Section 9: Fiber Amplifiers

Fiber amplifiers are commonly used in fiber communication systems in the same way an amplifier circuit may be used in a PCB, or radio repeaters are used to amplify weak radio signals that are fighting the curvature of the Earth, in that it amplifies an otherwise potentially weak signal. As one may imagine, over long haul communication distances, our best efforts to curb spurious losses to absorption would be defeated, and it would be necessary to amplify the signal once more. Hence, fiber amplifiers! Another use though in high power implementations is to, obviously, achieve higher energy output pulses. Both applications can be explained using the general descriptions of fiber amplifiers and their working principles.
