From Corning to Ciena: The 10x Opportunity in the AI Optical Communication Chain
The transition from copper to optical communication in AI data centers is creating significant investment opportunities beyond just chipmakers. The entire photonics supply chain, from glass and fiber to connectors and test equipment, is critical. Corning, a key fiber supplier, has locked in multi-billion dollar, multi-year contracts with major cloud providers (Meta, Amazon, Google, Microsoft, OpenAI, NVIDIA), demonstrating pricing power and scale. Its profit growth is outpacing revenue growth.
In the interconnect layer, Amphenol benefits from high growth in AI data centers, driven by strategic acquisitions and operational efficiency, while Credo Technology acts as a bridge between copper and optical solutions, though with high customer concentration risk.
At the systems level, Ciena enables higher data capacity on existing fiber lines, with a strong backlog and cloud customer adoption. Further upstream, AXT is a bottleneck supplier of key indium phosphide wafers for lasers but faces geopolitical supply chain risks. VEO Solutions provides essential testing equipment for the entire photonics industry.
A new pure-play photonics ETF (FOTO) offers a consolidated investment approach. The core thesis is that the physical limits of copper are driving an inevitable shift to optical technologies, with wealth flowing to essential, often overlooked, suppliers across the photonics value chain.
