Definition: Optical Line Terminal or optical line termination is a device that basically acts as a part of a passive optical network (PON). It is present in the central office of the network and manages the transmission and reception of information across the overall network. Optical line terminal. A GEPON system usually consists of an OLT (Optical Line Terminal) at the service provider's central office and multiple ONU (Optical Network Units) or ONT (Optical Network Terminals) close to the end user as optical splitters. In addition, the transmission between OLT and ONU/ONT adopts an optical. An Optical Line Terminal (OLT) is a fundamental element within optical communication networks, serving as a hub that facilitates the transmission and reception of data, voice, and video services to and from subscribers' locations. It acts as the central point for controlling and managing network. In optical fiber technology, one of the most widely used devices is an optical line terminal, also called OLT. It can transmit and receive data at several hundreds of kilometers without loss. The OLT is responsible for converting incoming optical signals into electrical signals, which are.
