Optical Fiber Communications
The third edition of this popular text and reference book presents the fundamental principles for understanding and applying optical fiber technology to sophisticated modern telecommunication systems.
Optical-fiber-based telecommunication networks have become a major information-transmission-system, with high capacity links encircling the globe in both terrestrial and undersea installations. Numerous passive and active optical devices within these links perform complex transmission and networking functions in the optical domain, such as signal amplification, restoration, routing, and switching. Along with the need to understand the functions of these devices comes the necessity to measure both component and network performance, and to model and stimulate the complex behavior of reliable high-capacity networks.

At a fixed low signal level , as the gain is increased from a low value , the signal -
to - noise ratio increases with gain until the quantum noise term becomes
comparable to the circuit noise term . As the gain is increased further beyond this
As the input signal level is increased , excited carriers ( electron - hole pairs ) are
depleted from the active region . When there is a sufficiently large optical input
power , further increases in the input signal level no longer yield an appreciable ...
