Paper Abstract

Proof testing is the principal technique for revealing the largest fiber flaws that reduce fiber strength below some definite level. At the same time the proof test does not guarantee long-term (25—50 yr) reliability of optical fibers due to the growth of surface defects during proof stress unloading. In the present paper we analyze the possibility of reducing unloading effects by means of shortening the unloading time or proof testing under inert conditions. We have also estimated the reliability of hermetically coated proof-tested optical fibers and obtained simple relations that take into consideration the proof test and service conditions when evaluating the fiber reliability.
