Lightem 8Ch CWDM Bidi Mux is designed to multiplex 16Ch CWDM (or 8Ch Full Duplex Traffic) 1290-1430 & 1470-1610nm duplex traffic into one fiber. It is designed to use with A&B Bidi Muxes together to realized 8Ch full duplex traffic over one fiber. It is packaged in a L3 module (Other package is available upon request); with our 19″ 1U chassis (P/N: L19-3L3), a 1U rack space can accommodate up to 3 modules. Together with our CWDM Transceiver, the bandwidth of the fiber can be utilized in a cost effective way.
