Zayo Announces 400G Availability on Dark Fiber Routes
Briefly

Zayo has initiated the construction of three dark fiber routes to support artificial intelligence (AI) needs, totaling 1,029 miles. The routes include a 385-mile connection from Chicago to Columbus, a 521-mile link between Chicago and Minneapolis, and a 123-mile high-capacity route from Phoenix to Tucson. The company's North American core network has been upgraded to 400 Gbps, adding significant optical capacity and expanding IP networks with new points of presence. Zayo has also enhanced its fiber monitoring capabilities and introduced new Quick Connect Data Centers.
AI requires scale at an order of magnitude greater than any technology we've seen before," said Bill Long, Zayo chief product and strategy officer, in a prepared statement about the dark fiber routes.
This 385-mile, low-latency fiber route between Chicago and Columbus is designed to support high-throughput, AI-driven workloads by providing connectivity to all major data centers in both cities.
The planned construction of a 123-mile high-capacity fiber route between Phoenix and Tucson will connect data centers in one of the Southwest's fastest-growing AI corridors.
Completed the full 400G upgrade of its North American core network to deliver high-capacity, low-latency infrastructure, added 393.6 terabits of optical capacity.
