Optical passive network (PON) is a telecommunications technology that implements a one-point-to-multiple-point synchronization architecture. Passive Optical Networks (PON) is a telecommunications technology that implements a point-to-multi-point architecture that is used in U Tor fiber optic instruments. In these networks, a fiber optic can serve multiple endpoints using separators or splitters، which passively split the fiber bandwidth between endpoints without power. To enable a fiber optic to serve several end points like clients without having to arrange individual fibers between the hub and the client.

network optical turn composed of a terminal line optical (OLT) at the service provider's central (hub) and a number of units optic network (commitment) (ONUs) or terminals optic network (ONTs) near end users. A passive optical network reduces the amount of fiber and central service equipment needed compared to a point-to-point architecture. Optical passive network is a type of optical fiber access network.< < > in most cases downstream signals are broadcasting to all locations that share a common fiber. Encryption can prevent eavesdropping. upstream signals using Multiple Access Protocol usually multiple access Time section (TDMA) are combined.
