The  ODM  (Optical  Demultiplexer/Multiplexer)  Card  is  a  CWDM  (Coarse  Wavelength  Division Multiplexing) / DWDM (Dense Wavelength Division Multiplexing) multiplexer launched by DFT . It  can  combine  or separate the  channels  of  CWDM or  DWDM  systems, greatly  saving the fiber resources of customers, and the network configuration can be flexibly changed according to customer requirements.

For  DWDM  systems  with  a  frequency  spacing  of  100GHz,  it  supports  smooth  upgrade  to  48 wavelength channels. For DWDM systems with a frequency spacing of 75GHz, it supports smooth upgrade to  64 wavelength channels.  For  DWDM systems with a frequency spacing of 50GHz,  it supports  smooth  upgrade  to  96  wavelength  channels .  For  CWDM  systems,  it  supports  smooth upgrade to 18 wavelength channels.

The  use of the  ODM device can  improve the spectrum  utilization of the fiber and save  precious bandwidth resources.
