How Fast Does Fiber Internet Work?

Published in Internet Speed 2 mins read

Fiber internet, also known as fiber optic internet, offers incredibly fast speeds. In some areas, it can reach up to 10 Gigabits per second (Gbps). This impressive speed is possible because the technology uses fiber-optic cables that transmit data at approximately 70% the speed of light.

However, the actual speed you experience depends on several factors beyond the fiber connection itself. These include:

  • Your internet plan: Your chosen plan dictates your maximum download and upload speeds.
  • Network congestion: High traffic on your internet service provider's (ISP) network can slow things down.
  • Your home network: Wi-Fi performance, the age and capacity of your router, and the number of connected devices all impact speeds. Using a wired Ethernet connection directly to your modem bypasses Wi-Fi limitations, providing the fastest speeds possible. (Referencing Reddit comments discussing speed tests and wired vs. wireless connections).
  • VPN use: Certain VPNs can significantly impact speeds, as seen in the Reddit example showing slower speeds with a work VPN compared to NordVPN. (Referencing the Google Fiber Reddit post).

While fiber itself transmits data at an extremely fast rate, the overall speed you experience is a result of the combined effect of these contributing factors. It's important to remember that the advertised speed is a theoretical maximum.
