Claim 14:
15. A system, comprising:
a network device on an optical link; and
an optical link fault identification apparatus, wherein the optical link fault identification apparatus is configured to:
receive data of the network device from the network device that comprises optical power,
determine 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 windows 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, compare 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, add the one or more feature parameters and the actual fault mode corresponding to the feature parameter to a training set.
