Active Optical InfiniBand Cable CBO QSFP-AOC-2M-VA-BO, QSFP to QSFP, 2 m

Active Optical InfiniBand Cable CBO QSFP-AOC-2M-VA-BO, QSFP to QSFP, 2 m is a 2-metre active optical cable designed for short-reach high-speed InfiniBand links. The cable integrates electrical-to-optical conversion in its transceiver modules to deliver high bandwidth and low latency for server-to-switch and switch-to-switch connections. Its QSFP-to-QSFP connectors provide a compact, hot-pluggable interface compatible with QSFP ports used in data centre and HPC environments.

Advantages

The active optical design reduces electromagnetic interference and signal degradation over copper at similar lengths while maintaining low power consumption and predictable latency. At 2 metres, the cable offers a neat, flexible connection that simplifies rack cabling and improves airflow compared with bulkier passive copper alternatives. Built-in optical conversion removes the need for separate transceivers and fibre patching for short interconnects.

Suitable for

• Server-to-switch and switch-to-switch connections in data centres
• High-performance computing clusters and InfiniBand fabrics
• Short-reach interconnects where low latency and high bandwidth are required
• Rack environments needing compact QSFP connections and tidy cable management

Key specifications

• Cable type: Active Optical Cable (AOC)
• Connector type: QSFP to QSFP
• Length: 2 metres
• Application: InfiniBand high-speed link
• Transmission medium: Optical with integrated electrical-to-optical conversion
• Form factor: Hot-pluggable QSFP modules integrated in cable ends

How to use

Insert each QSFP connector into matching QSFP ports on the devices to be linked, ensuring correct alignment and fully seating the module until the retention mechanism engages. No separate optics or fibre patch cords are required. After connection, verify link status through the host or switch management interface and monitor for expected port LEDs or system messages. For removal, release the retention mechanism and gently extract the connector while supporting the cable to avoid strain on the port.

Recommendations

Use the cable for short interconnects inside racks or between adjacent racks. Avoid tight bends near the connector ends and maintain minimum bend radii specified by the manufacturer. Keep connectors clean and store the cable in a protective loop when not in use. For optimal performance, verify compatibility with QSFP ports and firmware requirements on networking equipment before deployment.
