|FOA Online Fiber Optic Reference Is Continually Expanding
And Adds "Google Custom Search"
The FOA Online Fiber Optic Reference Guide is now available for use. It's not complete - we expect it to never be "complete" but always expanding! We want you to contribute and give us feedback on how we can make it better!
The new FOA Online Fiber Optic Reference website continues to grow. We're not just adding technical materials, but study guides to help you use it. This month, we added a section on premises cabling (fiber, copper and wireless) and study guides for CFOT students, CFOTs wanting a refresher and anyone just wanting to learn about fiber optics. We also added a Instructor's Guide to assist teachers in understanding how the website relates to our textbooks and can be used in conjuction with or in place of textbooks and other references in class.
Wanted: Links To Technical Materials
Next, we're soliciting links from fiber optic manufacturers and other organizations that have created technical materials that would be of interest to our readers. If you have technical websites you want to share, go here for our guidelines for submission.
FOA Adds "Google Custom Search to Tech Topics and Online Fiber Optic Reference Guide
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. Try it!
FOA Online Fiber Optic Reference Guide "Tour"
Each month, we'll do a quick tour of part of the FOA Online Fiber Optic Reference to show you what's there and how to use it effectively. This month we'll talk about our study guides. We've created three of them: one for students preparing for the CFOT exam, one for CFOTs wanting to refresh their knowledge and one for anyone wanting to learn about fiber optics. Each of these guides your through a course of study to gain knowledge on the basics of fiber optics, but aimed at three different goals. For students, it's preparing for the CFOT exam, for CFOTs, it's keeping up with technology or finding some piece of information that needs clarification, and for anyone wanting to learn about fiber optics, it guides them through the basics in an organized way to help them learn on their own.

Good Question! Tech Questions Worth Repeating - And - This Month - Commenting On
Q: This installation specification has a bulleted list of instructions, the first sentence reading, "Observe
minimum bend radius and cable pull tension." What number(s) should be there? Is there an average cable pull tension for all optical fiber?
A: Cable pulling specs are based on cable design and diameter. Pulling tension is rated for the cable type, typically 100-200# for indoor cable, 600#+ for outside plant. Bend radius is generally specified at 20X cable diameter under pulling tension, 10X relaxed after pulling. Under any circumstances, check with the cable manufacturer for specs on the particular cable you are using.
It was brought to our attention that a section of TIA-568-B (Structured Cabling Standard) calls for a 15Xcable diameter spec. Here is the text:
10.3.1 Minimum bend radius and maximum pulling tension
The bend radius for intrabuilding 2 and 4-fiber horizontal optical fiber cable shall not be less than 25 mm
(1 in) under no-load conditions. When under a maximum tensile load of 222 N (50 lbf), the bend radius
shall not be less than 50 mm (2 in).
The bend radius for intrabuilding optical fiber backbone cable shall not be less than that recommended
by the manufacturer. If no recommendation is known, then the applied bend radius shall not be less
than 10 times the cable outside diameter under no-load conditions and not less than 15 times the cable
outside diameter when the cable is under tensile load.
The bend radius for interbuilding optical fiber backbone cable shall not be less than that recommended
by the manufacturer. If no recommendation is provided or known, then the bend radius shall not be less
than 10 times the cable outside diameter under no-load conditions and not less than 20 times the cable
outside diameter when the cable is under a tensile load up to the rating of the cable, usually 2670 N
We do not know the reasoning behind this specification. Using 20X for all cable under tension meets the requirements of all known standards.
Q: When we do the Link - Loss - Budget calculation, do we need to consider the any loss for cable bending. For our project, the Single Mode FO cable is run in cable tray, which has at least 4 to 6 bends (90 deg turning). If bending loss to be considered for each Bend, then what are the typical values for Single Mode Fibre.
A: You should not include bending losses in link loss calculations since there should be no bends tight enough to cause loss. If the measured loss is higher than calculated loss, you should then look for bending loss with an OTDR.
We should have linked you to the Tech Topic on Link Loss Budgets: http://www.thefoa.org/tech/lossbudg.htm
Q. Is it OK to use inexpensive air-gap attenuators with lasers in singlemode networks?
A: Since lasers are sensitive to reflectance and air-gap attenuators may have high reflectance, we do not recommend using them on singlemode systems. Filter type attenuators with low reflectance are recommended. Here's more on attenuators from our new Online Fiber Optic Reference Guice.
We're covering these topics (and a lot more) in our new FOA Online Fiber
Optic Reference Guide: http://www.thefoa.org/tech/ref/index.html and
We have added a section on Premises Cabling on the FOA Online Reference Guide To Support our New Pemises Cabling Certification. Soon we'll also have a study guide for the CPCT on the FOA Online Reference Site.
Design certification training is also starting at FOA-approved schools.
40 and 100 gigabit/sec Ethernet
Who wants 40-100G networks? Streaming video? Nah, how about universities and brokerage houses. At least that's what Freesky Research claims in a article in Lightwave. The brokerage houses need high speed links to cut microseconds off their transaction times. We're often skeptical of market research, as its often self-serving, but this one is so asking to be a news parody on the Daily Show.
ACTIVE OPTICAL CABLES (AOC - fiber optic cables with media converters on each end so they act like electronic cables) have created considerable “buzz” in the optical connectivity business over the past year. Active Optical Cables Market Analysis 2009, IGI's first report on the AOC market, examines several market segments expect to generate significant business growth over the next five years. The report includes fifteen separate market segment forecasts, covering four platform types, four bus standards, and five platform categories. It contains over 160 figures and tables. According to the report, cumulative cable revenue is expected to exceed $8.5 billion (US) from 2009 through 2013 just for the application segments included in this report. Single-year revenue is expected to grow from the present-year level of <$100 million to over $1.1 billion in 2010, then up to over $2.6 billion by 2013. As additional application segments are included in the overall market, the total revenue numbers can be expected to increase substantially over these conservative figures.
IGI is offering a 20% pre-publication discount on the report until January 1, 2009. For more information on this report, please visit igigroup.com or contact:

Coming soon to a network near you - 40 and 100 gigabit/sec Ethernet!
The IEEE is already working on specs for 40 and 100 gigabit/sec Ethernet and have approved a number of new PMDs (that's standards-speak for Physical Medium Dependent - i.e. cabling). A summary of the proposals is on the updated list of network specs at http://www.thefoa.org/tech/Linkspec.htm.

FTTH "Take Rates" Now at 30%
About 1/3 of all subscribers offered FTTH are not taking it according to RVA quoted in Telephony Online. In underserved areas, it's over 50%. Partly it's because FTTH is developing the reputation as the best service but partly the take rate is up because the companies are able to hook up subscribers faster.

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:
Of special interest is their "Best Practices" Manual, available for downloading. If you do OSP installs, please get yourself a copy and read it.
