Rat-proof optical cable and rat-proof optical cable forming method

A ratproof optical cable disclosed by the present invention comprises nylon layers, outer sheath layers, a steel belt layer and an optical fiber unit, the outer side of at least one nylon layer is sleeved with at least one outer sheath layer, the steel belt layer is located at the inner side of the nylon layer, and the optical fiber unit is located at the inner side of the steel belt layer. The nylon layer is arranged on the inner side of the outer sheath layer, so that the forming effect is ensured, the thickness of the nylon layer can be increased under the same sectional area, and the anti-biting strength of the nylon layer can be further improved. And after a small amount of bite, due to the fact that the whole cover is still in place, good preliminary physical protection can still be achieved. And for the missing part caused by biting, due to the existence of the nylon layer, the physical protection effect is continuously achieved. In conclusion, the rat-proof optical cable can effectively solve the prob
