Product Description

High Performance CCWDM 4 Channel Mux Demux With Low Profile Modular Design



Compact Coarse Wavelength Division Multiplexing CCWDM networks need multiplexer/de-multiplexer (MUX/DEMUX) modules to combine and split the multi-wavelength optical signals. These modules are generally called CWDM MUX/DEMUX. Coupled with highly reliable passive optics (e.g., CWDM SFP/SFP+), CWDM MUX/DEMUX modules let operators make full use of available fiber bandwidth in local loop and enterprise architectures. Power link provides a series of CWDM MUX/DEMUX modules with as more as 18 channels in simplex or duplex configurations.
