InfiniBand Active Optical Cable CBO QSFP-AOC-20M-LS-BO 20 m QSFP to QSFP

InfiniBand Active Optical Cable CBO QSFP-AOC-20M-LS-BO is a 20 m QSFP-to-QSFP active optical link from BlueOptics designed for high-speed InfiniBand connections. The factory-assembled AOC combines optical transceivers and fiber in a single cable assembly to provide a low-latency, high-bandwidth link between compatible QSFP ports in servers, switches and storage systems. Its optical design reduces electromagnetic interference and removes the need for separate transceiver modules, simplifying rack-to-rack or intra-rack cabling in data center and high-performance computing environments.

Advantages

This active optical cable delivers consistent signal integrity over a 20 metre span while maintaining the plug-and-play convenience of QSFP form-factor connectors. The integrated optical link offers lower weight and improved thermal characteristics compared with equivalent copper assemblies, and reduces cable management complexity by combining connector and transceiver functions into one unit. The cable is factory-terminated and tested to ensure compatibility and reliable performance in compatible InfiniBand environments.

Suitable for

• High-performance computing clusters requiring low-latency server interconnects
• Data centre switch-to-switch or switch-to-server links over medium distance
• Storage arrays and SAN fabrics using QSFP InfiniBand interfaces
• Environments where reduced electromagnetic interference is important

Key specifications

• Connector type: QSFP to QSFP optical assembly
• Cable type: Active optical cable (AOC) with integrated transceivers
• Length: 20 metres
• Application: InfiniBand high-speed data interconnects
• Latency: Low-latency optical transmission suitable for HPC workloads
• EMI performance: Immunity to electromagnetic interference compared with copper

How to use

Install the AOC by inserting each QSFP connector into the corresponding QSFP port on the devices to be linked, ensuring proper alignment and secure seating. No separate transceivers or fibre termination are required. After connection, verify link status on the host devices and configure the InfiniBand interfaces according to your network settings. For optimal performance, avoid tight bends and excessive torsion; route the cable through cable management paths that maintain a gentle bend radius.

Usage recommendations

Store and handle the cable in a clean environment and avoid kinking or crushing. Maintain the manufacturer’s minimum bend radius and protect connector ferrules from contamination when connectors are not in use. Use this AOC in compatible QSFP-equipped systems and confirm firmware or vendor compatibility if using matched equipment from different manufacturers.
