    The wavelength spacing in coarse wavelength division multiplexing is typically nm

    The wavelengths are spaced out by 20 nanometers which allows up to 18 channels to be accommodated within the 1270 nm to 1610 nm spectrums. This spacing is beneficial because CWDM can be less expensive than utilizing other spacing lasers due to the reduced inter-channel interference. CWDM was standardized by the ITU-T G. It can carry up to 18 CWDM wavelengths over one pair of fibers. The channels are combined and transmitted over a single fibre optic cable.
