APON: ATM Passive Optical Network

ATM Passive Optical Network (APON), or ATM PON, is the initial PON specification defined by the FSAN (Full Service Access Network) group using ATM as their layer 2 signaling protocol. Use of the term APON led users to believe that only ATM services could be provided to end-users, so the FSAN decided to broaden the name to Broadband PON (BPON). BPON systems offer numerous broadband services including Ethernet access and video distribution.
