The Development Process of Wavelength Division Multiplexing Technology
By using WDM and optical amplifiers, they can accommodate several generations of technology development in their optical infrastructure without having to overhaul the backbone network. The capacity of a given link can be expanded simply by upgrading the multiplexers and demultiplexers at each end. Originally, the term coarse wavelength-division multiplexing (CWDM) was fairly generic and described a number of different channel configurations.
