BlueOptics Q28-AOC-30M-NK-BO cabo de fibra ótica InfiniBand 30m QSFP28 macho

The BlueOptics Q28-AOC-30M-NK-BO InfiniBand fibre optic cable 30m QSFP28 Male is a 30-metre active optical cable designed for high-speed interconnects in data centres and high-performance computing clusters. It uses QSFP28 form-factor connectors at both ends to support InfiniBand links and short- to mid-reach optical connections. The cable provides a lightweight, flexible alternative to copper and traditional transceiver-plus-patch-cord setups, enabling simplified rack-to-rack and switch-to-switch cabling while maintaining low latency and high bandwidth performance.

Advantages

This fibre optic cable offers high-density connectivity with compact QSFP28 ends that reduce rack clutter and improve airflow. The active optical design reduces power and weight compared with equivalent copper links, while delivering stable signal integrity over the 30 metre length. Compatibility with InfiniBand protocols and low-latency characteristics make it suitable for environments where predictable, high-throughput links are required. The single-cable solution simplifies deployment and reduces the number of intermediate modules needed.

Suitable for

• Rack-to-rack connections in data centres
• High-performance computing (HPC) cluster interconnects
• Switch-to-switch and server-to-switch links requiring InfiniBand
• Environments prioritising low latency and high bandwidth

Key specifications

• Cable type: active optical cable (AOC)
• Connector type: QSFP28 on both ends (male)
• Length: 30 metres
• Protocol support: InfiniBand
• Typical use: short- to mid-reach data centre interconnects
• Physical: lightweight and flexible fibre construction

How to use

Install the BlueOptics QSFP28 AOC by inserting each QSFP28 plug into the corresponding QSFP28 ports on the devices to be connected, ensuring the connector is aligned with the port key before seating. No external transceivers are required; the active optical components are integrated into the cable assemblies. Verify link status on connected devices after physical installation and perform any required link configuration or firmware checks on the networking equipment. Handle the cable by the connectors and avoid tight bends near the cable ends to maintain optical performance.

Recommendations

For reliable performance, route the cable with gentle bend radii and avoid compressing or kinking the optical fibre. Use appropriate management hardware in racks to secure the run and maintain airflow. Confirm that the connected switches and hosts support QSFP28 InfiniBand ports and appropriate link settings before deployment.
