Zayo to expand fiber network infrastructure across the nation

(UI) – Zayo Group Holdings, Inc. announced a series of expansions to its independent fiber network infrastructure, including new long-haul dark fiber routes, increased fiber capacity for existing routes, additional 400 Gbps (400G)-enabled routes and new IP points of presence (PoPs).

“The network our future requires does not exist today. A digital-first world requires continued and intentional investment in infrastructure, of which Zayo is leading the charge. Our continued expansion and modernization of our long-haul dark fiber, wavelength, and Tier-1 IP infrastructure is critical in ensuring our customers have the speed, resilience and flexibility they need in their network to stay ahead of this increasing digital demand,” said Bill Long, Chief Product Officer at Zayo.

In April, Zayo unveiled significant plans to grow and modernize its network, including the addition of nearly 3,000 route miles and more than 700,000 fiber miles to its global network. The company has begun building these new long-haul dark fiber routes to provide its customers with diverse routing options and a customizable, robust and scalable network. The new routes are built entirely underground to provide the highest level of security and redundancy for customers.

In June, Zayo was awarded a $92.9M grant from the National Telecommunications and Information (NTIA) Middle Mile Program—the only national provider to receive funding—to expand network infrastructure to unserved and underserved communities across eight states. As part of its aggressive growth strategy, Zayo has also continued to expand its global footprint, including new connections for its high-capacity network across Europe, Mexico, and South America.

Zayo’s newest long-haul dark fiber routes include:

St. Louis to Indianapolis: Expands connectivity in these growing markets, bypassing the heavily trafficked Chicago metro area with four In-Line Amplification (ILA) sites in key markets along the route.

Chicago to Omaha overbuild: Provides the most direct route between Denver and Chicago, including a new high fiber count cable that connects 11 ILA sites in strategic markets, facilitating seamless network connections for customers. As a heavily used route, this overbuild will allow for more capacity.

Network modernization with 400G

400G routes provide better routing performance, stability, high bandwidth and reduced pricing for Zayo’s customers. The enhanced capacity from these routes supports customers with exponential growth needs driven by emerging technologies like 5G, generative AI, cloud adoption, IoT and edge computing.

With four new 400G-enabled routes made operational in the second quarter of 2023 and two more slated for completion in Q3, Zayo is expanding high-bandwidth options between key cities, including Las Vegas to Phoenix, Kansas City to Indianapolis, Dallas to East St Louis, Albany to Boston, Denver to Dallas (a direct route scheduled for completion in Q3 2023), and Atlanta to DC (scheduled for completion in Q3 2023).
