Data synchronous transmission optimization method and system based on analog optical fiber communication

The invention belongs to the technical field of communication optimization, and particularly relates to a data synchronous transmission optimization method and system based on analog optical fiber communication. According to the method, after redundant data is generated in the communication equipment, a temporary transient period is constructed so as to judge whether the redundant data is instantaneous data or not, mistaken construction of a monitoring period is avoided, and after the monitoring period is constructed, trend analysis and prediction analysis are performed on to-be-evaluated parameters in the monitoring period, so that the accuracy of the monitoring period is improved. And the trend analysis result can be further verified, the monitoring period is adjusted in good time, the accuracy of the finally obtained estimated redundancy is ensured, then the estimated redundancy is taken as the basis, the evaluation model and the self-adaptive optimization model are combined to adjust the output time seque
