Broadband Benefits From US Economic Stimulus Plan


As we mentioned last month, the American Recovery and Reinvestment Act of 2009 includes funding for expanding broadband coverage in the US. The direct package has $7.2 billion devoted to expanding the reach broadband, with $2.5 billion handled by RUS, Rural Utilities Services (http://www.usda.gov/rus/), a department of the Agriculture Department, and $4.7 billion by NTIA, National Telecommunications and Information Administration (http://www.ntia.doc.gov/), a division of the Commerce Department. The RUS and NTIA must award all funds by September 30, 2010. Funds can be grants or loans, expanding the long term effects. Since RUS requires the money go to approved organizations, rural telcos are most likely to benefit. NTIA funds require the recipient to provide 20% of the project cost, so the telcos will be able to use it to leverage their capital expenditures.

Besides fiber backbones, wireless is an option in broadband, of course, and will be part of the likely infrastructure built using this program. But of the 10,000 or more jobs this program is set to create, many will benefit fiber optic techs.

This is not the whole of the benefits to communications. A major initiative is digital health records, with a necessity to connect medical facilities to high speed access also. That program starts with close to $20 billion.

FOA Updating Advanced & Specialist Certifications
The FOA has been reviewing all the certifications and updating those  which need it, generally for technical reasons.
This time around, we have updated the AFOT which has until now only been available through schools to make it available to CFOTs with at least one year of continuous work in the fiber optic field. CFOTs can apply for the AFOT if they have the experience and can take the test online with a proctor.
We are also updating the CFOS Specialist Certifications for Splicing, Connectors and Testing. They will be available to CFOTs who meet the experience requirements and take an online test or who attend one of the CFOS courses offered at several FOA-Approved schools.
A big advantage for those studying for AFOT or CFOS exams will be the use of the FOA Onlnie Reference Guide as a study guide for the exams. Watch for more info on the AFOT and CFOS certifications next month.




Do We Need a New Internet?
The term "Wild West" was how  Bob Metcalfe, co-inventor of Ethernet, described the Internet when we were on a panel together at ComNet a decade ago. (Complete with outlaws, robber barrons, land rushed, etc.) When the Internet was created, it was for the use of researchers and government personnel, not everybody. Security, therefore, was not an issue. Now serious consideration is being given to whether the current Internet can be “saved” from hackers, viruses and spam. Should we try to fix what we have or start over with some serious concerns over security?
Here is a NY Times article on what may be coming.




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. Recently we added sections on FTTHpremises 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

Good Question! Tech Questions Worth Repeating

Q: Is there any convertor or X equipment that could transport 1 Gbps over standart MM FO cable 2 km.

A:For 850 nm we know of no solution for more than 1100 meters. We can select special OM4 fiber to make 1100 meters, but beyond that I think you will not find a solution. However, 1300nm is no problem and you will find many possibilities. Draka for instance offers our HiCap 50um fiber, which is optimized around 1300nm. I suppose our competitors must also offer comparable. (Thanks to Chappell Ryan of Draka Communications (http://www.draka.com/) for this answer.)
~~~~~~~~~~~~~~

Q:
If I test a FO link from both sides, am I suppose to get the EXACT distance reading?
A Contractor is busy installing some FO systems.  The OTDR result from one side show 14,5189 km and on the same fibre from the other side his machine gives a result of 14,5577 km...  to me this is about 39 meters difference. I try and understand this.

A: Let's look at the numbers: The difference in readings is 14518.9 to 14557.7 or 38.8 meters. That's a difference of 0.27 percent. The resolution of the instrument is 0.1 m or 0.006 percent of the reading.

How does the OTDR measure distance of a length of fiber? It sends out a pulse and looks for the returned reflected pulse from the far end. It measures this round-trip time and divides it in half for the one-way time. It then multiplies that time by the speed of light in the fiber, defined by the effective index of refraction, something around 1.4675 (Corning SMF28, a typical fiber.)

The OTDR measurement depends on an accurate time measurement by the OTDR, knowing the speed of light in the fiber precisely and the techniques used to get and process that information.

What's the "accuracy" or "measurement uncertainty" of the instrument? Referring to the JDSU book on testing, typical OTDR accuracy is expressed as:

+/-time base error x distance +/- 1m +/-sampling resolution +/-index uncertainties.

The time base error can be 0.01 to 0.001%
The uncertainty of the index of refraction is about 0.1% to 0.01%

For this example
+/- 0.001% x 14518 m  = 14.5 m or 0.01% = 145 m
+/- 1m
+/-sampling resolution =? probably a few meters?
+/-index uncertainties. = 145 or 1450 m
Adding these up, we have a measurement uncertainty of at least 14.5+145+1=~160 m or as much as 145+1450+1=~1600 m

And that's applicable for repeatedly measuring the same fiber. From two directions, there may be differences on how the measurement markers are placed if done manually.

So the uncertainty of a 14,518.9 length measurement (+/-160 to 1600 m) is much larger than the 39 meter difference the instrument gave for bidirectional measurements.

The answer to your question, therefore, is the difference in the OTDR length measurements is due to the error inherent in making the measurement with an OTDR.

We're surprised the results were so close!

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.

JDSU Webinar series
JDSU has announced the See the Light webinar series, a four-part program designed for anyone involved in the installation, maintenance, and repair of fiber optic systems. It begins with fiber inspection and cleaning and then covers the basics of fiber testing. The webinar series then continues with the more advanced optical time-domain reflectometer (OTDR) and fiber local area network (LAN) testing challenges. More information on the series.

Interested In Fiber Optic Sensors?

Besides it's uses in communications, medicine and lighting, fiber is used for sensors. It began long ago with fiber optic gyros and chemical or acoustic sensors but has expanded to many more physical measurements. Now there's a website opticalfibersensors.org devoted to the topic. If you are involved with sensors or just want to know more about what they can do, check out this website.

FTTH Notes:

Number of Countries with Significant FTTH Market Penetration Now at 20 as More European Countries Come on Line

The number of economies where fiber to the home has established a significant and growing market presence has nearly doubled over the past 18 months, according to an updated global ranking issued today by the FTTH Councils of Asia-Pacific, Europe and North America.
The ranking, issued twice a year since 2007, was released today at the FTTH Council Europe's annual conference in Copenhagen, Denmark.  It tracks the level of FTTH market penetration in economies where more than one percent of households are connected directly into high speed fiber networks.  In all, 20 economies met this threshold, up from 14 in July 2008 and 11 in July 2007.
The growth is largely due to the entry of several European countries in the ranking, as fiber to the home deployment begins to expand across that continent and the total number of FTTH subscribers in Europe approaches two million.
Asian economies maintained their leadership in FTTH market penetration, as South Korea (44% of the market), Hong Kong (28%), Japan (27%) and Taiwan (12%) continued to hold the top four places respectively.
Meanwhile, Japan remains the overall leader in terms of the number of fiber-connected homes at 13.2 million, followed by the United States (6.05 million) and the People's Republic of China (5.96 million).
For the first time, the Councils' ranking includes the breakdown for each economy between fiber to the home connections, where fiber is run all the way to individual residences, and fiber to the building (FTTB) connections for which the fiber terminates at a multi-unit dwelling and a non-fiber local area network (LAN) delivers service to the individual subscribers.  In addition, FTTB subscriber numbers have been added to the totals for the United States, which accounts for much of the substantial increase in that country's totals since the previous ranking in July 2008.  Copper-based broadband access technologies (DSL, FTT-Curb, FTT-Node) are not included.
The breakdown between FTTH and FTTB for each economy is depicted in the following chart:

 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.

There is a new toll-free "call before you dig" number: 811

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.

FOA Certification Top Choice

The FOA CFOT and CFOS programs continue to gain momentum in fiber optics. Over 25,000 CFOTs have been certified by over 200 schools. 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 200+ organizations, welcoming new additions like the Joint Apprenticeship and Training Committee of the International Brotherhood of Electrical Workers, Corning Cable Systems and AFL (and their new acquisition "The Light Brigade" 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.

 

Understanding FOA Certifications
To answer questions on FOA certifications, we've created several new web pages:
