8CH Ultra Compact LWDM Module
Single Fiber LAN-WDM Mux Demux is usually used for 5G fronthaul network where wavelengths are packed tightly together over the O-band, up to 8 wavelengths in 800GHz grid (4.5nm). Based on Thin-Film-Filter (TFF), this LAN-WDM Mux Demux features small form factor, ultra-low insertion loss, high channel isolation, and unparallel reliability.
