An Optical Line Terminal (OLT) is the central endpoint hardware in a PON architecture. Positioned in the Service Provider's Central Office (CO), it acts as the interface between the core network (the Internet) and the end-users. In addition, the transmission between OLT and ONU/ONT adopts an optical. An optical line termination (OLT), also called an optical line terminal, is a device which serves as the service provider endpoint of a passive optical network. At present, it is mainly divided into Class B+and Class C+, and the optical power range on the ONU side is generally 1-2 dbm less than that on the OLT. In the age of fiber-to-the-home (FTTH) and ultra-broadband connectivity, the Optical Line Terminal - or OLT - is one of the most crucial devices powering our high-speed digital world. If you are building a Fiber-to-the-Home (FTTH) or Fiber-to-the-Business (FTTB) network, understanding the OLT is critical for ensuring high-speed, reliable.
