BlueOptics Q28-AOC-50M-FR-BO InfiniBand fibre optic cable 50m QSFP28 Male/Male

The BlueOptics Q28-AOC-50M-FR-BO InfiniBand fibre optic cable is a 50-metre active optical cable designed for high-speed server, storage and switch interconnects. Equipped with QSFP28 male connectors at both ends, it supports high-bandwidth links in data centres and high-performance computing clusters where low latency and stable throughput are required. The cable combines optical transmission with a flexible jacket for organised routing across racks and between equipment.

Advantages

This 50m InfiniBand AOC provides full-duplex high-speed connectivity with reduced electromagnetic interference compared to copper alternatives, supporting long-distance links inside facilities. Its QSFP28 male/male interface is compatible with modern 100Gbps QSFP28 ports and allows simple, tool-free installation. The cable’s optical nature offers consistent signal quality and greater immunity to crosstalk in dense cabling environments.

Suitable for

• Interconnecting servers and switches in data centres
• High-performance computing (HPC) clusters and distributed compute nodes
• Storage area networks (SANs) and high-throughput storage arrays
• Top-of-rack and end-of-row deployments requiring 50 m cable runs

Key specifications

• Cable type: Active optical cable (AOC)
• Connector type: QSFP28 male to QSFP28 male
• Length: 50 metres
• Application: InfiniBand / high-speed data interconnects
• Bandwidth: supports 100 Gbps class QSFP28 links (per industry QSFP28 performance)
• Signal: optical, full duplex
• Jacket: flexible optical cable jacket for rack routing

How to use

Insert each QSFP28 male connector into compatible QSFP28 ports on your switches, NICs or storage devices until the connector latch engages. Route the cable avoiding tight bends and sharp edges; maintain the manufacturer’s minimum bend radius to preserve optical performance. Ensure both ends are seated and the host ports are configured for InfiniBand or corresponding 100Gbps operation. For initial deployment, verify link status and throughput using the device management interface or monitoring tools.

Recommendations

For reliable long-term operation, avoid repeated connector disconnects, keep dust caps on when connectors are not in use, and manage cable bundles to prevent strain. Use the 50 m length for runs that exceed passive copper reach but remain within your data centre’s planned topology. Verify compatibility with QSFP28 ports and firmware requirements on network equipment before installation.
