Nvidia highlights role of optical networking as Coherent breaks ground on Texas AI chip facility

Coherent’s new Sherman, Texas facility marks a strategic pivot toward localized optical interconnect supply chains, driven by AI’s insatiable bandwidth demands. Technically, this accelerates the commercialization of silicon photonics and co-packaged optics (CPO), forcing foundries like TSMC and Intel to fast-track hybrid photonic-electronic integration. Under U.S. CHIPS Act stipulations, mandated domestic content thresholds (>50%) raise near-term capex but mitigate geopolitical supply shocks—optical components are now a stealthier yet more critical choke point than logic chips amid U.S.-China tech decoupling. Competitively, while Lumentum and Coherent dominate, Taiwan, China’s Innolume and Hong Kong, China’s Viavi are leveraging HBM-AI co-design to infiltrate high-end markets. Nvidia’s upstream investments signal that optical engine capacity—not GPU count—will dictate AI cluster deployment velocity over the next 18 months.
