TELECOM / DATACOM SYSTEMS

Lightem 4, 8, 16 CWDM Mux and DemuxLightem CWDM Mux is designed to multiplex multiple CWDM (1270-1610nm) channels into one or two fibers. The common configuration is 4, 8, 16 channels. Available in Standalone, 19" Rack Mount or LGX module packaging. Optional wide band port for existing 1310nm or 1550nm port is available to multiplex with these CWDM Channels, fully utilise with the existing equipments. Together with our CWDM Transceiver series or the wavelength converter series, the bandwidth of the fiber can be utilized in a cost effective way
