Aiming at the problem of optical cable connector fault location,this paper proposes an OTDR curve analysis method based on Bayesian and least square method based on the traditional OTDR curve analysis method to study the remote location and discovery of optical cable connector faults..Firstly,this paper analyzes the advantages and disadvantages of traditional OTDR curve analysis methods,including wavelet analysis and least square method.Secondly,OTDR curve analysis method based on Bayesian and least squares is used to detect the fault point.Then,the fault point is accurately located based on GIS algorithm.Finally,the proposed algorithm is verified by experimental simulation.The experimental results show that the fault location information of the proposed algorithm is highly consistent with the actual fault location information.
