Keep 400 GbE links direct, compact, and easy to manage with this 3 m direct attach copper cable. Built for short-reach interconnects, it is a practical choice for switch-to-switch or switch-to-server connections where optical modules would add cost and complexity. The Arista compatible design supports infrastructure teams standardizing on high-density 400G deployments. A 3 m reach gives enough flexibility for adjacent racks or within-row cabling while still preserving the clean cable paths that matter in modern data centers. For teams planning around airflow, serviceability, and port density, DAC remains one of the most efficient ways to connect high-speed equipment. This cable is well suited to environments that need predictable short-distance performance and straightforward installation. It reduces the number of components in the link, helping simplify troubleshooting and inventory management. For organizations investing in 400G switching, it delivers the kind of direct, purpose-built connectivity that supports serious production workloads without unnecessary overhead.
