4 Channels CWDM Mux Demux, 1270-1330nm, 1.0dB Typical IL, LC/UPC, Dual Fiber, FMU Plug-in Module

4 Channels CWDM Mux Demux, 1270-1330nm, 1.0dB Typical IL, LC/UPC, Dual Fiber, FMU Plug-in Module 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 3C CWDM optical transceivers and OADM, etc., this Mux Demux supports a wide range of architectures from simple point-to-point to amplified ring configurations.
