What percentage of U.S. homes have access to fiber internet?

Based on FCC data, approximately 96% of U.S. ZIP codes have at least one fiber-to-the-home provider. Fiber availability varies significantly by state and between urban and rural areas.

Why is fiber internet better than cable?

Fiber offers symmetrical upload and download speeds (e.g., 1 Gbps both ways), lower latency, and higher reliability than cable. Fiber speeds don't degrade with distance or network congestion. Most fiber plans also cost less per Mbps than cable in competitive markets.
