Fiber Internet

What is GPON and how does fiber internet reach your home?

June 28, 2025 1 min read

GPON (Gigabit Passive Optical Network) is the technology that brings fiber internet from your ISP to your home. Unlike traditional copper-based DSL or cable, GPON uses glass fiber optic cables to transmit data as pulses of light, enabling much faster speeds and lower latency.

How It Works

A single fiber from your ISP connects to a GPON modem (also called an ONT – Optical Network Terminal) in your home. This modem converts the optical signal into electrical signals that your devices can use.

Why GPON

GPON supports symmetrical speeds up to 2.5 Gbps downstream and 1.25 Gbps upstream, far exceeding traditional broadband. It’s also future-proof and highly reliable.
