BlueOptics Q28-AOC-30M-GM-BO InfiniBand fibre optic cable 30m QSFP28 Male

The BlueOptics Q28-AOC-30M-GM-BO InfiniBand fibre optic cable 30m QSFP28 Male is a 30-metre active optical cable designed for high-speed InfiniBand connections. It uses QSFP28 male connectors on both ends to provide low-latency, high-throughput links suitable for dense rack and data centre deployments. The cable supports reliable, long-reach connectivity between switches, host adapters and other QSFP28-capable equipment while maintaining signal integrity over its 30 metre length.

Advantages

This active optical cable offers high bandwidth and low latency typical of InfiniBand QSFP28 interconnects, combined with the flexibility and reduced electromagnetic interference of fibre optics. The 30 m length enables cross-rack and row-to-row connections without intermediate transceivers, simplifying installation and reducing point-of-failure components. QSFP28 male terminations provide a standardized electrical and optical interface for modern HPC and data centre hardware.

Suitable for

• High-performance computing clusters and GPU server interconnects
• Data centre switch-to-switch connections across racks
• Storage area networks and high-throughput data paths
• Low-latency trading systems and other latency-sensitive applications

Key specifications

• Cable type: Active optical cable (AOC)
• Connector type: QSFP28 male to QSFP28 male
• Length: 30 metres
• Application: InfiniBand high-speed data links
• Signal medium: Fibre optic
• Typical use environment: Data centres and server rooms

How to use

Connect each QSFP28 male connector to the corresponding QSFP28 ports on your devices, ensuring proper alignment and seating. Verify that connected equipment supports InfiniBand over QSFP28 and that port settings (speed, link training) match expected configurations. Avoid tight bends and protect the cable from sharp edges; follow device-specific guidance for port hot-plugging to prevent system interruptions. After installation, confirm link status and performance through your network management tools.

Recommendations

Handle the fibre optic cable by the connector housings when positioning; maintain minimum bend radius as specified by industry guidelines, and keep the cable away from sources of mechanical stress. Use this 30 m QSFP28 AOC for direct device-to-device links in rack and row topologies where passive copper solutions are impractical due to distance or signal integrity requirements.
