CWDM (Coarse Wavelength Division Multiplexing) is a cost-effective optical communication technology that transmits multiple data streams simultaneously over a single optical fiber. Unlike DWDM (Dense Wavelength Division Multiplexing) with narrow channel spacing, CWDM typically uses 20nm spacing across the optical spectrum.
The technology assigns distinct, non-overlapping wavelengths to different data signals, combining them at the transmission end for joint fiber transmission, then separating them back to individual signals at the receiving end. CWDM filters selectively pass or block specific wavelengths to enable this signal management.
