The invention discloses a predication method for electric power optical fiber communication optical power, relates to the technical field of optical fiber communication predication, and solves the problems that analysis and predication of a circuit state tendency cannot be achieved in the prior art and accordingly impending faults and the like cannot be avoided. According to the method, an improved particle swarm optimization algorithm is provided to optimize parameters in a predication model, so as to achieve a mixed predication based electric power optical fiber communication optical power predication method, accurately predicate a future state tendency of a circuit, predicate future possible faults of the circuit, make a maintenance strategy in advance, avoid fault generation and satisfy an optical fiber communication requirement for intermittent transmission. According to the predication method for the electric power optical fiber communication optical power, the parameters of the SVM model are optimized through the improved particle swarm optimization algorithm, the model not only has a quick operation convergence rate, but also has good predication accuracy and stability, a mixed predication model is adopted, respective advantages of every single predication model are effectively composited, mutual disadvantages are remedied, and improvement of the performance of the integral predication model is facilitated.
