OPTICAL CHANNEL IDENTIFICATION METHOD AND APPARATUS AND OPTICAL COMMUNICATION MONITORING DEVICE AND STORAGE MEDIUM

摘要

The present application provides an optical channel identification method and apparatus and optical communication monitoring device and storage medium, said method comprising: performing convolution processing on a convolution pre-processing signal and a spectral signal of a monitoring point to obtain a convolution spectrum, the convolution pre-processing signal being a pulse signal having a symmetrical waveform and obtained via first-order differentiation, the time-domain width of the pulse signal matching the scan time of the optical channel; performing second-order differentiation on the convolution spectrum to obtain a second-order differential resu using the sign of the second-order differential result to determine the frequency position of the peak and valley and achieve optical channel recognition.
