## Summary description

The Ubiquiti UACC-CWDM-4 is a wave division multiplexer designed for efficient optical signal management. It features a compact design with dimensions of 442 mm in width, 120 mm in depth, and 43.7 mm in height, making it suitable for various installations. This device enhances network performance by allowing multiple wavelengths to be transmitted over a single fiber optic cable, optimizing bandwidth usage.

## Long description

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
Key specifications
