p13

• Specs and design package submission Sept 2026 • Where to find additional information: IceCube and IcePack – www.celestica.com 1. The industry should advance the copper cable technology for future generation high speed interconnect designs. 1. Rack level interconnect technology at its limits on current 100T platforms, enabling dense next gen network will require innovation in L11 fiber management, cable backplanes, optical backplanes. Call to Action
