Can high-speed copper cable connections surpass optical modules in the future

At the GTC 2026 conference, Nvidia CEO Jensen Huang explicitly corrected the market misconception of "optics replacing copper," stating that copper cables remain indispensable inside AI server racks due to their physical advantages like zero power consumption and low. At the GTC 2026 conference, Nvidia CEO Jensen Huang explicitly corrected the market misconception of "optics replacing copper," stating that copper cables remain indispensable inside AI server racks due to their physical advantages like zero power consumption and low. Held March 17–19 at the Los Angeles Convention Center, the show brought together the global optical communications ecosystem at a critical inflection point: Artificial Intelligence (AI) is fundamentally reshaping how data centers are built and the race to scale is pushing interconnect technology to. Today, links are running at 1 Tbps over optical, or 10,000 times faster than cutting edge speeds two decades ago. 6T performance, the humble connector and the sophisticated optical transceiver have become strategic assets. This article explores how the AI infrastructure boom is reshaping networking, and how LINK-PP — long recognized for its excellence. SAN JOSE, California – Nvidia confirmed its next generation of networking technologies for scale-up and scale-out will support both copper and co-packed optics (CPO). Industry concerns over speeds, costs, and a supply deficit projected to kick in by 2040 have seen copper's industry relevance. Co-packaged copper is yet another option for building switch, GPU and accelerator connectivity.
