[0002] With the rapid development of 5G communication and IoT technologies, fiber optic networks are evolving towards higher density and miniaturization.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] A mini optical fiber cable, such as Figures 1-6 As shown, it includes optical fiber 2, which is provided in multiple sets. The multiple sets of optical cables are all covered by an inner layer 6. The inner layer 6 tightly wraps the multiple sets of optical fibers 2, making the optical fiber 2 have a small diameter and a miniature size.

[0026] The end of the tear-off structure furthest from the bend end 10 is fixed to the inner layer 6. The distance between the top of the protruding structure and the outermost layer of the outer sheath 7 is the shortest. Therefore, the area between the top of the protruding structure and the outer wall of the outer sheath 7 is the weakest. The tear-off structure is less prone to breakage than the outer sheath 7. When the optical cable is recovered, the outer sheath 7 is peeled off, and the two ends of the optical cable are rotated and installed on the outer structure. Then, the bend end 10 is pulled forcefully, and the tear-off structure is detached from the optical cable. At the same time, the tear-off structure pulls the outer sheath 7, causing the outer sheath 7 to tear open. The design of the protruding structure and tear-off structure in this optical cable not only enhances the mechanical strength of the optical cable, but also realizes the convenient peeling of the outer sheath 7, greatly simplifying the on-site construction operation.

[0027] Furthermore, the raised structure can be a spiral raised 8, and the tearing structure can be a spiral raised strip 9. The two are intertwined and spiraled, pulling the raised 8 so that the raised 8 detaches from the inner layer 6 and tears the outer sheath 7, causing the outer sheath 7 to peel off.

[0028] Specifically, to prevent the bent end 10 at the end of the protrusion 9 from sticking up and being accidentally pulled, a ring 12 is designed. The ring 12 has a certain elasticity and is sleeved on the outside of the optical cable to compress the bent end 10 and prevent the bent end 10 from being accidentally pulled.

[0029] Furthermore, the raised structure can be a straight raised section 13, and the tearing structure can be a straight raised strip 14. The tops of both raised section 13 and raised section 8 are conical, which creates a weak point in the outer sheath 7. When raised section 13 and raised strip 14 are used, pulling on raised strip 14 causes the position between the top of raised section 13 and the outer wall of the outer sheath 7 to break, allowing the outer sheath 7 to be peeled off from the inner layer 6.

[0030] Furthermore, the unique reinforcing core 1 and separator frame 5 structure effectively improves the tensile strength and compressive strength of the optical cable, while ensuring the relative position stability between multiple fiber groups 2.

[0031] Furthermore, the filling layer 4 fills the gap between the optical fiber 2 and the inner layer 6. The cavity 3 design in the filling layer 4 not only reduces the weight of the optical cable, but also provides additional buffer protection.

[0032] The working principle of the mini optical fiber 2 cable provided by this utility model is as follows:

[0033] By designing a protruding structure and a tearing structure in the inner layer 6 of the optical cable, the mechanical strength of the optical cable is enhanced. The tearing structure causes the weak points of the outer sheath 7 to be damaged and torn, so that the outer sheath 7 can be easily peeled off. A ring 12 is fitted on the outside of the outer sheath 7 to prevent the bent end 10 of the tearing structure from being accidentally pulled.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
