D commercial fiber) is presented and experimentally demonstrated. Benefiting from the difference of the temperature and strain sensitivity from different Brillouin peaks with different acoustic modes, our proposed sensing configuration can be used to distinguish ambient temperature and applied strain at the same time, which is an excellent candidate to address the problem of cross-sensitivity in the classical Brillouin system. In the experimental section, using a 21.8 km sensing length of communication optical fiber, a temperature accuracy of 1.13°C and a strain accuracy of 21.46  με同时得到。考虑到我们目前所取得的性能，所提出的创新和实验装置将在光纤传感器领域有一些潜在的应用。SN - 1687-9384 UR - https://doi.org/10.1155/2021/6610674 DO - 10.1155/ 2012.1 /6610674 JF - International Journal of Optics PB - Hindawi KW - ER -
