CenturyLink, Inc. (NYSE: CTL) says it has completed the first of a two-phase build out that will see its fiber-optic networks in the U.S. and Europe grow by 4.7 million fiber miles. The new fiber infrastructure leverages ultra-low-loss fiber from Corning (NYSE: GLW) and will support businesses, government agencies, and other service providers who want access to fiber.

The first phase, completed in June, addressed CenturyLink’s U.S. requirements and connected more than 50 cities via 3.5 million new fiber miles. The European work, slated to finish in the first part of 2021, will see 1.2 million fiber miles installed. Both deployments leverage CenturyLink’s multi-conduit infrastructure, which the company says enables quick and economical fiber deploy and capacity expansion.

"Our newly built intercity fiber network, created with the latest optical technology, is another example of how our diverse fiber assets differentiate us from other network providers," said Andrew Dugan, CenturyLink chief technology officer. "Our multi-conduit infrastructure has a significant amount of capacity for supporting the growing demand for fiber and will allow us to quickly and cost effectively deploy new fiber technology now and in the future. This uniquely positions CenturyLink to meet the needs of companies seeking highly reliable, low-latency network infrastructure designed to move massive amounts of data."

Corning has supplied its SMF-28 ULL fiber and SMF-28 Ultra fiber in a hybrid Corning SST-UltraRibbon cable for the deployments. The SMF-28 ULL’s silica core design enables the lowest loss terrestrial-grade optical fiber available, Corning and CenturyLink assert; the fiber enables improved optical signal-to-noise ratio (OSNR), which can extend optical reach at very high data rates, the companies say.
