technical website ever, typically with over 360,000 users downloading about 1.75 million pages in 2011! We continue updating materials regularly, keeping it as up to date as possible.
Find What You Want Using "Google Custom Search
 There's so much information on the FOA Tech Topics and Online Fiber Optic Reference Guide that even a well-organized Table of Contents isn't enough and when the material is always changing, an index is impossible to maintain. So the FOA is using the latest technology in search, Google Custom Search, which will allow you to search just the FOA Tech Topics and Online Fiber Optic Reference Guide for any topic you want to find more about.

School News
Quote from one of our certified instructors: I want to thank you and your organization for all the resources you provide for the students and the opportunity to offer the certification to the students. The fact that you published the book yourself to get the cost down and the unlimited free resources on your website shows a commitment to the public that is second to none. I let it be known to the students that the FOA is the best in the industry at supplying knowledge and resources related to the communication industry. I look forward to passing on the information that you provide for the industry.
New Schools
The FOA welcomes the newest additions to our listing of FOA-Approved Training Organizations:
#332- Knowlogy Corp.
#645 - Iowa Electrical State Training Center (JATC)
Find a listing of all the FOA-Approved schools here.
It's Now A Lot Easier To Find A FOA-Approved Training Organization
Most phone calls we get regarding finding a FOA-Approved training organization want to know two things: what school is closest to me or what school offers the certifications I need. That can be difficult, since the FOA has almost 200 training organizations we have approved worldwide!
We've been looking at ways to make it easier, and we think we've got a good solution. In fact we have two solutions.
First we have added a sortable table of all the FOA-Approved schools.
You can also use our FOA Google Map Application to find FOA-Approved schools.
Here are links to the sortable table of all the FOA-Approved schools and FOA Google Map.
What Should A Fiber Optics or Cabling Tech Know and What Skills Do They Need?
The FOA has been updating its lists of KSAs (Knowledge, Skills, Abilities) for fiber and cabling techs. The updated list is now on the website for your information and comments - as fiber and cabling KSAs evolve as new technologies develop.
KSAs for fiber and cabling techs.
Good Question! Tech Questions/Comments Worth Repeating
Tech Hint: Did You Know You Have A Fiber Optic Tester In Your Pocket?
Yes! That old mobile phone has a camera which may be sensitive to infrared light - lots more than your eye - and can detect light in an optical fiber or from a transmitter. Chris Hillyer,CFOT/CFOS/I, Master Instructor, Northern California Sound & Communication JATC sent us some photos showing how this works. See below or the video now on YouTube. Update: You should check out your old cell phones before you recycle them. We've found older models use sensors which are better at infrared than the newer ones which take better pictures. This is a good use for your old cell phones hiding in the drawer!
Using A System Source For Testing Loss
Q: Can an SFP optical transceiver be used in place of a light source to test link attenuation?
A: Certainly a system source can be used to test attenuation. You just need a means to turn it on and have it stay on for the duration of the test. Attach a launch cable or patchcord to it, measure the output of that patchcord with a power meter and use as the "0 dB" reference. Connect it to the cable plant, attach a patchcord to the other end and measure the power output - the same output that would be coupled to the receiver. The difference in the two power levels is the loss. In fact, you measure the actual loss the cable plant will see in operation.
The method is similar to this: http://www.thefoa.org/tech/ref/testing/test/OFSTP-14.html
About the only time we would not recommend this is a DWDM system or AM CATV ssytem with a high power laser and/or fiber amplifier as the power levels are high enough to be dangerous, to the connectors as well as the equipment and test personnel!
OTDR Readout (3/13)
Q: If I set my OTDR to measure distance in kilofeet or miles, does the OTDR still display fiber attenuation in dB/km?
A: Yes, it seems most OTDRs will report the fiber attenuation coefficient in dB/km even when you measure distance in other units.
Microtrenching (3/13)
Q: I’m hoping someone can point me in the direction of a technical paper on micro trenching.
A: We've covered the topic many times in our newsletters and online Guide. I used our site's Google Custom Search and found some references:
10/11 - The Fiber Optic Association Newsletter
6/12 - The Fiber Optic Association Newsletter
OSP fiber installation - The FOA Guide
In this newsletter http://www.thefoa.org/foanl-08-12.html we have links to a company called "Nano-Trench" http://www.nano-trench.com/en/homepage.html
Google actually ran a contest on it - probably preparing for their KC installation: Micro-trenching at Google - YouTube
Number of Modes (2/13)
Q: How many modes can travel down a multimode fiber at the same time.
A: It's something one can calculate based on the core index profile, diameter and wavelength of the light.
A typical multimode fiber at 850nm carries hundreds of modes, a single mode fiber at 1310nm carries one.
Here is a very technical article:http://www.rp-photonics.com/multimode_fibers.html
But you can see the effects in two FOA YouTube videos.
FOA Lecture 21: Visual Fault Locator Demonstration shows the extra modes transmitted in singlemode fiber when transmitting 650nm red light below the singlemode cutoff
FOA Lecture 22: Mode Power Distribution in Multimode Fibers Demonstration shows many modes in multimode fiber using the same 650nm laser. At higher wavelengths like 850nm, there are many more modes than shown here.
Jim
Cable Colors (1/13)
Q: We have a customer building a Data Center. The customer will be using OM3 Fiber optic for backbone an there will be 2 diverse paths. Now the customer is asking to provide 2 different colors of OM3 cable and same 2 colors of patch cord on OM3. Is it correct to use different colored cables other than the standard aqua for OM3 fiber?
A: Yes, it is OK to use different colors of cables to identify cables in diverse paths. The "standard" color for OM3/OM4 cables, aqua, is a recommendation but it's not uncommon in large enterprise networks and data centers to see lots of different cable colors.
Flashlight Test? (1/13)
Q: We are trying to troubleshoot a fiber cable by using a flashlight pointed in one end and seeing if it comes out the other end...(I know a bit low tech but..) The distance seems to be too great to get the light of the flashlight to come through.
What tool out there can help with this issue?
A: A "flashlight test" is often used for a continuity or polarity check. The problem is getting the flashlight aligned with the fiber and coupling sufficient light to be able to see anything. For multimode fiber going short distances (a few hundred meters), a flashlight with a alignment fixture can be sued, like this http://www.afsi.us/product.php?product=CONTINUITY
For singlemode fibers you need a more powerful source that is carefully focused for the small core of the fiber, like this http://www.afsi.us/product.php?product=AF-OS405
But in reality, all installations should be tested for loss with a light source and power meter. See here for an overview: http://www.thefoa.org/tech/ref/basic/test.html
Online Discussions (12/12)
Q: I was wondering if the FOA might think about adding a feature to the FOA website… Like a technical discussion forum… or other member forums for discussion.
A: We use LinkedIn for those kinds of technical conversations. We have a CFOT group and a Fiber Optic Training group that are pretty active. Anyone can join the FOA Fiber Optic Training Group or join the FOA Group if you are a CFOT.
MM to SM Adapter (12/12)
Q: Is there a coupler on the market to hybrid SM and MM to avoid high dB loss in that even?
A: No! Several people have tried to make tapered fibers to mate different fiber sizes but none successfully. You need electronics to do it.
Matching MM Fiber For Launch/Receive Reference Cables (12/12)
Q: These days fiber cable is not simply 62.5um or 50um - we now have 3 different grades of 50um fiber......ie. OM2, OM3, OM4. How important for cables to be matched for this?
A: The difference between OM2/3/4 fiber is the structure of the core used to increase the bandwidth. Since all these fibers are designed to have the same core diameter and NA, doing insertion loss tests with mixed types is not a problem. However, many of these laser-optimized fibers are not made as "bend-insensitive fibers and mixing those fibers with regular fibers can be a problem.
Testing Cables With Expanded-Beam Connectors (12/12)
Q. How do I test cables with expanded-beam connectors?
A. Since most meters have smaller detectors they may not capture all the light from these connectors, so a 3-cable reference with a known good cable of the type under test is probably the best method to use. See here and here in the FOA Guide.
Removing Obsolete (And Valuable) Copper Telephone Cables (11/12)
Q: In our FTTH build-out we have changed a large number of customers from copper to fiber. There is a huge amount of copper underground lying free. (Inside ducts) The issue is that in the access network most are together with new fiber cables (no sub-ducts). In the primary routes there are large count copper, say 2000 pairs and above too. So pulling out wont be easy and need to be done by a specialized party. There is a large amount of money down below! I hope you can give me some guidance and refer me to the right company or the right person to get an idea.
A: Yes at the current price of copper this is indeed a very profitable "mining" venture! A web search for "removing copper cables from underground ducts" gives lots of leads, but the company I remember talking to is "Cable-X" http://cable-x.net/what-is.htm which is based in the Netherlands.
Would FTTO Work? (11/12)
Q: We have a project we are working on and I had a few questions: The project is a large indoor mall. The mall wants to add public WiFi. Would FTTO work for this application?
A: This is an ideal application for FTTO. You would use singlemode fiber and would need to add power at the antenna locations for the wireless access point and a media converter or switch. One advantage is flexibility of placement of APs in a large facility with direct connections to just one equipment room. I would look at prefab cable assemblies too- you might be able to avoid field termination or splicing.
Mode Conditioning Patch Cables (11/12)
Q: Something new came up in a discussion with a network engineer. He told me about “mode conditioning patch cables”. What are they?
A: They were originally used for Gigabit Ethernet at 1300 nm using laser sources. 1000Base-LX sources were lasers with singlemode pigtails. Multimode fibers of the era were notorious for having incomplete fusion of the glass in the center of the core which caused bandwidth problems. Mating a SM pigtail laser to one of these fibers caused big bandwidth problems since they launched right into the center dip. The immediate solution was to set up an offset launch to avoid the center of the fiber with LX sources. VCSELS had problems with these fibers too, even though they launched a much larger spot, so the laser-optimized 50/125 OM3 fibers were developed to not have the center dip and OM4 followed soon thereafter. 10GBASE-LX4 had the same problem, of course, only worse, with OM1/2 fibers and SM lasers. The patchcords are usually made by splicing SM to MM fibers with an offset of ~10 microns. I cannot say I know anyone who has actually used them! 1300 nm has no advantage with MM fiber as the bandwidth has been optimized for 850nm. And they are much more expensive than 850nm VCSELs. It is unlikely you need them with OM3/4 fiber and I would not recommend running 10G over OM1/2 without some field trials.
Fiber Cleaning
This is a topic we keep reminding everybody about, and here is why:
From a contrator in the Middle East: Here some samples of the connectors for SM fiber already installed in the system we were testing.
 
As you can see, the dirt is large compared to the size of the fiber (dark gray), and the core (not visible here) is only 9/125 of the overall diameter of the fiber! More on cleaning. See Product News below for links to vendors of fiber cleaning products.
See news about Fiber Optic Cleaning Videos on YouTube by ITW Chemtronics below.
Measurement Uncertainty: Everyone testing fiber optics should understand that every measurement has some uncertainty - whether you are measuring loss, length, wavelength, power, etc. Knowing that uncertainty is very important to interpreting the measurement. It's worthwhile to read and understand the issue of measurement accuracy covered in this page of the FOA Online Fiber Optic Reference Guide.

Benchmarking Fusion Splicing And Selecting Singlemode Fiber
We've been asked many times "How long does it take to splice a cable?" It's not a simple answer as it varies with the number of fibers in the cable and the work setup, including whether one or two techs are working at a job site. FOA Master Instructor Joe Botha of Triple Play in South Africa did his own analysis based on decades of experience both splicing cables and teaching others how to do it properly. This is one of the best analyses we have seen because Joe includes prep times as well as splicing times and differentiates between one tech and two techs working together. He adds some other tips on fusion splicing too. This should be mandatory reading for every tech and given to every student! Here is Joe's splicing analysis.
Joe also has an excellent writeup on how to choose singlemode fiber that helps understanding the different types of G.6xx fiber. Read it here.
And you will want to read Joe's report on splicing different types of SM fiber, including bend-insensitive (G.657) fiber. Read it here.

A Fiber Optic Tester In Your Pocket? (See the video on )
Yes! The camera in your cell phone is sensitive to infrared light - lots more than your eye - and can detect light in an optical fiber or from a transmitter. Chris Hillyer,CFOT/CFOS/I, Master Instructor, Northern California Sound & Communication JATC brought this to our attention.
 
If you have an old cell phone, try it too. Our experience is that older cell phone cameras have better sensitivity at IR wavelengths than newer phones, so you may want to toss that old phone into the toolbox.

Helping Solve The Patch Cord Problem
Patch panels are often a mess, with cables running in all directions causing - at least after some moves, adds and changes - a big mess. TE Connectivity (AMP to us old-timers) is now offering a new 1.2mm cable design for patchcords that can help reduce the mess.
The 1.2mm patch cord requires half the physical space needed for small form factor 1.6-mm patchcords, one-third of the space needed for commonly-used 2.0-mm patchcords, and is up to 3 times the strength of these larger diameter cables. Available with singlemode SC and LC connectors, the 1.2mm cable enables higher equipment densities in smaller space, while reducing capital and operating expenditures.
Compare the size of the cable to the size of the LC connector above. It's hardly larger than typical 900 micron tight buffer fiber!
One reason this cable is possible is the use of bend-insensitive fiber - reduced bend radius fiber as TEC calls it. We're seeing more BI fiber in premises applications because it allows smaller, more rugged cables that are easier to install.
Bend Insensitive Fibers Get Smaller Coatings, Smaller Cables
OFS has started supplying BI-SMF with a 200 micron coating instead of 250 microns. This means they can make smaller cables or higher density cables, ideal for FTTH and OLANs. Like the TEC cables above, smaller cables are easier to handle, especially in high density environments.

Cleerline "Non-Strip" Fiber Strips With Fingernails, Not Tools (12/12)
Cleerline Technology Group, an offshoot of D’Addario & Company, Inc. (yes, the people who make guitar strings, among other things), is offering a new type of fiber. They have a proprietary, patented coating technology that allows the tech to strip off the buffer coating with a fingernail when connectorizing in the field.
Watch their YouTube Video to see how it works.
Illuminated Fishtape: Why Didn't I Think Of That?
Klein Tools, (http://www.kleintools.com/) for professionals since 1857, introduces a new illuminated fish rod tip (Cat. No. 56119). The bright white, omni-directional light illuminates when fishing above ceilings, in attics, through walls, in crawl spaces and under raised floors. The hook or bullet nose attachments (sold separately) fit smoothly into the threaded top and the ends are tapered for easier pushing and pulling.
Handheld OTDR
Advanced Fiber Solutions has introduced a new compact portable OTDR that offers high resolution (to 1m) and light weight (1.6 pounds, 0.72 kg) plus numerous wavelength and range options. Here is more information.
Micro-Trenching, Cable Removal
Nano-Trench offers products for micro (or I guess they call it nano-) trenching and their website is very informative. They also have Kabel-X, a method of extracting copper cables from old conduit. Both websites are informative and interesting. Watch this video on the cable removal process!
Protecting Pedestals From Rodents
Pedestals and underground vaults can be damaged by rodents who come up through the base and damage cables. Uraseal "Drain N'Seal" foam deters mice from taking up residence in your pedestals. They have some good videos on using their product.

- FTTH Notes:
FTTH in MDUs (Multiple Dwelling Units)
When we talk about FTTH, we often assume we are installing the fiber to a “home” where it terminates in a optical line terminal (OLT) and services (voice, data and video) are delivered inside the subscriber’s "home." But since we may have detached single-family homes, row houses or living units in a large building, the situations can be quite different, requiring different architectures and installation practices. To clarify the options for fiber in MDUs, FOA has created a new page in our FTTx section of the FOA Guide to explain the options.

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.
