FATIGUE TESTING OF SILICA OPTICAL FIBRES

Manufacturing technologies of silica optical fibers are reviewed and the role of different external coatings underlined. Mechanical properties of optical fibers have been investigated and fatigue testing procedures were described. Different commercial silica optical fibers were tested. Dynamic fatigue testing using two point bending bench at four different stress rates were carried out. Fiber strength was determined using Weibull statistical treatment and
