[0033] The present invention improves the original OPM mode and adopts the photoelectric combined monitoring mode. At the optical layer, the OPM function is still used to monitor optical power, wavelength, number of wavelengths, OSNR and other parameters to realize the monitoring and fault location of various optical devices and optical powers, while at the electrical layer, because the OTN adopts a unified G .709 encapsulation format, so it can monitor the bit error rate and routing information of each channel by monitoring the BIP and TTI bytes of the OTU and ODU layers. In order to reduce the cost of electrical layer monitoring, the present invention adopts the method of electrical layer non-intrusive polling monitoring, which is the essence of the present invention. The following describes the embodiments of the present invention in detail with reference to the drawings.
