Light Source Communications (LSC) launched a new 240-mile dark fiber network in the Indianapolis metro area, targeting hyperscalers, neocloud operators, and enterprises deploying GPU-dense AI and high-performance computing workloads. The carrier-neutral provider said the route will feature five high-capacity fiber rings spanning roughly 20 municipalities, with direct connections to multiple regional data centers. LSC has already secured several global hyperscalers as anchor tenants ahead of full build-out.
The Indianapolis network will be constructed entirely underground and is scheduled for completion by the third quarter of 2027. LSC said the design emphasizes low latency, high fiber counts, and route diversity to support AI and cloud deployments that require scalable bandwidth and resilient metro connectivity. The company positioned the build as part of a broader shift toward high-capacity regional infrastructure supporting financial institutions, government facilities, and research and education networks across the Midwest.
Indianapolis joins a growing list of LSC expansion markets. Construction is underway on new dark fiber routes in Las Vegas (60 miles / 97 km), Phoenix (335+ miles / 539+ km), and Tulsa (adding 80 miles / 129 km to an existing 50-mile / 80 km network). The company completed a 35-mile (56 km) ring in Kansas City, Missouri, in June. All networks are built underground and anchored by hyperscale tenants.
• 240-mile (386 km) dark fiber metro network in Indianapolis
• Five fiber rings across ~20 municipalities
• Multiple hyperscaler anchor tenants secured
• Completion targeted for Q3 2027
• Fully underground construction model
• Additional builds: Las Vegas (60 miles / 97 km), Phoenix (335+ miles / 539+ km), Tulsa (80-mile / 129 km expansion), Kansas City (35 miles / 56 km completed)
“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.
🌐 Analysis: LSC’s Indianapolis build aligns with a broader Midwest data center expansion trend, as secondary markets attract AI workloads due to power availability and lower land costs compared to Tier 1 hubs. Regional fiber densification has accelerated in markets such as Phoenix and Kansas City, where hyperscalers seek diverse metro rings to interconnect GPU clusters and on-ramps to long-haul routes. By securing anchor hyperscalers before completion, LSC reduces commercial risk and signals sustained demand for dark fiber as AI clusters scale beyond traditional core metros.
