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.

Suppose the following two optical signals are launched simultaneously into the
fiber: an optical power of 150iiW at 1300 nm and an optical power of 100MW at
1550 nm. What are the power levels in aiW of these two signals at (a) 8 km and (b
To see the effects of the different noise terms on the carrier-to-noise ratio, Fig. 9-6
shows a plot of C/N as a function of the optical power level at the receiver. In this
case, we see that at high received powers the source noise dominates to give a ...
In specifying the performance of an optical coupler, one usually indicates the
percentage division of optical power ... A 2 x 2 biconical tapered fiber coupler has
an input optical power level of Po = 200 //W. The output powers at the other three
