Abstract

A ratio of inert to ambient strength >= 1.5 is suggested for large flaws in optical fiber near the proof stress level. Also, a temperature dependent strength at low temperatures, similar to that observed in pristine fibers, was investigated. An increase in fracture toughness or changes to the crack tip geometry at low temperatures did not account for the increase in strength at low temperatures. Inert strength distributions were predicted from strength obtained under ambient conditions for as-manufactured fiber and fibers with handling damage.
