The invention discloses an optical cable. The optical cable comprises an optical unit, an organic solvent resistant layer, an outer cladding layer, a micropore layer and a sealing layer. The optical unit, the organic solvent resistant layer, the outer cladding layer, the micropore layer and the sealing layer are successively arranged from inside to outside. A cavity is arranged in the outer cladding layer. Micropores are arranged in the micropore layer. The cavity is connected with the micropores through a capillary, and the micropores are mutually connected through microtubes. A chemical liquid having an irritant or expelling effect on rodents is arranged in the cavity. According to the invention, the chemical liquid having the irritant or expelling effect on rodents is arranged in the cavity, and the liquid in the cavity is absorbed into each micropore of the micropore layer by means of a capillary effect, so that the chemical liquid is enabled to expel the rodents; in addition, the volatilization of the liquid in the micropores is reduced as far as possible, the action time of the chemical liquid in the optical cable is substantially prolonged, the ratproof effect is obvious, and the cost is low.
