CBO InfiniBand Active Optical Cable QSFP-AOC-20M-VA-BO, QSFP to QSFP, 20 m

CBO QSFP-AOC-20M-VA-BO is a 20 m InfiniBand active optical cable with QSFP connectors on both ends, built for high-speed interconnects in data centers and high-performance computing environments. The cable integrates optical transceivers and electrical interface into a single assembly, providing fiber-based connectivity without the need for separate SFP/QSFP transceivers. It supports long-reach optical links up to 20 meters while maintaining low latency and signal integrity required for server-to-switch, switch-to-switch and storage interconnects.

Advantages

The active optical construction reduces electromagnetic interference and heat generation compared with copper alternatives while enabling longer reach at high data rates. Integrated QSFP connectors simplify installation and reduce component count by eliminating external transceivers. The cable's design prioritizes signal integrity and low latency, suitable for dense rack environments and equipment with QSFP ports. Its 20 m length offers flexibility for larger racks, aisle-to-aisle connections, and cross-row links.

Suitable for

• Server to switch connections in data centers
• Switch to switch links in aggregation and spine-leaf topologies
• Storage network interconnects and SAN environments
• High-performance computing clusters (InfiniBand)
• Aisle-to-aisle or cross-rack optical links up to 20 m

Key specifications

• Connector type: QSFP to QSFP optical assembly
• Length: 20 meters (active optical cable)
• Interface: InfiniBand-compatible QSFP electrical/optical interface
• Transmission medium: Active optical fiber with integrated transceiver electronics
• Performance focus: Low latency, high signal integrity for high-speed interconnects
• Typical use environment: Data center racks, HPC clusters, storage networks

How to use

Install the cable by plugging each QSFP connector into compatible QSFP ports on the devices to be connected; ensure ports are powered and configured for InfiniBand or the supported QSFP protocol. Route the cable to avoid tight bends and mechanical strain; maintain the minimum bend radius specified by the manufacturer to preserve optical performance. Verify link status and speeds in the host and switch management interfaces after insertion. If necessary, consult equipment documentation for port compatibility and firmware requirements.

Recommendations

Use in environments where optical reach and low latency are required. Avoid excessive bending, crushing, or exposure to temperatures outside the equipment manufacturer's specified operating range. For mixed-vendor environments, confirm QSFP compatibility and supported InfiniBand link speeds before deployment.
