Coarse Wavelength Division Multiplexing (CWDM) is a wavelength multiplexing technology for fiber access networks. It provides flexibility to increase the capacity of existing fibers, and create more connections over a single fiber. Data transmission is realized by using max 18 channels CWDM with wavelengths between 1270nm and 1610nm.
The CWDM is protocol transparent and suits applications including 10/1G Ethernet, SDH/SONET, 8/4/2/1G Fibre Channel, FTTx, CATV, and widely used as a wavelength multiplexing technology for city and access networks.
