Description

technical field [0001] The invention relates to the technical field of optical fiber line state prediction, in particular to a method for optical fiber line state prediction based on an improved firefly algorithm to optimize Elman neural network. Background technique [0002] In order to meet the needs of efficient, fast and reliable transmission of information in power systems, optical fiber communication networks have been widely used as backbone networks. Therefore, once the optical fiber line fails, the communication interruption caused will bring huge economic losses to enterprises and users. Since faults on optical fiber lines are inevitable, it is of great significance to predict possible optical fiber faults based on the status of existing optical fiber lines, and to do maintenance and management in advance, thereby avoiding faults and ensuring normal communication. [0003] Optical power data can fully characterize the working state of optical fiber lines, and is a...
