Nvidia partners with Corning: Optical connectivity demand in AI data centers is about to surge

```

The multi-year strategic alliance signed between Nvidia and optical fiber giant Corning reflects the industry trend of explosive demand for optical connection products in the AI data center era, and directly catalyzes the entire optical supply chain market.

On May 6, according to a previous Wallstreetcn article, Corning, the leading U.S. optical fiber company, announced a multi-year commercial and technical cooperation agreement with Nvidia. According to the agreement, Corning plans to increase its capacity for optical connectivity solutions in the U.S. to ten times the current level and expand its U.S. optical fiber capacity by more than 50%. On the day of the announcement, Corning’s stock rose 12% in a single day.

According to Wind Trading Desk, Nomura Securities analyst Yuji Matsumoto stated in a May 7 report that the core significance of the alliance is that Nvidia is proactively establishing deep ties with upstream suppliers, indicating its view that long-term demand for fiber and optical connectivity products will remain strong. This demand covers traditional scale-out scenarios and extends to scale-up applications inside server racks, as well as data center interconnect (DCI) use cases.

This collaboration marks Nvidia’s third major strategic move in the optical supply chain in recent times. On March 2 this year, Nvidia had already established multi-year partnerships with Lumentum Holdings and Coherent, with contract values reaching several billion U.S. dollars. According to Nomura, this series of moves further confirms the large-scale structural demand for optical interconnect products driven by AI infrastructure investment.

Behind the Alliance: Multi-scenario Demand Overlap, Nvidia Proactively Secures Supply Chain

Nvidia’s initiative to seek collaboration with Corning is of deep strategic significance, according to Nomura.

The optical demand for AI data centers is expanding in multiple dimensions: demand for fiber and cables in scale-out scenarios continues climbing; in scale-up, internal high-speed connectivity within racks puts increasingly strict requirements on optical connectivity solutions; and in DCI, high-bandwidth transmission between data centers is simultaneously intensifying. The resonance of multiple scenarios makes Nvidia judge it necessary to strategically lock in core suppliers to ensure capacity security for years to come.

Nomura points out that it is precisely under the expectation of this long-term demand that Nvidia has proactively forged a partnership with Corning.

Expansion Pace: Major Double Expansion of U.S. Domestic Capacity

According to the May 6 announcement, Corning’s expansion plan has two layers: optical connectivity solution capacity will increase to ten times the current level; optical fiber capacity will rise by more than 50%. All these expansions target U.S. domestic production bases, and specific implementation timelines have not yet been disclosed.

Nomura data shows that major Japanese cable companies are also simultaneously pushing large-scale capacity expansion. Sumitomo Electric Industries plans to increase MT ferrule capacity to seven times the level of fiscal 2024; Fujikura is continuously increasing investment in optical fiber and optical connectors; Furukawa Electric is planning significant capacity growth in optical devices and high-density optical cables.

Japanese Cable Companies: Global High Market Share Lays Foundation for Benefiting

Although Corning is focusing its expansion on U.S. domestic sites, Nomura believes that major Japanese cable companies, by virtue of their leading position in multiple optical subsegments globally, are equally likely to benefit fully from overall market growth.

Among them, Fujikura already collaborates with Corning in optical connector-related fields and operates a joint venture in the U.S. Nomura points out that the landing of the Nvidia–Corning alliance could have a direct positive impact on Fujikura. Sumitomo Electric Industries holds a global market share of about 40% in submarine optical fiber, about 50% in micro ITLA, and over 50% in continuous wave laser diodes (CW-LD), especially enjoying differentiated competitive advantage in DCI applications. Furukawa Electric also stands to benefit from overall market demand growth.

Nomura gives a buy rating to these three Japanese cable companies.

Industry Trend: Tech Giants Accelerate Lock-in to Optical Supply Chain

From a broader perspective, the Nvidia-Corning collaboration marks the latest embodiment of the trend of tech giants speeding up their lock-in to the optical supply chain.

According to Nomura’s summary, since 2026 alone, Corning has signed multi-year agreements with Meta Platforms (worth up to $6 billion, signed in January), two unnamed hyperscale cloud service providers (April 28), and Nvidia (May 6), covering optical fiber, optical cables, and optical connectivity solutions. Prysmian also announced on April 30 a 3–7 year agreement with a hyperscale cloud service provider.

The intensification of long-term contract signing pace is becoming a structural feature of the optical product supply chain amid the wave of AI infrastructure investment, providing greater long-term visibility for related companies’ revenue.
