Technical Field

[0001] The present invention relates to the technical field of optical fiber outer diameter testing, and more specifically, to an optical fiber outer diameter testing method and testing equipment prepared by a heat-resistant optical cable for a data center. Background Art

[0002] Practical optical fiber is a glass fiber slightly thicker than a human hair. The outer diameter of the optical fiber used for communication is generally 125-140μm. The optical fiber generally refers to a core and a cladding. The core completes the transmission of the signal. The cladding has a different refractive index from the core, which seals the optical signal in the core for transmission and protects the core. In engineering, multiple optical fibers are generally fixed together to form an optical cable. Fiber optic cable is a communication cable consisting of two or more glass or plastic optical fiber cores. These optical fiber cores are located in a protective coating and covered by a plastic PVC outer casing. Signal transmission along the internal optical fiber generally uses infrared rays.

[0003] In the application of optical fiber, there are many types of optical fiber itself, but the basic test methods of optical fiber and its system are generally the same, and the equipment used is also basically the same. The basic test contents of optical fiber or optical fiber system are: continuity and attenuation / loss, measuring optical fiber input power and output power, analyzing optical fiber attenuation / loss, determining optical fiber continuity and the location where light loss occurs, etc.

[0004] At present, there are many problems in testing the outer diameter of optical fiber. When the outer diameter of optical fiber is tested by pulling, its outer surface will often bulge or dent, so there is an optical fiber with different outer diameter lengths, which is prone to line failure in subsequent use.

[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0037] Embodiment 1:

[0038] The method for testing the outer diameter of an optical fiber prepared by a heat-resistant optical cable for a data center comprises the following steps:

[0039] S1. Prepare the optical fiber to be tested and the optical fiber testing equipment compatible with the optical fiber;

[0040] S2. Insert the optical fiber to be tested into the optical fiber testing equipment, and pull it by holding one end to make the optical fiber continue to pass through the equipment for testing and inspection;

[0041] S3. When the outer diameter of the optical fiber is uneven or different, it will be tested and marked by the equipment;

[0042] S4. Finally, the staff will process according to the marks and conduct a second retest after confirming that there are no errors.

[0043] See also Figure 1The optical fiber testing equipment includes: a supporting base 1, a testing ring 3 and a dipping cotton 5. The supporting base 1 is made of a composite load-bearing plate. The bottom of the supporting base 1 is a weighted plate for stabilizing the overall testing equipment, which can be disassembled separately during transportation. A pair of fixing frames 2 are fixedly connected to the upper end of the supporting base 1. The testing ring 3 is fixedly installed in the middle of the pair of fixing frames 2. The fixing installation method here is fixed by bolts, which is convenient for removing it for maintenance and replacement later. An optical fiber body 4 is arranged in the middle of the testing ring 3.

[0044] See also Figure 2 The test ring 3 includes a fixed outer ring 31, which is fixedly installed in the middle of a pair of fixed frames 2. The inner end of the fixed outer ring 31 is fixedly connected to a detection inner ring 32, and the inner end of the detection inner ring 32 is fixedly connected to an electromagnetic ring 33. The electromagnetic ring 33 applies magnetic force to the detection inner ring 32, so that the detection inner ring 32 is subjected to force to detect the outer surface of the optical fiber body 4.

[0045] See also Figure 3 The detection inner ring 32 includes an extrusion component 321, which is fixedly connected to the inner end of the electromagnetic ring 33. A test ball 322 is installed at the end of the extrusion component 321 away from the electromagnetic ring 33. A sponge pad 323 is provided between the electromagnetic ring 33 and the test ball 322. When a large protrusion appears, the test ball 322 will still be squeezed into the sponge pad 323 after counteracting the magnetic force, thereby preventing the detection inner ring 32 from being damaged by excessive squeezing force.

[0046] See also Figure 3-5 The extrusion assembly 321 includes a support rod 3211, which is fixedly connected to the inner end of the electromagnetic ring 33. The end of the support rod 3211 away from the electromagnetic ring 33 is fixedly connected to the extrusion block 3212. The end of the support rod 3211 close to the extrusion block 3212 is provided with a placement hole 3213, and the marking ball 7 is located in the placement hole 3213 and supported by the support rod 3211, so that the marking ball 7 is squeezed upward by the extrusion block 3212, so that it is broken and liquid flows out for marking.

[0047] Please continue reading Figure 4 The test ball 322 includes a half magnetic block 3221, which is installed at the lower end of the detection inner ring 32. The lower end of the half magnetic block 3221 is fixedly connected with a half cotton bottom 3222. A plurality of liquid seepage holes are opened in the middle of the half cotton bottom 3222. Through the interaction force between the half magnetic block 3221 and the electromagnetic ring 33, the test ball 322 is tightly attached to the outer surface of the optical fiber body 4 for detection.

[0048] See also Figure 4 , Figure 5 and Figure 8The extrusion component 321 is fixedly connected to one end near the marking ball 7 with a crushing block 9, and the crushing block 9 includes a puncture block 91, which is fixedly connected to the extrusion component 321. The upper end of the puncture block 91 is fixedly connected with puncture-proof cotton 92. When the crushing block 9 is subjected to force, the puncture-proof cotton 92 is compressed, so that the puncture block 91 protrudes to facilitate puncturing of the marking ball 7.

[0049] See also Figure 4 , Figure 6 and Figure 7 The liquid-dipping cotton 5 is arranged in the test ball 322, and a receiving box 6 is fixedly connected in the middle of the liquid-dipping cotton 5. The extrusion component 321 passes through the receiving box 6 and is slidably connected thereto. A plurality of marking balls 7 are arranged in the receiving box 6, and the marking balls 7 include a water-soluble film 71, and the water-soluble film 71 is arranged in the receiving box 6. An easily breakable waterproof wax coating 72 is fixedly connected to the inner end of the water-soluble film 71, and the easily breakable waterproof wax coating 72 is filled with a marking liquid 73. The marking liquid 73 is made of a mixture of pigment and alcohol. The upper half of the marking ball 7 in the receiving box 6 and the lower half of the marking ball 7 use different pigments. Through the two different pigments, different places of the depression and the protrusion can be marked respectively. The marking is carried out to distinguish them and facilitate subsequent processing. Liquid outlets are opened in the middle of the upper and lower ends of the container box 6. The marking liquid 73 is allowed to flow out by squeezing and breaking the breakable waterproof wax coating 72 or puncturing the water-soluble film 71. The liquid is absorbed by the liquid cotton 5 from the liquid outlet and discharged from the liquid seepage hole for marking. The marking liquid 73 here adopts a mixed material so that the marking liquid 73 can be easily evaporated and dried while the pigment is used for marking, thereby preventing the residual liquid in the liquid cotton 5 from affecting the secondary marking. A spring 8 is installed in the container box 6, and the spring 8 is in contact with the marking ball 7. The used marking ball 7 is filled by the elastic force of the spring 8.

[0050] See also Figure 9-10 A pair of auxiliary frames 10 are fixedly connected to the upper end of the support base 1, and an auxiliary cylinder 11 is fixedly connected in the middle of the pair of auxiliary frames 10, and the pair of auxiliary cylinders 11 are respectively located at the front and rear ends of the test ring 3. The optical fiber body 4 passes through the auxiliary cylinder 11, and the optical fiber body 4 is straightened and smoothed by the pair of auxiliary cylinders 11 to prevent the optical fiber body 4 from being easily bent or arched during the pulling process, thereby affecting the test and easily misleading the test results. The auxiliary cylinder 11 includes a guide cylinder 111, which is fixedly installed at the front and rear ends of the test ring 3. A plurality of rolling grooves are opened on the inner wall of the guide cylinder 111, and a rolling ball 112 is fixedly connected in the rolling groove. The addition of the rolling ball 112 can not only reduce friction, but also make the optical fiber body 4 smoother during the pulling test, thereby greatly accelerating the test efficiency.

[0051] Working principle: After the optical fiber body 4 passes through the auxiliary tube 11 on one side, it passes through the test ring 3 and then passes through another auxiliary tube 11, and then the electromagnetic ring 33 is powered on to use the magnetic force to repel the test ball 322, so that the test ball 322 is close to the outer surface of the optical fiber body 4. Then the staff pulls the optical fiber body 4. When a bulge appears on the surface of the optical fiber body 4, the test ball 322 is squeezed and pressed into the sponge pad 323. Under the repulsion of the magnetic force, the marking ball 7 in the test ball 322 is squeezed and pierced by the piercing block 91 to flow out the marking liquid 73, and the marking liquid 73 flows out and is dipped in the liquid cotton. After absorption, the semi-cotton bottom 3222 applies it to the raised part for marking. When a depression appears, the test ball 322 is forced to move toward the depressed part under the magnetic force of the electromagnetic ring 33. At the same time, the marking ball 7 is also squeezed and punctured by the puncture block 91, so that the marking liquid 73 flows out and is also marked. After the marking ball 7 is punctured and used, a marking ball 7 is refilled to the detection position under the elastic force of the spring 8 until the number is used up. Here, the test ring 3 is made of transparent material as a whole, which is convenient for the staff to observe the number of marking balls 7 used, thereby facilitating subsequent replacement and filling.

[0052] Compared with the prior art, the advantages of the present invention are:

[0053] This solution can achieve the purpose of testing the outer diameter of the optical fiber body 4 passing through the test ring 3. The test ball 322 is repelled by the magnetic force of the electromagnetic ring 33. When the test ball 322 tests a concave part of the outer diameter of the optical fiber, the accommodating box 6 is pressed down as a whole under the action of the magnetic force and the marking ball 7 is squeezed to break it, so that the marking liquid 73 flows out and is absorbed by the dipped cotton 5 and then squeezed out from the seepage hole, marking the concave part for reminder. At the same time, when a bulge is tested, the bulge squeezes the test ball 322, and the squeezing component 321 also squeezes the marking ball 7 to let the marking liquid 73 flow out, and the bulge is also marked, thereby effectively improving the testing capability and testing efficiency.

[0054] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
