Abstract

One-third of the proof-test stress has been commonly quoted as the maximum allowable stress to ensure longevity of fibers. However, the basis of the rule are not appropriate for some installation practices and modern fibers. The Weibull parameter m for low-stress breaks was measured using a proof tester. The fatigue constant n was replaced with the parameter obtained from an abraded fiber. Using the new parameters and appropriate failure probabilities, engineering guidelines were derived for three representative lengths: 1000 km (long-haul cable), 1 m (fiber in a splice closure), and 1 cm (bent section of a pigtail fiber).
