Abstract

Some manufacturing technologies of silica optical fibres are reviewed and the role of polymer external coatings underlined. Mechanical properties of some commercial optical fibres have been investigated and fatigue testing procedures were described. Experimental testing devices, results treatment and parameters comparison have been evidenced. Dynamic fatigue testing using two point bending bench at four different stress rates were carried out. Fibre strength was determined using Weibull statistical treatment, then the n-corrosion parameter was calculated on the basis of four different stress rates. Static fatigue testing were carried on winding sample fibre around alumina mandrel. Fibre time to failure was measured and the n-corrosion factor was calculated on the basis of four different stress rates controlled through the mandrel-sized calibrated diameter..
