Passive Multiplexers
A passive multiplexer or passive mux is used to combine or multiplex the wavelength onto a fiber. Similarly, on the other end of the connection, a demux or demultiplexer will split the connection. Here, at VCHUNG, you will find a wide array of mux/demux and optical add-drop multiplexers (OADM).
CWDM (coarse wavelength division multiplexing) multiplexers operate between 1270nm and 1610nm, but you can find other types like multi-fiber DWDM, WDM, add and drop, and others.
