Ubiquiti UACC-DAC-QSFP28-3M – 100G QSFP28 Direct Attach Cable 3M
Overview
The Ubiquiti UACC-DAC-QSFP28-3M is a 3-meter 100G direct attach copper cable with QSFP28 connectors on both ends. It supports 100 Gbps and 40 Gbps data rates and is designed for direct interconnection between compatible QSFP28 and QSFP+ interfaces.
The cable provides a short, pre-terminated copper connection for high-bandwidth switch, server, and storage interconnects. Its 3-meter length is suited to same-rack and short adjacent-rack connections where an optical transceiver and separate fiber cable are not required.
Technical Information
The cable uses 30 AWG copper wire with a black PVC jacket. Ubiquiti specifies a jacket outer diameter of 8.9 mm for the 3-meter version and a minimum bend radius of 47 mm. The supported data rates are 100 Gbps and 40 Gbps.
The cable operates from 0 to 70°C and has a maximum power consumption specification of 2.5W. The QSFP28-to-QSFP28 connector configuration allows direct connection to compatible QSFP28 ports while also supporting QSFP+ interfaces at 40 Gbps.
Compatibility
UACC-DAC-QSFP28-3M is compatible with QSFP28 and QSFP+ interfaces supporting the cable's specified 100 Gbps or 40 Gbps data rates. Verify that the connected network equipment supports the required interface type, speed, and direct-attach cable compatibility before deployment.
This is a passive copper direct attach cable and is intended for short-distance interconnects. It should not be substituted for optical cabling where the required link distance exceeds the practical range of a copper DAC.
Key Features
- 3-meter QSFP28-to-QSFP28 direct attach copper cable.
- Supports 100 Gbps and 40 Gbps data rates.
- Compatible with QSFP28 and QSFP+ interfaces.
- 30 AWG copper wire with black PVC jacket.
- 47 mm minimum bend radius for the 3-meter version.
Applications
The cable is suited to high-speed data-center interconnects between switches, servers, storage systems, and other equipment equipped with compatible QSFP28 or QSFP+ ports. Typical deployments include same-rack connections and short rack-to-rack links.
DC Supplies Product Note
For installation planning, allow at least the specified 47 mm bend radius and account for the 8.9 mm cable jacket diameter. Confirm that both connected devices support the intended 100 Gbps or 40 Gbps operating mode before ordering.
