Fiber Internet Technology in Decatur

Fiber optic internet in Decatur works by sending data as light pulses through thin glass or plastic strands. This fundamental technology difference gives fiber internet clear performance advantages over the cable and DSL alternatives available in Decatur.

Symmetrical speeds are a hallmark of fiber internet in Decatur. Unlike cable internet where upload speeds are typically a fraction of download speeds, fiber plans from providers like Xfinity deliver equal upload and download performance.

Latency as low as 1-5 milliseconds makes fiber in Decatur ideal for online gaming, real-time video streaming, and VoIP calls. Cable internet typically delivers 15-30ms latency, while DSL can reach 25-50ms. For Decatur households with multiple simultaneous users, fiber's low latency means smoother performance across all devices.

Future-proof infrastructure means Decatur's fiber networks can be upgraded to support speeds of 10 Gbps and beyond without replacing the physical cables. As bandwidth demands increase with 4K/8K streaming, virtual reality, and smart home devices, fiber subscribers in Decatur are positioned for decades of reliable, high-speed service.
