The Next Step C/D-WDM is a bidirectional passive optical multiplexer/demultiplexer enabling several optical channels of different wavelengths to be combined or separated. This allows for multiple services to be transmitted over fiber without interference. Each module can perform WDM MUX or DEMUX for up to 10 channels - or up to multiple channels when cascading modules in the Next Step Patch Panel.
