The foregoing description is only an overview of the technical solutions of the present invention, and in order to make the technical means of the present invention more clearly understood, the present invention may be implemented according to the content of the description, and in order to make the above and other objects, features, and advantages of the present invention more obvious and understandable, the following preferred embodiments are described in detail with reference to the accompanying drawings.

Drawings

Fig. 1 is a schematic structural view of a flat rat-proof and termite-proof drop cable in the embodiment of the present invention.

Description of the labeling: 1. an optical fiber ribbon; 2. an inner sheath; 21. a side edge; 22. a stripping groove; 23. a limiting groove; 3. an outer sheath; 4. an end reinforcement; 5. a side reinforcement; 6. a water blocking tape.

Detailed Description

The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.

As shown in fig. 1, for the embodiment of the utility model provides a flat protection against rodents ant optical drop cable, the cross-section of this optical cable is the platykurtic, this optical cable includes optical fiber ribbon 1, inner sheath 2 and oversheath 3, optical fiber ribbon 1 is located in inner sheath 2, inner sheath 2 is located in oversheath 3, inner sheath 2 includes the both sides limit 21 that extends along optical fiber ribbon 1 length direction and the two arc connection faces of connecting both sides limit 21, the both sides limit 21 of inner sheath 2 is equipped with stripping off groove 22, be equipped with both ends reinforcement 4 in the inner sheath 2, the both ends of optical fiber ribbon 1 are located respectively to both ends reinforcement 4, be equipped with both sides limit reinforcement 5 between inner sheath 2 and the oversheath 3, side reinforcement 5 is located stripping off groove 22 and is covered stripping off groove 22. Since the strength of the optical cable is low at the stripping groove 22, the side strength member 5 serves to reinforce the stripping groove 22 and can effectively protect the stripping groove 22.
