4 Channel DWDM Fiber Mux Demux – Single Fiber (8 Wavelengths)
Product Overview
The 4 Channel DWDM Fiber Mux Demux is a single-fiber, bi-directional DWDM solution designed to transmit 4 independent services using 8 DWDM wavelengths over one optical fiber.
It operates on C25–C28 and C53–C56 wavelengths, following ITU-T G.694.1 (100 GHz grid) standards, maximizing utilization of the C-band spectrum.
This solution is ideal for ISP backbone, data centers, cloud networks, broadcasting, finance, and government networks, where fiber resources are limited and high capacity is required.
