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.

Gerd Keiser. 5-7. On the same graph, plot the maximum coupling efficiencies as
a function of the source radius r, for the following fibers: (a) Core radius of 25 fim
and NA = 0.16. (b) Core radius of 50 /xm and NA = 0.20. Let r, range from 0 to 50
That is, the output pulse response pout(t) of the fiber can be calculated through
the convolution (denoted by *) of the input pulse #„(') and the power impulse
function h(t) of the fiber. The period T between the input pulses should be taken
to be ...
Consider a signal x(l) that is passed through a linear system having a transfer
function h(t). The output signal is given by >•(/) = h(t)x(t) If x(t) is modeled in the
frequency domain by a spectral density Gx(f) and the linear system has a transfer
