Rat-proof optical cable

The invention belongs to the field of cables, and particularly relates to a rat-proof optical cable which is provided with a cable core, an inner protective layer, a rat-proof layer and an outer protective layer, the inner protective layer is extruded outside the cable core, the rat-proof layer is located outside the inner protective layer, and the outer protective layer is extruded outside the rat-proof layer. Each transmission unit is composed of a first nesting layer and at least one second nesting layer, the outermost second nesting layer is nested with the first nesting layer, all the second nesting layers are nested layer by layer, a first containing cavity is formed between the first nesting layer and one second nesting layer, a second containing cavity is formed between every two adjacent second nesting layers, and the first nesting layer and the second nesting layer are nested layer by layer. Optical communication components are arranged in the first accommodating cavity and the second accommodating
