At Computex 2026, MediaTek and Foxconn quietly showcased the technologies behind a coming infrastructure upheaval: the shift from copper to optical interconnects. Nvidia’s future AI systems may soon abandon thousands of copper cables altogether, replacing them with entirely new rack architectures built for the post-copper era.
From MicroLED optical transceivers to “cable-free” AI racks, this story explores the hidden battle over connectivity, power, thermals, and who will control the next generation of AI infrastructure once the copper wall is reached.
