Corning expands fiber production to meet surging AI demand

The rapid expansion of artificial intelligence is driving a significant need for denser optical networks, prompting major suppliers to scale up infrastructure production within data centers. As AI models require higher data transmission speeds to support complex GPU clusters, the industry is shifting away from traditional copper-based systems toward high-density fiber-optic solutions.

Corning Incorporated reported a 44% year-over-year sales increase in its Optical Communications segment, reaching $2.38 billion in the third quarter of 2026. Within that segment, enterprise network sales saw an 84% jump. To support this growth, the company is investing $585 million to expand its manufacturing capabilities in North Carolina.

The company has secured multiyear, multibillion-dollar agreements with major partners including Nvidia, AT&T, and Verizon. The deal with Verizon alone involves the delivery of more than 80 million miles of fiber between 2027 and 2032. Mike O’Day, senior vice president and general manager of Corning Optical Communications, stated that operators must build networks today to prepare for future demands, noting that insufficient fiber can lead to performance bottlenecks such as system errors or stalled chatbots.

Industry analysts emphasize the interconnected nature of this infrastructure. Gordon Bell, a partner at EY-Parthenon, noted that the end-user experience of AI depends on the simultaneous alignment of powered data centers and connectivity. Corning management has established long-range financial targets, aiming for $30 billion in annualized sales by the end of 2028 and $40 billion by the end of 2030, with an expected acceleration in optical scale-up beginning in 2028.
