The invention discloses a novel termite-proof optical cable, comprising an anti-termite layer. The anti-termite layer is disposed outside or inside the sheath at the outermost layer of the optical cable, and the material of the anti-termite layer is polyethylene terephthalate. The invention adopts the anti-termite layer of polyethylene terephthalate material in the optical cable to achieve the anti-termite effect of the optical cable, and the structure (warping tapes, extrusion layers and the like) formed by the polyethylene terephthalate material is characterized by high rigidity, high hardness, and high smoothness of the surface, so that the termite does not bite, thereby achieving the purpose of preventing the termite.
