Cabo de fibra ótica InfiniBand BlueOptics AOC-QSFP-40G-7M-BO 7m QSFP macho

The BlueOptics AOC-QSFP-40G-7M-BO InfiniBand fibre optic cable 7m QSFP Male is a 7-metre active optical cable designed for high-speed short-reach interconnects in server rooms and data centres. It features QSFP form-factor connectors on both ends and supports 40 Gigabit data rates suitable for aggregation, switch-to-switch and switch-to-server links. The cable construction minimises electromagnetic interference and provides consistent signal integrity for latency-sensitive environments.

Advantages

This 7 m InfiniBand fibre optic cable delivers stable 40G connectivity with low power consumption typical of active optical cables. Its QSFP male connectors ensure compatibility with a wide range of QSFP ports used in modern networking equipment. The optical link offers superior noise immunity compared with copper alternatives and maintains performance over the specified length without the need for transceivers or additional modules.

Suitable for

• High-performance computing clusters and InfiniBand fabric links
• Data centre switch-to-switch and switch-to-server connections
• Rack-to-rack or chassis interconnects within short-reach deployments
• Environments requiring low-latency, high-bandwidth links

Key specifications

• Cable type: Active optical cable (AOC)
• Connector type: QSFP male to QSFP male
• Data rate: 40 Gbit/s
• Length: 7 metres
• Transmission medium: Fibre optic
• Typical use: Short-reach high-speed interconnects

How to use

Install the cable by inserting each QSFP male connector into the corresponding QSFP port on networking devices, ensuring connectors are aligned and fully seated. Verify device link status through network management interfaces or LED indicators. No separate transceivers are required; the active optical cable integrates the necessary optical/electrical components. When unplugging, gently press any retention latch and pull the connector straight out to avoid damaging the port.

Recommendations

Route the cable to avoid sharp bends and mechanical stress; maintain the manufacturer’s minimum bend radius. Use labelled cable management to track connections in dense installations. Ensure firmware and driver compatibility on connected devices for optimal 40G operation, and inspect connectors for dust or debris before insertion to preserve signal quality.
