Ubiquiti UACC-AOC-QSFP28-30M Long-range QSFP28 Direct Attach Cable
Overview
The UACC-AOC-QSFP28-30M is a 30-meter active optical QSFP28 direct attach cable rated for 100 Gbps throughput. This is the cable you deploy when standard copper DAC runs out of distance — 30 meters of fiber reach with zero transceiver module swaps. Solves the inter-switch backbone problem in data centers where equipment racks sit far enough apart that passive copper fails or introduces unacceptable latency. QSFP28 connectors on both ends plug directly into compatible switch uplinks and network appliances.
Compatibility
Works with any network switch, router, or appliance featuring QSFP28 ports rated for 100 Gbps operation. Ubiquiti USW and EdgeSwitch platforms with QSFP28 support are primary targets, but this is a standards-based connector — verify your third-party equipment supports active optical cables at 100 Gbps before installation. Some older QSFP28 ports may default to lower speeds; firmware updates or port configuration may be required to achieve full 100 Gbps negotiation.
Installation Notes
Active optical cables are more bend-sensitive than passive copper DACs — avoid sharp radius turns and crushing loads during runs through conduit. The 30-meter distance assumes direct fiber path; coiling or tight spirals on excess length reduces effective range slightly. Verify both ends of the connection support 100 Gbps QSFP28 before installation — if one side negotiates at 40 Gbps, the link will operate at 40 Gbps. No additional power injection required; all signaling runs across the QSFP28 connector pins.
