Passive MUX/DEMUX products for CWDM and DWDM

TXO provides MUX/DEMUX units for both CWDM and DWDM networks and can also supply the range of optical transceivers associated with these devices. In telecoms networks, MUX (pronounced “mucks”) is an abbreviation for multiplexing. A MUX is a device that combines multiple signals over a channel at the same time in the form of a single complex signal. At the receiving end another device, called a DEMUX, then recovers the individual strands. These devices consume no power and hence are known as passive devices.

The main differences between MUX/DEMUX devices for CWDM and DWDM is the number of channels and ports.

 

Channels:

  • CWDM can have 18 channels whereas DWDM can have up to 96 channels. Hence the coarse in CWDM (Coarse Wavelength Division Multiplexing) relates to larger channel spacing than found in DWDM (Dense Wavelength Division Multiplexing).

 

Ports:

  • CWDM is available in 8 port and 16 port configurations.
  • DWDM is available in a larger range of ports; common configurations are 4, 8, 16 and 32.
