ONU autodiscovery is the precondition for the normal operation of an EPON system. When an EPON system is running, ONU autodiscovery makes it work that a new ONU or malfunction ONU can be registered without any disturbing to the normal ONUs in the system. This results in good scalability and convenient operation maintenance of PON systems. In this paper, we analyze the basic requirements of ONU autodiscovery, describe the whole process of autodiscovery in details, and compare different schemes for register collision avoidance.
