The Ubiquiti UniFi UACC-DAC-SFP28-1M is a high-speed, passive Direct Attach Copper (DAC) twinax cable engineered for short-range, ultra-low latency intra-rack interconnects.

Terminated with dual SFP28 connectors, this cable is purpose-built to sustain true 25 Gbps line rates. It is most frequently used to stack adjacent enterprise aggregation switches or bridge high-capacity servers and Network Attached Storage (NAS) units directly into a top-of-rack layout without the heat, latency, or hardware costs of optical transceivers.
