Light Source Communications (LSC) is continuing its expansion into key U.S. markets with a new dark fiber metro ring serving the Indianapolis, Indiana, area.

The 240-mile network will feature five rings encompassing about 20 municipalities with direct access to several data centers, allowing hyperscalers, neoclouds, and enterprises to power GPU-dense workloads and compete at global scale.

Demand for the project is being driven by tremendous growth in Artificial Intelligence (AI) and High-Performance Computing (HPC). LSC has multiple hyperscale tenants to anchor the route, which is being built entirely underground and is expected to be complete by the third quarter of 2027.

“As hyperscalers expand, neocloud platforms scale high-performance environments, and AI applications generate unprecedented data demand, the need for low-latency, high-capacity, and diverse fiber infrastructure continues to accelerate,” said Debra Freitas, CEO of LSC. “This new route strengthens regional connectivity, enhances network resilience, and provides the scalable foundation customers need to support rapidly evolving AI and cloud deployments.”

Indianapolis is one of several strategic markets where LSC is actively boosting connectivity for hyperscalers and enterprise customers alike. Construction is currently underway on dark fiber networks in Las Vegas, Phoenix, and Tulsa, Oklahoma. Additionally, in June, LSC completed construction of a 35-mile ring in Kansas City, Missouri. In Las Vegas, the company is building a critical 60-mile route. In Phoenix, LSC is developing a 335+ mile dark fiber metro ring, which is seeing tremendous demand. In Tulsa, LSC is adding 80 miles of new fiber to its existing 50-mile network. In addition to all of the networks being underground, all are anchored by a hyperscale tenant.
