About the Book
Optical Fiber Communication System is written for the undergraduate students of Electrical, Electronics and Communication Engineering. Written in a lucid language, and organized in 12 chapters, the book discusses light propagation in optical fibers, transmission characteristics of optical fibers, signal degradation, fabrication and characteristics of light emitting diode, fabrication and characteristics of lasers, power launching and coupling, optical detector, analysis and performance of optical receiver, network and application.
Using a mathematical approach with well-illustrated explanations and numerous solved examples, this book reflects the expertise of the author who has an experience of more than 20 years in teaching. A useful appendix at the end of the book gives mathematical pre-requites for readers.
