CWDM is also called sparse wavelength division multiplexing and coarse wavelength division multiplexing. It is a technology that uses optical multiplexers to multiplex the wavelengths transmitted in different optical fibers into one optical fiber for transmission. It has fewer channels than Dense Wavelength Division Multiplexing (DWDM), but more than standard Wavelength Division Multiplexing (WDM), Opelink provide CWDM modules are available packaging: ABS Box, Rackmount and LGX Cassette.
