Emerging Technology for Fiber Optic Data Communication

Chung-Sheng Li,      IBM T. J. Watson Research Center

Due to the continued rapid growth in the demand for network bandwidth, devices and subsystems that can support gigabit and multigigabit throughput have become increasingly important. In this chapter, we review several key technologies for fiber optic data communication. In particular, we focus on the technologies for wavelength division multiplexing (WDM), as it is the most important technique in advancing the communication bandwidth for the next generation broadband networks.
