PCIe 5.0 M.2 NVMe Key-M Male to OCulink SFF-8611 SFF-8612 Extension Cable

The PCIe 5.0 M.2 NVMe Key-M Male to OCuLink SFF-8611/SFF-8612 Extension Cable is a premier high-performance interconnect solution engineered for the most demanding data transfer applications. This cable assembly directly bridges the internal PCIe 5.0 lanes from a standard M.2 NVMe slot to an external OCuLink SFF-8611 (4i) or SFF-8612 (8i) interface, delivering unprecedented external bandwidth. By fully leveraging the PCIe 5.0 specification, it doubles the data rate of previous generations, making it an ideal solution for connecting external computational accelerators, all-flash storage arrays, or high-speed network interfaces. The cable is designed with a focus on superior signal integrity to ensure stable operation at extreme frequencies. This component is supplied without a mounting bracket, offering maximum flexibility for custom integration into proprietary chassis, existing systems with pre-cut openings, or open-air test benches where a standard bracket is not required.

Features

• PCIe 5.0 High-Speed Performance: Fully supports the PCIe 5.0 standard, enabling data rates up to 32 GT/s per lane for maximum external bandwidth.
• 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, facilitating high-speed external device connectivity.
• Four-Lane (x4) Bandwidth: Utilizes all four PCIe lanes from the host M.2 slot, providing a full x4 link to the connected peripheral device.
• Optimized Signal Integrity: Constructed with premium, low-loss coaxial cables and precise impedance control to maintain signal clarity and minimize insertion loss, ensuring reliable data transmission at PCIe 5.0 speeds.
• Secure Locking Connector: The OCuLink connector features a robust locking mechanism that prevents accidental disconnection, safeguarding data integrity in critical applications.
• Flexible Integration: The cable-only design allows for versatile installation in custom enclosures, open-frame systems, or scenarios where a standard PCI bracket is not applicable.
