Novel anti-rat-bite anti-bending optical cable and preparation process thereof

The invention discloses a novel anti-rat-bite anti-bending optical cable and a preparation technology, the novel anti-rat-bite anti-bending optical cable comprises a cable core, an optical transmission unit, anti-bending reinforcing layers and an outer sheath, the cable core comprises the optical transmission unit and a central reinforcing core, each anti-bending reinforcing layer is provided with a plurality of leakage detection modules with positioning capability and an external reinforcing core, and the optical transmission unit is connected with the outer sheath. The outer reinforcement core is secured by a plurality of shroud rings. The external reinforcing core and the hoop ring are arranged in the anti-bending reinforcing layer, and a '1 + 1-7' structure is formed between the anti-bending reinforcing layer and the internal reinforcing core of the cable core, so that a stable supporting structure can be kept between components in the optical cable and the outer sheath; the flexible filler in the cable c
