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

InfiniBand Active Optical Cable CBO QSFP-AOC-20M-MA-BO 20 m QSFP+ to QSFP+ is a factory-terminated active optical link for high-speed data center interconnects. The 20-meter QSFP+ to QSFP+ AOC integrates optical transceivers into the cable assembly, eliminating the need for separate pluggable modules. It is engineered to provide low latency, high bandwidth, and immunity to electromagnetic interference for reliable rack-to-rack or switch-to-switch connections where a 20 m reach is required.

Advantages

The cable delivers high data rates and consistent signal integrity while reducing the number of field-installable transceivers. Its active optical design minimizes insertion loss over the 20 m span and reduces heat and power consumption compared with equivalent copper solutions. The factory-terminated assembly simplifies deployment and maintenance, and the QSFP+ connectors ensure compatibility with equipment supporting InfiniBand and QSFP+ interfaces.

Suitable for

• Rack-to-rack connectivity in data centers requiring a 20 m optical reach
• Switch-to-switch links in high-performance computing and storage networks
• Low-latency interconnects for InfiniBand and QSFP+ enabled equipment
• Environments sensitive to electromagnetic interference where optical cabling is preferred

Key specifications

• Connector type: QSFP+ to QSFP+
• Length: 20 meters
• Cable type: Active Optical Cable (AOC)
• Interface standard: InfiniBand / QSFP+
• Transmission medium: multimode optical link with integrated optical transceivers
• Performance: designed for high data rates and low latency suitable for QSFP+ lane aggregation
• Electromagnetic immunity: optical transmission eliminates EMI concerns associated with copper cabling

How to use

Install the AOC by inserting each QSFP+ connector into the corresponding QSFP+ port on the devices to be linked until the connector latches. Ensure both ends are fully seated and that the devices are powered and configured for the intended InfiniBand or QSFP+ link speed. No separate transceivers are required; the cable assemblies are factory-terminated and ready for immediate use. Handle the cable by the connector housing when mating or un-mating and avoid tight bends below the manufacturer-recommended bend radius to preserve optical performance.

Usage recommendations

Verify device compatibility with QSFP+ active optical cables and confirm link settings in the switch or host firmware before deployment. Maintain minimum bend radius and avoid sharp kinks; route the cable to prevent mechanical strain on connectors. For permanent installations, check environmental conditions such as temperature and airflow to ensure stable operation.
