Abstract
The invention relates to a temperature stress sensing optical cable which comprises field operation rubber. A strengthening core, a loose optical fiber and a tightly packaged optical fiber are horizontally arranged in the field operation rubber in a parallel mode. The strengthening core is arranged in the center of the field operation rubber, and the loose optical fiber and the tightly packaged optical fiber are arranged on the left side and the right side of the strengthening core. Due to the fact that a temperature sensing optical cable and a stress sensing optical cable are arranged in the same optical cable at the same time, the wiring frequency is reduced, and the detection cost is saved.
