InfiniBand Active Optical Cable CBO QSFP-AOC-2M-NK-BO 2 m QSFP+ to QSFP+

CBO QSFP-AOC-2M-NK-BO is a 2 m InfiniBand active optical cable (AOC) with QSFP+ to QSFP+ connectors, engineered for short-reach, high-speed interconnects in data center and high-performance computing environments. The cable integrates optical transceivers and electrical-to-optical conversion within the assembly to deliver high bandwidth and low latency links between switches, servers and storage systems while reducing susceptibility to electromagnetic interference compared with copper cabling.

Advantages

The active optical design offers stable signal integrity over a 2 meter span, enabling multi-lane high-speed transmission with lower insertion loss and reduced crosstalk. Integrated transceivers eliminate the need for separate modules, simplifying installation and inventory management. The QSFP+ to QSFP+ form factor supports industry-standard InfiniBand and Ethernet implementations, and the optical medium reduces weight and bulk in dense rack deployments.

Suitable for

• Short-reach switch-to-switch connections within racks or adjacent racks
• Server-to-switch uplinks in high-performance computing clusters
• Storage array interconnects requiring high bandwidth and low latency
• Data center top-of-rack and spine-leaf architectures with QSFP+ ports

Key specifications

• Cable type: Active Optical Cable (AOC) with integrated transceivers
• Connector type: QSFP+ to QSFP+
• Length: 2 meters
• Supported link: InfiniBand high-speed interconnects (multi-lane)
• Latency characteristics: low-latency optical transmission suitable for HPC workloads
• EMI performance: immune to electromagnetic interference compared with copper alternatives

How to use

Install the CBO QSFP-AOC-2M-NK-BO by inserting each QSFP+ connector into the compatible QSFP+ ports on network switches, servers or storage devices. Ensure that devices are powered down or that hot-swap procedures for QSFP+ modules are followed according to the host equipment documentation. Verify link status through device LEDs or management interfaces and monitor link negotiation to confirm supported speeds and lane configurations.

Recommendations

Use this 2 m QSFP+ active optical cable for direct connections within racks or between adjacent racks where low latency and high bandwidth are required. Avoid tight bends and maintain minimum bend radius specified by the manufacturer. Store and handle the cable by the connector housings to reduce stress on the fiber and transceiver assemblies.
