Description

Technical Field

[0001] The utility model relates to the technical field of optical fibers, in particular to an environment-friendly non-metallic flat ribbon optical cable. Background Technique

[0002] In the existing field of optical fiber technology, traditional optical cable designs often have some inherent problems and limitations. These optical cables may have deficiencies in mechanical strength, flexibility, waterproof and moisture-proof performance, and transmission stability, and cannot fully meet the requirements of modern complex and changeable application environments. Especially in occasions that require highly flexible cabling, long-term stable operation, and are sensitive to the influence of environmental factors, the performance of traditional optical cables is often unsatisfactory.

[0003] Specifically, traditional optical cable designs may lack sufficient mechanical strength and stability, and are easily damaged or deformed by external forces, thus affecting the transmission performance and service life of the optical cable. At the same time, traditional optical cables may also have deficiencies in flexibility and anti-bending ability, restricting their application in specific occasions. In addition, the lack of waterproof and moisture-proof performance may also cause the performance of the optical cable to decline in humid or underwater environments, and even lead to failures. In view of this, we propose an environment-friendly non-metallic flat ribbon optical cable. Content of the Utility Model

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1 - 3 , the present utility model provides a technical solution:

[0022] Environmentally friendly non-metallic flat ribbon optical cable, including an armor layer 1 as the main body. Inside the armor layer 1, there is a cable core 11. On the armor layer 1, there are a number of annular depressions 10 arranged at equal intervals. Between the armor layer 1 and the cable core 11, there is a strengthening layer 14. Between the cable core 11 and the strengthening layer 14, there is an inner protective layer 16. Between the inner protective layer 16 and the cable core 11, there is a loose tube 17. The loose tube 17 is closely attached to the cable core 11. The strengthening layer 14 includes a main body layer 140, and inside the main body layer 140, there is a braided layer 141. By setting the armor layer 1 as the main body and including the cable core 11 inside, the basic structure and protection function of the optical cable are realized. The design of the annular depressions 10 on the armor layer 1 enhances the flexibility and anti-bending ability of the optical cable. The setting of the strengthening layer 14 improves the mechanical strength and stability of the optical cable, while the inner protective layer 16 and the loose tube 17 provide additional protection for the cable core 11, ensuring the stability and security of optical fiber transmission. In addition, the braided layer in the strengthening layer 14 further enhances the tensile strength of the optical cable, making it more suitable for use in complex environments.

[0023] As a preference of this embodiment, an outer protective layer 12 is provided on the outer side of the armor layer 1. Setting the outer protective layer 12 on the outer side of the armor layer 1 provides additional waterproof, moisture-proof and physical protection for the optical cable, further enhancing the durability and stability of the optical cable.

[0024] As a preference of this embodiment, an interface layer 13 is provided between the armor layer 1 and the strengthening layer 14. Setting the interface layer 13 between the armor layer 1 and the strengthening layer 14 realizes a smooth transition between the two, enhances the bonding force between layers, and improves the overall structural stability of the optical cable.

[0025] As a preference of this embodiment, a filling layer 15 is provided between the strengthening layer 14 and the inner protective layer 16. The filling layer 15 provided between the strengthening layer 14 and the inner protective layer 16 can absorb and disperse external impacts, and at the same time prevent the internal optical fibers from being damaged due to vibration, further improving the transmission stability and security of the optical cable.

[0026] As a preference of this embodiment, the filling layer 15 is filled with a uniformly distributed water-absorbing material. The uniformly distributed water-absorbing material filled in the filling layer 15 can effectively absorb the moisture infiltrating into the optical cable, maintain a dry environment inside the optical cable, and prevent the influence of moisture on the optical fiber transmission performance.

[0027] As a preference of this embodiment, the outer protective layer 12 is closely attached to the surface of the armor layer 1, and the outer protective layer 12 is in close contact with the annular depressions 10. The design of the close attachment of the outer protective layer 12 to the surface of the armor layer 1 and the contact with the annular depressions 10 can increase the protective effect of the outer protective layer 12 on the armor layer 1.

[0028] Preferably in this embodiment, two cable cores 11 are provided in each armor layer 1, and each layer other than the outer protection layer 12 and the armor layer 1 is provided outside each cable core 11. The design of arranging two cable cores 11 in each armor layer 1 improves the transmission capacity and efficiency of the optical cable. At the same time, each cable core 11 is provided with protection structures of each layer other than the outer protection layer 12 and the armor layer 1, ensuring the independence and stability of each cable core 11 and improving the overall transmission performance of the optical cable.

[0029] When the environment-friendly non-metallic flat ribbon optical cable of the present utility model is in use, the core part of the optical cable is the cable core 11, which carries optical fibers and is responsible for high-speed and high-quality data transmission. In order to ensure the stability and safety of the cable core 11, the present utility model designs multiple protection structures.

[0030] First of all, the cable core 11 is tightly wrapped by the loose tube 17, which provides the first layer of buffering and protection for the optical fiber, preventing the optical fiber from being directly damaged due to external pressure or tension. The design of the loose tube 17 also allows the optical fiber to have a certain amount of movement space when subjected to external forces, thereby reducing the stress generated by the external forces on the optical fiber.

[0031] Then, the inner protection layer 16 further enhances the protection of the cable core 11. It can not only resist a certain degree of physical impact.

[0032] Outside the cable core 11 and the inner protection layer 16 is the strengthening layer 14. The strengthening layer 14 is composed of a main body layer 140 and a braided layer. The main body layer 140 provides basic structural support, while the braided layer 141 greatly enhances the tensile strength and toughness of the optical cable through its intertwined structure. This design enables the optical cable to maintain the integrity of its structure when subjected to tensile force or twisting, and is not easily broken or deformed.

[0033] Outside the strengthening layer 14, the armor layer 1 provides more solid protection for the optical cable. The annular depression 10 on the armor layer 1 not only increases the flexibility of the optical cable, making it easier to route and install, but also reduces the weight of the optical cable and the installation cost.

[0034] In addition, the connection layer 13 is located between the armor layer 1 and the strengthening layer 14, which ensures the tight combination between these two layers, prevents relative movement between layers, and thus improves the overall stability of the optical cable.

[0035] The filling layer 15 is located between the strengthening layer 14 and the inner protection layer 16. Its main function is to absorb and disperse external impacts and reduce the influence of vibration on the internal optical fiber. The water-absorbing material evenly distributed in the filling layer 15 can also effectively absorb the moisture infiltrating into the optical cable and keep the inside of the optical cable dry, thereby ensuring the stability and efficiency of optical fiber transmission.

[0036] Finally, the outer protective layer 12 is closely attached to the outside of the armor layer 1, providing the outermost waterproof, moisture-proof and physical protection for the optical cable. The close attachment between the outer protective layer 12 and the armor layer 1 enhances the overall structural strength of the optical cable, enabling it to work stably for a long time in various harsh environments.

[0037] In summary, through the design of multiple protection structures, the environmentally friendly non-metallic flat ribbon optical cable of the present utility model ensures the stability and security of optical fiber transmission, enabling it to exhibit excellent performance in various complex environments.

[0038] The above shows and describes the basic principles, main features and advantages of the present utility model.
