Ubiquiti UACC-DAC-QSFP28-3M QSFP28 Direct Attach Cable
Overview
The UACC-DAC-QSFP28-3M is a passive direct attach copper (DAC) cable rated for 100 Gbps between QSFP28 ports. At 3 meters, it bridges equipment within standard rack and adjacent-rack distances without requiring active transceivers or SFP modules — cutting transceiver cost and eliminating another point of failure in high-speed interconnects. Deploy this when you have QSFP28-equipped infrastructure (switches, routers, adapters) in close proximity and want native copper connectivity at wire speed.
Compatibility
Works with any QSFP28-equipped network infrastructure supporting 100GBase-CR4 standard. Verify QSFP28 port availability on your target switches, routers, and network adapters before ordering. The cable connects QSFP28 to QSFP28; confirm both endpoints support this form factor and signaling standard.
Installation Notes
3-meter length suits equipment-to-equipment links within standard data center rack topologies and inter-rack connections. Black jacket. No transceiver modules, modules, or external adapters required — plug directly into QSFP28 ports. Verify cable routing and bend radius compliance during installation; tight loops can degrade signal integrity.
