ONT vs Router vs Modem: What is the Difference?
When setting up fiber internet, you will hear terms like ONT, router, modem, and gateway. This guide breaks down what each device does and which ones you actually need.
What is an ONT?
An ONT (Optical Network Terminal) converts optical signals from fiber optic cable into Ethernet signals. It is essential for fiber-to-the-home (FTTH) internet.
Langzhi Technology offers GPON ONT and EPON ONU devices.
What is a Modem?
A modem is used for DSL or cable internet over copper lines. Fiber internet uses an ONT, not a traditional modem.
What is a Router?
A router distributes internet to multiple devices and provides WiFi. It must connect to an ONT for fiber internet.
Key Differences
