InfiniBand/fibre optic cable Ubiquiti UACC-DAC-QSFP28-0.5M

The Ubiquiti UACC-DAC-QSFP28-0.5M is a 0.5 meter QSFP28 direct attach cable offering up to 100 Gbps data rate for InfiniBand and fiber-optic network links. It features QSFP28 connectors on both ends and is designed for short-reach, high-bandwidth connections in data centers and high-performance network environments.

Advantages

This direct attach cable provides a compact 0.5 m length for neat rack installations, low latency suitable for HPC and storage clusters, and a 100 Gbps maximum throughput for bandwidth-intensive tasks. The cable's robust construction delivers stable connectivity and reliable performance in dense network setups.

Suitable for

• Data center uplinks and switch-to-switch connections
• High-performance computing (HPC) clusters
• Storage area networks and server interconnects
• Short-reach 100 Gbps links using QSFP28 ports

Key specifications

• Connector type: QSFP28 to QSFP28
• Length: 0.5 m
• Maximum data rate: 100 Gbps
• Brand: UBIQUITI
• Manufacturer part number (MPN): UACC-DAC-QSFP28-0.5M

How to use

Insert each QSFP28 connector into corresponding QSFP28 ports on networking equipment such as switches, NICs, or storage controllers. Ensure connectors are fully seated and that port latch mechanisms engage. Use this cable for short-distance connections inside racks or between adjacent racks where a 0.5 m length is appropriate.

Recommendations

Use in environments with compatible QSFP28 ports and verify device compatibility for direct attach copper or passive/active DACs as required. Avoid sharp bends and excessive mechanical stress; route the cable to prevent kinks and keep within the recommended bend radius for optimal performance.
