CWDM Module for CATV Fiberoptical System with low insertion loss and high channel isolation
Descreption:
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 1271nm to 1611nm.
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 module also has high thermal stability to ensure reliable performance under different environment.
