Transmitting information over optical fibers requires a high degree of signal integrity due to noise levels existing in optical systems. Proper methods and techniques for noise evaluations are critical in achieving high-performance.
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 systems performance and noise impacts in photonic processing systems
