Choosing the right fiber optic cable is extremely important for any installation. The purpose of the cable is to protect the fibers during installation and the service lifetime. Several types of cable are available.
Fiber optics is full of jargon but it’s important to understand it. One of the more confusing terms to many is “wavelength.” It sounds very scientific, but it is simply the term used to define what we think of as the color of light.
Regarding safety in fiber optic installations, the first thing that comes to mind is usually eye damage from laser light in the fiber. People imagine a laser burning holes in metal or perhaps burning off warts.
Well, we’ve heard it all before—fiber to the desktop (FTTD) is on its way to becoming the power source of choice. While unshielded twisted pair (UTP) cabling has been dominant, there is reason to think fiber will be a true competitor soon.
It seems as if it was only a decade or so ago when “migration” refered only to birds (or perhaps retired people) heading south for the winter. Now, the term “migration” has taken on a whole new meaning.
It may seem unbelievable, but fiber optic links and networks have been used for over 20 years. The first telco networks were installed in the late 1970s and data links were already in use by 1980, when there were few personal computers (PCs) and computer networks.
After a fiber optic cable plant is installed, it may be used with several different types of fiber optic networks. Computer networks, telephone signals, video links, and even audio can be sent on the installed fibers. Each network type has a performance requirement for the fiber optic cable link.
There are many instances where converting from copper to fiber is necessary or more cost-effective. Sometimes it’s done just to showcase new technology. But whatever the reason, making the conversion has become simple and inexpensive. Converting to fiber is sometimes the only technical solution.
Practically everything I know about estimating fiber optic jobs I learned from Doug Elliott. Doug is a well-known instructor who learned fiber optics from me at the first Fiber U in 1993 and is a full-time installer in the Toronto area.
Testing installed fiber optic cabling or patchcords is not difficult, but sometimes it seems the results you get don’t make sense. After 20 years in the business, I’ve probably seen most of the possible errors. If I share them with you, perhaps you will avoid them.
In last month’s Electrical Contractor, we wrote about how to improve your fiber optic termination techniques. Fiber optic connector manufacturers work hard to make terminations easier and less expensive, and with higher performance capabilities.
There’s no doubt that termination of fiber optic cables is the most difficult part of the fiber optic installation process. Pulling cables is easy, as they are more rugged than Category 5 copper cables, and installing patch panels and other hardware is straightforward.
We all know about maintenance. We know things wear out or get dirty and need replacing or cleaning. This is especially true about cars. We regularly change the oil and filter, rotate the tires, and get the engine tuned up to keep our vehicles running well.
Last month, we discussed the centralized fiber optic architecture and how it affected network design. This month, we’ll continue the discussion, looking at how this can affect the design and/or need for a telecommunications closet (TC).
CityNet Telecommunications Inc. has launched the first commercial deployment of a fiber optic network through a sewer system. The first-of-a-kind deployment was conducted in the city of Albuquerque, N.M.
Having lit a large stuffed elephant in Wisconsin, and a three-story high wooden one in New Jersey, CLI was then called upon to light a resident goat in a full-scale reproduction of an 1100 B.C. Iron Age house in Canaan.
