Chapter 3 Optical Communication Fundamentals
The ultimate goal of the optical signal transmission is to achieve the predetermined bit error ratio (BER) between any two nodes in an optical network. The optical transmission system has to be properly designed to provide reliable operation during its lifetime, which includes the management of key engineering parameters.1
This chapter describes the key optical components used in a contemporary optical communication system; basic signal and noise parameters; major channel impairments, including chromatic dispersion, polarization mode dispersion (PMD), and fiber nonlinearities; and the system design process. This chapter is based on references 1–22.
The chapter is organized as follows. After a brief ...
