Lenovo 3m Passive DAC SFP+ Cable

Overview

The Lenovo 90Y9430 is a 3-meter passive direct attach copper (DAC) cable designed to establish reliable 10-gigabit Ethernet connections between devices in close proximity. It features SFP+ connectors on both ends, making it an efficient solution for linking servers, switches, and storage arrays within dense data center environments. Its passive design means it does not contain active electronics, which reduces power consumption and simplifies maintenance.

This cable is well suited for applications requiring low latency and high throughput, such as server clustering, virtual machine migration, and rapid backups. Installation is simple, with plug-and-play connectivity that requires no firmware updates or module matching, helping to minimize downtime and keep spare inventory manageable.

Key features

• Direct attach copper construction that provides a cost-effective alternative to optical modules for short-distance connections
• SFP+ male connectors compatible with 10 GbE ports for straightforward integration into existing network hardware
• Passive design eliminates the need for active circuitry, reducing power draw and potential points of failure
• Supports 10 Gbps 10GBase transmission speeds, ensuring fast and stable data transfer
• Ideal for short links within or between racks, fitting naturally in dense data center setups
• Plug-and-play installation with no firmware or module compatibility concerns, simplifying network management

Key specs

• Cable length: 3 meters
• Connector type: SFP+ male on both ends
• Data rate: 10 Gbps (10GBase)
• Cable type: Passive direct attach copper
• Power consumption: None from the cable itself due to passive design

Connectivity and compatibility

This cable is designed to connect devices equipped with SFP+ ports supporting 10 GbE speeds. It works well in environments where devices are located within a few meters of each other, such as within the same rack or adjacent racks in a data center. Its passive nature means it relies on the connected switches or network adapters to maintain signal integrity, so compatibility with standard 10GBase SFP+ ports is essential.

Installation and setup

Setting up the Lenovo 90Y9430 is straightforward. Simply plug each SFP+ connector into the corresponding 10 GbE port on your devices. The link will establish automatically without the need for firmware updates or additional configuration. This ease of installation helps reduce downtime during maintenance or upgrades and keeps spare parts inventory simple.

Ideal uses and environments

This cable is a strong choice for data centers and enterprise environments where short-distance, high-speed connections are needed between servers, switches, and storage units. It fits well in dense rack configurations and supports critical tasks that demand low latency and high throughput, such as virtual machine migration and clustered server operations. Its passive design also makes it suitable for setups where minimizing power consumption and simplifying maintenance are priorities.
