Chapter 14. Optical Networks and WDM Systems
Optical communication systems have been developed to meet two main objectives: reaching higher data transmission bandwidths and reducing the overall cost of communication networks. Optical communication technology uses principles of light emission in a glass medium, which can carry more information over longer distances than electrical signals can carry in a copper or coaxial medium. This chapter focuses on principles of optical communications, optical multiplexing, and switching used in optical computer networks. Following are the major topics covered:
• Overview of optical networks
• Basic optical networking devices
