Abstract
A method and apparatus for detecting Passive Optical Network (PON) failures, and a PON system are provided to obtain the monitoring information of a peer device before a PON system failure occurs. The method includes: obtaining monitoring information of an Optical Line Terminal (OLT) and an Optical Network Unit (ONU); and determining a failure of a passive ONU according to the obtained monitoring information of the OLT and the ONU. The monitoring information of the peer device is obtained before a PON system failure occurs. Thus the failure is discovered in time, quick troubleshooting is ensured, and the costs of system maintenance are reduced.
