GLOBALfiber 40-Channel DWDM Mux/Demux (C21–C60, 100GHz, 1310nm + Monitor Port, 19” 1RU)
The GLOBALfiber 40-channel DWDM Mux/Demux is a passive wavelength-division multiplexing unit optimized for high-capacity optical transport. It operates across the ITU-T G.694.1 100GHz DWDM grid, covering channels C21 to C60, and is designed to maximize spectral efficiency in the C-band. With low insertion loss and integrated 1310nm legacy support, this unit is ideal for point-to-point long-haul, metro, and data center interconnect applications.
Engineered for reliability, flexibility, and minimal maintenance, the solution can be deployed alongside optical amplifiers and dispersion compensation modules (DCM) to support extended transmission distances.
