1. A method, comprising:
obtaining data of a network device on an optical link, wherein the data comprises optical power;
determining a fault mode on the optical link based on one or more feature parameters indicating a change in relation to the data that is within a preset time window, wherein determining the fault mode on the optical link comprises matching the one or more feature parameters against a fault mode identification model to determine the fault mode; and
after determining the fault mode, comparing the fault mode with an actual fault mode corresponding to the one or more feature parameters, and based on the fault mode being inconsistent with the actual fault mode, adding the one or more feature parameters and the actual fault mode corresponding to the feature parameter to a training set.
