In this paper, phase difference measurement caused by acoustical wave disturbance examined by using straight optical fiber cable as a measurand. A single mode optical fiber and underwater acoustical wave transducer was used in the experiment. The output result of the optical fiber cable is connected to a photon counter to performing the Poisson distribution.
