FOA Publishes New Textbook On Outside Plant Fiber Optics
FOA Reference Guide to Outside Plant Fiber Optics
The FOA has published a new textbook on outside plant fiber optics, the FOA Reference Guide to Fiber Optics. This textbook is designed to be used for training outside plant fiber optic technicians, studying for FOA certification and as a reference guide for anyone interested in outside plant fiber optics. The book is available from the FOA eStore or Amazon.com for only $27.95 and will soon be available on the Apple iPad and Amazon Kindle electronic book reader.
Outside plant (OSP) fiber optics covers a giant topic, including applications like telephone and wireless backhaul, CATV, municipal networks, utility “smart grid” and the like. The book covers all types of OSP installations including underground, buried, aerial and submarine along with the specialized components, installation techniques and testing requirements for these applications.
This new FOA textbook is the third in a series of reference guides from the FOA covering basic fiber optics, premises cabling (fiber, copper and wireless) and now outside plant fiber optic cabling. This textbook was developed from new material on the FOA Online Reference Guide website (www.foaguide.org), the largest and most widely used reference site about fiber optics on the Internet. For those who prefer reading printed material, we offer this new book, a basic reference for fiber optics and a study guide for FOA certifications. Supplementary materials with even more depth on many subjects, are, of course, on the FOA Reference Guide website.
The FOA has always tried to provide the world with sources of technically correct, unbiased information on fiber optics using both print and electronic media. With the FOA’s experience in certifying over 30,000 fiber optic techs in the last 15 years, we have included the most up-to-date information and organized the materials to make them better arranged for training.
The FOA Reference Guide to Outside Plant Fiber Optics will be used as the new reference guide for training students for the FOA Certified Outside Plant Fiber Optic Technician (CFospT) certification.
The FOA Reference Guide to Fiber Optics, ISBN: 1450559670, is available at the FOA eStore (https://www.createspace.com/3429177) or Amazon.com for $27.95.
30,000 CFOT®s and Counting!
During June, 2010, the FOA certified its 30,000th CFOT®. Since its beginning in 1995, the FOA has grown rapidly, and with the accelerating pace of fiber optic applications - driven by other technologies like wireless, security, passive optical LANs, and data centers - has created more demand for well-trained and certified fiber optic technicians. The FOA is now growing at a rate of about 15% per year, astounding in the current world economic turmoil, but indicative of the importance of fiber optics to communications in todays world.
FOA salutes all 30,000 of our CFOTs and holders of other FOA certifications and the hundreds of FOA-Approved schools that have trained the majority of them.
OFSTP-14 is DEAD! Long Live OFSTP-14!
OFSTP-14 is, of course, the TIA standard for testing installed multimode fiber optic cable plants which has been around more than 20 years and is the one TIA standard probably most familiar to contractors and installers. It has been due for updating, but TIA has been replacing many US-written standards with the equivalent international documents.
The TIA has adopted IEC 61280-4-1 as the replacement of OFSTP-14. Most of the two documents is the same, with some important exceptions.
$800 million More For Broadband Stimulus Programs in US
U.S. President Barack Obama announced on Friday nearly $800 million in loans and grants for the build-out of broadband networks to reach homes, schools and hospitals. The grants and loans, which will be matched by another $200 million in private investment, is part of Obama's roughly $800 billion federal stimulus package, which includes $7.2 billion for broadband expansion projects. The 66 new infrastructure projects will directly create 5,000 jobs and help spur economic development in some of the nation's hardest-hit communities.
The departments of Agriculture and Commerce are administering a total of $7.2 billion in grants and loans for projects in 50 states and Washington, D.C. Read more - Reuters.
Fiber Optics In State-of-the-Art Science/Art Center Installation
The Leonardo, Utah’s science-tech-art center, has selected an artistic collaborative to create a major public art installation in the building, which will open to the public April, 2011. Brian Brush and Yong Ju Lee, both of New York City, will create an installation, called the “Dynamic Performance of Nature,” that will be both an artistic and architectural feature on The Leonardo’s main floor. The FOA was pleased to provide some technical assistance and sample fibers in the design of the project.
The installation will be constructed of custom-milled, recycled-plastic panels arranged in a wave pattern, such as that of light or sound. Fiberoptic cables hang between the panels and are attached to solar-powered LED lighting array, which changes color, intensity, and flashing duration based on a connection to environmental sensors that measure data from activities like wind, seismic or solar activity, precipitation, and visitor movements.

What is a "Fiber Optic Network"? And who has the right to decide that?
We reported in the last FOA Newsletter that the National Advertising Division (NAD) of the Better Business Bureau (BBB) has told Time Warner Cable and Cox Communications that they should not use the term "Fiber Optic Network" in their advertising, responding to a complaint about their advertising from Verizon.
You can read the complete NAD comments on Time Warner Cable and Cox Communications at these links.
The Fiber Optic Association, Inc. send a response to NAD saying we think the NAD decision is misguided. Time Warner is appealing NADs decision, so there is still time to comment.
The FOA sent a letter to NAD expressing our opinions. If you want to comment also, here is the NAD website: http://www.nadreview.org/ContactUs.aspx Address your comments to C. Lee Peeler, President.

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.
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!
Details on the new book each of the new books are at the book pages linked to the photos above.
FOA Online Fiber Optic Reference Guide
The FOA Online Fiber Optic Reference Guide has become very popular - perhaps the most popular technical website ever, typically with over 30,000 users monthly! We continue updating materials regularly, keeping it as up to date as possible.
Just this month, we added a page on "polarity" for fiber optic networks. Although it seems obvious that connecting transmitters to receivers is required, how it's accomplished can be confusing! We already updated the Premises Cabling sections in conjunction with publishing the FOA Premises Textbook and are now focused on outside plant applications (OSP.) We've already added a new page on chromatic dispersion (CD) and polarization-mode dispersion (PMD). Next we're working on cables for OSP applications and splicing.

Mississaug Training Consultants
Mississauga, Ontario, Canada
At 1:30pm, June 23rd, things were looking up. The 12 person Installation and splicing class was on the 6th floor of the Monte Carlo Hotel in Mississauga, Canada. They were in the midst of doing the five day CFOT® course to become certified installers through the Fiber Optic Association. As I watched the students polish their connectors I noticed the tables starting to sway. Sure enough as we, and the building, swayed with a 5.5 earthquake the students polished on completing their connectors and with extremely low loss.
Taking the fiber optic Installers certification course in itself was a positive achivement but fearlessly polishing the connectors during an earthquake....hey that was something else. Further, these students complete the FOA Training program with a high degree of proficiency in splicing and polishing connectors, including APC, SM connectors with a reflection of -70 db and at least equal to or better than the best factory products. Our class learns by doing that pigtails are not needed and they quickly find that the can add furcation tubing to the fiber and install a connector at least to industry standards and save the cost of a splice tray, fiber manager and the additional splice loss.

Good Question! Tech Questions Worth Repeating
Fiber Optic Polarity
Q: This summer a fiber ring is being installed on our campus. It will be terminated in a 24 port fiber patch panel in each buiding. Does the industry standard provide that if I attach fibers 1 & 2 to my servers and fibers 1 & 2 to the network in each other building that they will be able to communicate? Or is it far more complicated than that?
A: Since most fiber optic links use two fibers transmitting in opposite directions to create a full duplex link, you need to ensure that transmitters are connected to receivers and vice versa. Traditionally, fiber links are made where pairs of fibers are crossed between patch panels so fiber 1 at one patch panel will be connected to fiber 2 at the patch panel on the other end, fibers 3/4. 5/6. etc. are handled likewise. Thus, when connecting patchcords, fiber 1 (or the odd numbered fibers) can always go to the transmitter and fiber 2 (or even numbered fibers) goes to a receiver and proper connectivity is maintained.
This is described in TIA-568 as polarity.
Obviously, nothing substitutes from proper markings and documentation of the cable plant, a task that is often given little consideration until the network equipment installers are forced to use a visual fiber tracer to find which fibers to connect.
If possible, discuss this with the fiber installers to ensure you are on the same wavelength (pun intneded.)
BTW, the FOA has a good Tech Bulletin and web page for network users:
Choosing, installing and using fiber optic products for communications network users
and User's Guide To Fiber Optics
Just this month, we added a page on "polarity" for fiber optic networks to the FOA Online Reference Guide.
Nothing is more confusing that jargon. Here is a Q&A on jargon:
Q: One thing I did notice, you teach that there are three types of UTP cable tests, wire map, certified and verified here; http://www.thefoa.org/tech/ref/premises/test.html.
There is the danger that trained individuals will confuse cable testers called" verifiers" and "certifiers" for cable that is printed "verified". UL's definition of verified is individual critical attributes testing and NOT BERT testing, which is just the opposite of a "verification" BERT tester. The "certifying" tester is more apt to "verify" a cable, permanent link, or channel. I know this seem minor but it isn't. There has to be a clear distinction as to what the customer wants, BERT verses attribute tests. And the use of conflicting terms between cable and hand-held testers is unfortunate.
A: You're right about UL. Not only do they use "verified," but they use "certified" as well - I remember when it was just "listed." (http://www.ul.com/global/eng/pages/offerings/industries/wireandcable/faq/)
I believe that Ron Vogel of Test-Um was the initiator of the "verification" term when he dropped a GBE chip into a tester and started selling it at a fraction of the cost of a UTP cable "certifier," although I've actually never seen the term "verified" used for cable tested with one of his testers. Fluke, of course sells a cable "verifier" too (http://www.flukenetworks.com/fnet/en-us/products/MicroScanner%202/Overview) so that means it's made it to the industry jargon.
A quick search shows 3030 references to the term "verification" and 2850 for "verified" on the UL website! UL is even ambiguous about their use of the term; see what they say:
"What does the term "verified" mean?
The term "verified," when used in a UL marking, means that the product has been tested and complies with one or more specific requirement. These requirements may be safety- or performance-related. In the UL system, the words "Classified" and "verified" mean the same thing. For a complete explanation of "Listed," "Classified" and "Recognized," read more on the UL Mark."
Reminds me of a panel at ComNet with Bob Metcalfe, co-inventor of Ethernet, who said "Standards are such wonderful things because we have so many to choose from."
Q: I bid a job today with 50 um aqua OM3 MM. Any special characteristics as far as fusion splicing and testing? I know I will have to get some LC jumpers of 50 um size.
A: No problems should be expected. If you're splicing it, check the fusion splicer programs (and maybe the fiber manufacturer) to see if special setup parameters are needed. And you will probably need hybrid jumpers with LCs to the connectors on your test equipment.
Q: We're having a fiber network installed. We know that two fibers are used for each link, but how do you ensure transmitters are always connected to receivers? Where do you make the crossover in the fibers?
A: While there are several ways to do this, it's less complicated to do it in the fixed cabling, not the patchcords. Here is an explanation of fiber optic link polarity on the FOA Online Reference website.
Connector or "Connection" Loss?
Q: Isn’t the loss in the standard for a connector pair and not a single connector?
A: Yes, it is. All connector losses are for a mated pair. We've been trying for years to say "connection loss" instead of "connector loss" but most everybody still says "connector loss" and we fall back into that often ourselves.
Here's what is in the FOA online reference guide at http://www.thefoa.org/tech/ref/basic/term.html :
"Connector and Splice Loss
The primary specification for connectors or splices is loss or the amount of light lost in the connection.
When we say connector loss, we really mean "connection" loss - the loss of a mated pair of connectors, expressed in "dB." Thus, testing connectors requires mating them to reference connectors which must be high quality connectors themselves to not adversely affect the measured loss when mated to an unknown connector. This is an important point often not fully explained. In order to measure the loss of the connectors you must mate them to a similar, known good, connector. When a connector being tested is mated to several different connectors, it may have different losses, because those losses are dependent on the reference connector it is mated to."
We were discussing this recently with another person who has a spec which calls for a loss for the mating adapter! We had to help him explain to the spec writer that each connector and the mating adapter contribute to the loss but one cannot apportion the loss to each component separately!
Low Water Peak Fibers
Q: One of the issues on which vendors try to differentiate themselves is "zero" and "reduced" water peak fiber. Is there anything in Fiber U or the FOA that addresses this?
A: Low water peak fiber is done to allow coarse WDM. It's very expensive to do and not very worthwhile unless you want to do CWDM. See http://www.thefoa.org/tech/ref/testing/test/CD_PMD.html for details.
Q: Why do we see a “gain” in some OTDR measurements? How can there be a gain?
A: Gainers are caused by differences in the backscatter coefficient of the fibers being spliced. Not only does that cause gainers, but in the opposite direction it causes the loss to be shown as greater than it actually is and it affects the measurement accuracy of any loss measurement with an OTDR. We have a tutorial on OTDRs that covers what we call "gainers" on the FOA Online Reference Guide: http://www.thefoa.org/tech/ref/testing/OTDR/OTDR.html
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! See Product News below for links to vendors of fiber cleaning products.
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.
Fiber Optic Safety Poster
We've had numerous requests to reprint our guidelines on safety when working with fiber optics, so we have created a "Safety Poster" for you to print and post in your classroom, worksite, etc. We suggest giving a copy to every student and installer.

Yes, An OTDR-Type Instrument Can Resolve Short Lengths - with mm Resolution
Luna Technologies offers a OFDR - optical frequency domain reflectometer that can resolve about 3 mm (1/8 inch) out to 500 meters. OFDRs work in the frequency domain, not timing a return signal, to get ultra high resolution over a limited distance range with considerably less dB resolution than a OTDR, 0.1 dB in this instrument. The primary use for this instrument is testing cable harnesses such as those used on aircraft, as it can pinpoint problems with connectors or bending loss. Read more.
Bend-Insensitive Fiber Becomes Corning's Standard 50/125 Fiber -
But it means changes in the way you test with it!
Corning announced that effective April 1, 2010, ClearCurve® multimode optical fiber will become its standard 50-micron multimode fiber product offering. "ClearCurve multimode fiber is the world’s first laser-optimized, high-bandwidth, multimode fiber to withstand tight bends at 7.5 mm radius with substantially less signal loss than traditional multimode fibers. ClearCurve multimode optical fiber was first introduced by Corning in Jan. 2009 and has been validated through broad customer acceptance of the product.
Traditionally, when an optical cable experiences tight bends, some of the light can escape from the fiber core and part of the signal can be lost. Corning ClearCurve multimode fiber is designed to keep the light in the fiber core, even under tight bends, and better maintain the integrity of the optical fiber signal.
“Corning’s 50-micron multimode fiber customers will now benefit from superior bend performance. This will result in faster and more efficient optical cable routing and installation, and significantly higher spare operating margin, at no additional cost,” said Martin J. Curran, senior vice president and general manager, Corning Optical Fiber.
Corning ClearCurve multimode fiber meets or exceeds the OM2, OM3 and OM4 industry standards for high-bandwidth, laser-optimized multimode fiber. Corning will demonstrate the performance of ClearCurve multimode optical fiber from March 23-25, 2010, at OFC/NFOEC in San Diego. Detailed product specifications are available at www.corning.com/clearcurve."
When You Test...
Most standards call for a "mandrel wrap" mode conditioner on your launch cable. The Corning announcement made us wonder what happens with this bend-insensitive fiber if you wrap it around a standard mandrel - it should not act the same as regular 50/125 fiber. We contacted our friend the Marketing Manager for the product at Corning and he confirmed our suspicions. The difference in the bend sensitivity of the fiber requires a much smaller mandrel, only 6 mm in diameter, to have the same effect.
This is detailed in Corning Application Engineering Note "Multimode Fiber Considerations for Test Jumpers, AEN 131, Revision 2" available from Corning.

According to a just released FTTH Council Report prepared by RVA, FTTH connections continue to grow in North America - 99% of which are in the US, but growth seems to be slowing, probably a consequence of the current economy. Much of the FTTH deployment in the US has been due to Verizon's $23 billion investment in FTTH, but the report noted that FTTH is now being deployed by more than 750 service providers across North America. Most of these service providers are small, independent telephone companies that are replacing their copper lines with end-to-end fiber to ensure their future competitiveness as broadband providers. Of the service providers not yet offering FTTH, a majority say they are likely to soon. You can download and read the entire report from the FTTH council website. http://www.ftthcouncil.org/sites/default/files/RVA.FTTH_.Apr10.040712Final.pdf

Verizon To Complete FiOS System in 2010, Looks for 40% FiOS penetration
This year Verizon Communications (NYSE:VZ) plans to complete the fiber-to-the-premises network it started in 2004, and it is focusing harder on customer penetration.
“We’re averaging just under 30% [FiOS penetration] for the whole property,” Verizon CEO Ivan Seidenberg told investors recently. “My people think they can get to 34%. They’re not going to get paid very much if they don’t get to 40%. The question is how quickly we can get there.” (Connected Planet)

New FOA Jobs Website
We get many questions from CFOTs, students at FOA-Approved schools and others contemplating getting into the fiber optic business regarding jobs in fiber optics - and how to find them - so we’ve created a new web page to share some information we've gathered about jobs in our industry. The information is designed to help you understand what jobs are available in fiber optics, how to find them and apply for them.
While the overall economy is pretty bad - you've probably heard that there are 5 times as many people unemployed in the US as there are jobs available, telecom is a bright spot - broadband is a major focus of stimulus spending in the US and countries around the world are building fiber networks as fast as possible. Even wireless companies have to build fiber for their backhaul. Cities are installing fiber linked surveillance cameras and smart traffic lights. Fiber is the link making Smart Grid possible. Companies like Allied Fiber are building large private networks. Telecom is one of the fastest growing businesses worldwide.
If you are looking for a job in fiber optics, here is the FOA's guide to jobs.
The FOA has created a group on expressly to help our CFOTs find employment and contracting opportunities. If you are a CFOT and are interested in participating, join us on . If you have job openings, let us post them on .
