The multi-year strategic alliance signed between NVIDIA and optical fiber giant Corning reflects an industry trend that demand for optical connectivity products is poised to surge massively in the AI data center era, while delivering direct market catalysts to the entire optical supply chain.

On May 6, per earlier reports from Wall Street CN, U.S. optical fiber leader Corning announced a multi-year commercial and technical cooperation agreement with NVIDIA. Under the deal, Corning plans to expand its production capacity of optical connectivity solutions in the United States to ten times the current level, and boost its domestic optical fiber capacity by more than 50%. Corning’s share price rallied 12% in a single trading day following the announcement.

According to market information from Zhuifeng Trading Desk, in a research note dated May 7, Nomura Securities analyst Yuji Matsumoto stated that the core implication of this alliance lies in NVIDIA’s initiative to forge deep ties with upstream suppliers, underscoring its view that long-term demand for optical fibers and optical connectivity products will remain robust. Such demand covers not only traditional scale-out scenarios, but also extends to scale-up within server racks and Data Center Interconnect (DCI), among other application areas.

This collaboration marks NVIDIA’s third major strategic layout in the optical supply chain recently. On March 2 this year, NVIDIA inked multi-year partnerships with Lumentum Holdings and Coherent respectively, with each contract valued at billions of U.S. dollars. Nomura commented that this series of moves further validates the structural large-scale demand for optical interconnect products driven by AI infrastructure investment.

Behind the Alliance: Overlapping Multi-scenario Demand Drives NVIDIA’s Proactive Supply Chain Lock-in

Nomura noted that NVIDIA’s proactive push for cooperation with Corning carries far-reaching symbolic implications.

Optical demand for AI data centers is expanding across multiple dimensions: demand for optical fibers and optical cables continues to climb in scale-out scenarios; scale-up applications impose increasingly stringent requirements on high-speed intra-rack optical connectivity solutions; meanwhile, demand for high-bandwidth transmission across data centers is also on the rise. Fueled by the resonance of multiple scenarios, NVIDIA deems it strategically necessary to lock in core suppliers to secure capacity supply for years ahead.

Driven by such long-term demand expectations, NVIDIA has taken the initiative to establish a cooperative relationship with Corning, according to Nomura.

Capacity Expansion Pace: Dual-track Massive Expansion of U.S. Domestic Production Capacity

Per the official announcement on May 6, Corning’s capacity expansion plan unfolds on two fronts: its production capacity for optical connectivity solutions will be scaled up to ten times the existing level, while optical fiber capacity will grow by over 50%. All aforementioned expansions target its U.S. manufacturing bases, with specific implementation timetables yet to be disclosed.

Meanwhile, major Japanese cable manufacturers are also pressing ahead with large-scale capacity expansion, according to Nomura’s data. Sumitomo Electric Industries plans to raise its MT ferrule capacity to seven times the level of fiscal 2024; Fujikura continues to ramp up investment in optical fibers and optical connectors. Furukawa Electric has also mapped out substantial capacity growth in optical devices and high-density optical cables.

Japanese Cable Manufacturers: Global High Market Share Lays Foundation for Industry Benefits

While Corning centers its capacity expansion on U.S. domestic facilities, Nomura believes major Japanese cable players are well-positioned to fully benefit from overall market growth, leveraging their leading positions in multiple global optical market segments.

Among them, Fujikura already maintains a cooperative relationship with Corning in optical connector businesses and operates joint ventures in the United States. Nomura pointed out that the NVIDIA-Corning alliance is likely to deliver direct positive impacts to Fujikura. Sumitomo Electric Industries holds global leading market shares in segmented tracks including submarine optical fiber (roughly 40% global share), miniature ITLA (around 50%), and continuous-wave laser diodes (CW-LD, over 50%), boasting differentiated competitive advantages especially in DCI scenarios. Furukawa Electric is also expected to benefit from rising overall market demand.

Nomura maintains Buy ratings on the three major Japanese cable manufacturers mentioned above.

Industry Trend: Tech Giants Accelerate Lock-up of the Optical Supply Chain

From a broader perspective, the NVIDIA-Corning partnership represents the latest manifestation of the trend where tech giants are speeding up efforts to secure optical supply chain resources.

As compiled by Nomura, since the start of 2026 alone, Corning has signed multi-year agreements successively with Meta Platforms (a deal worth up to $6 billion in January), two unnamed hyperscale cloud service providers (April 28), and NVIDIA (May 6), covering full product lines including optical fibers, optical cables and optical connectivity solutions. Prysmian also announced a 3-to-7-year contract with a hyperscale cloud provider on April 30.

The accelerating pace of long-term contract signing has become a structural feature of the optical product supply chain amid the AI infrastructure investment boom, delivering stronger revenue visibility for relevant enterprises in the long run.
