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

Active Optical Cable CBO QSFP-AOC-2M-UQ-BO is a 2 m InfiniBand connection cable with QSFP+ connectors on both ends. It provides a short-reach optical link designed for high-data-rate environments such as data centers and high performance computing clusters. The cable combines optical transmission with QSFP+ form-factor compatibility to deliver low latency and electrical isolation while maintaining the convenience of a plug-and-play direct attach solution for switches, servers and storage arrays.

Advantages

The InfiniBand AOC eliminates the need for separate transceivers and fiber patch cords by integrating optical transceivers into a factory-terminated cable assembly, reducing connector count and simplifying rack-level cabling. Its optical media reduces electromagnetic interference and provides electrical isolation between connected devices, while the QSFP+ interface supports high throughput and low latency for demanding interconnects. The 2 m length offers a compact reach suitable for top-of-rack and across-rack connections without excess slack.

Suitable for

• Short-reach interconnects between QSFP+ ports on switches and routers
• Server-to-switch connections in dense rack deployments
• Inter-node links within HPC clusters and storage arrays
• Low-latency links in latency-sensitive applications and fabrics

Key specifications

• Length: 2 meters
• Media: Active optical cable with integrated transceivers
• Application: InfiniBand short-reach high-speed links
• Performance: Designed for low latency and high throughput
• Electrical characteristics: Optical isolation between devices

How to use

Install the cable by inserting QSFP+ plugs into the matching QSFP+ ports on both devices until the latch engages. Ensure both endpoints support QSFP+ AOC modules and are powered off or in a hot-pluggable state according to equipment guidelines before insertion or removal. Route the cable to avoid sharp bends and mechanical strain: maintain bend radius recommended by the manufacturer and secure excess length to prevent movement within the rack. Verify link status on connected equipment and confirm negotiated speeds and lane configurations through device management interfaces.

Recommendations

Use the cable within recommended ambient temperature and humidity ranges and avoid exposure to liquids or contaminants. For best signal integrity, avoid tight bends and kinks; follow rack cable-management practices to prevent strain on the QSFP+ connectors. Confirm compatibility with switch and HBA firmware or vendor compatibility lists when deploying in production networks.
