PCIe 4.0 M.2 NVMe Key-M Male to OCulink SFF-8611 SFF-8612 Extension Cable

The PCIe 4.0 M.2 NVMe Key-M Male to OCuLink SFF-8611/SFF-8612 Extension Cable is a high-performance interconnect solution designed to externalize the full bandwidth of a modern M.2 slot. This cable assembly creates a direct bridge from an internal PCIe 4.0 x4 M.2 Key-M connector to an external OCuLink SFF-8611 (4i) or SFF-8612 (8i) interface, providing a robust and secure high-speed connection for external peripherals. Supporting data rates up to 16 GT/s per lane, it delivers substantial bandwidth suitable for demanding storage and computational applications. This cable-only version offers maximum flexibility for integration into custom chassis, existing systems with pre-configured openings, or open-air test benches where a standard PCI bracket is not required. It is an ideal solution for users seeking to connect external NVMe storage arrays, GPU enclosures, or other high-speed devices while utilizing the readily available M.2 slot on their motherboard.

Features

• High-Speed Data Transfer: Fully compliant with PCIe 4.0 specifications, supporting data rates up to 16 GT/s per lane for high-bandwidth applications.
• Direct Interface Conversion: Provides a direct path from an internal M.2 Key-M (PCIe) slot to an external OCuLink SFF-8611/SFF-8612 port, enabling flexible external device connectivity.
