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. |

The core is surrounded by a solid dielectric cladding having a refractive index n2
that is less than ny . Although , in principle , a cladding is not necessary for light to
propagate along the core of the fiber , it serves several purposes .

Solving Maxwell ' s equations shows that , in addition to supporting a finite
number of guided modes , the optical fiber waveguide has an infinite continuum
of radiation modes that are not trapped in the core and guided by the fiber but are
still ...

28 The area A in this case is the core cross section ma2 . The factor 2 comes from
the fact that the plane wave can have two polarization orientations . The total
number of modes M entering the fiber is thus given by M = 241 = 27°a " ın ?
