Optical interconnect and switching are increasingly viewed as critical bottlenecks in scaling AI clusters, and the partnership expansion reinforces Fabrinet’s positioning in advanced photonics manufacturing. Fabrinet has been benefiting from AI data-center buildout demand in optical communications and related high-performance networking programs, making incremental manufacturing wins in silicon photonics especially market-moving.
