The Ubiquiti UniFi 25G Direct Attach Copper Cable (Model: UACC-DAC-SFP28-3M) is a 3-meter (9.8 ft) passive twinax cable assembly pre-terminated with high-density SFP28 connectors on both ends. Engineered specifically for next-generation 25 Gbps network backbones, it provides high-throughput, short-distance inter-rack connectivity between UniFi Enterprise/Pro Max switches, core aggregation hardware, and high-speed network storage arrays without the cost, complexity, or thermal dissipation of 25G optical transceivers.
Operating passively over multi-lane 30 AWG twinaxial copper wiring, the UACC-DAC-SFP28-3M delivers near-zero latency and ultra-low power consumption (under 0.1 W per end). Fully hot-swappable and natively recognized within the UniFi Network management platform, it features durable die-cast zinc connector housings, integrated strain relief boots, and pull-release latching mechanisms designed for secure, high-density deployment in demanding server rack environments.
Comprehensive Key Features:
25 Gbps High-Bandwidth Throughput: Supports full 25 Gbps bi-directional line rates, providing 2.5x the bandwidth of standard 10G SFP+ links.
Passive Copper Architecture: Delivers ultra-low latency signaling with near-zero power overhead compared to 25G optical SFP28 transceivers.
Factory-Terminated SFP28 Connectors: Pre-assembled with hot-swappable SFP28 modules on both ends for instant plug-and-play installation.
Optimal 3-Meter Reach: Sized for bridging adjacent server racks, connecting patch panel switch stacks, or linking high-density distribution switches.
30 AWG Twinaxial Wiring: High-flexibility 30 AWG copper conductors housed inside a durable PVC jacket to withstand tight rack bends.
Seamless UniFi Integration: Automatically detected and managed within the UniFi Network application for link speed monitoring, topology mapping, and port telemetry.
