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.

Equations (4-59) and (4-60) indicate that, to increase the light source lifetime, it is
advantageous to operate these devices at as low a current and temperature as is
practicable. Examples85 of the luminescent output of InGaAsP LEDs as a ...
Catastrophic facet degradation is mechanical damage of the facets that may arise
after short operating times of laser diodes at high optical power densities. This
damage tends to reduce greatly the facet reflectivity, thereby increasing the ...
Using these components, the engineer wishes to construct a 5-km link operating
at 20 Mb/s. If the sensitivities of the pin and APD receivers are -45 and -56 dBm.
