BlueOptics Q28-AOC-50M-MT-BO InfiniBand Fibre Optic Cable 50m QSFP28 Male

The BlueOptics Q28-AOC-50M-MT-BO InfiniBand fibre optic cable is a 50-metre active optical cable designed for high-density networking and low-latency data transfer. With QSFP28 male connectors at both ends, this cable supports high-speed interconnects commonly used in data centre racks, top-of-rack switches, and high-performance computing clusters. The cable construction and optical transceivers are optimised for reliable signal integrity across the full 50 m length, making it suitable for medium-range connections where copper solutions are impractical.

Advantages

This active optical cable delivers high bandwidth and low latency required by InfiniBand networks while reducing electromagnetic interference and heat dissipation compared with equivalent copper assemblies. The QSFP28 male connector format provides compatibility with a wide range of QSFP28 ports used in modern switches and servers. The 50 m length offers flexibility for rack-to-rack and equipment-to-equipment links without the need for intermediate transceivers or patch panels.

Suitable for

• Rack-to-rack connections in data centres
• Interconnects for high-performance computing (HPC) clusters
• Direct links between QSFP28-enabled switches and servers
• Low-latency storage area network (SAN) links

• Connector type: QSFP28 male to QSFP28 male
• Length: 50 metres
• Protocol compatibility: InfiniBand (QSFP28 form factor)
• Performance: Designed for high-bandwidth, low-latency optical transmission
• Construction: Flexible optical cable jacket suitable for data centre routing

How to use

Ensure both endpoints are powered down or in a safe state for hot-pluggable operations if required by your equipment. Align the QSFP28 male connectors with the device ports and insert until the connector latches. Confirm link status through your switch or host indicators and verify negotiated link speed and health via management interfaces. To remove, disengage any latches and extract the connector straight out to avoid bending the cable near the connector. Follow your equipment vendor guidelines for hot-swap and firmware compatibility.

Recommendations

Use cable management accessories to avoid sharp bends and excessive strain; maintain minimum bend radius as specified by the cable manufacturer. Keep optical connector ends clean and protected when not in use. For reliable long-term operation in dense rack environments, route the cable to minimise crossing hot airflow paths and avoid contact with high-temperature surfaces.
