Zayo Locks Up Corning Fiber Capacity for AI Network Buildout

A telecommunications firm has secured manufacturing capacity with a fiber optic supplier to ensure it has enough fiber for expanding its network by thousands of route miles through 2030. The agreement matters because fiber availability has become a physical constraint for building artificial intelligence data center infrastructure, alongside power and other resources, and long-term supply commitments help protect construction schedules that take years to complete. The expansion is being driven by demand from artificial intelligence operations that require much higher volumes of data transfer between facilities than traditional network traffic, as well as the need for multiple diverse routes to prevent outages. The physical infrastructure requirements for AI are creating demand in new geographic markets beyond traditional telecommunications hubs, requiring companies to plan manufacturing and construction years in advance.
