3M Twin Axial PCI Express Cable Assembly & Extender Assemblies
3M™ Twin Axial PCI Express Cable Assemblies are engineered to meet the rigorous demands of high-speed data transfer in modern computing environments. Designed for PCIe® 3.0, 4.0, and 5.0 applications, these assemblies support data rates up to 16 GT/s for generations 3.0 and 4.0 and up to and up to 32 GT/s for generation 5.0, ensuring efficient performance for bandwidth-intensive tasks-up to 64GB. The innovative design features foldable, flexible twin axial ribbon cables, allowing for versatile routing and compact system configurations without compromising signal integrity. Continuous longitudinal shielding virtually eliminates crosstalk and insertion loss, even when the cable is bent or folded, making it ideal for space-constrained applications. Available in x4, x8, and x16 configurations, these assemblies offer compatibility with various PCIe® form factors, providing designers with enhanced flexibility to optimize system packaging and airflow. Whether used as riser cables, mid-board connections, or board-to-board links, 3M's Twin Axial PCI Express Cable Assemblies deliver reliable, high-performance solutions for today's advanced computing needs.
The new Gen 5.0 Extender is enhanced for higher signal integrity and data rates.
