Abstract

Optical glass fibers can exhibit a transition in slope of their static fatigue behavior ('knee' phenomenon). This effect was previously supposed to reduce fiber lifetime. The 'knee' phenomenon as well as the phenomenon of abrupt increase of the flaw size ('pop-in') are re- examined in this paper. It is shown that under normal proof-test conditions these two effects have no tangible impact on the fiber service life estimations.
