CBO InfiniBand Active Optical Cable QSFP-AOC-20M-DL-BO 20 m, QSFP+ to QSFP+

CBO InfiniBand Active Optical Cable QSFP-AOC-20M-DL-BO 20 m, QSFP+ to QSFP+ is a 20-meter active optical link engineered for high-speed InfiniBand interconnects. The QSFP+ to QSFP+ AOC converts electrical signals to optical within the cable assembly to deliver low-latency, high-bandwidth connectivity across distances that exceed typical copper cabling. It is intended for use in environments where predictable performance, reduced electromagnetic interference and consolidated cabling are required, such as data centers and high performance computing clusters.

Advantages

The active optical construction provides consistent signal integrity over the full 20 m length while maintaining the form factor and compatibility of QSFP+ connectors. Compared with passive copper cables, this AOC reduces weight and bulk, resists EMI and supports longer reach without active transceivers at each end. The integrated design simplifies installation and reduces points of failure by combining optical transceivers and fiber into a single assembly.

Suitable for

• Server-to-switch and switch-to-switch InfiniBand links in data centers
• Interconnects in high performance computing (HPC) clusters
• Storage area network (SAN) fabrics requiring low latency and high throughput
• Racks and zones where longer reach and reduced electromagnetic interference are needed

Key specifications

• Cable type: Active Optical Cable (AOC)
• Connector type: QSFP+ to QSFP+
• Length: 20 meters
• Protocol compatibility: InfiniBand (QSFP+ form factor)
• Performance characteristics: low latency, high bandwidth suitable for InfiniBand data rates
• Physical attributes: lightweight fiber assembly with integrated transceiver modules

How to use

Insert each QSFP+ connector into compatible QSFP+ ports on host adapters, switches or transceivers, ensuring proper alignment and a secure latch. The cable is hot-pluggable; verify port compatibility and link speed settings on connected equipment if needed. Avoid tight bends and secure cable routing to maintain the specified minimum bend radius and prevent physical strain on connectors. Use standard diagnostic tools provided by the host or switch to confirm link status and performance after installation.

Recommendations

For reliable long-term operation, route the AOC in cable management trays or along rack cable guides to prevent kinks and excessive bending. Confirm that connected devices support QSFP+ AOC links and configured InfiniBand speeds; keep firmware and drivers up to date to ensure full compatibility and optimal performance.
