Some customers are asking for the difference of the CWDM and DWDM technology.
CWDM and DWDM both use the Wavelength Division Multiplexing (WDM) technology, but with different features. As shown in the below picture, there is a comparison between CWDM and DWDM technology. A CWDM MUX/DEMUX deals with small amounts of wavelengths, only up to 18 CWDM wavelength, but with large spans between wavelengths (spaced typically at around 20nm, from 1270 nm to 1610 nm).
A DWDM MUX/DEMUX deals with narrower wavelength spans (no more than 0.8nm, 0.4nm or perhaps 0.2nm), and may accommodate 40,80, or even 160 wavelengths(mostly used is Channel 17 to Channel 61 wavelength).
