BlueOptics QFX-QSFP-AOC-7M-BO InfiniBand fibre optic cable 40 m

The BlueOptics QFX-QSFP-AOC-7M-BO InfiniBand fibre optic cable 40 m is a high-speed active optical cable designed for short- to mid-range interconnects in data centers and high-performance computing environments. Featuring QSFP connectors and a 40-metre length, this cable supports low-latency, high-bandwidth links between switches, servers and storage arrays where reliable InfiniBand connectivity is required.

Advantages

This active optical cable provides high data throughput with minimal signal loss and electromagnetic interference immunity. Its QSFP form-factor connectors enable compact, high-density deployments and straightforward plug-and-play installation. The 40 m length allows flexible rack-to-rack or row-to-row cabling without the need for transceivers or additional fibre termination, reducing component count and simplifying infrastructure.

Suitable for

• Data centre rack-to-rack or row-to-row interconnects
• High-performance computing clusters requiring InfiniBand links
• Server-to-switch and switch-to-switch high-bandwidth connections
• Storage area networks and low-latency fabrics

Key specifications

• Connector type: QSFP (Quad Small Form-factor Pluggable)
• Cable type: Active Optical Cable (AOC)
• Supported protocol: InfiniBand
• Length: 40 metres
• Transmission: High-bandwidth, low-latency optical link
• Interference immunity: Immune to electromagnetic interference typical for optical links

How to use

Install the cable by inserting the QSFP connectors into compatible QSFP ports on network equipment. Ensure both link endpoints support InfiniBand protocol and that ports are configured according to vendor guidelines. Route the cable to avoid sharp bends and mechanical stress; secure with appropriate cable management to maintain bend radius and reduce strain. Active optical cables are hot-pluggable in most systems, but verify system documentation for any hot-swap procedures or required link initialization steps.

Recommendations

Verify port compatibility and firmware requirements on switches and host adapters before installation. Maintain manufacturer-recommended minimum bend radius and avoid kinks. For optimal performance, use clean, undamaged connectors and perform regular visual inspections in high-density installations.
