8Ch CWDM Mux 1470-1610nm + 1310nm WB (Upgrade) port, duplex traffic 2 fibers -

Lightem 8+1Ch CWDM Mux is designed to multiplex 8Ch CWDM 1470-1610nm & CWDM Upgrade (1310WB) into two fibers. The CWDM Upgrade (1310WB) port can be used to multiplex lower band CWDM (1270-1450nm) with excellent insertion loss and isolation characteristics. 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.
