BlueOptics Q28-AOC-30M-F5-BO InfiniBand fibre optic cable 30m QSFP28 Male

The BlueOptics Q28-AOC-30M-F5-BO InfiniBand fibre optic cable 30m QSFP28 Male is a 30-metre active optical cable designed for high-throughput, low-latency connections in data centre and high-performance computing environments. It uses QSFP28 connectors to support multi-lane serial links and is intended for short-to-medium reach interconnects between switches, servers, and storage systems. The cable supports reliable signal integrity over its full 30 m length while maintaining the physical flexibility and thermal characteristics required for dense rack installations.

Advantages

This active optical cable offers high aggregate bandwidth and low power draw compared with equivalent copper assemblies, while providing immunity to electromagnetic interference. Its QSFP28 form-factor enables easy integration into existing QSFP28 ports and supports multi-lane protocols for backward compatibility. The 30 m length reduces the need for intermediate patch panels in many top-of-rack and end-of-row deployments and simplifies cable management in constrained spaces.

Suitable for

• Interconnecting QSFP28-equipped switches and servers within data centres
• High-performance computing clusters requiring low-latency links
• Storage area network (SAN) backbones and inter-rack connections
• Upgrading network fabrics to support higher aggregate throughput

Key specifications

• Connector type: QSFP28 male on both ends suitable for QSFP28 ports
• Length: 30 metres of active optical cable
• Media: active optical fibre suitable for InfiniBand and high-speed Ethernet
• Signal characteristics: multi-lane serial transmission with low-latency performance
• Physical: flexible cable construction designed for rack routing and dense installations

How to use

Ensure both equipment ports are powered down or that hot-plug procedures recommended by the equipment manufacturer are followed. Insert each QSFP28 connector into the corresponding port until it latches; do not force the connector. Route the cable to avoid sharp bends and maintain the minimum bend radius recommended for optical assemblies. After connection, verify link status and negotiated speed using the host or switch management interface and monitor for any link alarms or errors.

Recommendations

For optimal performance, avoid tight bundling with electrical power cables and secure the cable to maintain gentle curves; inspect connectors for dust and contamination before insertion and use protective caps when the cable is not connected.
