AOC Active Optical Cable CBO CBL-QSFP-40GE-2M 2 m 40 Gbps QSFP+ to QSFP+

The AOC Active Optical Cable CBO CBL-QSFP-40GE-2M is a 2-meter, 40 Gbps QSFP+ to QSFP+ direct connect cable designed for short-reach high-speed interconnects. This active optical cable provides a compact, low-latency link between QSFP+ ports on servers, switches and storage systems. Its optical design reduces electromagnetic interference and improves signal integrity compared with equivalent copper assemblies, making it suitable for dense rack environments and modern data center topologies.

Advantages

This 2 m AOC delivers full 40 Gbps line-rate performance with lower power consumption than many active copper options and improved thermal behaviour in confined spaces. The QSFP+ to QSFP+ active optical design reduces crosstalk and EMI, supports consistent signal quality over the specified distance, and simplifies cabling by combining transceiver and fiber functions into a single assembly. Compact QSFP+ connectors allow for high port density on switches and servers.

Suitable for

• 40 Gbps server-to-switch uplinks in enterprise networks
• Switch-to-switch interconnects within a rack or adjacent racks
• High-performance storage arrays requiring short-reach 40 Gbps links
• Data center top-of-rack and leaf-spine architectures

Key specifications

• Connector type: QSFP+ to QSFP+
• Link length: 2 metres (fixed cable)
• Maximum data rate: 40 Gbps aggregate
• Cable type: Active optical cable (AOC)
• Low latency design suitable for short-reach interconnects
• Reduced electromagnetic interference compared with copper

How to use

Install the cable by aligning and inserting the QSFP+ connectors into compatible QSFP+ ports on networking devices until the connector latches engage. No separate transceivers or fiber patching are required since the assembly integrates the optical transceiver functions. Ensure both devices support 40 Gbps QSFP+ links and verify link status via device management interfaces. Route the 2 m cable to avoid tight bends and mechanical stress on the connectors.

Recommendations

For reliable operation, use this AOC in short-reach applications up to the specified 2 m length, keep connectors clean and protected from dust, and avoid sharp bends or excessive pulling force. Confirm device compatibility with QSFP+ active optical cables and check firmware or hardware documentation for any required port settings when integrating into existing networks.
