(In topic `Network Architectures`) DWDM, an acronym for dense WDM, is one of the major enabling technologies for optical networks and is used, for example, in Lucent Technologies` WaveStar optical networks. Lucent is the global leader in deploying DWDM technology. Its Wavestar systems enable transmission at speeds of up to 400 gigagbits per second ...
