4 Channel DWDM Fiber Mux Demux

The 4 Channel DWDM Fiber Mux is a single-fiber DWDM transmitting unit designed to combine multiple DWDM wavelengths into one optical fiber.
It supports bi-directional transmission when used with a matching DWDM Demux at the receiving end.
The Mux operates on C25–C28 and C53–C56 wavelengths, compliant with ITU-T G.694.1 (100 GHz grid), ensuring high stability, low loss, and excellent channel isolation.
