The first generation networks built before the emergence of fiber optics and the second generation networks which used fiber as a replacement for copper links in Local Area network (LAN), Metropolitan Area Network (MAN) and Wide Area Network (WAN) are not adequate to meet the emerging integrated demands of the communication applications. Huge bandwidth must be provided to support applications such as super-computer interconnect, videoconferencing, etc., co-existing with smaller bandwidth requirements of data, audio, and many other applications for thousands of end-users. Wavelength Converters in Optical Networks deals with the third generation networks that use Wavelength Division Multiplexing (WDM), wavelength routed optical networking technology. This technology can efficiently utilize the enormous bandwidth of the optical fiber and has been able to meet the emerging integrated demands of the communication applications.
