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.

Use the expression for b given by Eq. (3-276). 3-16. Derive Eq. (3-30) by using a
ray-tracing method. 3-17. Consider a step-index fiber with core and cladding
diameters of 62.5 and 125 nm, respectively. Let the core index n\ = 1.48 and let
The parameter L„ is given by Eq. (7-58). It depends on the pulse energy per bit
period (y) and on the excess noise coefficient x of the avalanche process. For a
gaussian input pulse, y, in turn, depends on the parameter a in Eq. (7-63).
Derive the expression for the mean-square noise voltage at the equalizer output
given by Eq. (7-28). 7-10. (a) Shows that Eqs. (7-30) and (7-33) can be rewritten
as Eqs. (7-43) and (7-44). (b) Show that Eq. (7-28) can be rewritten as Eq. (7-45).
