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

The Active Optical InfiniBand Cable CBO QSFP-AOC-2M-LE-BO, QSFP to QSFP, 2 m is a 2-metre certified active optical cable engineered for high-speed InfiniBand interconnects. It integrates QSFP connectors at both ends and removes the need for separate transceiver modules, offering a compact, short-reach optical link for server-to-server, switch-to-switch and storage connections. The cable is intended for data centre and high-performance computing (HPC) environments where low latency, high bandwidth and reliable QSFP-to-QSFP connectivity are required.

Advantages

This active optical cable provides high data throughput with reduced electromagnetic interference compared with copper alternatives. Its integrated QSFP connectors simplify installation by eliminating separate optical transceivers, reducing component count and rack space usage. The 2-metre length supports flexible rack and chassis layouts while maintaining short-reach signal integrity and low latency suitable for InfiniBand fabrics. The cable is designed for consistent performance in dense networking environments and for minimizing cable bulk in tight cable management scenarios.

Suitable for

• High-performance computing clusters and InfiniBand fabrics
• Interconnects between rack servers, top-of-rack switches and storage arrays
• Short-reach fibre links within data centres and equipment cabinets
• Environments requiring QSFP-to-QSFP optical connectivity without separate transceivers

Key specifications

• Connector type: QSFP to QSFP optical connectors
• Cable type: Active optical cable (AOC)
• Length: 2 metres
• Target application: InfiniBand short-reach interconnects
• Latency characteristics: low-latency optical link suitable for HPC
• Form factor: QSFP-compatible compact assembly for dense deployments

How to use

Install the cable by inserting each QSFP connector into the corresponding QSFP port on the devices to be linked. Ensure ports are powered down or follow hot-plug guidance from the device manufacturer if supported. Verify that the cable is seated correctly and that link indicators on the devices show an active connection. For InfiniBand fabrics, confirm link parameters and lane configurations in the host or switch management interface. Route the cable to avoid sharp bends and maintain the manufacturer’s minimum bend radius to preserve optical performance.

Recommendations

Use this 2 m active optical QSFP-to-QSFP cable for short-reach connections in dense rack layouts and HPC clusters. Avoid tight bends and mechanical strain, keep connectors covered when not in use, and follow equipment vendor guidance on hot-plugging and link negotiation to ensure stable, low-latency operation.
