Ubiquiti UC-DAC-SFP28 UniFi SFP28 Direct Attach Cable - 25GbE, 0.5m

The Ubiquiti UC-DAC-SFP28 is a passive SFP28 Direct Attach Cable engineered for 25GbE network environments, carrying up to 25 Gb/s between switches, servers, and other network devices with male SFP28 connectors at each end. At 0.5m (1.64 ft), this ultra-thin 30 AWG cable handles high-speed short-reach interconnects without the cost or latency overhead of active optical solutions.

For network administrators sourcing a passive DAC cable for UniFi switches or building high-density 25GbE infrastructure, the UC-DAC-SFP28 delivers a low-cost, plug-and-play interconnect solution. Its backward compatibility with SFP+ ports extends its utility across mixed-generation environments, making it a practical choice for deployments where 10GbE and 25GbE equipment coexist on the same network fabric.

Passive direct attach cables eliminate the power draw and signal conversion overhead of active optical transceivers, reducing both operating cost and heat load in dense switch environments. The UC-DAC-SFP28's ultra-thin profile and 30 AWG construction support high-density rack cabling without restricting airflow - a meaningful advantage in structured data center and enterprise network deployments where cable management directly affects thermal performance.

Key Features of the UniFi SFP28 DAC Patch Cable

• 25 Gb/s Data Transfer Rate: Handles full 25GbE throughput between compatible network devices, enabling high-bandwidth server-to-switch and switch-to-switch connections without active components.
• Passive Design: Eliminates the power consumption and heat generation of active optical transceivers, reducing operating costs and simplifying thermal management in high-density rack environments.
• SFP+ Backward Compatible: Works with SFP+ ports in addition to SFP28, protecting the investment in this cable across mixed-generation network infrastructure.
• Ultra-Thin 30 AWG Construction: The 0.17-inch cable diameter supports clean, high-density rack cabling with minimal airflow obstruction compared to standard twinax cables.
• UniFi Ecosystem Integration: Part of Ubiquiti's UACC accessory series, designed to complement UniFi switching platforms for consistent, validated performance within the UniFi network stack.
• Short-Reach Patch Application: The 0.5m length targets within-rack and top-of-rack interconnects where direct attach cabling is the most cost-effective high-speed solution.
