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

The BlueOptics Q28-AOC-30M-FR-BO InfiniBand fibre optic cable 30m QSFP28 Male is a 30-metre active optical cable engineered for high-throughput interconnects. It uses QSFP28 male connectors to support InfiniBand links and high-speed server, switch and storage connections. The cable is intended for data centre and high-performance computing environments where stable, low-latency transmission and immunity to electromagnetic interference are required.

Advantages

This active optical cable delivers high bandwidth and low latency suitable for InfiniBand deployments while maintaining reduced power consumption compared with some electrical copper alternatives. Its 30 m length covers longer rack-to-rack distances without additional transceivers, and the optical design reduces signal attenuation over that span. The QSFP28 connector format ensures compatibility with equipment that accepts QSFP28 interfaces and supports multi-lane, high-speed links.

Suitable for

• Rack-to-rack connections in data centres
• High-performance computing clusters and server interconnects
• Switch-to-switch or switch-to-server high-bandwidth links
• Environments requiring immunity to EMI and reduced cabling weight

Key specifications

• Length: 30 metres
• Connector type: QSFP28 male
• Cable type: Active optical cable (AOC)
• Application: InfiniBand high-speed links
• Transmission: Multi-lane high-bandwidth optical transmission with low latency
• Operating environment: Designed for data centre and HPC installations

How to use

Connect each QSFP28 male connector to the corresponding QSFP28 port on switches, servers or host channel adapters. Ensure both ends are securely seated and that the equipment supports InfiniBand over QSFP28 interfaces. Route the cable to avoid sharp bends and mechanical stress; follow rack and cable management practices to maintain airflow and prevent strain on connectors. No additional transceivers are required for standard QSFP28 ports when using this AOC.

Recommendations

Inspect connector ferrules before installation and keep dust caps in place until final connection. Avoid bending the cable beyond manufacturer-specified bend radii and protect it from repeated flexing. For optimal performance, use with compatible InfiniBand-capable hardware and verify link negotiation and firmware compatibility when integrating into existing networks.
