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

The BlueOptics Q28-AOC-30M-RW-BO InfiniBand fibre optic cable 30m QSFP28 Male is a 30-metre active optical cable engineered for high-speed data transfer in data centre and high-performance computing environments. It uses QSFP28 form-factor connectors on both ends and supports the high bandwidth and low latency requirements of InfiniBand interconnects. The cable is intended for short- to medium-reach connections inside racks and between adjacent racks where reliable, low-latency links are required.

Advantages

This 30m active optical cable provides electrical isolation and reduced electromagnetic interference compared with copper alternatives, enabling stable signal integrity at high data rates. The QSFP28 connectors supply a compact, standardized interface for InfiniBand equipment and switches, while the optical medium lowers power dissipation and heat compared with copper direct-attach options. The single-cable assembly simplifies installation and cable management in dense rack environments.

Suitable for

• Interconnects between servers and InfiniBand switches within data centres
• High-performance computing clusters requiring low latency and high throughput
• Rack-to-rack connections where 30 m reach is sufficient
• Environments where reduced electromagnetic interference and improved signal integrity are needed

Key specifications

• Length: 30 metres
• Connector type: QSFP28 on both ends (male)
• Interface: InfiniBand-compatible high-speed optical link
• Cable type: Active optical cable (AOC)
• Suitable for short- to medium-reach data centre interconnects

How to use

Install the cable by inserting the QSFP28 connectors into the corresponding QSFP28 ports on switches, host channel adapters or servers, ensuring the retention latches engage. Route the cable to avoid sharp bends and mechanical stress; maintain the manufacturer’s recommended minimum bend radius for optical assemblies. No separate transceivers or additional optical modules are required, as the active optical cable integrates both ends. Verify link status on connected devices and check for expected link speeds and error rates after installation.

Recommendations

Store and handle the cable in a clean, dry environment. Avoid kinking or crushing the assembly and respect bend radius limits. For optimal performance, use within rack or row-level deployments where a 30 m active optical cable provides the required reach and when InfiniBand-compatible QSFP28 ports are available on both ends.
