100GHz DWDM Module (4,8,16,32 channel)
DWDM (Dense Wavelength Division Multiplexer) is a dense wavelength division multiplexer. The channel interval of DWDM is 1.6/0.8/0.4nm, which is much smaller than that of CWDM. Compared with CWDM, DWDM, which has a tighter wavelength interval, can carry 8 to 160 wavelengths on a fiber, and is more suitable for long-distance transmission. With the help of EDFA, DWDM systems can operate over a range of thousands of kilometers.
