BlueOptics 40GB-F07-QSFP-BO InfiniBand fibre optic cable 7 m QSFP Male/Male

The BlueOptics 40GB-F07-QSFP-BO InfiniBand fibre optic cable is a 7 m duplex cable with QSFP male-to-male connectors designed for high-speed data transmission in data centres and enterprise networks. Built for short- to medium-reach links, this cable supports low signal loss and consistent throughput for InfiniBand applications, switch-to-switch connections, server and storage interconnects, and other high-density networking scenarios.

Advantages

This 7 m fibre cable provides a reliable electrical isolation and immunity to electromagnetic interference, resulting in improved signal integrity compared with copper alternatives. The QSFP male connectors ensure compact, high-density port utilization and straightforward installation in QSFP-compatible ports. The fibre construction minimises attenuation over the cable length, helping to maintain stable 40 Gbit/s performance under standard operating conditions.

Suitable for

• InfiniBand switch-to-switch links in data centres
• Server and storage interconnects requiring 40 Gbit/s bandwidth
• High-density rack installations with QSFP ports
• Short- to medium-reach fibre optic connections in enterprise networks

Key specifications

• Cable type: duplex fibre optic cable
• Length: 7 m
• Connector type: QSFP male to QSFP male
• Supported data rate: 40 Gbit/s (InfiniBand-compatible)
• Application: data centre and high-density networking
• Signal medium: optical fibre for low attenuation and EMI immunity

How to use

Install the cable by aligning each QSFP male connector with the corresponding QSFP port on the devices to be connected. Insert the connectors fully until they click or sit firmly in the port, ensuring correct orientation and avoiding excessive force. Route the cable to avoid tight bends and mechanical stress; maintain the manufacturer’s recommended bend radius where possible. Verify link status on connected devices and perform any required link configuration for InfiniBand fabrics or 40 Gbit/s Ethernet settings.

Recommendations

For reliable long-term performance, avoid sharp bends and mechanical strain, keep connectors clean and capped when not in use, and use appropriate cable management in dense rack environments. Match the cable with QSFP-compatible hardware and check device compatibility for InfiniBand or 40 Gbit/s operation before deployment.
