BlueOptics Q28-AOC-3M-MR-BO InfiniBand fibre optic cable 3m QSFP28 Male/Male

The BlueOptics Q28-AOC-3M-MR-BO InfiniBand fibre optic cable 3m QSFP28 Male/Male is a 3-metre active optical cable engineered for high-speed interconnects in data centre and high-performance computing environments. It uses QSFP28 male connectors on both ends to provide a compact, low-latency link for InfiniBand and other compatible 100Gbps-class interfaces. The cable is intended for short-reach, high-bandwidth connections where electromagnetic immunity and signal integrity are required.

Advantages

This active optical cable offers a high data-rate interface with reduced power consumption compared with equivalent electrical copper solutions for similar distances. Its optical construction provides immunity to electromagnetic interference, consistent signal quality over the full 3 m length, and lower heat generation in dense rack deployments. The QSFP28 form factor ensures compatibility with equipment that supports QSFP28 transceivers or ports, enabling straightforward integration into existing network topologies.

Suitable for

• High-performance computing clusters and server interconnects
• Data centre top-of-rack and leaf-spine connectivity
• Low-latency storage area network links and fabric connections
• Short-reach 100 Gbps-class InfiniBand or Ethernet links

Key specifications

• Cable type: Active Optical Cable (AOC)
• Length: 3 metres
• Connector type: QSFP28 male to QSFP28 male
• Supported interface class: InfiniBand and compatible 100 Gbps-class ports
• Transmission medium: Multimode optical fibres integrated in AOC assembly
• Typical use case: Short-reach, high-bandwidth interconnects

How to use

Install the cable by aligning each QSFP28 male connector with the corresponding QSFP28 port on your devices and inserting until the connector latch engages. Ensure both endpoints support the required InfiniBand or 100 Gbps-class interface and that software or firmware settings on connected equipment are configured for the intended link speed and protocol. Avoid sharp bends and do not exceed the minimum bend radius specified by the equipment manufacturer; route the cable through cable management to prevent strain on connectors.

Recommendations

For reliable operation, verify port compatibility and link settings before deployment, keep the cable free from excessive bending and mechanical stress, and use it within controlled data centre environments. If troubleshooting is required, test continuity and link status with supported diagnostics on the connected devices and replace the cable if persistent link errors are present.
