Ubiquiti CWDM Mux Demux 8 (UACC-CWDM-8) – Rack-Mount 8-Channel CWDM Multiplexer with Expansion Port

The Ubiquiti CWDM Mux Demux 8 (UACC-CWDM-8) is a professional-grade 8-channel CWDM (Coarse Wavelength Division Multiplexing) multiplexer/demultiplexer engineered to significantly expand the capacity of your existing single-mode fiber infrastructure. By combining eight independent optical wavelengths onto a single fiber pair — and offering an expansion port to scale beyond that — this passive optical device delivers a powerful and cost-efficient solution for modern high-bandwidth network deployments.

Housed in a compact 1U rack-mount SGCC steel enclosure, the CWDM Mux Demux 8 features eight 1450–1590 nm channel ports, a duplex LC UPC communication port for pairing with a second unit, a dedicated monitor port, and a unique expansion port that allows direct linking to a CWDM Mux Demux 4 (UACC-CWDM-4) to add more channels as your network grows.
