12.8.2020 | Coarse wavelength division multiplexing (CWDM)
Applies to greater separation of wavelengths than DWDM. In the case of single-mode applications CWDM defines 20-nm separation from 1270nm to 1610nm, with 1470nm to 1610nm the most commonly used wavelengths. With multimode fibers, the wavelengths are 778, 800, 825 and 850 nm.
