Meta's Petal subsea cable project and Corning's massive fiber supply deals underscore a critical industry pivot toward private, high-speed physical infrastructure to support the next generation of AI model training.
Corning is the primary fiber and cabling supplier for Meta's up to $6 billion AI data-center buildout and Verizon's 80 million fiber-mile network, creating strong multi-year revenue visibility despite a rich valuation.
Meta's Petal subsea cable and $6B Corning supply agreement support long-term AI infrastructure ambitions, but a recent earnings miss and regulatory hurdles temper near-term sentiment.
Lumentum's collaboration on optical die-to-die connectivity at ECOC 2026 positions it to benefit from the AI-driven shift from copper to optical interconnects.
Verizon's long-term agreement to purchase more than 80 million fiber miles through 2032 supports its network modernization but represents significant capital commitments.
Qualcomm demonstrated 1060 nm optical die-to-die connectivity with Corning and Lumentum, highlighting its role in AI intra-rack optical interconnects.
NEC is a specialized partner in Meta's Petal subsea cable project, providing submarine cable technology expertise.
Sumitomo Electric Industries is named as a partner supplying two-core optical fiber technology for Meta's Petal cable.
Meta Platforms has announced Petal, a 7,000-kilometer petabit-scale subsea cable connecting the U.S. and France, set for 2029. This project highlights a strategic shift by hyperscalers to build private global networks, with Corning Incorporated emerging as a primary beneficiary through a $6 billion supply agreement and extensive fiber-mile contracts.
Meta is building the Petal cable to ensure low-latency, high-throughput data transfer for distributed AI model training, effectively bypassing the bandwidth throttling and pricing unpredictability of public commercial carriers.
As copper wiring reaches its physical limits for data transfer, the industry is transitioning to optical interconnects. Companies like Corning provide the fiber backbone, while Lumentum and Qualcomm collaborate on optical die-to-die connectivity to maintain speed within server racks.
