LSC to build 240-mile underground dark fiber network in Indianapolis

(UI) — Light Source Communications (LSC) plans to construct a 240-mile underground dark fiber network across the Indianapolis metropolitan area, expanding fiber infrastructure to serve data centers and enterprise customers in the growing Midwest market.

The project will include five high-capacity fiber rings spanning approximately 20 municipalities, with direct connectivity to multiple data centers throughout the region. The network is designed to support hyperscale and enterprise demand tied to artificial intelligence and high-performance computing workloads.

The Indianapolis route will be built entirely underground, a design approach LSC says is intended to enhance network security and reliability. Construction is expected to be completed by the third quarter of 2027.

LSC says it has secured multiple hyperscalers as anchor tenants for the new route, reflecting increased demand for low-latency, high-capacity fiber infrastructure in the region.

"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 has emerged as an expanding data center market in the Midwest, with investment activity increasing in recent years. The 240-mile buildout adds to LSC’s broader underground network expansion strategy, which includes projects currently under construction in Las Vegas, Phoenix and Tulsa. The company recently completed a 35-mile fiber ring in Kansas City.

LSC operates as a carrier-neutral provider and owns its underground networks.
