CBO AOC Cable Compatible with Dell CBL-QSFP-40GE-10M 10 m QSFP+ to QSFP+ Active Optical Cable

The CBO AOC Cable compatible with Dell CBL-QSFP-40GE-10M is a 10 meter QSFP+ to QSFP+ active optical cable designed for 40 Gigabit Ethernet links. It provides a lightweight, low-latency fiber connection for interconnecting servers, switches and other QSFP+-equipped devices in data center and enterprise network environments. The cable combines optical transmission with plug-and-play compatibility to support high-throughput, medium-distance connections where electromagnetic immunity and reduced weight are required.

Advantages

This active optical cable offers reduced electromagnetic interference compared with copper alternatives and delivers consistent 40 Gb/s throughput suitable for high-bandwidth applications. Its optical construction makes it lighter and more flexible than equivalent copper assemblies, simplifying cable management in dense racks and conduits. The QSFP+ connectors provide standardized connectivity for compatible networking equipment, and the 10 m length covers common cross-rack and intra-room distances without the need for transceivers.

Suitable for

• 40 Gigabit Ethernet server-to-switch and switch-to-switch links
• Data center uplinks, aggregation and spine-leaf architectures
• High-performance computing clusters and storage network connections
• Environments requiring low latency and immunity to electromagnetic interference

Key specifications

• Connector type: QSFP+ to QSFP+
• Length: 10 meters
• Nominal data rate: 40 Gb/s
• Cable type: Active Optical Cable (AOC)
• Transmission medium: multimode/mode-agnostic optical fiber suitable for short to medium distances
• Form factor: hot-pluggable QSFP+ modules on both ends

How to use

Install the cable by inserting each QSFP+ connector into the corresponding QSFP+ port on your equipment until the latch engages. Ensure both devices are powered and compatible with 40 GbE QSFP+ AOC links. No additional transceivers are required; the cable handles optical conversion internally. For best results, route the cable to avoid sharp bends, excessive tension and sources of mechanical damage. Verify link status via device LEDs or management interfaces after connection.

Usage recommendations

Use the cable for medium-distance connections within racks or between adjacent racks, and avoid running it near active copper power lines to minimize mechanical stress. Verify compatibility with your networking hardware vendor's supported AOC list and follow standard ESD precautions when handling QSFP+ connectors.
