CBO Cable CBL-420-BO QSFP Male–Male 20 m, 40 Gbit/s

CBO Cable CBL-420-BO QSFP Male–Male 20 m, 40 Gbit/s is a direct-attach QSFP copper cable designed to provide a point-to-point connection between compatible QSFP ports. With a fixed length of 20 meters and support for 40 Gbit/s aggregated data throughput, this cable is intended for short- to medium-reach interconnects in network racks and equipment where QSFP interfaces are present. The cable provides a simple physical link that delivers low latency and high throughput for data center and enterprise networking environments.

Advantages

The cable offers a reliable, factory-terminated QSFP-to-QSFP connection that eliminates the need for separate transceivers, reducing component count and simplifying installation. Its 40 Gbit/s capability supports high-bandwidth traffic such as server aggregation and switch uplinks while maintaining low signal loss over the specified 20 m length. The ready-made assembly minimizes setup time and potential compatibility issues when used with standard QSFP ports.

Suitable for

• Data center top-of-rack and leaf-spine interconnects
• Server-to-switch and switch-to-switch high-speed links
• Network equipment uplinks and appliance connectivity
• Short- to medium-distance QSFP port connections within racks and between adjacent racks

Key specifications

• Connector type: QSFP male to QSFP male
• Length: 20 m
• Maximum data rate: 40 Gbit/s
• Cable type: direct-attach copper assembly
• Typical use: short- to medium-reach high-speed interconnect

How to use

Install the cable by inserting each QSFP male connector into compatible QSFP ports on the two devices to be linked. Ensure both devices are powered down or that hot-plugging is supported by the equipment if the connection is made while devices are live. Align the connector latch and press until it seats securely; confirm link status through device indicators or management interfaces. Route the cable to avoid sharp bends and mechanical strain, maintaining the recommended bend radius for copper assemblies.

Usage recommendations

Use this cable for direct QSFP-to-QSFP links in environments where a 20 m fixed-length copper assembly provides sufficient reach. Avoid exposure to excessive mechanical stress, high temperatures, or liquids. Verify port compatibility and supported link speeds on both devices before deployment to ensure proper operation at 40 Gbit/s.
