An OLT (Optical Line Terminal) is the core device in a Passive Optical Network (PON) — the interface between the core network and the subscriber's optical access network. It aggregates multiple ONUs/ONTs through optical splitters and handles data distribution, management, and synchronization. 0 solution uses two transformative technologies to support five typical network scenarios. In the earliest FTTH solution, ODN 1. OLT is typically located in the Central Office/Headend (CO/HE), but there are also solutions where OLT is remotely located – for example the mini OLTs used. 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. When you stream a 4K video, join a remote meeting, or play an online game on a gigabit fiber connection, an OLT.
