Source abstract
A new method for reliability assurance of long length optical glass fibers is presented. This method is based on a simple equation by fracture-mechanics theory and provides failure probability prediction for fibers after proof testing. The prediction is made by using dynamic fatigue data obtained by simple tensile tests and failure number during proof testing. The experimental results are found to be in good agreement with those predicted by the theory, and it is verified that the method is useful to make reliability assurance of long optical fibers for long- term use.
