The article proposes a method for non-destructive testing of optical fiber strength based on estimates of the energy of nonlinear acoustic emission and the tested optical fiber as an acoustic sensor with phase modulation of the optical carrier. Models of the processes on which the method is based are presented. The results of experimental studies are presented. The data obtained from the results of testing the fiber samples using the proposed method were compared with the results of the same samples' measurements by the known 2-point method. The error in relative estimates of the strength of the tested fiber samples did not exceed 3.0%. This allows us to speak about the correctness of the models used and the potential possibility of using the proposed method for non-destructive testing of the strength of optical fibers, as well as the prospects for the development of the application of the considered approach for measuring optical fibers strength in cable.
