40Ch DWDM C band+ 1310nm WB+ 40Ch DWDM Upgrade 50GHz ready Mux and Demux

Lightem 40Ch AAWG DWDM Mux and Demux are designed to multiplex multiple DWDM channels into two fibers. Available in standalone, 19″ Rack Mount, with options of monitor ports and 1310nm wide band port for existing 1310nm. Together with our 100GHz 40Ch Hband DWDM Mux and 50GHz DWDM Transceiver optics, 80Ch DWDM 50GHz waves are multiplexed into two fiber. The bandwidth of the fiber can be utilized in a cost effective way.
