Based on the evidence I see in the past week, the optical story has gotten better, not worse. Scale-out CPO seem to be on track and pushing Lumentum’s revenue this quarter to the high end of their guidance. Scale up CPO was never delayed, as it was always shipping with Feynman, not Rubin Ultra, in the first place. And NPO does not cannibalize CPO. Instead, it cannibalizes the Kyber racks, making it purely incremental content for optics.

ideas
The new evidence suggests delays, thermal issues, qualification problems, or yield friction. That does not settle the winner map, but it can push out the timeline for meaningful rack-scale CPO adoption.
research
No unresolved questions from live evidence.

setups
No execution setups. This is normal; most evidence should not become a trade.
