Cable óptico activo InfiniBand CBO QSFP-AOC-20M-ZA-BO 20 m QSFP+ a QSFP+

CBO InfiniBand Active Optical Cable QSFP-AOC-20M-ZA-BO is a 20 m QSFP+ to QSFP+ active optical link designed for high-speed server, switch and storage interconnects. The cable integrates QSFP+ modules with electrical-to-optical conversion to deliver low-latency, high-bandwidth data transmission over 20 meters while reducing electromagnetic interference and simplifying cable routing in data centers and HPC clusters.

Advantages

The active optical design provides consistent signal integrity across the full 20 m length and eliminates the need for external transceivers. Integrated QSFP+ endpoints minimize connector-to-connector losses and support typical InfiniBand bandwidths and low-latency operation. The fiber-based link reduces susceptibility to electromagnetic interference and allows thinner, lighter cabling compared with copper equivalents, improving airflow and cable management in dense rack environments.

Suitable for

• High-performance computing clusters and inter-node links
• Top-of-rack and spine switch interconnects in data centers
• Server-to-storage connections requiring low latency and high throughput
• Environments needing reduced EMI and improved cable routing

Key specifications

• Connector type: QSFP+ to QSFP+
• Length: 20 meters
• Medium: active optical cable with integrated transceivers
• Supported interface: InfiniBand (QSFP+ form factor)
• Performance: designed for low-latency, high-bandwidth data transmission typical of QSFP+ links
• EMI characteristics: optical link reduces electromagnetic interference compared with copper cables
• Physical: lightweight, flexible fiber construction for improved cable management

How to use

Install the cable by inserting each QSFP+ module into the QSFP+ port of the connected devices until the latch engages. Ensure both ends are fully seated and that the devices are powered and configured to use the InfiniBand QSFP+ interface. No separate transceivers or additional configuration is normally required beyond standard port enablement and link negotiation on the connected equipment. Handle the cable by the connector bodies and avoid tight bends near the terminations to maintain optical performance.

Recommendations

For reliable operation, route the cable to avoid sharp bends and high-tension situations; maintain the minimum bend radius specified by the manufacturer and keep the cable clear of high-voltage sources. Verify compatibility with your switches, servers, and storage devices that support QSFP+ InfiniBand ports and confirm firmware or driver requirements if necessary. Regularly inspect connectors for contamination and clean with approved fiber-optic tools when required.
