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.

Materials that satisfy these requirements are glasses and plastics. The majority of
fibers are made of glass consisting of either silica (SiO2) or a silicate. The variety
of available glass fibers ranges from high-loss glass fibers with large cores ...

Strength and static fatigue are the two basic mechanical characteristics of glass
optical fibers. Since the sight and sound of shattering glass are quite familiar, one
intuitively suspects that glass is not a very strong material. However, the ...
