Overview
The Ubiquiti UC-DAC-SFP28 is a UniFi SFP28 Direct Attach Copper cable designed for short-distance high-speed network connections. It uses SFP28 connectors at both ends and supports data rates up to 25 Gbps.
25G SFP28 Connectivity
This passive copper DAC provides a direct SFP28-to-SFP28 connection without requiring separate optical transceiver modules. Its 0.5 m length is suited to short interconnections between compatible network devices, including switch-to-switch links within the same rack or equipment area.
Compatibility and Operation
The UC-DAC-SFP28 is designed for SFP28 interfaces and supports up to 25 Gbps operation. Ubiquiti also identifies this model as backward compatible with SFP+ ports, allowing supported equipment to operate at lower compatible link speeds.
Key Features
- 25 Gbps maximum data rate
- SFP28-to-SFP28 direct connection
- 0.5 m cable length
- Passive copper DAC construction
- 30 AWG cable construction
Applications
The UC-DAC-SFP28 is intended for short high-speed connections between network devices equipped with compatible SFP28 interfaces. Its compact 0.5 m length is particularly suited to rack and equipment-room interconnections.
DC Supplies Product Note
The UC-DAC-SFP28 is the older Ubiquiti model designation for a 0.5 m 25G SFP28 direct attach copper cable. Ubiquiti's current 25G DAC product family uses the UACC-DAC-SFP28 designation with selectable lengths, so the exact UC-DAC-SFP28 MPN should be retained when matching an existing installation or replacement requirement.
