Context Before
Source: SemiAnalysis
Optics will be required for the inter-rack connections, though strictly speaking it isn’t confirmed whether this will be with pluggable optics or with CPO, though CPO seems much more likely. The current Blackwell NVL576 prototype “Polyphe” uses pluggable optics.
Evidence
The use of pluggables contributed to an enormous increase in BOM cost that made the system untenable from a TCO perspective for a switched all-to-all
Context After
The downstream implications of this are exposed in our institutional research, trusted by all major hyperscalers, semiconductor companies, and AI Labs, at sales@semianalysis.com
