Lenovo 3m Passive DAC SFP+ Cable

The Lenovo 90Y9430 is a direct attach copper cable that spans three meters and ends with a pair of SFP+ plugs, giving network teams an easy way to establish a 10-gigabit link between nearby devices. Because the cable is passive, it has no active circuitry and relies entirely on the switch or network adapter to maintain signal quality, which helps reduce power consumption and simplify maintenance.

This cable fits naturally in dense data center racks where servers, top-of-rack switches, and storage arrays sit only a few meters apart. Administrators can use it for tasks such as server clustering, virtual machine migration, or rapid backups when low latency and high throughput are required without the cost of optical modules.

Installation is straightforward: connect the SFP+ end of each side to compatible 10 GbE ports and the link comes up automatically. There is no firmware to update and no modules to match, so spare inventory stays lean and downtime during cable swaps remains minimal.

Highlights:

• A three-meter cable built with direct attach copper
• SFP+ male connectors on both ends for 10 GbE ports
• Supports 10 Gbps 10GBase transmission
• Passive design with no active electronics or added power draw
• Ideal for short-distance links within or between racks in a data center
