Fiber Expansion Updates
Provider competition is the primary driver of fiber expansion in Gaithersburg, with Verizon Fios and Xfinity racing to connect new neighborhoods.

Fiber Internet Technology in Gaithersburg
Fiber-to-the-home (FTTH) internet in Gaithersburg uses glass or plastic optical fibers to transmit data using pulses of light. This technology delivers significant performance advantages over copper-based cable and DSL connections available in the Gaithersburg market.
Symmetrical speeds are a hallmark of fiber internet in Gaithersburg. Unlike cable internet where upload speeds are typically a fraction of download speeds, fiber plans from providers like Verizon Fios deliver equal upload and download performance. This is critical for Gaithersburg residents who work from home, participate in video conferences, or upload content to cloud services.
Latency as low as 1-5 milliseconds makes fiber in Gaithersburg ideal for online gaming, real-time video streaming, and VoIP calls.

How to Choose Fiber in Gaithersburg
Choosing fiber in Gaithersburg depends on your location and usage patterns.

Speed considerations: A 300 Mbps fiber plan handles 5-8 devices comfortably, including 4K streaming on multiple TVs.
