The 4 channel CWDM passive?MUX?DEMUX?modules deliver the benefits of a Coarse?Wave Division Multiplexer in a fully passive solution.With?matching?MUX?DEMUX?units placed at each end of an optical link, up to 4 data channels can be combined and transmitted over a single-mode fiber trunk.
It covers all channels from 1270nm to 1610nm in 20nm increments
