Ubiquiti UACC-DAC-SFP28-1M Dac SFP28 Cable 25 Gbps 1M

Product Description

The UBIQUITI UACC-DAC-SFP28-1M is a Direct Attach Copper (DAC) cable terminated with SFP28 connectors on both ends, designed for high-speed 25 Gbps short-reach interconnects in data center and network infrastructure environments. The cable measures 1 meter in length and delivers a passive, low-latency copper connection between compatible SFP28 ports. It eliminates the need for separate transceivers and optical fiber on short rack-to-rack or switch-to-server runs. Network technicians and IT infrastructure professionals install this cable as a cost-effective, low-power alternative to active optical solutions at distances of 1 meter or less.

This DAC cable is suited for use in structured cabling environments where SFP28 ports are present on top-of-rack switches, servers, and network appliances operating at 25 Gbps. It is a passive cable assembly, meaning no active components are embedded, which simplifies deployment and reduces power draw. Typical installations include spine-and-leaf data center architectures and high-density server interconnects where short copper runs are preferred over fiber. It ships as a single cable assembly unit.

Key Features

• 25 Gbps data rate over a passive Direct Attach Copper assembly
• SFP28 connectors on both ends for direct port-to-port connection
• 1 meter cable length suited for same-rack or adjacent-rack runs
• No active electronics — lower power consumption compared to active optical cables
• Low-latency copper interconnect eliminates transceiver and fiber overhead

Compatibility

Designed for use with network switches, servers, and appliances equipped with SFP28 ports operating at 25 Gbps. Verify host device compatibility with SFP28 passive DAC cables before installation.

Installation Notes

This cable is installed by network technicians familiar with SFP28 port handling and data center cabling practices. Power down or disable the relevant ports on the host devices before seating the connectors to avoid link errors during insertion. Ensure the SFP28 latch mechanism is fully engaged on both ends before powering the link. Avoid sharp bends or excessive pulling force on the cable assembly, as the integrated connector housing is not field-repairable.
