[0004] To address the aforementioned problems, the purpose of this utility model is to disclose a biological protection optical cable, which is achieved using the following technical solution.

[0007] The outer edge of the skeleton is provided with n pairs of spiral skeleton grooves, and the two third sleeves of the combined sleeve are respectively inserted into the corresponding pair of skeleton grooves;

[0008] An independent sleeve is also inserted between two adjacent combined sleeves, and at least one optical fiber is installed in the first sleeve, the third sleeve and the independent sleeve.

[0009] The aforementioned biological protective optical cable has a third connecting component consisting of two first connecting components and a second sleeve. The second sleeve is located between the two first connecting components and between the two third sleeves and the two first sleeves. The second sleeve is connected to the first sleeve through a first connecting component. The distance between the two first sleeves is greater than the distance between the two third sleeves. At least one optical fiber is provided inside the second sleeve.

[0010] The aforementioned biological protection optical cable includes a butterfly unit between the two first sleeves of the combined sleeve. The butterfly unit consists of a butterfly unit sheath, two reinforcing members, and at least one optical fiber. The reinforcing members and the optical fiber are located inside the butterfly unit sheath, and the optical fiber is located between the two reinforcing members.

[0011] The aforementioned biological protective optical cable has a butterfly-shaped unit sheath made of flame-retardant polyolefin.

The inner diameter of the receiving groove is larger than the distance between the two third sleeves. An independent sleeve is provided in the receiving groove, and at least one optical fiber is provided in the independent sleeve.

[0024] 1. The combined sleeve is made of multiple sleeves connected together, integrally formed, and easy to process.

[0025] 2. When the combined sleeve has a second sleeve, the second sleeve does not directly contact the frame, so that the optical fiber inside the second sleeve will not be affected when the optical cable is squeezed. In emergency use, it can ensure normal communication of the optical fiber inside the second sleeve as much as possible.

[0026] 3. The butterfly unit only contacts the two first connecting parts and does not contact the second sleeve, further preventing the optical fiber inside the second sleeve from being affected when the optical cable is squeezed.

[0027] 4. The optical cable contains both loose tubes and butterfly units, which can meet the needs of both outdoor and indoor laying.

[0028] 5. When the combined sleeve does not have a second sleeve, the first connecting component can effectively protect the optical fiber in the independent sleeve in the receiving slot from being affected.

[0029] 6. It has a dual rodent-repellent function. The outer protective layer contains microcapsule particles containing rodent repellent, and there is a twisted steel wire anti-gnawing component between the outer protective layer and the wrapping layer.

[0030] 7. The combined sleeve is composed of multiple sleeves, which can hold different optical fibers in different sleeves, resulting in a higher fiber core density in the optical cable.

[0031] 8. An independent sleeve is also provided between two adjacent combined sleeves. The independent sleeve does not contact the anti-gnawing components and the skeleton. When the optical cable is under pressure, the pressure on the optical fiber inside the independent sleeve is greatly reduced. Attached Figure Description
