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).
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.
Glass fiber optics lighting is composed of three compatible parts. First-time users should consult with a qualified supplier to create a bill of materials. A light source: (called an illuminator or projector) is conveniently located in a readily accessible place for relamping.
Last month, we mentioned centralized fiber local area networks (LANs) as a place where fiber optics are more cost effective than copper wiring. What exactly is a centralized fiber network and how is one designed and built?
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.
Fiber optics is always expected to cost much more than copper cabling. Whatever you look at—cable, terminations, or networking electronics—fiber costs more. So isn’t it obvious that fiber networks are more expensive than copper? Maybe not! There is more to consider before deciding this.
Our local newspaper reported that the local phone company had completed installing fiber optic cables between their central offices in the Boston area. That didn’t surprise me, but what did was the description of the cables they were installing. Each cable had 864 fibers in it!
Up until a couple of years ago, one never thought about choosing the fiber in the fiber optic cable you bought. If you were buying cable for outside plant applications like telephone or CATV networks, you chose single-mode fiber.
It has the potential to be a classic cartoon: an electrician with a run of co-ax coming in on the left that needs to link to a run of fiber going out on the right. No amount of black tape will link the two. What is needed is a magic box.
Absorption: That portion of fiber optic attenuation resulting in conversion of optical power to heat.
Attenuation coefficient: Characteristic of the attenuation of an optical fiber per unit length, in dB/km.
