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

The PCIe 4.0 M.2 NVMe Key-M Male to OCuLink SFF-8611/SFF-8612 Extension Cable with Half-height Bracket is a specialized high-speed adapter designed for compact and space-constrained computing environments. This cable assembly effectively externalizes the high-bandwidth capabilities of an internal M.2 NVMe slot by converting it to an OCuLink SFF-8611 (4i) or SFF-8612 (8i) interface, fully compliant with the PCIe 4.0 standard. The defining feature of this model is its half-height bracket, which allows for seamless integration into slim-line chassis, small form factor PCs, and 1U server racks where a full-height bracket would not fit. This solution provides a robust and secure external port for connecting high-performance peripherals such as external NVMe storage arrays or specialized accelerator cards, delivering significant bandwidth for data-intensive tasks while maintaining a minimal physical footprint. It is an ideal expansion solution for compact workstations, home theater PCs, and dense server configurations.
