The 4-channel LAN-WDM DWDM mux/demux is a passive LWDM device based on thin-film filter (TFF) technology, featuring high density and low loss. An integrated monitor port facilitates troubleshooting without service interruption. The unit works as both multiplexer and demultiplexer, combining 4 LWDM wavelength channels into one composite signal or splitting a composite LWDM signal into 4 separate channels over a pair of single-mode fibers. ITU-T compliant, maximizing C-band bandwidth. Designed for short distances (≤40km), suitable for scalable 5G fronthaul deployment.
