The wrapping layer 12, the coating layer 13 and the outer sheath 14 are sequentially arranged outside the fiber core 11. The line searching core 15 is spirally arranged and completely wrapped outside the coating layer 13.

[0031] The wrapping layer 12 has a lower refractive index than the fiber core 11, and is used for limiting the transmission of optical signals in the fiber core 11. The outer sheath 14 is made of transparent material or yellow material. In the embodiment, the outer sheath 14 is made of transparent material, so that the brightness of the line searching core 15 can be observed by an operator during subsequent line searching operation.

[0032] In practical application, the fiber core 11 and the wrapping layer 12, the wrapping layer 12 and the coating layer 13 are fixed by high-temperature extrusion, ensuring stable connection and good optical performance; the coating layer 13 and the tracing fiber core 15 are fixed by spiral winding + ultraviolet curing adhesion, ensuring stable spiral structure of the tracing fiber core 15 and high red light transmission efficiency; the tracing fiber core 15 and the outer sheath 14 are fixed by high-temperature extrusion, ensuring stable connection and good protection effect of the outer sheath 14.

[0033] Referring to Figure 3 and Figure 4 , the first adapter 2 and the second adapter 3 are respectively provided with a first tracing observation window 201 and a second tracing observation window 301, and the two ends of the tracing fiber core 15 are respectively arranged in the first tracing observation window 201 and the second tracing observation window 301.

[0034] Specifically, referring to Figure 3 , the first adapter 2 is used for connecting the FC interface, the first adapter 2 includes an FC adapter 21, a nut sleeve 22, a ceramic ferrule 23 and a dust cap 24, the first tracing observation window 201 is arranged on the FC adapter 21, and the end of the outer sheath 14 of the connection cable 1 away from the second adapter 3 is connected with the FC adapter 21; the FC adapter 21 is provided with the nut sleeve 22 at the end away from the connection cable 1, which is a threaded fastening part and is used for screwing and fixing when connecting the FC interface; the ceramic ferrule 23 is arranged inside the FC adapter 21 and connected with the fiber core 11, the tracing fiber core 15 is arranged to extend into the FC adapter 21 and arranged inside the first tracing observation window 201 following the fiber core 11; the dust cap 24 is arranged outside the ceramic ferrule 23, which protects the end face of the ceramic ferrule 23 from being contaminated or damaged when the FC adapter 21 is inserted.

[0035] Referring to Figure 4 , the second adapter 3 is used for connecting the LC interface, the second adapter 3 includes an LC adapter 31, a first sleeve 32, an elastic buckle 33 and a ceramic sleeve 34, the first sleeve 32 connected with the outer sheath 14 is arranged on the LC adapter 31, and the second tracing observation window 301 is arranged on the first sleeve 32; the end of the tracing fiber core 15 away from the first adapter 2 is arranged to extend into the LC adapter 31 and arranged inside the second tracing observation window 301 following the fiber core 11; in addition, the elastic buckle 33 is arranged on the LC adapter 31, which is used for quick clamping and unlocking when the LC adapter 31 is inserted and pulled out; the end of the LC adapter 31 away from the outer sheath 14 is further fixed with the ceramic sleeve 34, which is used for wrapping and protecting the ceramic ferrule inside the fiber connector.

[0036] It should be noted that the first adapter 2 and the second adapter 3 are both devices that can be directly purchased in the market.

[0037] The working principle of the embodiment is as follows: in use, the FC adapter 21 is connected with the FC interface of the external device, and the nut sleeve 22 is rotated to complete the threaded fixing, and the LC adapter 31 is connected with the LC interface of the external device, and the elastic buckle 33 is matched to complete the clamping fixing.

[0038] In the working state, the stable transmission of the optical signal is completed through the cooperation of the ceramic ferrule 23 on the first adapter 2, the optical fiber core 11 and the ceramic ferrule in the optical fiber connector.

[0039] Specifically, when the line searching operation needs to be performed, the operator only needs to insert the red light pen into the first line searching observation window 201 or the second line searching observation window 301, and the red light passes through the line searching fiber core 15, and the red light is generated in the other line searching observation window, so that the line searching operation can be quickly realized.

[0040] When the line searching operation is performed, if there is no red light feedback in one of the first line searching observation window 201 and the second line searching observation window 301, it indicates that the jumper fiber is damaged, and the red light in the line searching fiber core 15 will be emitted from the damaged position, so that the operator can quickly find the damaged position of the jumper fiber and realize real-time feedback of the damage state, which has the effect of preventing the jumper fiber from being damaged and greatly reduces the operation and maintenance cost and the fault recovery time.
