ترمینال خطی نوری
A typical PON consists of an optical line terminal (OLT) at the service provider's central office, a number of optical network units (ONUs) or optical network terminals (ONTs) close to the end-users, and the optical distribution network (ODN) between.
Since fiber infrastructure of the PON is based on passive point-to-multipoint architecture, the feeder subchapter which is from the OLT to the remote node is shared by all ONUs and hence the cost on a per-user basis can be kept low.
An OLT is connected with many ONUs via a remote node, which usually contains one or several optical power splitters.
In the downstream direction, all the packets from the OLT are broadcasted by the splitter and sent to each ONU.
multiplexed by the remote node in the time domain and sent to the OLT.
