Photonics
driver a named mechanism, not a conclusion
Copper reach fails at Kyber-class speeds, so scale-up bandwidth migrates from cable and pluggable optics to co-packaged optics on the substrate.
The path
| node | effect |
|---|---|
| Co-packaged optics | +0.35 |
| Optical Transceivers (800G/1.6T pluggables) | +0.35 |
| Copper | +0.35 |
| Indium phosphide (InP) | +0.35 |
| Silicon Photonics | +0.35 |
| Package shoreline (perimeter and cross-section contention between power, memory and data) | +0.35 |
coverage
6 of 6 declared anchors resolve in the model. A driver is a named mechanism rather than a graded severity or a priced claim, so its effects are deliberately smaller than either.
Arguments about this mechanism
These name its subject — they are claims about this mechanism, and they are what the eligibility gates grade.
Arguments that run through it
These name a node on the path rather than the subject, so they pass through this mechanism without being about it. Shown separately and never graded as claims about it — hubs above the graph’s own 90th-percentile degree are excluded, or every argument touching NVIDIA would attach to every mechanism NVIDIA touches.
- Co-packaged optics transfers margin to substrate integrators, not optics specialists
- Transceiver margin expansion is a mirage: buyer concentration at 1.6T resets pricing power the market prices as durable
- Package Perimeter Arbitrage: Optics Suppliers Capture Value NVIDIA Cannot Retain
- Silicon cannot emit light — indium phosphide is the chokepoint CPO relocates but cannot remove
- The Upstream Is Single-Sourced and Unpriced
