We demonstrate distributed acoustic sensor using broadband weak fiber Bragg grating array for large temperature tolerance in an phi-optical time domain reflectometry system with a balanced Michelson interferometer. The system was tested with large difference in local temperature, 18 degrees C and 50 degrees C, simultaneously, and achieves a relatively flat frequency response from 20 Hz to 1200 Hz.
