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.

Couplers with 64 inputs and outputs are possible , although , more commonly ,
the size tends to be less than 10 . ... When discussing couplers and splitters , it is
customary to refer to them in terms of the number of input and output ports on the
10 - 4 , with Po being the input power and Pi and P2 the output powers , then
Splitting ratio = ( 012 . ) x 100 % Pi + P2 ) ( 10 - 4 ) By adjusting the parameters so
that power is divided evenly , with half of the input power going to each output ...
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
