A passive optical network (PON) is a telecommunications network that uses only unpowered devices to carry signals, as opposed to electronic equipment. In practice, PONs are typically used for the between (ISP) and their customers. In this use, a PON has a topology in which an ISP uses a single device to serve many end-user sites using a system suc.
