Optical router bridging fault positioning method based on single fault model

The invention discloses an optical router bridging fault positioning method based on a single fault model, and the method comprises the following steps: initializing the specific attributes of each input port and each output port of an optical router, classifying micro-ring resonators in the optical router, and dividing the micro-ring resonators into inlet resonators and outlet resonators; grouping the inlet resonators according to the connected input ports, and inputting test signals corresponding to the inlet resonators at the input ports according to the inlet resonators; after a to-be-tested signal is input, acquiring a first signal detected by each output port of the optical router, comparing the first signal with a standard output signal of each output port of the optical router in a fault-free state, and if the first signal does not conform to the standard output signal of each output port, determining the micro-ring resonator with the bridging fault according to the difference of the output signals. 本
