HPE Aruba S1J08A QSFP56 to SFP56 3 m DAC Cable

Keep short-reach 50G connections simple, stable, and cost-conscious with the HPE Aruba Networking QSFP56 to SFP56 3 m DAC cable. This direct-attach copper assembly is designed for high-density environments where you want to preserve port performance without adding the cost and power draw of separate optics. At 3 meters, it fits neatly across adjacent racks, top-of-rack switches, and nearby server or appliance connections. For infrastructure teams, the value is in the details: fewer components to source, fewer failure points to manage, and a cleaner cable path in crowded cabinets. DAC is a practical choice when the link stays inside the rack row and you need predictable connectivity for 50G-class deployments. The Aruba compatibility also makes it a straightforward fit for environments standardized on HPE networking hardware. When uptime, airflow, and serviceability matter, a purpose-built DAC cable is often the right answer. It keeps the connection direct, the install fast, and the bill of materials lean without compromising the physical link between supported ports.
