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.

COS0i = /22COS02 (2-17) where the angles are defined in Fig. 2-6. The angle <p
\ between the incident ray and the normal to the surface is known as the angle of
Rays striking the core-cladding interface at angles less than 0mjn will refract out
of the core and be lost in the cladding. By applying Snell's law to the air-fiber face
boundary, the condition of Eq. (2-21) can be related to the maximum entrance ...
