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

The BlueOptics Q28-AOC-30M-SW-BO InfiniBand fibre optic cable 30m QSFP28 Male/Male is an active optical cable intended for high-speed interconnects in data centers and high-performance computing environments. With a 30-metre length and QSFP28 male connectors at both ends, this cable supports reliable, low-latency data transmission between compatible InfiniBand or QSFP28 interfaces. It is designed to deliver stable signal integrity over longer reach than copper direct-attach solutions while reducing electromagnetic interference and cabling bulk.

Advantages

This 30m QSFP28 AOC provides a lightweight, flexible alternative to copper cabling, offering improved thermal performance and reduced rack congestion. Active optical technology ensures consistent high-bandwidth throughput and longer effective reach compared with passive copper cables. QSFP28 male-to-male termination simplifies direct connections between QSFP28 ports without additional transceivers, enabling straightforward deployment in server, switch and storage fabrics.

Suitable for

• Interconnects between QSFP28 ports in switches and routers
• High-performance computing clusters requiring InfiniBand links
• Data centre top-of-rack and leaf-spine cabling where 30 m reach is needed
• Server-to-switch or switch-to-switch connections demanding low latency

Key specifications

• Connector type: QSFP28 male to QSFP28 male
• Cable type: Active Optical Cable (AOC)
• Length: 30 metres
• Application: InfiniBand / high-speed data interconnects
• Signal characteristics: designed for high-bandwidth, low-latency transmission

How to use

Verify that both devices support QSFP28 interfaces and that firmware or driver compatibility is met. Power down or follow hot-plug guidelines of your hardware if required, then insert each QSFP28 male connector firmly into the corresponding port until it latches. Route the cable to avoid sharp bends and mechanical stress; maintain minimum bend radius specified by the manufacturer. Monitor link status through device LEDs or management software to confirm an active connection.

Recommendations

For reliable operation, avoid tight bends and kinks, keep the cable away from high-heat sources, and ensure adequate airflow around rack equipment. Use compatible QSFP28 ports and consult device documentation for lane configuration and firmware requirements to achieve expected performance.
