Abstract:

With the further extending of the transmission distance in long-haul fiber optic hydrophone system, the effects of various optical nonlinear effects are getting dominant. Optical nonlinear effects has been the bottleneck that limits the performance of the system. This paper reviews the study on the optical nonlinear effects in long-haul fiber optic hydrophone system. The main nonlinear effects in long-haul fiber optic hydrophone system are analyzed. The principles of Stimulated Brillouin scattering and modulation instability are analyzed in detail. The effects of SBS and MI on the system’s phase noise are presented. Finally, the paper introduces the methods to suppress the nonlinear effects.
