# Best Fiber Internet Providers in Tempe, AZ (2026)

Tempe is the beating heart of the East Valley tech scene, home to Arizona State University -- the largest public university in the country -- along with a dense concentration of tech companies near Tempe Town Lake, the Marina Heights complex (home to State Farm's regional HQ), and the ASU Research Park. Neighborhoods like Maple-Ash, University Heights, and the rapidly developing areas south of Baseline Road are packed with students, startup founders, and remote workers who need fast, reliable internet.

Tempe benefits from fiber competition between CenturyLink/[Quantum Fiber](/providers/centurylink) and limited [Cox](/providers/cox) Fiber availability. Quantum Fiber has been the more aggressive builder in the residential market, expanding across Tempe's neighborhoods to bring true symmetrical fiber service to homes that previously had only cable as a high-speed option.

Bottom Line Tempe's status as a major university and tech hub makes fiber essential.

Fiber keeps pace with the Valley of the Sun's fastest-growing city.
