What is the purpose of an optical network terminal (ONT)?

An optical network terminal (ONT) serves a crucial role in fiber optic communications by converting the signals transmitted over fiber optics into electrical signals that can be utilized by various devices in homes or businesses. This conversion is essential because while fiber optic cables are superb at transmitting light signals over long distances with minimal loss, the devices that typically use these signals—such as computers, routers, and modems—operate on electrical signals.

The ONT acts as an interface between the fiber optic network and the local network within a building. It takes the optical signals received from the fiber optic cable and converts them into standard electrical signals, allowing devices to communicate with the broader internet and vice versa. This function is fundamental to ensuring that users can access high-speed internet and other services provided through fiber optics.

Understanding this function highlights why the other options do not accurately describe the ONT’s purpose. Amplifying signals is a function associated with repeaters, installing cables pertains to the roles of technicians or installers, and powering systems does not specifically relate to the signal conversion role that is central to the ONT's function.
