4Ch CWDM Mux 1470-1610nm, duplex traffic 1 fiber, L3 module package - LCBMX-4AB

Lightem 4Ch CWDM Bidi Mux is designed to multiplex 8Ch CWDM (or 4Ch Full Duplex Traffic) 1470-1610nm duplex traffic into one fiber. It is designed to use with A&B Bidi Muxes together to realised 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 accomodate up to 3 modules. Together with our CWDM Transceiver, the bandwidth of the fiber can be utilized in a cost effective way.
