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.

In copper cables the wires themselves are generally the principal loadbearing
members of the cable , and elongations of more than 20 percent are possible
without fracture . On the other hand , extremely strong optical fibers tend to break
at 4 ...
5 percent . Compare the modal dispersion in units of ns / km of this fiber as given
by Eq . ( 3 - 30 ) with the more exact expression Omod = " 7 " ? ( 1 - 7 ) where L is
the length of the fiber and n2 is the cladding index . 3 - 18 . Verify that Eq . ( 3 ...
