Description

Technical Field

[0001] The utility model belongs to the technical field of optical fiber cables, and particularly relates to a high-strength compression-resistant optical fiber cable. Background Art

[0002] Optical fiber cable is a telecommunication facility for transmitting optical signals. It is mainly composed of optical fiber and protective layer and is used for long-distance and high-bandwidth data communication. Announcement No. CN217060581U discloses an optical cable, including a central reinforcement layer placed in the center of the optical cable, and a centrally recessed rejection zone is arranged at a certain interval in the axial direction of the central reinforcement layer. The optical cable disclosed in the present invention meets the requirements of optical cable structural stability due to the central reinforcement layer arranged in the center of the optical cable, and can increase the tensile strength of the optical cable and improve the mechanical properties of the optical cable; at the same time, the centrally recessed rejection zone is arranged in the axial direction of the central reinforcement layer, which not only meets the requirements of optical cable structural stability, increases tensile strength, but also reduces the consumption of raw materials, avoids material waste, and reduces costs. Although this kind of optical cable has the effect of enhancing its tensile strength, it is lacking in the compression resistance of the optical cable. Since this kind of optical cable does not have a compression-resistant structure, it will cause the optical fiber line to be bent or squeezed to different degrees when it is subjected to uneven pressure, thereby causing light scattering or loss, and then leading to increased light attenuation, affecting the transmission quality and distance of the optical signal.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present utility model, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0030] In one embodiment of the present invention, Figure 1-5 As shown, a high-strength pressure-resistant optical fiber cable is provided, including an optical fiber body 1, a protective layer A2 is provided on the surface of the optical fiber body 1, a bracket A3 is fixedly installed on the surface of the protective layer A2, a filling block A4 is provided on the surface of the bracket A3, a tensile rope 5 is provided inside the filling block A4, a protective layer B6 is fixedly installed on the surface of the bracket A3, a bracket B8 is fixedly installed on the surface of the protective layer B6, a filling block B7 is provided on the surface of the bracket B8, an inner sleeve 9 is fixedly installed on the surface of the bracket B8, an anti-pressure block 10 is fixedly installed on the surface of the inner sleeve 9, and an outer sleeve 11 is fixedly installed on the surface of the anti-pressure block 10.

[0031] In the high-strength compression-resistant optical fiber cable of the utility model embodiment, when the optical fiber body 1 is subjected to pressure, the outer sleeve 11 will be supported by the compression-resistant block 10, and the bracket A3 and the bracket B8 will also support the inner sleeve 9, and the filling block A4 and the filling block B7 will protect the optical fiber body 1. The bracket A3, the bracket B8, the compression-resistant block 10, the filling block A4, the filling block B7, the protective layer A2, the protective layer B6 and the tension rope 5 play the role of improving the compression resistance while ensuring the tensile strength of the optical cable, thereby avoiding When the optical cable is bent due to pressure, its light attenuation increases, which affects the optical signal and the transmission quality and distance. When the optical cable is rolled up, the anti-wear strips 14 and the anti-wear plates 13 will provide anti-wear protection for the waterproof layer 12, and the waterproof layer 12 will waterproof the optical fiber body 1.

[0035] In another embodiment, Figure 1-5 As shown, the materials of the anti-wear plate 13 and the anti-wear strip 14 are both polyethylene. Specifically, the polyethylene material has good wear resistance and chemical stability, thereby playing an effect of protecting the waterproof layer 12.

[0036] In another embodiment, Figure 1-5 As shown, the material of the waterproof layer 12 is PVC material. Specifically, the PVC material has good waterproof performance and mechanical strength, and while achieving waterproof performance, it also improves the mechanical strength of the optical cable.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
