This paper aims to solve the problem of the fiber optic cable sensitivity measurement. A fiber optic cable sensitivity measurement method is proposed based on distributed acoustic sensor (DAS) system, and an experimental device is implemented. Five different optical cables are connected to the DAS system, and the acoustic pressure sensitivity of different optical cables at different frequencies is measured through the DAS system. The results show that the cable G654 has the maximum sensitivity of -148.84 dB(rad/μPa) at 120 Hz, GYTA53T has the maximum sensitivity of -160.68 dB(rad/μPa) at 140 Hz, and G657A2 has the maximum sensitivity of -166.07 dB(rad/μPa) at 160 Hz.
