Optical Fiber Technology
|The optical fiber concept has been around for more than a century. From the early experiments by John Tyndall in the guided transmission light, through the development of light-emitting diodes and lasers, and the emergence of dense wavelength-division multiplexing, the applications for optical fiber have continued to grow. Today, optical fiber technologies permeate a variety of industries. For instance, delivering high-definition broadcast (HDTV) at resolutions of 1080p has become possible through the deployment of fiber-to-the-curb (FTTc or FTTh) networks. Satellites transporting L-Band signals over fiber do not need to be demodulated, and also suffer less attenuation.

A device, inserted within a transmission path, that boosts the strength of an electronic or optical signal. Amplifiers may be placed just after the transmitter (power booster), at a distance between the transmitter and the receiver (in-line amplifier), or just before the receiver (preamplifier).
