WDM System
Mux/Demux Single Fiber CWDM Module
Description:
CWDM technology uses ITU standard 20nm spacing between the wavelengths, from 1270nm to 1610nm. Our CWDM module has 2 to 18 channels. The central wavelength of each channel is specified to one of the ITU-T grid wavelengths. The CWDM module features wide channel bandwidth (13nm). Its isolation is greater than 30dB for adjacent channels,and greater than 40dB for non-adjacent channels. The module also has high thermal stability to ensure reliable performance under different environment.
