Zayo announced its largest mobile infrastructure contract to date, but did not disclose the customer or financial terms.
Zayo will upgrade and expand the customer’s fiber-to-the-tower (FTT) network, which includes dark fiber to more than 1,800 cell sites in 26 markets across the U.S. With this expansion, Zayo’s FTT network will surpasses an estimated 10,000 cell sites nationwide, including those under construction.

“The power of second tenant economics is demonstrated through this award, including where the other tenants are from a variety of verticals, such as content providers, technology companies, traditional enterprises and school districts,” added Chris Morley, chief operating officer at Zayo. “The financial merits of a multi-tenant platform will become even more compelling as wireless carriers move toward small cell, 5G and CRAN.”
