NOVELTY - The invention claims a cable side pressure sensor based on hollow optical fibre anti-resonance, comprising a hollow optical fibre, a single-mode optical fibre and a graphene; the single-mode optical fibre is two; the respectively ends of the hollow core optical fibre are welded to form a sensor probe structure; the graphene is coated on the periphery of the hollow optical fibre; the sensor probe covered by graphene is attached to the measuring point of the side pressure of the cable. The cable side pressure sensor based on hollow optical fibre anti-resonance of the invention, using light to generate anti-resonance reflection mechanism in the optical fibre when passing through the hollow optical fibre, so as to form FP resonant oscillation in the transverse direction of the optical fibre; when the graphene coated with the hollow core optical fiber is extruded, the optical reflectivity of the optical fiber surface will be weakened, so as to affect the intensity of the transverse FP resonance; the position of the resonant wavelength can detect the change of the light intensity, by monitoring the light intensity change of the output end; So the size of the force pressed by the side of the cable can be obtained.
