The GLOBALfiber 150GHz 8-channel DWDM MUX/DEMUX is a passive optical multiplexing solution designed for high-capacity fiber networks. The units operates across the C-band wavelength range (1566.314 nm – 1529,16 nm) and follows the ITU-T 150 GHz DWDM grid, enabling efficient use of existing fiber infrastructure.
Using thin film filter (TFF) technology, the device provides stable wavelength performance, low insertion loss, and strong channel isolation. This makes it ideal for DWDM transport systems supporting up to 8 wavelengths, with capacity scaling for high-speed services such as 100G, 200G, 400G and 800G optical links.
The integrated monitor port allows real-time optical power monitoring and troubleshooting without interrupting live traffic. An EXP (expansion) port enables simple network scaling by connecting additional DWDM multiplexers.
This passive device requires no power supply, making it highly reliable for telecom networks, metro transport, broadband infrastructure, and data center interconnect (DCI) deployments.
