Crafted by QSFPTEK, the Single Fiber 9-channel CWDM MUX/DEMUX covers wavelengths from 1270nm to 1590nm, supports 9 channels difference business in one core optical fiber for point-to-point transmission. It works in Broadcast and TV, IDC, finance, government, cloud, massive data and other industries, where the optical fiber resource are rare.
Use CWDM Mux Demux for Multiple 10G CWDM Networks up to 10KM: 
The 1270nm-1590nm channel port for CWDM traffic, monitor port for network link monitoring

The DWDM Mux Demux essentially combines multiplexing (Mux) and demultiplexing (Demux) functions. At the transmitting end, the Mux combines optical signals of different wavelengths into the same fiber for transmission; at the receiving end, the Demux separates these mixed multi-wavelength signals and restores them to their individual channels. The overall process is one of "merging" at one end and "demultiplexing" at the other, corresponding to each other.

WDM technology enables diverse data transmissions over a single fiber, reducing the need for multiple dedicated fibers per service.
It serves as a cost-effective network solution by optimizing the utilization of optical fibers.
