Ubiquiti UC-DAC-SFP28 Dac SFP28 Patch Cable

Product Description

The UBIQUITI UC-DAC-SFP28 is a Direct Attach Copper (DAC) cable terminated with SFP28 connectors, designed for short-range, high-speed network connections within data centers, server rooms, and structured cabling environments. DAC cables carry high-bandwidth signals directly over a copper conductor without requiring separate transceivers, reducing both cost and power consumption at the switch port. This cable is a passive, plug-and-play assembly suited for installation by network technicians and IT infrastructure professionals working on UniFi or compatible SFP28-equipped switching platforms.

The UC-DAC-SFP28 is intended for use in rack-to-rack and top-of-rack switching scenarios where SFP28 ports are present. It is well suited for connecting servers, switches, and storage equipment across short distances in both commercial and enterprise network deployments. Its direct attach construction eliminates the need for optical transceivers, making it a practical choice when port density and cable management efficiency are priorities.

Key Features

• Direct Attach Copper construction eliminates the need for separate optical transceivers
• SFP28 form factor connectors on both ends for compatibility with SFP28 switch and server ports
• Passive cable design reduces power draw at the port compared to active optical solutions
• Plug-and-play installation with no additional configuration required
• Sold individually as a single cable assembly

Compatibility

Designed as an OEM-style passive DAC cable for use with SFP28-equipped network switches, servers, and storage devices supporting the SFP28 interface standard.

Installation Notes

Installation is performed by network technicians familiar with SFP28 port handling. Power down or administratively disable the switch port before seating or removing the DAC cable to avoid unexpected link events. Insert the SFP28 connector firmly until the latch clicks, and verify the port negotiates the expected link speed after connection. Minimum bend radius should be observed during cable routing to avoid signal degradation.
