The utility model belongs to the technical field of communication optical cables, and discloses a novel optical cable with a rat bite prevention effect, according to the utility model, through the arrangement of a second rat repelling layer and a flexible layer structure, when an inner protective layer is pre-buried in soil for use, the
toughness of the optical cable can be effectively increased by utilizing nylon materials on an outer protective layer, and the service life of the optical cable is prolonged. Meanwhile, by means of the thorn structure on the outer layer of the protective layer, the mechanical pricking feeling is generated when the
oral cavity of the mouse or the
rodent makes contact with the mouse or the
rodent, by means of the arrangement of the microcapsules of the first mouse repelling layer, after the mouse or the
rodent occludes the second mouse repelling layer,
menthol and
capsaicin are released by means of the microcapsules, and therefore the effect of repelling the mouse or the rodent with the
capsaicin is achieved. By means of the arrangement of the first rat repelling layer and the second rat repelling layer, double sensory attacks can be formed on rats from the
taste sense and the smell sense, by means of the arrangement of the second rat repelling layer, after the rats or rodents bite small glass fragments, the small glass fragments cause
stabbing pain on the oral cavities of the rats, and therefore the rats can be effectively stopped, and meanwhile by means of the arrangement of the flexible layer and the excellent flexibility of the flexible layer, the rats can be effectively repelled. The
plasticity during use is improved.
