Corning builds three factories to supply Nvidia with advanced fiber optics

Corning will open three new advanced manufacturing units in Carolina of Norte and Texas dedicated exclusively to optical technologies for Nvidia. The agreement, announced this Wednesday, provides for investment of up to US$2.7 billion by the semiconductor company and should generate at least 3,000 jobs. The two companies did not reveal the financial values ​​of the partnership, but the market reacted with optimism: Corning shares rose 10%, while Nvidia shares gained more than 4%.

The agreement allows Nvidia to acquire an equity stake in Corning through warrants to purchase up to 15 million shares at $180 each, a price above Tuesday’s close of $162.10. Além In addition, the chipmaker has pre-funded rights to purchase up to 3 million common shares for US$500 million in total.

Tecnologia optics replace copper in AI systems

The partnership implements so-called co-packaged optics, a technology that aims to replace copper cables with glass optical fibers within rack-scale artificial intelligence systems themselves. Fiber cables are tiny glass filaments that transmit data as photons at much higher speed and with drastically lower energy consumption compared to traditional copper wires.

Segundo Wendell Weeks, CEO of Corning, moving photons consumes between five and 20 times less energy than moving electrons. The executive explained in January that optical fiber allows “to bring the light conversion process very close to the computer chip”, significantly reducing energy losses. Optical fibers also guarantee less signal loss than copper, speeding up communication and reducing the distance required between hundreds of thousands of GPUs in a data center.

Jensen Huang, CEO of Nvidia, stated at the 2025 GTC conference that integrated optical components are essential for the future development of artificial intelligence. The executive said in a statement that AI drives “the largest infrastructure expansion of our time and a once-in-a-generation opportunity to revitalize the American manufacturing industry.”

Crescimento driven by AI boom since 2022

Corning shares have exploded more than 250% over the past year through Tuesday, a reflection of the 175-year-old company’s successful adaptation to the age of artificial intelligence. The explosion of investment began after OpenAI’s launch of ChatGPT in 2022, which triggered a rush for new processors and systems to power advanced AI models and workloads.

Meta invested up to $6 billion in Corning in January as a major customer, aiming to expand the optical cable manufacturing plant in Hickory, Carolina from Norte — an expansion expected to create approximately 1,000 additional jobs. Essa strong demand reflects the push from technology giants like Alphabet and Meta for increasingly robust AI infrastructure to massively scale up their data centers.

Nvidia consolidated its position in the AI ​​semiconductor market long before partnering with Corning. The company’s share price has increased about 14 times in the last five years. Porém’s rally has recently slowed as investors have diversified their investments across a broader range of AI infrastructure companies, including Intel, Micron and Corning itself. Analistas has long awaited the large-scale implementation of co-packaged optics, which promises to dramatically increase data transfer speeds and reduce power needs of AI workloads.

Competição accelerated by integrated optical technology

Nvidia has already started moves to strengthen the optical ecosystem. In March, it invested US$4 billion in two companies, Coherent and Lumentum, which develop lasers and components to convert data between light and electrical signals, then transmitted via Corning’s fiber optic cables.

Competidores also advance quickly. In 2025, Nvidia launched two network switches using similar optical technologies, positioned close to the main AI chips. Broadcom and Marvell presented similar products in the same period, while Intel develops its own integrated optical solutions. Esse accelerated competition scenario puts pressure on the entire optical component supply chain for faster innovation.

Vlad Galabov, an analyst covering enterprise infrastructure at research firm Omdia, highlighted that “Nvidia has driven the entire ecosystem to innovate faster.” Conforme the number of GPUs in a server increases into the hundreds, according to Weeks, “the distances will increase, and when those distances increase, fiber optics will become much more cost-effective and much more power efficient.”

Capacidade optical production will be multiplied tenfold

The three new factories will increase Corning’s optical production capacity tenfold in the US alone. The company is known for making all the glass for Apple’s iPhone screens, but optical communications remains its largest and most dynamic business. Desde the invention of fiber optics for long-distance communication in 1970, Corning provides millions of kilometers of cable to connect racks in artificial intelligence data centers of all the major players in the market.

Nvidia AI systems, like the Vera Rubin, currently contain approximately 5,000 copper cables. Fiber optic integration could replace a substantial portion of this copper infrastructure with more efficient technology. Durante factory visit In January, Weeks revealed to CNBC that it was working with “all the different chip experts on the glass core and how glass will be part of semiconductor packaging in the future.”
