Dell 7m QSFP+ to 4xSFP+ 40Gbps Breakout Cable

Overview

The Dell 462-3641 is a breakout cable designed to convert a single QSFP+ port into four independent SFP+ connections, delivering a combined bandwidth of up to 40Gbps. With a 7-meter length and copper direct attach design, it is ideal for short-distance connections within or between racks without the need for separate transceivers. This cable simplifies high-speed networking setups by providing reliable and cost-effective links for data centers and server environments.

Key features

• Direct attach copper cable that eliminates the need for additional transceivers, reducing overall cost and complexity
• Breaks out one 40Gbps QSFP+ port into four 10Gbps SFP+ links, enabling flexible network segmentation and device connectivity
• 7-meter length supports short rack-to-rack or intra-rack connections, making it suitable for dense data center environments
• Tested and validated with Dell servers, switches, and storage systems to ensure seamless integration and reliable performance
• Plug-and-play operation minimizes deployment time and simplifies network upgrades or expansions
• Supported by Dell technical assistance for troubleshooting and configuration guidance

Key specs

• Cable length: 7 meters
• Connector type: QSFP+ to 4x SFP+
• Data rate: Aggregated 40Gbps (4x 10Gbps links)
• Cable type: Direct attach copper
• Compatibility: Designed for Dell networking and server equipment

Connectivity and compatibility

This breakout cable is optimized for use with Dell QSFP+ switch or adapter ports, allowing network administrators to expand a single 40Gbps port into four separate 10Gbps connections. It works well in environments where multiple 10Gbps devices need to connect to a high-speed uplink, such as blade enclosures, storage fabrics, or top-of-rack switches. The cable’s copper construction supports reliable signal transmission over short distances without the complexity of fiber optics.

Ideal uses and environments

The Dell 462-3641 fits well in data centers and enterprise networks that require high-bandwidth, low-latency connections within racks or between adjacent racks. It is a strong choice for IT teams looking to streamline cabling in dense server setups or to build out storage networks with predictable performance. This cable is particularly useful for environments where cost efficiency and ease of deployment are priorities, offering a practical alternative to fiber optic solutions.
