METHODS AND DEVICES FOR MEASURING PROPERTIES OF COATINGS ON OPTICAL FIBERS

摘要

A method for measuring a mechanical property of a coating on an optical fiber may include collecting Brillouin frequency shift data of the coating on the optical fiber, and determining the mechanical property of the coating by comparing the collected Brillouin frequency shift data with correlation data that may include a set of collected sample Brillouin frequency shift data and a set of collected sample mechanical property data of a plurality of sample materials. The sample materials may include a substantially identical sample composition including one or more curable polymers, be prepared with varying processing conditions, and have different mechanical property values. The coating on the optical fiber may include a material composition substantially identical to the sample materials composition. The set of collected sample Brillouin frequency shift data may be correlated with the set of collected sample mechanical property data to determine a quantitative relationship therebetween.
