| description | The invention discloses a submarine cable health detection method based on forward stimulated Brillouin scattering under temperature-insensitive ocean current scouring, and the method comprises the steps: measuring the transverse pressure generated by seawater scouring on the surface of an optical fiber body wrapping a submarine cable, and judging the strength of the ocean current scouring effect on the submarine cable; comprising the following steps: step 1, laying an optical fiber on a submarine cable; 2, measuring the pressure of the ocean current scouring effect, and collecting the forward Brillouin frequency shift change of the optical fiber caused by the transverse pressure; and 3, processing the relation between the forward Brillouin frequency shift change and the pressure to obtain the transverse pressure on the surface of the optical fiber, namely the pressure caused by scouring the submarine cable by the ocean current. By using the frequency shift information of the two FBS scattering peaks, an ocea |
