Single fiber DWDM Mux should be used in pairs, which transmits and receives different wavelengths into a fiber at the opposite direction. Each channel carries data independently from each other, allowing network designers to transport different data rates. It's protocol and rate transparent supporting such applications as 1G/10G Ethernet, SDH/SONET and 8/4/2/1G Fiber Channel across the same fiber link.
Combined with FS DWDM optical transceivers, optical fiber cables, EDFA, OADM and transponders, etc., it can realize high-density multiplexing, flexible management and expansion of different wavelength optical signals.
