BlueOptics Q28-AOC-30M-IA-BO InfiniBand Fibre Optic Cable 30m QSFP28 Male

The BlueOptics Q28-AOC-30M-IA-BO InfiniBand fibre optic cable 30m QSFP28 Male is a 30-metre active optical cable built for high-speed, low-latency connections in data centres and high-performance computing infrastructures. Equipped with QSFP28 male connectors at both ends, this cable supports the bandwidth and signal integrity required for InfiniBand environments and provides a single-cable solution for short- to mid-range interconnects between switches, servers and storage systems.

Advantages

This active optical cable delivers high data throughput with reduced electromagnetic interference compared to copper alternatives, enabling stable long-distance signalling over 30 metres. The QSFP28 connector format ensures compatibility with InfiniBand QSFP28 ports and supports dense rack cabling thanks to its compact form factor. Built for efficiency, the cable reduces the need for separate transceivers and simplifies deployment while offering consistent optical performance suitable for continuous operation in rack and aisle environments.

Suitable for

• Interconnects between servers and switches in data centres
• High-performance computing clusters and compute nodes
• Storage area network (SAN) connections and aggregation links
• Top-of-rack and end-of-row cabling in dense server racks

Key specifications

• Cable type: active optical cable (AOC)
• Length: 30 metres
• Connector type: QSFP28 male to QSFP28 male
• Protocol compatibility: InfiniBand
• Performance: designed for high-speed, low-latency data transmission
• Construction: optical fibre core with protective jacket suitable for data centre routing

How to use

Connect each QSFP28 male connector to the corresponding QSFP28 ports on your networking devices, ensuring connectors are aligned and fully inserted. No external transceivers are required; the cable integrates optical transceivers within its QSFP28 ends. Route the cable carefully through rack channels or cable management arms to avoid sharp bends and excessive tension. Verify link status on connected devices and configure network settings according to your InfiniBand topology and switch/router documentation.

Recommendations

For optimal performance, avoid tight bending radii and protect connectors from dust when not in use. Use proper cable management to maintain airflow and reduce stress on ports. Confirm firmware and port compatibility on switches and host adapters before deployment to ensure full bandwidth and expected latency characteristics.
