Ubiquiti Accessories Series · NDAA COMPLIANT
Next-Gen 25Gbps High-Speed Interconnect for Enterprise Rack Stacking
The Ubiquiti UACC-DAC-SFP28 is an NDAA compliant, ultra-high-performance 25 Gbps Direct Attach Copper (DAC) cable engineered for short-distance, multi-gigabit interconnectivity within enterprise data centers, government server rooms, and high-density network racks. Measuring 0.5 meters, 1m and 3m this passive SFP28 to SFP28 twinax cable provides an energy-efficient, sub-nanosecond latency alternative to optical transceivers when connecting adjacent UniFi Enterprise switches, high-speed gateways, and enterprise storage arrays.

Passive Twinax Copper
Hot-Swappable Plug-and-Play Integration & Maximum Thermal Efficiency
Designed to eliminate optical conversion overhead while drastically reducing system power consumption, the UACC-DAC-SFP28 features factory-terminated SFP28 connector assemblies on both ends for instant plug-and-play operation. Its highly flexible twinax copper core enables tight bend radii inside crowded 19-inch equipment racks, making it the ideal patch solution for high-throughput backbone links, core aggregation switches, and server uplinks.
Ultra-Short 25G In-Rack Stacking
Optimized 0.5, 1m,3-meter physical length prevents cable clutter and maximizes airflow across dense switch chassis, ensuring clean 25Gbps connectivity between vertically adjacent devices.
Zero Power Draw Passive Design
Operates passively without active processing components, consuming zero additional power compared to optical transceivers and keeping overall cabinet thermal output to a minimum.

Is the Ubiquiti UACC-DAC-SFP28 NDAA compliant?
Yes, as a passive copper interconnect containing no microcontrollers or prohibited vendor hardware, it fully satisfies NDAA Section 889 requirements for government and enterprise deployments.
Is the UACC-DAC-SFP28-0.5M,1M, 3M backward compatible with 10Gbps SFP+ ports?
Yes, SFP28 connectors share the same physical form factor as SFP+ ports and can operate at 10Gbps if supported and configured on the switch hardware.
What is the latency advantage of 25G DAC twinax over fiber transceivers?
Direct Attach Copper (DAC) cables process transmission signals passively without needing optical-to-electrical conversions, offering sub-nanosecond latency ideal for high-throughput server and switch links.
Does this 25G cable require separate SFP28 transceiver modules?
No, the SFP28 connectors are permanently integrated onto each end of the twinax copper cable for seamless, hot-swappable plug-and-play installation.
