Computer networks (LANs) started using fiber about the same time as the telcos

November 30, 2011

Computer networks (LANs)http://www.fiberise.com started using fiber about the same time as the telcos. Industrial links were among the first applications as the noise immunity of fiber and its distance capability make it ideal for the factory floor. Connecting graphics displays and mainframe storage links, the predecessors of today's fiber SANs (storage area networks) in data centers came next. Today fiber is used in most corporate LANs as backbones, connections to desktops for engineering or graphic workstations and many wireless access points.

Which Fiber Optics?

November 30, 2011

Whenever you read an article or talk to someone about fiber optics, you need to know the point of view. We're mainly concerned with communications fiber optics, but it's also used in medical or nondestructive testing inspection and lighting. Fiber optics, you see, is not all the same.

Outside Plant (OSP)

November 30, 2011

Telephone companies, CATV and the Internet all use lots of fiber optics, virtually all of which is singlemode fiber and most of which is outside buildings. It hangs from poles, is buried underground, pulled through conduit or is even submerged underwater. Most of it goes relatively long distances, from a few hundred feet to hundreds of miles.

Premises Cabling

November 30, 2011

By contrast, premises cabling- cabling installed in a building or campus - involves shorter lengths, rarely longer than a few hundred feet, typically with fewer fibers per cable. The fiber is mostly multimode, except for the enlightened user who installs hybrid cable with both multimode and singlemode fibers for future high bandwidth applications.

TIA/EIA-568 is a set of three telecommunications standards

November 29, 2011

TIA/EIA-568 is a set of three telecommunications standards from the Telecommunications Industry Association, a 1988 offshoot of the EIA. The standards address commercial building cabling for telecom products and services. The three standards are formally titled ANSI/TIA/EIA-568-B.1-2001, -B.2-2001, and -B.3-2001.The TIA/EIA-568-B standards were first published in 2001.

history of TIA/EIA-568

November 29, 2011

TIA/EIA-568 was developed through the efforts of more than 60 contributing organizations including manufacturers, end-users, and consultants. Work on the standard began with the Electronic Industries Alliance (EIA), a standards organization, to define standards for telecommunications cabling systems.
