BlueOptics Q28-AOC-15M-SO-BO InfiniBand fibre optic cable 15m QSFP28 Male

The BlueOptics Q28-AOC-15M-SO-BO InfiniBand fibre optic cable 15m QSFP28 Male is a 15-metre active optical cable designed to carry high-bandwidth InfiniBand signals between compatible ports. With QSFP28 male connectors on both ends, this cable supports dense server and switch interconnects where low latency and stable throughput are required. The cable is intended for short-reach, high-speed links inside racks and between adjacent racks in data centre and HPC environments.

Advantages

This 15m QSFP28 cable offers high data-rate transmission with electrical-to-optical conversion integrated into the cable assembly, reducing the need for separate transceivers. The active optical design keeps power consumption and heat lower than equivalent electrical copper solutions at similar distances. The pre‑terminated QSFP28 male connectors simplify installation, minimise connector loss and ensure consistent performance across multiple links.

Suitable for

• Top-of-rack and middle-of-row switch-to-switch connections
• Server to switch links in high-performance computing clusters
• Low-latency fabrics and InfiniBand interconnects
• Data centre patching where 15 m reach is required

Key specifications

• Connector type: QSFP28 male to QSFP28 male
• Length: 15 metres
• Cable type: Active optical cable (AOC)
• Supported protocol: InfiniBand (QSFP28 form factor)
• Typical use: Short-reach high-speed interconnects inside racks and between adjacent racks

How to use

Install the cable by firmly inserting each QSFP28 male connector into the corresponding port on your switch or server until the latch engages. Verify that both ends are seated and that ports recognise the link according to your system management tools. Route the cable to avoid sharp bends and excessive tension; maintain the manufacturer’s minimum bend radius to preserve optical performance. For hot-pluggable ports, follow your equipment vendor guidance on safe insertion and removal procedures.

Recommendations

Use this active optical cable for links up to 15 m where QSFP28 InfiniBand connectivity is required. Avoid kinking or tight loops, keep the cable away from high-EMI electrical bundles, and store unused cables in protective reels or bags to prevent contamination of connector endfaces. Confirm compatibility with your switch and server QSFP28 ports and monitor link status after installation.
