Zusammenfassung:The invention relates to the technical field of optical fiber links, and discloses an optical link cross-comparison and fault accurate positioning method and system, and the method comprises the steps: collecting the initial operation data, environment data and optical fiber feature data of an optical link through a sensor, building a comprehensive data set, analyzing the initial operation data of the optical link through employing an anomaly detection algorithm, marking abnormal data, and carrying out the cross-comparison of the optical link and the fault accurate positioning of the optical link. Removing the abnormal data and performing interpolation filling to obtain first operation data, training by using the first operation data of the optical link, the environment data and the optical fiber feature data to obtain an optical link comparison model, and collecting real-time operation data, real-time environment data and real-time optical fiber feature data of the optical link; the method comprises the foll
