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

The BlueOptics QSFP-AOC-3M-CP-BO InfiniBand fibre optic cable 3m Male/Male is a 3-metre active optical cable with QSFP connectors on both ends, engineered for high-throughput, low-latency links in data center and networking environments. This cable supports InfiniBand protocols and is intended for short-reach interconnects between switches, servers and storage nodes where reliable, high-bandwidth transmission is required. The design reduces electrical-to-optical conversion points compared with discrete transceiver-plus-fibre solutions, simplifying rack connectivity and saving power in dense installations.

Advantages

The cable delivers high data rates with minimal signal loss across its 3 m length and maintains consistent performance in high-density racks. As an active optical cable, it integrates optical transceivers in the cable assembly, providing plug-and-play deployment with QSFP ports while reducing heat and power draw compared with equivalent copper solutions. Its fixed-length design eliminates the need for separate transceiver purchases and cable matching, offering a compact, space-efficient connection that is immune to electromagnetic interference.

Suitable for

• High-performance computing clusters using InfiniBand interconnects
• Data centre spine and leaf switch connections
• Server-to-switch and storage-to-switch short-reach links
• Dense rack environments requiring low-latency, high-bandwidth cabling

Key specifications

• Cable type: Active optical cable (AOC)
• Connector type: QSFP (male) on both ends
• Nominal length: 3 metres
• Supported protocol: InfiniBand
• Typical application: Short-reach high-bandwidth interconnects
• Immunity: Not affected by electromagnetic interference

How to use

Insert each QSFP connector firmly into compatible QSFP ports on your networking equipment. Ensure both host interfaces support InfiniBand and are powered down or follow hot-plug safety guidance from the equipment manufacturer when connecting or disconnecting. No additional transceivers or patch cords are required; the AOC contains integrated optics and is recognized by most systems as a direct QSFP link. Route the cable to avoid sharp bends and allow gentle curves with a radius larger than the cable’s minimum bend specification to prevent damage.

Usage recommendations

For reliable operation, use this 3 m BlueOptics AOC in short-reach links inside racks or between adjacent racks, avoid tight cable bundles that exceed bend limits, and verify compatibility with your switch or host firmware for QSFP AOC support. Keep connectors clean and protected when not in use to preserve optical performance.
