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

The CBO InfiniBand Active Optical Cable QSFP-AOC-20M-CI-BO 20 m is a 20‑meter active optical link designed for InfiniBand-compatible QSFP ports. It delivers optical transmission for high-bandwidth, low-latency interconnects between servers, switches and storage systems. The cable is intended for data center, rack-to-rack and HPC cluster environments where electrical cabling is impractical or where reduced electromagnetic interference and simplified routing are required.

Advantages

This active optical cable provides a longer reach than typical direct-attach copper while maintaining low latency and high throughput. Its QSFP form-factor plug ensures compatibility with standard QSFP ports and simplifies hot-plug installation. Optical transmission reduces susceptibility to electromagnetic interference and heat generation compared with copper alternatives, and the cable’s flexible construction supports tidy cable management in dense rack environments.

Suitable for

• High-performance computing clusters requiring low-latency node interconnects
• Data center server-to-switch or switch-to-switch links within racks and between adjacent racks
• Storage area network interconnections where optical links are preferred
• Environments with high electromagnetic interference where optical isolation is beneficial

Key specifications

• Cable type: Active Optical Cable (AOC) for QSFP ports
• Length: 20 meters
• Interface: QSFP connector form-factor compatible with InfiniBand QSFP ports
• Transmission medium: optical fiber with integrated transceivers
• Performance: designed for high-bandwidth, low-latency data interconnects
• Application environment: data center, rack-to-rack, HPC clusters, storage networks

How to use

Insert each QSFP connector into the corresponding QSFP port on devices that support InfiniBand-compatible QSFP AOCs. Ensure ports are powered and configured according to the host device documentation; the cable contains active optical components and does not require separate power or external transceivers. Route the cable to avoid sharp bends and excessive strain, and secure it to cable management fixtures to maintain airflow and accessibility in racks. If link negotiation or firmware settings are required, follow the switch or host adapter vendor instructions for QSFP AOC links.

Recommendations

Use this AOC for short- to medium-range optical links up to 20 m where lower latency and reduced EMI are priorities. Avoid tight bends and kinks; maintain the manufacturer’s minimum bend radius. For optimal reliability, verify compatibility with your QSFP ports and keep device firmware up to date to ensure proper link negotiation.
