BlueOptics Q28-AOC-1M-SW-BO InfiniBand/fibre optic cable 1m QSFP28 Male/Male

The BlueOptics Q28-AOC-1M-SW-BO InfiniBand/fibre optic cable 1m QSFP28 Male/Male is a 1-metre active optical cable engineered for high-throughput links in data centres and HPC racks. With QSFP28 male connectors at both ends, this cable supports high-speed serial lanes common to InfiniBand and 100GbE interconnects, offering low latency and electrical isolation compared with copper alternatives. Its compact, factory-terminated design simplifies rack-to-rack and switch-to-server connections where short, reliable optical links are required.

Advantages

This QSFP28 AOC delivers stable high-bandwidth transmission with minimal signal degradation over a 1 m reach. As an optical solution, it eliminates electromagnetic interference and reduces heat dissipation within densely populated enclosures. The pre-terminated QSFP28 male/male form factor enables tool-free installation and predictable performance without field termination. The cable is suitable for hot-pluggable environments and maintains consistent link quality under sustained load.

Suitable for (tasks / use cases)

• Short-reach interconnects between switches and servers in data centres
• High-performance computing clusters requiring InfiniBand connectivity
• 100GbE or similar high-bandwidth uplinks and cross-connects
• Environments where EMI immunity and electrical isolation are needed

Key specifications

• Cable type: Active optical cable (AOC)
• Connector type: QSFP28 male to QSFP28 male
• Length: 1 metre
• Supported interfaces: InfiniBand and 100 Gigabit Ethernet compatible signalling
• Performance: Designed for high-bandwidth, low-latency links over short distances
• Construction: Factory-terminated optical assembly for plug-and-play use

How to use

Install the BlueOptics QSFP28 AOC by inserting each QSFP28 male connector into compatible QSFP28 ports on network switches, adapters or servers. Ensure both devices are powered and their ports are enabled in system firmware or operating system settings. No special tools or on-site fibre termination are required. For best results, verify link speed and lane configuration in the connected equipment and confirm that firmware and drivers support the chosen link protocol (InfiniBand or Ethernet).

Recommendations

Route the cable with gentle bends and avoid tight kinks; respect the manufacturer’s minimum bend radius. Keep the connectors clean and covered when not in use to prevent contamination. Use this 1 m AOC for short intra-rack or adjacent-rack connections rather than long-distance runs; for longer spans, select appropriate transceivers and fibre cabling.
