BlueOptics QSFP-AOC-3M-F5-BO InfiniBand fibre optic cable 3m Male/Male

The BlueOptics QSFP-AOC-3M-F5-BO InfiniBand fibre optic cable 3m Male/Male is a 3-metre active optical cable with QSFP connectors on both ends, engineered for high-speed, low-latency interconnects in data centre and enterprise networking environments. It supports InfiniBand protocol links and is intended for direct device-to-device connections where reliable, high-bandwidth transmission is required. The male-to-male QSFP configuration allows straightforward insertion into compatible QSFP ports without additional transceivers or adapters.

Advantages

This active optical cable delivers consistent high-throughput performance while reducing electromagnetic interference compared with copper alternatives. Its 3 m length provides flexibility for rack-to-rack or within-rack connections without excessive slack. The QSFP form-factor ensures compatibility with a wide range of networking switches, host channel adapters and storage systems that accept QSFP interfaces, offering a compact and efficient solution for InfiniBand links.

Suitable for

• High-performance computing (HPC) clusters and InfiniBand fabrics
• Data centre switch-to-switch and switch-to-server interconnects
• Storage area network (SAN) backbones and server uplinks
• Low-latency trading, scientific computing and machine learning clusters

Key specifications

• Connector type: QSFP male to QSFP male
• Cable type: Active optical cable (AOC)
• Length: 3 metres
• Protocol support: InfiniBand
• Typical use: Short-range, high-bandwidth data interconnects

How to use

Install the cable by aligning each QSFP connector with the device QSFP port and inserting until the connector latches. Ensure both ends are fully seated and device firmware or drivers support the connected InfiniBand links. The cable requires no external power supply beyond the devices it connects. Route the cable to avoid sharp bends and mechanical strain; leave enough slack to permit device servicing and rack movement.

Recommendations

For reliable operation, keep the cable away from sources of excessive heat and avoid bending below the manufacturer-recommended minimum bend radius. Verify compatibility with your QSFP ports and firmware versions before deployment, and document link settings in network management tools to maintain predictable performance.
