At the time of the transition from the information economy to the AI driven “thinking economy”, the US fiber optic industry is experiencing the largest wave of capital investment in history. Billions of dollars are pouring into fiber manufacturing, with more funds locked into long-term supply agreements, deploying massive amounts of new fiber nationwide, and creating thousands of new jobs in the southern United States.
The fiber consumption of AI projects has surged
The consumption of fiber optic cables in AI projects is 16 times higher than before – from servers to racks, racks to racks, buildings within the park to buildings, regional and metropolitan area connections, intermediate miles to long-distance transmission, all require fiber optic connections between AI and users, AI and AI.
Cloud service providers and operators lock in long-term supply
Meta and Corning signed a $6 billion multi-year agreement in January 2026, which includes the construction of a new fiber optic cable manufacturing plant in Hickory, North Carolina and the expansion of Corning’s North Carolina operational capacity, supporting Corning’s skilled worker growth of 15-20% to over 5000 people in the state. Amazon signed a multi-year, multi billion dollar agreement with Corning in June to create 1000 jobs and hundreds of construction jobs and training programs.
Lumen, Verizon and other operators have signed long-term procurement agreements. Zayo joined in August and plans to add 15000 routing miles by 2030, calling it “one of the largest network expansions in history”.
The fiber optic demand at the server level extends inward
In May, Nvidia and Corning announced a multi-year business and technology partnership, with Nvidia investing $3.2 billion, Corning adding three AI factories and at least 3000 jobs, and expanding US light manufacturing capacity tenfold. The total amount of Corning’s public agreement is approximately $11-13 billion.
Earlier this year, Japan’s Fujikura announced an investment of $1.6 billion to increase South Carolina’s fiber optic cable production capacity by approximately four times for the 2022 fiscal year. Prysmian announced in August that it will invest over $1 billion to expand its tri state factory, secure a $6.4 billion ten-year purchase agreement with Molex, make an advance payment of approximately $640 million, and create 600 new jobs. Lightera also joined the expansion wave in August.
Operators promote network upgrades
Google purchases Verizon for over $1 billion in dark fiber routing to connect data centers. Verizon expects to announce more transactions before the end of the year, generating “billions of dollars” in revenue in the coming years. AT&T plans to invest over $250 billion by 2030 to build and modernize its network, replacing copper cables with fiber optic cables.
Fiber optic, as the “nervous system” of AI, provides unlimited scalable bandwidth, low latency, and high reliability, which is the fundamental support for the “thinking economy”.
