Transmitting information over optical fibers requires a high degree of signal integrity with respect to noise levels existing in optical systems. The methods and techniques for noise evaluations are important so that high performance can be obtained. This book provides a fundamental understanding of noise generation processes in optical communications and photonic signals. It discusses techniques for noise evaluation in optical communication systems, especially digital optical systems, as well as transmission system performance and noise impacts in photonic processing systems.

Arvustused

"The topics studied in this book are very interesting. This book is very useful for people who work on photonic systems and optical communications." Robinson Cruzoe Guzmán Martínez, University Carlos III of Madrid, Spain

"...the book is richly illustrated with diagrams and charts that describe the performance of practical systems, a precious reference for both students and professionals." Optics & Photonics News, June 2017
