Lenovo 4X97A81828 1.5M OSFP800 to 2x OSFP400 DAC | DAC Cable, Enterprise

Move traffic between an OSFP800 port and two OSFP400 ports without adding optics, patch panels, or extra power draw. Lenovo’s 1.5 m direct attach copper cable is designed for short-reach, high-density deployments where link simplicity matters as much as throughput. This cable is a practical fit for modern leaf-spine fabrics, aggregation layers, and GPU-adjacent switching where 800G-to-dual-400G breakout is required. By keeping the connection passive and direct, it helps reduce latency and removes the operational overhead of managing separate transceivers and fiber assemblies. For infrastructure teams, the value is in the details: fewer components to source, fewer failure points to track, and a cleaner path to predictable rack-level connectivity. When you need a short cable that matches the port architecture of current-generation switching hardware, this Lenovo DAC delivers the right physical interface for the job.
