Zayo has completed a new fiber route in the western US.

The company last week announced the completion of its Umatilla-Prineville-Reno (UPR) long-haul fiber route, a 622-mile (1,000km) corridor between Oregon and Nevada.

Built with SMF-28 fiber, multiple conduits, and 13 Zayo-owned in-line amplifier (ILA) sites, the company said the route is engineered for low latency and high fiber count to support AI and cloud workloads.

“While others plan, we’re building the infrastructure that makes AI possible,” said Bill Long, chief product and strategy officer at Zayo. “Without connectivity, data centers and AI factories are just expensive refrigerators: cold boxes of compute with no way for data to get in or out. We’re delivering the capacity and reach where it’s needed to ensure AI can work, scale, and innovate without limits.”

The project was funded in part by the NTIA Middle Mile Grant Program.

Founded in 2007, Zayo has some 148,000 route miles (238,182km) and 19.5 million fiber miles (31 million km) connecting some 1,700 on-net data centers in operation. Earlier this year, the company announced plans to build 5,000 new long-haul route miles by 2030.

Zayo went public in 2014 and was taken private by global investment firms EQT AB and Digital Colony Partners (now DigitalBridge) in a deal valued at $14.3 billion at the time.
