The HPE Aruba Networking R0M47A 50G SFP56 to SFP56 3m Direct Attach Copper (DAC) Cable is a high-speed passive twinax cable designed for short-range 50GbE connectivity in enterprise, cloud, and data center environments. Featuring SFP56 connectors on both ends and a 3-meter cable length, it provides a cost-effective, low-latency alternative to optical transceivers for interconnecting switches, servers, and storage devices.

The passive copper design minimizes power consumption while delivering reliable 50Gbps throughput. The cable is commonly used for switch stacking, top-of-rack deployments, and high-speed switch-to-switch interconnections within racks or between adjacent racks. Aruba validates the R0M47A for supported SFP56 ports on Aruba CX switch platforms.
