Multiplexer and Demultiplexer Based on CWDM

Before the introduction of CWDM multiplexer, it is necessary to mention the CWDM technology.

Originally, the term “coarse wavelength division multiplexing” (CWDM) was fairly generic, and meant a number of different things. In general, these things shared the fact that the choice of channel spacings and frequency stability was such that erbium-doped fiber amplifier (EDFA) could not be utilized. Prior to the relatively recent ITU standardization of the term, one common meaning for CWDM meant two (or possibly more) signals multiplexed onto a single fiber, where one signal was in the 1550 nm band, and the other in the 1310 nm band.

CWDM multiplexer is based on CWDM technology. It is a device to allow multiple optical signals at different wavelengths to pass through a single optical fiber strand. For convenience, we usually used “Mux” instead of “multiplexer” , and “Demux” instead of “deultiplexer”.

Typically, Multiplexer and Deultiplexer (Mux and Demux) are integrated in a entirety. CWDM Mux/Demux modules have 2/4/8/16/18 channels commonly, while 5/9 channels uncommonly. In FiberStore, we supply all channel CWDM Mux and Demux. Three single fiber or dual fiber connection for CWDM Mux/Demux are available. Our standard CWDM Mux/Demux package types are Plastic ABS module cassette, 19″ rack mountable box or LGX box. No matter what kind of connectors, like FC, ST, SC, LC, etc., all are available here, and we can also mix connectors on one device.

To know more about the CWDM Mux products, let me introduce one of the CWDM Mux/Demux modules to you. Here is a 18 Channels CWDM Mux and Demux by dual fiber with LGX Metal Box.
