Digital infrastructure provider Zayo has partnered with Nvidia to construct over 8,000 miles of new long-haul fiber across North America. This project aims to support AI corridors, GPU clusters, and hyperscaler deployments by addressing network-capacity gaps.

To support its broader expansion goals, Zayo has expanded a strategic supply agreement with Corning Incorporated. This deal is intended to secure fiber optic cable through the end of the decade, mitigating material shortage risks as Zayo plans to add 15,000 new route miles by 2030.
