Wave Division Multiplexer Ubiquiti UACC-CWDM-4 Width 442 mm Depth 120 mm Height 43.7 mm

The Ubiquiti UACC-CWDM-4 is a rack-mountable 4-channel CWDM mux/demux operating in the 1270–1330 nm band. With a compact 442 mm × 120 mm × 43.7 mm enclosure, it is designed to increase the capacity of existing fiber infrastructure by combining or separating multiple wavelengths on a single fiber for more efficient bandwidth use.

Advantages

The device provides four-channel coarse wavelength division multiplexing in the 1270–1330 nm range, fits standard racks, and has a compact footprint that supports space-constrained installations. It enables cost-effective capacity expansion of legacy fiber links without laying new fiber and integrates with existing optical equipment.

Suitable for

• Expanding capacity of point-to-point fiber links
• Data center interconnects and campus backbone upgrades
• Telecom and enterprise network wavelength management
• Environments where rack-mounted, space-saving optical multiplexing is required

How to use

Install the unit in a standard 19-inch rack using appropriate mounting hardware. Connect the fiber links to the designated input/output ports, ensuring correct wavelength mapping between connected transceivers and the mux/demux ports. Use the device to combine multiple transmitter wavelengths onto a single fiber for transport, or to separate wavelengths from a single fiber to multiple receivers at the far end.

Recommendations

Ensure compatibility of transceiver wavelengths with the 1270–1330 nm channels, maintain proper fiber cleaning procedures before connections, and follow standard rack grounding and fiber management practices to preserve signal quality and equipment reliability.
