It is to be understood that the drawings are not to scale as the actual practice of the invention, but are for illustrative purposes and are not drawn to scale.

Please refer to fig. 1, which is a schematic diagram of a novel optical cable according to an embodiment of the present invention. The utility model discloses a novel optical cable 100, it includes that optical cable main part 10 and symmetry set up many auxiliary reinforcement of optical cable main part 10 surface both sides. Wherein the plurality of auxiliary reinforcing members include two or more auxiliary reinforcing members. In some possible embodiments, the number of auxiliary strength members disposed on both sides of the outer surface of the cable main body 10 is the same or different. In some possible embodiments, the number of auxiliary strength members disposed on each side of the outer surface of the cable main body 10 is plural and arranged side by side or in a matrix, or only one auxiliary strength member is disposed on each side of the outer surface of the cable main body 10. The following description will be given taking as an example that only one auxiliary strength member is provided on each side of the outer surface of the optical cable main body 10. Specifically, novel fiber optic cable 100 includes secondary strength member 1 and secondary strength member 4.

Cable body 10 and

auxiliary strength members

1 and 4 are all circular in cross-section. The auxiliary reinforcing member 1 and the auxiliary reinforcing member 4 are made of a metal material or an aramid material. The axes of the optical cable main body 10, the auxiliary reinforcing member 1 and the auxiliary reinforcing member 4 are on the same straight line, and the diameters of the auxiliary reinforcing member 1 and the auxiliary reinforcing member 4 are smaller than that of the optical cable main body 10.

Auxiliary strength members

1 and 4 are detachably connected to cable main body 10 via tearable tear 11. The tear portion 11 is a thin film which is easily torn. When using the novel optical cable 100, by applying an external force to the

auxiliary strength members

1 and 4 in a direction away from the cable main body 10, the tear 11 is torn so that the

auxiliary strength members

1 and 4 are separated from the cable main body 10.

It can be understood that, when the novel optical cable 100 is installed by pulling, the novel optical cable 100 can be pulled by means of the auxiliary reinforcing member 1 and the auxiliary reinforcing member 4, so that the novel optical cable 100 has strong tensile resistance, thereby further protecting the optical cable main body 10, and being suitable for laying occasions requiring large tensile force. In addition, because the auxiliary reinforcing members 1 and the auxiliary reinforcing members 4 are symmetrically arranged on two sides of the optical cable main body 10, the novel optical cable 100 is in a balanced state when being installed as a stay wire, and the operation is convenient.

Further, the auxiliary reinforcement 1 and the auxiliary reinforcement 4 are provided with a first outer jacket 9. The cable body 10 includes a second outer jacket 3. The first outer jacket 9 is wrapped around the

auxiliary strength members

1 and 4, and the second outer jacket 3 is wrapped around the cable main body 10. The tear 11 is connected between the first outer jacket 9 and the second outer jacket 3 of the auxiliary reinforcement 1 and between the first outer jacket 9 and the second outer jacket 3 of the auxiliary reinforcement 4. In the present embodiment, the materials used for the first outer sheath 9 and the second outer sheath 3 are the same, and the materials used for the first outer sheath 9 and the second outer sheath 3 may be, but are not limited to, PE/LSZH/nylon, etc.

The structure of the cable body 10 includes optical fibers 8, a loose tube 6, a first strength member 5, a second strength member 7, a second outer jacket 3, and a color bar 2. Wherein, loose tube 6 parcel is outside optic fibre 8, and first reinforcement 5 is the hollow cylinder, and the cover is located outside loose tube 6. The second outer sheath 3 envelops the first reinforcement 5. The second outer sheath 3 is also embedded with a second reinforcing part 7 and a color bar 2, and the second reinforcing part 7 and the color bar 2 are symmetrically arranged. The axial centers of the two second reinforcing members 7 and the axial center of the cable main body 10 are on the same straight line. A color bar 2 is disposed within the second outer jacket 3 for distinguishing cable categories. The material used for the second reinforcing member 7 can be, but is not limited to, aramid fiber or other non-metal materials, and the like. In some possible other embodiments, the first reinforcement 5 may be replaced by other filling type materials or dry water-blocking type materials.

In this embodiment, the loose tube 6 is a dry loose tube, which does not need to be cleaned during the optical cable connection, thereby saving the installation cost. The loose tube 6 is made of water-blocking material, such as PBT/TPEE and the like, but not limited thereto.

It will be appreciated that the number of auxiliary reinforcing elements may be increased or decreased as desired, but at least two symmetrically arranged auxiliary reinforcing elements are included.

The novel optical cable 100 with the auxiliary strength members partially torn off at both sides may also be applied to indoor equipment components instead of indoor single-double core optical cables and butterfly cables.

It will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention. Thus, to the extent that such modifications and variations fall within the scope of the invention and the equivalent techniques thereof, it is intended that the present invention also encompass such modifications and variations.
