Definition: A passive optical network (PON) is a point-to-multipoint, fiber to the premises network architecture in which unpowered optical splitters are used to enable a single optical fiber to serve multiple premises, typically 32-128. A PON consists of an Optical Line Termination (OLT) at the service provider's central office and a number of Optical Network Units (ONUs) near end users.
A PON configuration reduces the amount of fiber and central office equipment required compared with point to point architectures.
Downstream signals are broadcast to each premises sharing a fiber.
Encryption is used to prevent eavesdropping.
Upstream signals are combined using a multiple access protocol, invariably time division multiple access (TDMA). The OLTs 'range' the ONUs in order to provide time slot assignments for upstream communication.
