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.

where VB is the breakdown voltage at which M goes to infinity ; the parameter n
varies between 2 . 5 and 7 , depending on the material ; and V = V - IMRM , with
Va being the reverse - bias voltage applied to the detector , Im is the multiplied ...
The parameter Ln is given by Eq . ( 7 - 58 ) . It depends on the pulse energy per
bit period ( y ) and on the excess noise coefficient x of the avalanche process .
For a gaussian input pulse , y , in turn , depends on the parameter a in Eq . ( 7 -

2 Amplifier Gain One of the most important parameters of an optical amplifier is
the signal gain or amplifier gain G , which is defined as Ps . out G = ( 11 - 9 ) Ps .
in where Ps , in and Ps , out are the input and output powers , respectively , of the
