Product Description

CE RoHS Approved CWDM Mux /Demux Low PDL High Reliability And Stability
CWDM is using optical multiplexers to reuse different wavelengths of light into a single fiber to transmit signals.
At the receiving end of the link, the mixed signal is decomposed into signals in the fiber by means of an optical demultiplexer.
Different wavelengths are connected to the corresponding receiving equipment.
