BlueOptics Q28-AOC-50M-IB-BO InfiniBand-kuitu kaapeli 50m QSFP28 liitin

The BlueOptics Q28-AOC-50M-IB-BO InfiniBand fibre optic cable 50m QSFP28 Male is a 50-metre active optical cable designed for high-bandwidth, low-latency connections in data centre and enterprise networking environments. With QSFP28 male connectors at each end, this cable supports high-speed InfiniBand links and provides a flexible, lightweight alternative to copper for short- to medium-reach connections between switches, servers and storage arrays.

Advantages

This active optical cable delivers stable signal integrity over 50 metres while keeping power consumption and weight lower than equivalent copper assemblies. QSFP28 connectivity enables compatibility with equipment supporting InfiniBand high-speed ports and allows efficient aggregation of lanes for increased throughput. The cable's optical design reduces electromagnetic interference and heat dissipation in dense rack environments, supporting consistent performance under continuous load.

Suitable for

• Interconnects between top-of-rack or leaf switches and spine switches in high-performance networks
• Server-to-switch connections in data centres requiring InfiniBand low-latency links
• Storage system interconnects and high-speed clustering environments
• Short- to medium-reach backbone links where cable weight and EMI immunity are important

Key specifications

• Cable type: active fibre optic (AOC) designed for InfiniBand
• Connector type: QSFP28 male to QSFP28 male
• Length: 50 metres
• Transmission: high-speed multi-lane InfiniBand compatible optical link
• Latency: low transmission latency suitable for HPC and storage traffic
• Physical: lightweight, flexible jacket for data centre cable management
• Immunity: resistant to electromagnetic interference compared to copper alternatives

How to use

Install the cable by aligning and inserting each QSFP28 male connector into the corresponding port until it seats securely. Route the 50m cable through standard cable management paths, avoiding sharp bends and excessive tensile stress to preserve optical performance. No field termination is required; the cable is pre-terminated and ready for plug-and-play operation with compatible InfiniBand QSFP28 ports. Ensure connected devices are powered and configured for matching link speed and lane mapping when establishing the connection.

Recommendations

For reliable operation, verify port compatibility and firmware support on connected devices before deployment. Maintain bend radii recommended by the manufacturer, secure the cable to avoid strain on connectors, and keep connectors dust-free by using protective caps when not in use. In dense installations, consider routing paths that minimise crossovers with high-power electrical cables to simplify maintenance and preserve signal quality.
