Zayo has reached a long-term fiber supply agreement with Corning to secure a significant portion of the optical fibre the company expects to need through the rest of the decade. The deal is aimed at ensuring Zayo has reliable access to fibre as it ramps up network expansion to meet growing demand from enterprises, AI companies and data centres.
The two companies declined to disclose the financial terms of the agreement, which was announced on Thursday.
Fibre Supply Supports Network Expansion
Zayo is planning to deploy 15,000 new route miles of fibre by 2030, including 8,000 miles linked to its agreement with Nvidia. The company’s North American fibre network currently spans 224,000 route miles.
Securing fibre supply now is a strategic move for Zayo as supply chain pressures continue to build across the telecom industry. ISPs of all sizes have reported rising costs and tighter availability of fibre, driven in large part by surging demand from AI companies. Rural broadband providers that won funding under the Broadband Equity, Access, and Deployment programme are still finding equipment more expensive than anticipated, and major carrier executives recently described supply chain costs as “skyrocketing.”
The fiber supply agreement with Corning is designed to give Zayo greater flexibility to scale its fibre infrastructure as customer demand evolves, without being constrained by material shortages.
“AI infrastructure is putting unprecedented pressure on one of the physical inputs required to scale it: fiber,” the companies said in a joint release. “Securing fiber optic cable supply now gives Zayo greater flexibility to scale as demand evolves.”
AI and Data Centres Drive Fibre Demand
The growing appetite for AI infrastructure and data centre connectivity is reshaping fibre demand across North America. Zayo provides fibre connectivity to enterprises, and increasingly to AI companies and data centres, placing it at the centre of this demand cycle.
Bob Whitman, Corning’s vice president of market development, said at Mountain Connect last week that the company was staggering fibre shipments to BEAD winners to align with deployment timelines rather than fulfilling bulk orders. This approach is intended to keep BEAD builds on schedule while also meeting demand from hyperscale customers.
A Corning spokesperson confirmed that the Zayo fiber supply agreement would not affect fibre availability for BEAD programme recipients.
Zayo’s leadership expressed confidence that the deal positions the company well. “We understand where demand is moving, and we’re putting the physical inputs in place now to build ahead of it,” the company said in a statement. “Deepening our relationship with Corning gives us greater confidence that material availability won’t stand between customer demand and the infrastructure required to deliver it.”
As AI workloads continue to expand and data centre construction accelerates, securing reliable fibre supply has become a pressing concern for network operators. This fiber supply agreement between Zayo and Corning reflects the broader industry trend of locking in physical infrastructure resources well ahead of anticipated demand, ensuring that fibre network expansion can keep pace with the rapid growth in enterprise and AI connectivity requirements.
