Fibre optic InfiniBand cable BlueOptics QSFP56–QSFP56 5 m, orange

BlueOptics QSFP56–QSFP56 fibre optic cable, 5 m length with an orange jacket, is an active optical cable (AOC) designed for short-range InfiniBand and Ethernet interconnects in data center and high-performance computing environments. The assembly features QSFP56 male connectors on both ends and is intended for direct rack- or chassis-level connections between servers, switches and storage systems that accept QSFP56 interfaces. The lightweight construction (0.23 kg) and standardized connector form factor enable straightforward installation in dense networking setups.

Advantages

This BlueOptics AOC provides high aggregate bandwidth up to 200 Gbit/s in short-reach multimode links while maintaining compatibility with systems that support QSFP56 connections. The integrated transmitter and receiver electronics on each end convert electrical signals to optical and back, reducing the need for separate transceivers and simplifying cabling. The orange jacket improves visibility and routing identification in crowded racks, and the 5 m length balances reach and signal integrity for typical top-of-rack and adjacent-rack connections.

How to use

Ensure both devices have compatible QSFP56 interfaces and support the targeted protocol (InfiniBand or 200G Ethernet). Power down or follow hot-plug precautions as required by your hardware vendor, then insert the QSFP56 connectors firmly into the corresponding ports until the latch engages. Route the 5 m cable to avoid tight bends and mechanical strain; maintain the manufacturer’s minimum bend radius for multimode fiber. After connection, verify link status and negotiated speed through the switch or host management interface and check for any required firmware or configuration settings to enable the desired link mode.

Recommendations

Use this BlueOptics QSFP56–QSFP56 AOC for short-distance, high-throughput connections inside racks or between adjacent racks. Keep the cable free from sharp bends and excessive pulling, store spare cables in a looped manner without kinks, and confirm device compatibility and supported link modes before deployment to ensure reliable 200G performance.
