GLOBALfiber 8-Channel O-Band DWDM Mux/Demux (G-OMUX-8LB-LU)
The GLOBALfiber 8-Channel O-Band DWDM Mux/Demux (Part No. G-OMUX-8LB-LU) is a high-performance passive optical module designed for O-Band transmission (228.4–229.8 THz / ~1304–1312 nm) using a 200 GHz ITU grid. This LGX-style plug-in unit enables eight independent DWDM wavelengths over a singlemode fiber pair, offering ultra-low insertion loss, high channel isolation and excellent long-term stability.
Optimized for data centers, enterprise networks, cloud service providers, broadcast distribution and government infrastructure, the module uses advanced Thin Film Filter (TFF) technology and SMF-28e fiber to ensure consistent optical performance across a wide temperature range. Its robust steel housing allows for reliable deployment in splice closures, equipment racks and compact optical nodes.
