Abstract: The present invention provides a protection switching method for a passive optical network. The method includes receiving, by an optical network unit ONU through each of two uplink passive optical network PON interfaces, an optical network terminal management and control interface OMCI message delivered by an OLT, where the OMCI message includes: configuration information on a work side and configuration information on a protect side; and processing, by the ONU by using each of two independent OMCI MIBs of the ONU, the OMCI message received by each of the two uplink PON interfaces, updating each of the two independent OMCI MIBs according to the OMCI message, and independently responding to the OMCI message.

Abstract: The present disclosure disclose an optical line terminal, including: an acquiring unit, configured to acquire device information of an optical network terminal that registers and gets online; a determining unit, configured to match the device information of the optical network terminal with an interoperability mode configuration table preset on the optical line terminal, and determine whether an interoperability mode obtained by matching is the same as a current interoperability mode; an instructing unit, configured to instruct, if the interoperability mode obtained by matching is different from the current interoperability mode, the optical network terminal to be reset, reregister, and get online; and a configuring unit, configured to switch the current interoperability mode to the interoperability mode obtained by matching, and configure and manage the optical network terminal according to the interoperability mode obtained by matching.
