What is an ONT?

Updated on 19 Mar, 2025

An Optical Network Terminal (ONT), known as the 'fibre box', is the superstar that brings super-fast internet into your home. Here's how it works:

How Does the ONT Work?

  1. Receiving Light Signals: The ONT catches the speedy light signals zipping through the fibre-optic cables that deliver the internet to your home.
  2. Converting Signals: It transforms these light signals into electrical signals.
  3. Distributing Internet Access: These electrical signals are then sent to your router, which shares the internet connection with all your devices.

In simple terms, the ONT is the bridge between the ultra-fast fibre-optic internet coming into your home and the devices you use to access the internet
