CWDM MUX/DeMUX

C-LIGHT CWDM MUX/DeMUX (Coarse Wavelength Division Multiplexer/Demultiplexer) is a cost-effective solution for fiber network capacity expansion. By multiplexing 18 wavelengths (20nm spacing, 1270~1610nm range) onto a single fiber, it enables multi-service transmission over medium to short-haul distances (<80km). With advantages such as low power consumption, simplified deployment, and reduced equipment costs, it is widely used in enterprise network interconnection, data center aggregation, and 5G fronthaul. Particularly suited for small-to-medium networks with limited fiber resources and cost sensitivity, CWDM enhances capacity while significantly lowering deployment and operational complexity.
