SYSTEM AND METHOD FOR PERFORMANCE MONITORING IN A PASSIVE OPTICAL NETWORK

摘要

Networks and networks for performance monitoring (PM) in a passive optical network, which contain at least one optical line terminator (OLT) and at least one optical network terminal (ONT), provide increased PM flexibility over traditional ONT management and control interface functionality. These networks and networks include setting a PM initialization time at the ONT, maintaining a base PM time at the ONT, zeroing an interval end time counter at the ONT and collecting a first set of PM data in PM bins for a specified PM time interval. The interval end time counter can sequentially increment after completing collection the first set of PM data. Once collection of the first set of PM data is complete and the interval end time counter has been incremented, these networks and networks can collect more sets of PM data in other PM bins for the PM time interval.
