The 4CH Mux Demux is a cost-effective, flexible, and suitable for short-distance transmission passive CWDM device based on Free Space technology. This unit can be used as either a multiplexer or de-multiplexer (mux/demux). In accordance with the ITU-T G.694.2, it maximizes the capacity of the C-band range.
In conjunction with FS CWDM optical transceivers and OADM, etc., this Mux Demux supports a wide range of architectures from simple point-to-point to amplified ring configurations.
