Light Source Communications, a leading provider of secure, scalable, reliable connectivity on state-of-the-art dark fiber networks, announces the commencement of a major dark fiber route in the Phoenix, Ariz., metro area, following its deal with a major global hyperscaler as the anchor tenant. Once complete, this project will encompass nine cities, universities and several data centers in the metro area, delivering an exceptionally high fiber count and conduit system in one of the largest, fastest growing markets in the country.

This 140-mile, three-ring route will serve as a critical link for the Phoenix metro area, home to over 70 planned and existing data centers. Additionally, the route circles Arizona State University at Tempe and the University of Arizona. Engineering is well underway, with construction slated to begin in the third quarter of this year and expected to conclude by the end of 2025. The entire route will be underground, resulting in the greatest reliability and network security. As a carrier neutral, customer agnostic provider, Light Source aims to leverage this route to deliver enhanced connectivity solutions throughout this key metro area.

“This route is vital to meeting the growing demand for connectivity in the area. Phoenix embraces the growth of data centers and connectivity, and it is quickly becoming a premier destination for hyperscalers,” said Debra Freitas, CEO of Light Source Communications. “Artificial Intelligence, Machine Learning, Internet of Things and other emerging technologies require connections with high levels of capacity and reliability. This route will not only help to meet hyperscalers’ needs but also provide secure, scalable connectivity for enterprise customers in the region.”
