BlueOptics Q28-AOC-2M-SO-BO InfiniBand fibre optic cable 2m QSFP28 Male/Male

The BlueOptics Q28-AOC-2M-SO-BO InfiniBand fibre optic cable 2m QSFP28 Male/Male is a 2-metre active optical cable engineered for high-speed, short-reach interconnects in data centres and high-performance computing environments. With QSFP28 male connectors on both ends, the cable supports InfiniBand protocols and delivers high bandwidth with low latency across a compact, flexible form factor suitable for top-of-rack and adjacent-rack connections.

Advantages

This active optical cable offers high aggregate throughput suitable for modern 100GbE and InfiniBand HDR/EDR links while maintaining low power consumption and electromagnetic immunity. The QSFP28 connectors provide a standardized interface for direct device-to-device links, reducing the need for transceivers and simplifying rack cabling. The 2 m length balances reach and cable management, enabling neat routing without signal loss typical of longer copper alternatives.

Suitable for

• Interconnecting switches and servers within the same rack or adjacent racks
• High-performance computing clusters requiring low-latency links
• Storage area network (SAN) links and server-to-storage connections
• Temporary test setups and lab environments where quick, reliable links are needed

Key specifications

• Cable type: Active optical cable (AOC)
• Connector type: QSFP28 male to QSFP28 male
• Length: 2 metres
• Protocol compatibility: InfiniBand and 100Gb-class links
• Performance: Designed for high bandwidth and low latency short-reach connections
• Form factor: Compact, flexible optical assembly suitable for dense rack deployments

How to use

Insert each QSFP28 connector into the corresponding QSFP28 port on the devices to be connected, ensuring the connector latch engages securely. No separate transceivers are required when connecting compatible QSFP28 ports; the active optical cable handles optical-electrical conversion internally. Route the cable to avoid sharp bends and mechanical stress on the connectors, and ensure adequate airflow around equipment to prevent overheating in dense installations.

Recommendations

For reliable operation, verify device compatibility with QSFP28 AOC links and confirm supported link speeds in device firmware. Use the 2 m length for within-rack or adjacent-rack connections to minimize latency and simplify cable management. Avoid exceeding the cable's bend radius, and handle connectors by the housing to prevent damage to the mating surfaces.
