Why it matters

The strategic read

Makes optical connectivity a contracted AI-infrastructure bottleneck, not just a theme. Customers are prepaying to reserve Tower silicon-photonics capacity for pluggable optics, near-packaged optics, co-packaged optics, and scale-out/scale-up AI networking architectures.
