Optical link fault identification method, apparatus and system

An optical link fault identification apparatus, comprising:

• a non-transitory computer readable medium storing computer-executable instructions;
• and
• a processor, wherein the processor is configured to retrieve and execute the computer-executable instructions to cause the apparatus to perform the following operations:
• obtaining performance data from an optical network device connected to an optical link, wherein the performance data comprises receive optical power;
• extracting a feature parameter from the performance data used to determine a change of the performance data that is within a preset time window;
• and
• identifying a fault mode on the optical link based on the feature parameter, wherein identifying the fault mode on the optical link based on the feature parameter comprises:
• matching the feature parameter against a fault mode identification model to determine the fault mode, wherein the fault mode identification model is trained using historical data, wherein the historical data comprises a set of feature parameters and a set of fault modes, wherein each feature parameter in the set of feature parameters corresponds to a fault mode in the set of fault modes;
• and
• comparing the fault mode with an actual fault mode corresponding to the feature parameter, and in response to the identified fault mode being inconsistent with the actual fault mode, adding the feature parameter and the actual fault mode corresponding to the feature parameter to a training set of the fault mode identification model.
