InfiniBand Active Optical Cable CBO QSFP-AOC-20M-LC-BO 20 m QSFP+ to QSFP+

The InfiniBand Active Optical Cable CBO QSFP-AOC-20M-LC-BO 20 m QSFP+ to QSFP+ is a factory-terminated, fixed-length optical interconnect designed for high-performance InfiniBand environments. With QSFP+ connectors at both ends and a 20 meter optical link, this active optical cable delivers low-latency, high-bandwidth connectivity for servers, switches and storage arrays while minimizing electromagnetic interference and simplifying cabling runs in dense rack deployments.

Advantages

This 20 m active optical cable provides consistent optical signal quality without the need for separate transceivers, reducing component count and simplifying installation. Its QSFP+ ends enable native compatibility with InfiniBand QSFP+ ports and high-speed switch interfaces. The fixed-length AOC reduces crosstalk and EMI compared with copper alternatives and supports predictable performance for short-range uplinks and inter-rack links in data centers and HPC clusters.

Suitable for

• Short-distance interconnects between top-of-rack switches and adjacent racks
• High-performance computing (HPC) cluster links that require low latency
• Server-to-switch and switch-to-switch connections in data centers
• Storage array interconnects where optical isolation is preferred

Key specifications

• Connector type: QSFP+ to QSFP+
• Length: 20 meters fixed optical cable
• Cable type: Active Optical Cable (AOC)
• Intended interface: InfiniBand high-speed links
• Signal transmission: Optical, reducing electromagnetic interference
• Typical use: Short-range data center and HPC interconnects

How to use

Install the cable by inserting each QSFP+ connector into the appropriate QSFP+ ports on your devices, ensuring the connector latch engages. No separate transceivers are required; the active electronics are integrated in the cable ends. Verify link lights and host interfaces after connection and follow your system vendor’s recommended procedures for link configuration and speed negotiation. Avoid bending the cable beyond the manufacturer’s minimum bend radius and route it to prevent sharp kinks or stress on the connectors.

Recommendations

For reliable operation, use this AOC for links within the specified 20 m length and in environments where optical isolation from electrical noise is beneficial. Maintain proper rack management to avoid excessive strain on the cable and confirm firmware and driver support for QSFP+ active optical links on connected devices.
