OCulink SFF-8611 4i to U.2 SFF-8639 with 15P Power Cable

The OCuLink SFF-8611 4i to U.2 SFF-8639 with 15P Power Cable is a high-performance hybrid solution designed for enterprise storage systems and data centers. This cable converts a single OCuLink SFF-8611 4i host interface to a U.2 SFF-8639 interface while integrating a separate SATA power connector, enabling simultaneous data transmission and power delivery to NVMe SSDs. It provides reliable high-speed connectivity between PCIe-based hosts and U.2 storage devices, making it ideal for storage expansion, server upgrades, and high-density deployments where both data and power need to be delivered efficiently.
