3M™ Twin Axial PCI Extender Assemblies Gen 4.0 8Kxx Series allows for extremely versatile routing and configuration while maintaining signal strength, especially in system designs with challenging board patterns. Ideal for PCIe® (85 ohm) 4.0 applications, 3M extenders feature flexible, foldable thin twin axial ribbon cables that allow for more cable without added space. This increases design capability, allows for highly efficient cable management, and helps maximize airflow for better thermal control in high-performance architectures. Extender assemblies are available in x8, x16, straddlemount and surfacemount (SMT) versions. The series meets the PCIe Gen 4.0 specification and may meet Gen 5.0 under certain conditions.
