Aruba R0M47A 50G SFP56 to SFP56 3 m DAC Cable

Build short-reach 50 GbE connections with a direct attach copper cable designed for SFP56 ports on both ends. The 3 m length is ideal when switches, servers, or aggregation gear sit within the same rack or immediately adjacent cabinets, giving you a compact path that is easy to route and simple to maintain. For teams designing dense network fabrics, DAC remains a practical choice because it removes the need for separate optical modules on each end of the link. That means fewer components to source, fewer points of failure, and a cleaner bill of materials for high-port-count deployments. The shorter 3 m run also helps keep cable slack under control in tightly packed racks. This Aruba cable fits environments where 50 GbE connectivity must be fast to deploy and consistent to operate. It is well suited to top-of-rack switching, leaf-spine adjacency, and other short-distance interconnects where direct attach copper provides the right balance of speed, simplicity, and cost control.
