BlueOptics Q28-AOC-3M-HU-BO InfiniBand fibre optic cable 3m QSFP28 Male

The BlueOptics Q28-AOC-3M-HU-BO InfiniBand fibre optic cable 3m QSFP28 Male is a 3-metre active optical cable engineered for high-speed InfiniBand connections. Featuring QSFP28 male connectors on both ends, this cable supports short-reach, high-bandwidth links commonly required in data centres, high-performance computing clusters and enterprise networking racks. The single, compact assembly provides a lower-latency alternative to copper for short interconnects while simplifying cabling with a fixed-length, plug-and-play form factor.

Advantages

This QSFP28 active optical cable delivers high data throughput and consistent signal integrity over a 3 m span. The optical construction reduces electromagnetic interference and heat generation compared with equivalent copper alternatives. Its QSFP28 male-to-male connectors ensure compatibility with standard InfiniBand QSFP28 ports, enabling straightforward installation and reliable mating. The pre-terminated design eliminates field termination and supports a tidy rack appearance with predictable performance.

Suitable for

• Short-reach server-to-switch or switch-to-switch interconnects in data centres
• High-performance computing (HPC) cluster node links
• Storage area network (SAN) connections requiring low latency
• Enterprise rack cabling where QSFP28 InfiniBand ports are used

Key specifications

• Connector type: QSFP28 male on both ends
• Length: 3 metres
• Medium: active optical cable (AOC)
• Application: InfiniBand high-speed data links
• Typical advantages: low latency, high bandwidth, EMI immunity

How to use

Ensure both equipment ports support QSFP28 InfiniBand connections and are powered down or hot-plug ready according to the device manufacturer’s instructions. Align the QSFP28 plug with the port and insert until the connector latches. Verify the link status on connected devices and confirm negotiated speed and link health via system management interfaces. For removal, release the latch and withdraw the connector straight out to avoid stressing the cable.

Recommendations

Route the cable with gentle bends and avoid tight loops; maintain the manufacturer’s minimum bend radius to protect the optical fibres. Do not stretch or crush the cable and avoid exposure to extreme temperatures or liquids. For inventory and replacement planning, use the fixed 3 m length to design consistent rack layouts and spare stock.
