What is the function of an Optical Network Terminal (ONT)?

The function of an Optical Network Terminal (ONT) is to convert fiber optic signals for home use. An ONT serves as the interface between the fiber optic network provided by the service provider and the customer’s local area network. It takes the optical signals transmitted over the fiber cables and converts them into electrical signals that can be used by standard networking equipment, such as routers and computers. This conversion is crucial because it enables users to access internet services using traditional networking technologies over their home or business networks.

Understanding the operation of an ONT is vital, as it plays a key role in fiber-to-the-home (FTTH) deployments. It allows for high-speed internet access, supports multiple devices, and ensures efficient communication between the provider's network and the subscriber's equipment.
