DETAILED DESCRIPTION

[0022] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0023] In the present disclosure, unless otherwise specified, the directional words used, such as "inside" and "outside", generally refer to the "inside" and "outside" relative to the corresponding component's own outline, and the terms "first" and "second" are used to distinguish one element from another element, and do not have order and importance. In addition, in the following description, when referring to the drawings, unless otherwise explained, the same figure numbers in different drawings represent the same or similar elements. The above definitions are only used to explain and illustrate the present disclosure and should not be understood as limitations on the present disclosure.

[0024] According to the specific implementation scheme provided by the present disclosure, Figures 1 to 3 As shown in the figure, an optical cable is provided, which includes a main body and a protective layer 1. The protective layer 1 is arranged on the outside of the main body and is coaxial with the main body. A light-emitting layer 2 is attached to the side of the main body facing the protective layer 1.

[0025] Through the above technical solution, in the optical cable provided by the present invention, the light-emitting layer 2 is attached to the side of the main body facing the protective layer 1. In this way, when the protective layer 1 of the optical cable is damaged and needs to be repaired during long-term use, the light emitted by the light-emitting layer 2 can pass through the damaged part and provide prompts to the staff at night or in dimly lit places, so that the staff can quickly locate the damaged part and improve the maintenance efficiency of the optical cable.

[0026] In the optical cable provided in the present disclosure, as an exemplary embodiment, reference is made to Figure 1 and Figure 2 As shown in , the number of the main bodies can be two, which are respectively constructed as the input optical cable 31 and the output optical cable 32. The protective layer 1 can be formed with a receiving space and include a partition 11. The partition 11 can be arranged in the receiving space and can divide the receiving space into two space units 12. The input optical cable 31 and the output optical cable 32 are respectively arranged in the two space units 12. In this way, the input optical cable 31 and the output optical cable 32 can be separated by the partition 11 to avoid direct contact and friction between the input optical cable 31 and the output optical cable 32 during long-term use, resulting in damage and failure of the light-emitting layer 2 on the surface of the input optical cable 31 and the output optical cable 32. In the case of damage to the protective layer 1, it cannot play a role in providing a reminder to the staff. Among them, the partition 11 can be made of any suitable material to achieve the purpose of separating the input optical cable 31 and the output optical cable 32 and providing a certain protection. The present disclosure does not make specific restrictions on this.

[0027] In the optical cable provided in the present disclosure, as an exemplary embodiment, reference is made to Figure 2As shown in , the optical cable may include a first buffer layer 4, which may be disposed between the protective layer 1 and the main body to fill the accommodation space. In this way, the first buffer layer 4 can prevent the light-emitting layer 2 from directly contacting and rubbing with the protective layer 1 during long-term use, which may cause the light-emitting layer 2 on the surface of the output optical cable 32 and the input optical cable 31 to be damaged and ineffective, and thus fail to provide a prompt to the staff. Among them, the first buffer layer 4 usually also has a semi-conductive property, which can effectively buffer and weaken the electric field strength, and effectively provide a buffering effect between the main body and the insulating layer 13 to prevent damage to the insulating layer 13. In the present disclosure, the first buffer layer 4 can further fix the position of the main body in the space unit 12, reduce the friction between the light-emitting layer 2 and the insulating layer 13, and prevent damage to the light-emitting layer 2. In addition, the first buffer layer 4 can be made of any suitable material, such as polyester fiber non-woven fabric and conductive carbon powder, etc., and the present disclosure does not make specific restrictions on this.

[0028] In the optical cable provided in the present disclosure, as an exemplary embodiment, reference is made to Figure 2 As shown in , the optical cable may include an insulating layer 13 coaxially arranged with the protective layer 1, and the insulating layer 13 is arranged on the side of the protective layer 1 facing the main body, which is used to ensure that the current, electromagnetic waves or light waves transmitted by the optical cable only propagate along the optical cable and do not flow to the outside world, while preventing contact and electric shock, and ensuring the safety of external objects and workers. Among them, the insulating layer 13 can be made of plastic materials or rubber materials, etc., and the present disclosure does not make specific restrictions on this.

[0029] In addition, a nameplate 8 can be provided on the outside of the protective layer 1, and the nameplate 8 is used to register the information of the optical cable during installation, wherein the nameplate 8 can be fixed to the outside of the protective layer 1 by bonding or the like, and the surface of the nameplate 8 can be coated with a luminous coating to facilitate the staff to check the optical cable information at night or in dim light.

[0030] In the optical cable provided in the present disclosure, as an exemplary embodiment, reference is made to Figure 1 As shown in the figure, the main body includes a cable body 5, a loose tube 6 and a second buffer layer 7. The cable body 5 and the loose tube 6 can be coaxially arranged from the inside to the outside, and the second buffer layer 7 can be filled between the cable body 5 and the loose tube 6. The loose tube 6 can protect the cable body 5 from damage and interference from the external environment, thereby ensuring the quality and stability of the optical cable transmission signal. The second buffer layer 7 also has semi-conductive properties, can effectively buffer and weaken the electric field strength, and effectively provide a buffering effect between the cable body 5 and the loose tube 6.

[0031] In the optical cable provided in the present disclosure, the loose tube 6 can be constructed in any suitable form, and the present disclosure does not impose any specific limitation on this. Figure 2As shown in the figure, the loose tube 6 may include a first inner protective layer 61, a thermal insulation layer 62, a waterproof layer and a first outer protective layer 64 which are coaxially arranged in sequence from the inside to the outside. That is to say, the loose tube 6 may be composed of the first inner protective layer 61, the thermal insulation layer 62, the waterproof layer and the first outer protective layer 64 to protect the cable body 5 from mechanical damage and chemical corrosion, from contact with water vapor and moisture, and from electrical breakdown due to low ambient temperature, so as to enhance the mechanical strength of the optical cable and extend the service life of the optical cable.

[0032] In the optical cable provided in the present disclosure, the cable body 5 can be constructed in any suitable form, and the present disclosure does not impose any specific limitation on this. Figure 2 As shown in the figure, the cable body 5 may include a reinforcing core 51, a cable core 52, an optical fiber 53 and a filling tube 54, and the cable core 52, the optical fiber 53 and the filling tube 54 may be arranged together around the circumference of the reinforcing core 51, wherein the number of the filling tubes 54 may be arbitrarily selected according to the number of the cable cores 52 and the optical fiber 53 and the radial size, that is, when the number of the cable cores 52 and the optical fiber 53 is large or the radial size is large so as to form a stable annular structure around the circumference of the reinforcing core 51, the filling tube 54 may not be arranged, and correspondingly, when the number of the cable cores 52 and the optical fiber 53 is small or the radial size is small, the structural stability of the cable body 5 is improved by adding the filling tube 54.

[0033] In the optical cable provided by the present disclosure, the optical fiber 53 can be constructed in any suitable form, and the present disclosure does not impose any specific limitation on this. Figure 3 As shown in the figure, the optical fiber 53 may include a fiber body 531, a second inner protective layer 532, a second outer protective layer 533 and a third buffer layer 534. The fiber body 531, the second inner protective layer 532 and the second outer protective layer 533 are coaxially arranged in sequence from the inside to the outside, and the third buffer layer 534 is filled between the fiber body 531 and the second inner protective layer 532. The third buffer layer 534 also has a semi-conductive property, which can effectively buffer and weaken the electric field strength, and effectively provide a buffering effect between the fiber body 531 and the second inner protective layer 532.

[0034] Among them, as an exemplary embodiment, the fiber body 531 may include a support column 5311 and several fiber cores 5312 arranged around the support column 5311. The fiber cores 5312 are usually thin filaments drawn from quartz, which are fragile and easy to break. Therefore, the support column 5311 can increase the mechanical strength of the fiber body 531 to a certain extent. Multiple fiber cores 5312 are arranged around the support column 5311. When one or several of the fiber cores 5312 are broken, the other fiber cores 5312 can still play a role in signal transmission, thereby improving the service life of the fiber body 531.

[0035] In addition, the body 531 may further include reinforcing ribs 5313 . The reinforcing ribs 5313 may be disposed on the outer side of the supporting column 5311 to further improve the mechanical strength of the body 531 .
