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. |

When solving Maxwell ' s equations for hollow metallic waveguides , only
transverse electric ( TE ) modes and transverse magnetic ( TM ) modes are found
. However , in optical fibers the core - cladding boundary conditions lead to a

Using these approximations , Eq . ( 2 - 54 ) becomes Jo + K = + ( 6 + d ) ( 2 - 62 )
Thus , Eq . ( 2 - 55b ) for TEom modes is the same as Eq . ( 2 - 566 ) for TMom
modes . Using the recurrence relations for J ' and K given in App . C , we get two
