Optical Fiber CommunicationsThe 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. |

In this case since the input NA of the receiving fiber is larger than the equilibrium
NA of the emitting fiber , slight mechanical misalignments of the two joined fibers
and small variations in their geometric characteristics do not contribute ...

An experimental comparison of the losses induced by the three types of
mechanical misalignments is shown in Fig . 5 - 14 . The measurements were
based on two independent experiments using LED sources and graded - index
fibers .
