Abstract (EN): In this work, a Fabry-Perot optical fiber sensor for the measurement of strain at extreme temperatures is proposed. The cavity is formed by splicing a short section of a silica tube between two sections of single mode fiber. The tube, with a cladding similar to 14 mu m thick and a hollow core, presents four small rods, of similar to 20 mu m in diameter each, positioned in in diametrically opposite positions. This design ensures higher mechanical stability of the tube. Strain measurements are performed over a wide range of temperatures, until 900 degrees C. Some of the annealing effects are addressed in this study.
