BlueOptics Q28-AOC-2M-SP-BO InfiniBand fibre optic cable 2m QSFP28 Male/Male

The BlueOptics Q28-AOC-2M-SP-BO InfiniBand fibre optic cable is a 2-metre active optical cable with QSFP28 male-to-male connectors designed for high-speed interconnects in data centres and high-performance computing environments. It supports the bandwidth and low-latency requirements of modern InfiniBand fabrics, providing a compact, flexible connection between switches, servers and storage nodes. The cable construction ensures signal integrity across the full 2 m length while offering the plug-and-play convenience of QSFP28 interfaces.

Advantages

This active optical cable delivers high data throughput and low latency suitable for demanding networking tasks. Its QSFP28 male connectors provide a standardised interface for compatibility with InfiniBand equipment and QSFP28 ports. The 2 m length balances reach and cable management, reducing clutter and easing routing in rack environments. The optical design minimises electromagnetic interference and heat generation compared with equivalent copper links.

Suitable for

• High-performance computing clusters requiring low-latency links
• Data centre switch-to-switch and switch-to-server interconnects
• Storage area networks and high-bandwidth storage servers
• System expansions where compact, short-reach optical links are preferred

Key specifications

• Cable type: Active optical cable (AOC)
• Connector type: QSFP28 male to QSFP28 male
• Length: 2 metres
• Interface standard: InfiniBand-compatible QSFP28 connectivity
• Performance: Designed for high-bandwidth, low-latency data transfer
• Construction: Optical fibre core with ruggedised outer jacket for data centre use

How to use

Insert the QSFP28 male connectors into compatible QSFP28 ports on switches, servers or storage devices, ensuring connectors are aligned with the port keying to avoid damage. Confirm that connected devices support InfiniBand over QSFP28 and power on systems in accordance with equipment guidelines. For hot-plug capable systems, the cable can be connected or disconnected while equipment is running; follow your hardware vendor’s instructions for safe hot-plug operations.

Recommendations

Route the cable with gentle bends and avoid tight radii to preserve optical performance. Keep the cable away from sharp edges and high-heat sources. Use proper port dust caps when not in use and verify firmware or driver compatibility on network devices to ensure optimal performance.
