BlueOptics Q28-AOC-30M-QN-BO InfiniBand fibre optic cable 30m QSFP28 Male/Male

The BlueOptics Q28-AOC-30M-QN-BO InfiniBand fibre optic cable 30m QSFP28 Male/Male is a 30-metre active optical cable that provides high-bandwidth connectivity between QSFP28 ports. Built for data centre and high-performance computing environments, this cable supports low-latency, high-throughput links and is intended for direct connection of switches, servers and storage devices where reliable, long-reach optical links are required.

Advantages

This QSFP28 infiniBand cable offers a single-cable solution for 40G/100G-class links with minimal signal loss and reduced power consumption compared with equivalent copper assemblies. The active optical design maintains signal integrity over the full 30 m distance and reduces electromagnetic interference sensitivity. With male-to-male QSFP28 connectors, the cable allows simple plug-and-play installation and consistent performance in dense rack environments.

Suitable for

• Interconnecting QSFP28 ports in data centre switches and routers
• High-performance computing clusters requiring low-latency links
• Direct server-to-switch and storage-to-switch links in rack installations
• Short- to medium-reach optical paths within enterprise and colocation facilities

Key specifications

• Cable type: Active optical cable (AOC)
• Connector type: QSFP28 male to QSFP28 male
• Length: 30 metres
• Interface: InfiniBand-compatible high-speed optical link
• Performance: Designed for low latency and high throughput over specified length
• Environment: Suitable for data centre and rack-mounted equipment

How to use

Ensure both endpoints support QSFP28 form-factor ports and are powered off or compliant with hot-plug procedures before insertion. Align the QSFP28 connectors with the module cages and insert until latched; confirm link status via host equipment indicators or management interfaces. Route the cable to avoid sharp bends and excessive tension; maintain the minimum bend radius specified by the manufacturer. For removal, release the connector latch and withdraw the plug in a straight line to avoid stressing the fibre components.

Recommendations

For reliable operation, avoid repeated tight bends and mechanical stress, keep connector end-faces clean using appropriate fibre cleaning tools, and verify compatibility with the host ports and firmware versions. Use proper cable management in racks to maintain airflow and prevent signal degradation.
