Which statements about an ONT are CORRECT?

An ONT is a device used in fiber-optic communication networks. It serves as the interface between the fiber-optic line coming into the premises and the customer's equipment. The primary function of an ONT is to convert the optical signals transmitted over the fiber-optic line into electrical signals that can be understood by the customer's devices, typically using Ethernet technology. Additionally, an ONT typically requires external power to operate since it contains active components that need electrical power to function.

The statement "It is user-installed" is not necessarily correct. The installation of an ONT can be performed by the service provider or a professional technician, depending on the specific circumstances and service agreements. It may not be a device that the end-user installs independently.
