Optical fibre breaks collection procedure for break source analysis
This application note briefly introduces optical fiber break source analysis (BSA) and explains procedure for collecting fiber break ends and other relevant information for BSA.
When a certain tension is applied, optical fiber breaks at the lowest strength point. Proof testing is a common technique to ensure optical fiber has some minimum strength and eliminate flaws whose sizes are dependent on the stress applied during proof testing. In proof testing, predetermined load is applied on fiber by tensile loading. The fiber breaks at the weak points and the weak parts are eliminated from the fiber.
