Wave Division Multiplexer Ubiquiti UACC-CWDM-8 Width 442 mm Depth 120 mm Height 43.7 mm

The Ubiquiti UACC-CWDM-8 is a rack-mountable 8-channel CWDM mux/demux for wavelengths 1450–1590 nm, designed to increase the capacity of existing fiber infrastructure by combining or separating optical channels over a single fiber. It has a compact 19"-compatible form factor with dimensions 442 mm (W) × 120 mm (D) × 43.7 mm (H) and a lightweight construction (1.4 kg), suitable for installations where space and efficient fiber utilization are important.

Advantages

This CWDM multiplexer provides eight-channel multiplexing and demultiplexing in the 1450–1590 nm range, enabling more efficient use of single-mode fiber without changing active equipment. The rack-mountable design fits standard equipment racks, and the compact footprint helps conserve chassis space. Its passive optical design requires no power, reducing operational complexity and maintenance.

Suitable for

• Expanding capacity of existing single-mode fiber links
• Metro and access networks requiring additional channels without new fibers
• Rack-based telecom or data center installations

Key specifications

• Manufacturer: UBIQUITI
• Model / MPN: UACC-CWDM-8
• Channels: 8 CWDM channels
• Wavelength range: 1450–1590 nm
• Form factor: Rack-mountable (19")

How to use

Install the unit in a standard 19" rack using the provided mounting brackets. Connect the input fiber carrying multiple CWDM wavelengths to the MUX port to combine signals, or connect individual channel fibers to the DEMUX ports to separate wavelengths. Ensure proper fiber connectors and compatible passive components are used. As a passive device, it requires no power supply; handle optical ports with dust caps when not in use and follow standard fiber safety procedures.

Recommendations

Use the UACC-CWDM-8 to add channels to existing single-mode links where additional capacity is needed without laying new fiber. Verify channel allocations and link budget for each wavelength, and use certified connectors and clean fiber practices to maintain signal quality.
