Lumen Technologies has been diligently responding to business needs for more network capacity and has now created the largest ultra-low-loss fiber network in the world. But Lumen isn’t stopping there. The company plans to invest in another six million fiber miles which is expected to be installed by 2026.

"We are creating a next-gen network, and fiber type matters," said Andrew Dugan, Lumen’s chief technology officer. As demand for optical fiber increases and technology evolves, Lumen's multi-conduit infrastructure means we can install the latest fiber type quickly and economically.”

Once complete, this U.S. intercity investment will extend nearly 12 million fiber miles, creating diverse routes to more than 50 major cities across the country. Lumen has set this network apart from others by upgrading its infrastructure using a multi-conduit system, allowing for the quick deployment of the latest fiber technology.

"It's difficult to upgrade legacy intercity networks without multiple conduits," said Dugan. “Lumen is fixing that issue with our upgraded technology. We can extend signal reach to help reduce equipment costs and increase bandwidth capacity."

With 400,000 route miles of fiber, Lumen serves customers in more than 60 countries, delivering a fast, secure platform to give businesses, government and communities amazing experiences. Lumen is continuing to use the latest in optical technology, and has upgraded over 24,000 route miles across its U.S. intercity network. This fiber technology can support up to 400G now and helps businesses meet high bandwidth needs and analyze their data in real-time.
