Phoenix

The LSC Phoenix metro network spans over 335 route miles and consists of 15 high-capacity fiber rings. Originally engineered as a 140-mile topology, rapid regional demand for AI infrastructure driven by hyperscale requirements prompted a massive expansion, including an additional 35+ route miles in the West Valley. This current 15-ring layout delivers comprehensive physical layer depth interconnecting nine distinct cities across the metropolitan area.

Phoenix’s growing data center ecosystem, featuring power inventory scaling from 804 MW to over 1,800 MW coupled with university research hubs and intense hyperscale activity creates an immediate, critical regional requirement for the low-latency, high-density physical fiber lines that LSC deploys.

LSC’s Phoenix network provides critical physical path access to over 70 planned and existing data centers across the Valley. The high-fiber-count route explicitly serves high-density data hubs in the Goodyear area and provides direct, carrier-neutral dark fiber connectivity into Edged’s newest ultra-efficient data center in Mesa, Arizona, located less than 25 miles from downtown Phoenix.

LSC ensures complete network diversity and resilience by constructing 100% of its 335+ mile Phoenix infrastructure entirely underground. This subterranean conduit design utilizes a high-fiber-count architecture to eliminate the environmental vulnerabilities, severe weather exposures, and physical disruption risks common with aerial paths, safeguarding real-time Machine Learning (ML) data flows for high-availability enterprise networks.

Multiple hyperscalers anchor the Light Source Communications Phoenix dark fiber infrastructure. Operating strictly as a carrier-neutral, customer-agnostic wholesale utility, this physical layer configuration allows neocloud platforms, cloud service providers (CSPs), and massive enterprise GPU clusters to lease private fiber pairs and scale their bandwidth capacity without artificial constraints.

LSC’s high-capacity Phoenix network is fully active and delivering dark fiber service across its core 15-ring metro framework. To accommodate the region’s explosive data inventory surge, which is scaling from 804 MW to over 1,800 MW, LSC maintains ongoing infrastructure expansions, allowing for immediate, customized fiber allocations and rapid underground deployments directly into high-growth zones like the Goodyear corridor and the Edged data center ecosystem in Mesa.
