16Ch DWDM 100GHz C Band Mux Ch44-59 + 1310nm WB + DWDM Upgrade, duplex traffic 2 fibers - LDMR-1610+2-C4459-LU

Lightem 16Ch DWDM 100GHz C Band Mux is designed to multiplex 16Ch DWDM 100GHz C Band for Ch44-59 duplex traffic into two fibers. The 1310WB port can be used to multiplex CWDM channel (1270-1450nm); where the DWDM Upgrade port can be used to multiplex additional CWDM/DWDM channel 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 accomodate up to 3 modules. Together with our DWDM Transceiver, the bandwidth of the fiber can be utilized in a cost effective way.
