Light Source Communications is expanding its dark fiber network with a new 400-mile route connecting Amarillo, Texas, to Oklahoma City, Stillwater, and Tulsa, announced in a press release. The build is anchored by a hyperscale tenant and includes seven in-line amplifiers to maintain signal strength across the route.

The project represents LSC’s third new dark fiber build this year and is scheduled for completion in the first quarter of 2027. It runs concurrently with the company’s ongoing 500-mile St. Louis–Tulsa route, which will connect to LSC’s existing 130-mile metro ring in Tulsa.

LSC’s expansion also includes new fiber networks in Indianapolis, Las Vegas, Phoenix, and Tulsa, all designed to support hyperscale, machine learning, and high-performance computing applications. Each of these underground networks is built for high capacity, low latency, and network diversity to meet growing AI infrastructure demands.
