InfiniBand Active Optical Cable CBO QSFP-AOC-10M-IA-BO 10 m QSFP+ to QSFP+

The InfiniBand Active Optical Cable CBO QSFP-AOC-10M-IA-BO is a 10-metre QSFP+ to QSFP+ active optical link designed for high-speed data center and high performance computing (HPC) environments. This AOC replaces equivalent copper links at medium distances to deliver lower attenuation, electrical isolation between connected devices, and consistent signal integrity for InfiniBand and other QSFP+-compatible interconnects. The cable is aimed at connecting servers, switches and storage systems where QSFP+ ports are used for 40 Gbps-class links over short to medium reaches.

Advantages

The active optical construction offers reduced signal loss and immunity to electromagnetic interference compared with copper cables, helping to maintain low latency and stable throughput. A 10 m length provides flexible rack-to-rack or within-rack routing without the bulk and weight of long copper assemblies. The QSFP+ form-factor connectors ensure compatibility with QSFP+ ports and hot-pluggable operation, while the optical medium provides electrical isolation that can protect equipment from ground loops.

Suitable for

• 40 Gbps InfiniBand or Ethernet interconnects between switches and servers
• High performance computing clusters requiring low-latency links
• Server-to-storage and switch-to-switch connections in data centers
• Environments where electrical isolation and reduced EMI are required

Key specifications

• Connector type: QSFP+ to QSFP+
• Length: 10 metres
• Link medium: active optical cable (AOC)
• Data rate class: QSFP+ (40 Gbps-class links, backwards-compatible with QSFP+ ports)
• Latency: low-latency optical transmission suitable for HPC and data center use
• Electrical isolation provided by optical link

How to use

Install the cable by aligning each QSFP+ connector with the corresponding QSFP+ port on your devices and inserting until the connector latch engages. Ensure ports are powered and that device firmware or drivers support QSFP+ AOC connections. Route the cable to avoid sharp bends and mechanical stress; maintain the minimum bend radius recommended for active optical assemblies. For replacement or reconfiguration, hot-plugging is supported when connected equipment allows it, but follow your hardware vendor’s procedures to avoid link disruption.

Usage recommendations

Verify compatibility with your switch, server or storage vendor for QSFP+ active optical cables and confirm supported data rates and firmware requirements. Keep the cable free from tight bends and physical strain, and avoid exposure to liquids or excessive heat to preserve performance and service life.
