Full-medium self-bearing type anti-mouse introduce fiber

The invention relates to a full-medium self-bearing type anti-mouse introduce fiber. The fiber comprises an outer sheath and an optical communication unit and is characterized in that three non-metalanti-mouse reinforcement pieces with circular cross sections coat the interior of the outer sheath and are arranged around a cable center so a center cavity is formed; and the optical communication unit is laid in the center cavity. According to the invention, by placing the three non-metal anti-mouse reinforcement pieces with circular cross sections in the sheath of the fiber and placing the optical communication unit in the center cavity formed through enclosing of the three non-metal anti-mouse reinforcement pieces with circular cross sections, the non-metal anti-mouse reinforcement piecesare GFRP anti-mouse reinforcement pieces with firm and smooth surfaces, so the fiber has quite high mouse bit and bird peck resisting performance; the non-metal reinforcement pieces have strong tension resisting ability and st
