When you stream a 4K video, join a remote meeting, or play an online game on a gigabit fiber connection, an OLT silently coordinates all that data from your internet provider to your home. In short: The OLT (Optical Line Terminal) is the central control unit of a Passive Optical. A Gigabit Ethernet Passive Optical Network (GEPON) system is generally composed of an optical line terminal (OLT) at the service provider's central office and a number of optical network units (ONUs) or optical network terminals (ONTs) near end users, as well as the optical splitter. In addition. 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. To date, most FTTH deployments in planning and deployment have used PON to save on fiber costs. PON has attracted much attention in recent years due to its low cost and high performance.
