Passive CWDM
Part number： Views：137
Coarse Wave Division Multiplexing (CWDM) modules combine or split up to 18 wavelengths into a single fiber.
CWDM technology uses ITU standard 20nm spacing between the wavelengths, from 1270nm to 1610nm. Our
CWDM module has 4 to 18 channels. The central wavelength of each channel is specified to one of the ITU-T grid
wavelengths. The CWDM module featu
