Zayo expands LH dark fiber and 400G routes, upgrades IP core with Juniper

Zayo announced a series of expansions and enhancements to its network and services, including significant growth of its long-haul dark fiber and 400G-enabled routes and modernization of its IP core network. Juniper was selected for the IP core upgrade.

“The only way to stay ahead of the digital curve is to continuously transform. Transformative ideas need a reliable, resilient and on-demand network,” said Bill Long, Chief Product Officer at Zayo. “Zayo is leading the industry with network automation and self-service options, ensuring customers have unprecedented speed and resilience with more flexibility and elasticity, while enhancing security and value, so our customers can focus on making progress toward their business goals instead of worrying about their network.”

Zayo is launching Waves on Demand to enable same-day turn-up on the most in-demand routes, with significantly shortened delivery times. Customers can quickly provision “Wavelength on Demand” between key data center locations across its market-leading network footprint, including its highest-demand routes.
