Networking and Optics Investment Thesis

Cluster scale is rewriting the networking layer. Optics, switching, and high-bandwidth fabric are becoming the visible differentiator inside AI infrastructure.

Why this matters

AI training clusters are bottlenecked on interconnect, not just compute. The economics of optics, switching, and high-bandwidth fabric are improving every quarter, and the supply chain behind them is concentrated.

Where I focus

Optical components and packaging
High-radix switching and fabric design
Co-packaged optics and integrated photonics
Specialist suppliers serving hyperscale buyers
