Many years ago, people complained that the most dangerous part of fiber optic work was the chance you might get your eyeballs burned by laser light in the fiber. They had confused optical fibers to the output of high-powered lasers used in labs.
According to the Wall Street Journal, Comcast will begin upgrading its networks by midyear for new DOCSIS 3.0 technology that will dramatically increase Internet connection speeds, and the success of the initiative will determine how aggressive Time Warner Cable, Cox Communications and Charter Commu
Many columns have focused on components and installation issues specific to fiber optics. Component selection and installation all must be preceded by the design process, where the overall network is configured.
I know I have said enough about industry standards, so this will not be another column on that topic. However, I’m going to recruit you and your customers to create a new standard using a time-proven technique—just doing what makes sense! You see, standards come in two very distinctive varieties.
Often at this time, we look back at the past year to see what happened and look forward to the new year, wondering what comes next. While we do that, we promise ourselves to break old, bad habits and adopt new, better ones.
Recent events have lead me to carefully consider the meaning of standards. I spent more than a dozen hours helping an end-user and a cabling contractor understand what TIA-568 required (and/or allowed) for fiber optic testing.
Like many others involved in technical education, I have been guilty of continually telling you that you need to get more training. The best way to keep up with technology, products or the industry; enhance skills; or network with peers is to attend training seminars.
In the quiz (page 76), we ask some questions about choosing voice/data/video (VDV) cabling components for various applications. With so much changing in communications, cabling technology and standards, figuring out which components to use in a particular application can be tricky.
Here is one word of advice I offer to anyone asking about maintenance of fiber optic networks: DON’T! Some people have suggested fiber optic networks need periodic inspection of connectors, mating adapters and even testing or taking optical time domain reflectometer (OTDR) traces.
Fiber optics is not a new technology, having been available for communications for more than two decades now, but fiber still seems to have the “rocket science” aura. (In the interest of full disclosure, I once was a rocket scientist.
Coupled with impressive growth in its broadband subscriber base, the Asia/Pacific region is standing at the forefront of the fiber to the home/node/business (FTTx) evolution, according to the high-tech market research firm In-Stat, Scottsdale, Ariz.
Proper OTDR parameter setup eases interpretation: The Optical Time Domain Reflectometer (OTDR) is an essential instrument for characterizing long outside plant fiber optic cables; it is the only instrument capable of verifying inline splices on concatenated fiber optic cables and locating faults.
