narrow WDM (NWDM)

Narrow Wavelength Division Multip lexing (NWDM) is a wavelength division multiplexing (WDM) in the 1,300 nm range that typically operates with four wavelengths at a wavelength spacing of 25 nm. In contrast, coarse wavelength division multiplexing (CWDM) operates with 18 channels and dense wavelength division multiplexing (DWDM) operates with up to 160 wavelengths.
