8Ch Lower Band CWDM Mux 1271-1451nm, duplex traffic 2 fibers - LCMX-8-LB2745-LU

Lightem 8Ch Lower Band CWDM Mux is designed to multiplex 8Ch CWDM 1271-1451nm (skip 1391 & 1411nm)into two fibers. It is designed to use with LCMX-8-LB2943 muxes for CWDM upgrade through the existing traffic, but without any interruption of existing services. 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.
