ABSTRACT:
A method for detecting a failure network terminal in a Passive Optical Network includes: changing timeslots assigned to potential failure network terminals one by one; and determining the failure network terminal according to uplink data frames sent by the potential failure network terminals whose timeslots are changed. Embodiments of the present invention also disclose an apparatus and system for detecting a failure network terminal. The solution of the present invention may detect which Optical Network Unit/Terminal (ONU/ONT) fails and perform the corresponding processing in accordance with embodiments of the present invention, which recovers the system health and improves the network security, stability and self-healing ability.
