Context Before

While 448G high speed SerDes have big challenges for shoreline, reach, and power versus using a die-to-die connection to an optical engine, the manufacturing challenges, cost, and reliability for Feynman necessitate using copper to the Switch.

With that said, the NVL1152 SKU is years out – and the roadmap is highly likely to shift. For now, our base case stands at copper being used within each rack and CPO between the racks, but this could easily change.

Evidence

For now – our best estimate of Nvidia’s CPO roadmap is as follows:
