WebIn WDM systems, a channel is a single, unique transmission at a designated wavelength that may occur along with other channels having different wavelengths. A transmission channel can also refer to the end-to-end physical path. Sometimes used to identify a group of WDM wavelengths that are combined and associated with a single fiber path or span. WebThe channels on CWDM are located on frequencies between 1271nm to 1611nm, whereas for DWDM the “C-band” 1530nm – 1565nm frequency range is most commonly used as the light has a lower attenuation in optical fiber at this frequency and can travel further.
