Everything on Networking

The transition from copper to optical networking is inevitable for scale-up AI clusters, driven by the physical limitations of copper at high speeds. The industry is expected to adopt co-packaged optics by 2028-2029, fundamentally changing cluster architecture.

Impact: Companies investing in optical supply chains and co-packaged optics will gain a competitive advantage in building efficient, large-scale AI infrastructure.
