Abstract

Temperature and vibration robustness of a reflecting all-fiber current sensor (AFCS) using a common single-mode fiber (SMF) are analyzed theoretically and experimentally. The effect of the birefringence condition of the sensing fiber on the temperature and vibration sensitivity of the AFCS is shown via theoretical models. The temperature and vibration sensitivity of the AFCS using an orthoconjugate retroreflector are almost entirely independent of the birefringence condition of the fiber. Thus, this configuration is preferable for a reflecting AFCS using an SMF. The experimentally observed temperature and vibration sensitivity of AFCSs using different fibers and configurations support this conclusion.
