Keep high-speed links simple, predictable, and cost-efficient with this 4 m SFP28 direct attach copper cable. Designed for 25 GbE environments, it connects SFP28 ports directly without separate optics, reducing component count and simplifying deployment in dense racks. At 4 m, this cable is well suited for short-reach interconnects between adjacent equipment in the same cabinet or neighboring racks. That makes it a practical fit for top-of-rack switching, server aggregation, and storage connectivity where latency, power draw, and budget all matter. HPE compatibility helps it slot into existing infrastructure planning with less friction. For teams standardizing on 25 GbE, DAC remains one of the most efficient ways to build short-distance links. It avoids the added cost and management overhead of transceivers and fiber patching while preserving the performance profile expected in modern data center fabrics. This is the kind of cable you choose when the link must be dependable, the path is short, and the deployment needs to stay clean.
