Aruba HPE R0Z25A 100G QSFP28 DAC Cable 1 m | Direct Attach, Enterprise

Preserve high-speed connectivity between nearby switches, servers, and storage with a 1 m QSFP28 direct attach copper cable. Designed for short-reach 100G links, it removes the need for separate optical transceivers on both ends, helping reduce cost, power consumption, and rack complexity. This cable is a practical fit for top-of-rack and adjacent-rack deployments where latency, cable management, and budget all matter. The fixed 1 m length supports tidy routing in dense enclosures and minimizes excess slack that can obstruct airflow or service access. For infrastructure teams standardizing on QSFP28-based 100G fabrics, DAC is often the most efficient choice when the connection distance stays short. Use it where predictable, point-to-point performance matters more than long-reach flexibility. It is well suited to environments that need dependable 100G interconnects without paying for optics that are not required at this distance.
