Leading Optical Technology 2~18CH CWDM Multiplexer-MUX DEMUX ABS
BOX MODULE in CWDM Multiplexing
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.
