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.

A Si atom has four electrons in its outer shell , by which it makes covalent bonds
with its neighboring atoms in a crystal . ... so that both can contribute to electrical
conductivity ; that is , an electron in the valance band can move into a vacant ...
Here , T is the temperature in degrees Kelvin , kb is Boltzmann ' s constant , h is
Planck ' s constant , and me and mn are the effective masses of the electrons and
holes , respectively , which can be smaller by a factor of 10 or more than the free
electron concentration in the conduction band , as shown in Fig . 4 - 26 . Since in
this type of material the current is carried by ( negative ) electrons ( because the
electron concentration is much higher than that of holes ) , it is called n - type ...
