Strain Measurement in Tight Buffer Cabled Optical Fiber

摘要

We have experimentally carried out a comparative study of strain in a tight buffer cable with that of a loose fiber using Brillouin Optical Time Domain Analysis (BOTDA). The Brillouin frequency shift was measured to be 300 MHz, which corresponds to the strain of 6000 μ-strain appearing on the fiber in tight buffer cable, with respect to the loose fiber.
