BlueOptics AOC-Q-Q-40G-7M-BO InfiniBand fibre optic cable QSFP 7m Male/Male

The BlueOptics AOC-Q-Q-40G-7M-BO InfiniBand fibre optic cable QSFP 7m Male/Male is a 7-metre active optical cable designed for high-throughput interconnects in data centres and high-performance computing clusters. It uses QSFP-form-factor connectors at both ends in a male-to-male configuration to provide reliable 40Gbps-class links with low latency and electrical isolation inherent to fibre-optic transmission. This cable is suitable for short- to medium-reach connections where copper solutions are impractical or when immunity to electromagnetic interference and improved signal integrity are required.

Advantages

This QSFP active optical cable delivers high bandwidth and stable 40Gb-class performance while reducing heat and weight compared with equivalent copper assemblies. The optical medium provides electrical isolation and resistance to interference, supporting consistent throughput in dense rack environments. Its pre-terminated male-to-male QSFP connectors simplify installation and reduce the need for separate transceivers, offering a compact, low-power solution for server-to-switch, switch-to-switch, or storage interconnects.

Suitable for

• Short- to medium-reach links between QSFP ports in data centres
• High-performance computing clusters and GPU interconnects
• Switch-to-switch or server-to-switch 40Gbps connections
• Environments requiring immunity to electromagnetic interference

Key specifications

• Connector type: QSFP male to QSFP male
• Length: 7 metres
• Technology: Active Optical Cable (AOC)
• Supported data rate: up to 40 Gbps class link
• Signal medium: multimode optical fibre
• Latency: low-latency optical transmission suitable for HPC
• Power consumption: low compared with equivalent transceiver-based links

How to use

Identify QSFP ports on the devices you intend to connect and ensure both ports support 40Gb-class QSFP links. Handle the cable by the connector housings to avoid stress on the optical fibers and route it to avoid sharp bends or pinch points; respect the manufacturer’s minimum bend radius. Insert each QSFP male connector into the corresponding port until it seats securely and engage any retention mechanism present on the equipment. After connection, verify link status on the devices and check for expected data rates and error statistics.

Recommendations

For reliable operation, avoid repeated excessive flexing and keep the cable away from high-temperature areas. Use this active optical cable where reduced electromagnetic interference and improved signal integrity are required. Confirm QSFP compatibility and port support for AOC assemblies in device documentation before deployment.
