[0002] Optical fiber is a key transmission medium in optical communications technology. During use, optical fiber is inevitably subject to environmental influences such as temperature and humidity. Therefore, it is necessary to test the transmission performance of optical fiber in various temperature and humidity environments. Before delivery, optical fiber undergoes temperature cycling testing to determine the attenuation stability of the delivered fiber to the temperature and humidity fluctuations it may experience during storage, transportation, and use.

[0003] Currently, the national standard GB / T15972.5-2008 stipulates the requirements for preparing temperature cycling test specimens: Class A optical fibers must be no shorter than 1000m, and Class B optical fibers must be no shorter than 2000m. During the temperature cycling test, the winding diameter of the sample optical fiber must be much larger than the diameter of the delivered optical fiber reel, and multiple sample optical fibers must be prepared. The sample optical fibers must be loosely wound into coils and placed in a climate chamber. Currently, the method for preparing temperature cycling test specimens is to loosely wind multiple sample optical fibers into coils and hang them in a climate chamber. However, this existing method has the following problems: 1. Wind from the climate chamber's air outlet can easily cause the sample optical fibers to vibrate, affecting test results; 2. The hung sample optical fibers are pulled and cannot be relaxed; 3. The sample optical fibers are inconvenient to remove and place. Utility Model Content

[0029] Example 1

[0030] This embodiment provides a layout device for optical fiber temperature and humidity testing, such as Figure 1 As shown, it includes a frame 100, on which at least one support member 200 is provided, and on which a plurality of ventilation holes 210 are provided. The support member 200 has a support surface 230 for laying out the wound optical fiber to be tested, and on which two clamps 300 arranged in an upper and lower arrangement are provided, and the two clamps 300 are respectively used to clamp the first end and the second end of the wound optical fiber to be tested.

[0031] This embodiment provides a placement device for optical fiber temperature and humidity testing. During use, the support member 200 is set on the frame 100, and the support surface 230 can place different sizes of wound optical fibers to be tested. The wound optical fiber to be tested is laid flat on the support surface 230, and the first end and the second end of the wound optical fiber to be tested are clamped by two clamps 300 arranged up and down respectively so that the first end and the second end of the wound optical fiber to be tested are arranged up and down, ensuring that the first end and the second end of the wound optical fiber to be tested are placed neatly, and the first end and the second end of the wound optical fiber to be tested are conveniently passed through the circular holes on both sides of the climate chamber to connect to the light source and the power meter. The frame 100 is placed in the climate chamber. When the temperature and humidity test of the wound optical fiber to be tested is completed, the two clamps 300 are opened and the wound optical fiber to be tested is taken out.

[0032] This embodiment provides a layout device for optical fiber temperature and humidity testing, which allows the coiled optical fiber to be tested to be coiled and tested in a climate chamber. This ensures that the coiled optical fiber to be tested is always in a relaxed state and is not easily pulled. It also prevents the wind in the climate chamber from causing the coiled optical fiber to be tested to vibrate and affect the test results. In addition, in this embodiment, two clamps 300 are provided on the support member 200. The two clamps 300 are respectively used to clamp the first end and the second end of the coiled optical fiber to be tested, which ensures that the coiled optical fiber to be tested can be easily taken out and placed.

[0033] In this embodiment, in order to ensure that the support member 200 is disposed on the support surface 230 and does not slide easily, the support surface 230 is a support plane.

[0034] In this embodiment, the support member 200 is detachably connected to the frame 100 , such as by threaded connection, snap connection, or sliding connection, etc., which is not limited in this embodiment.

[0035] In the specific implementation of this embodiment, Figure 1-Figure 3 As shown, the support member 200 is slidably connected to the frame 100 to facilitate the placement and removal of the coiled optical fiber to be tested.

[0036] In this embodiment, Figure 1-Figure 3 As shown, a first sliding mechanism 130 is provided on the frame 100, and a second sliding mechanism 520 that cooperates with the first sliding mechanism 130 is provided on the support member 200. The second sliding mechanism 520 slides and cooperates with the first sliding mechanism 130 to move the support member 200 out of the frame 100 or into the frame 100. When the support member 200 moves out of the frame 100, it is convenient to take and place the wound optical fiber to be tested. When the support member 200 moves into the frame 100, it is convenient to wind the wound optical fiber to be tested into a circle for experiments in the climate chamber.

[0037] Specifically, the first sliding mechanism 130 is a sliding groove 131, and the second sliding mechanism 520 is a sliding member 221 slidably connected to the sliding groove 131. The sliding member 221 slides relative to the sliding groove 131 to move the support member 200 out of the frame 100 or into the frame 100, thereby making the support member 200 detachably connected to the frame 100.

[0038] In this embodiment, Figure 1 and Figure 2 As shown, the frame body 100 is welded into a frame structure by a plurality of support rods 110, and the slide groove 131 is fixed to the frame body 100. In a specific implementation of this embodiment, the support rods 110 are vertically arranged support rods 110 or horizontally arranged support rods 110, and four horizontally arranged support rods 110 are surrounded to form a rectangular frame structure. The four vertically arranged support rods 110 are fixed to the bottom or top of the rectangular frame structure to support the rectangular frame structure, and the slide groove 131 is fixed to the horizontal support rods 110.

[0039] In this embodiment, Figure 1-Figure 3 As shown, in order to facilitate the support member 200 to move out of the frame 100 or move into the frame 100, at least one group of slide grooves 131 is set on the frame 100, each group of slide grooves 131 includes multiple slide grooves 131, and each support member 200 is provided with a group of sliding members 221, and the multiple slide grooves 131 in a group of slide grooves 131 are slidably connected with the multiple sliding members 221 on a group of sliding members 221 in a one-to-one correspondence.

[0040] Specifically, if Figure 1-Figure 3 As shown, in a specific implementation of an embodiment of the present invention, a group of slide grooves 131 includes two oppositely arranged slide grooves 131, and two oppositely arranged sliding members 221 are arranged on both sides of the support member 200. Each sliding member 221 is slidably connected to a slide groove 131 to facilitate the support member 200 to move out of the frame 100 or move into the frame 100.

[0041] In a specific implementation of this embodiment, the slide groove 131 supports the sliding member 221, and further supports the support member 200, to ensure that the support member 200 can be stably placed on the frame 100. By providing multiple slide grooves 131, the support frame can be supported at multiple points, ensuring the stability of the support member 200 and preventing the support member 200 and the optical fiber to be tested thereon from shaking and affecting the test results.

[0042] In this embodiment, Figure 1-Figure 3As shown, the slide groove 131 has a first end 1311 and a second end 1312 disposed opposite each other. The sliding member 221 slides from the first end 1311 to the second end 1312 to move the support member 200 into the slide groove 131. When the sliding member 221 moves into the slide groove 131, the slide groove 131 supports the sliding member 221. The sliding member 221 slides from the second end 1312 to the first end 1311 to move the support member 200 out of the slide groove 131.

[0043] In this embodiment, Figure 1-Figure 3 As shown, in order to further ensure that the jitter of the support member 200 and the wound optical fiber to be tested on the support member 200 affects the test results, it is necessary to ensure the stability of the support member 200, and the first end 1311 is provided with a accommodating chamber 132 protruding from the slide groove 131, and the accommodating chamber 132 is connected to the slide groove 131, and the second pulley 133 is rotatably connected in the accommodating chamber 132, and the first pulley 222 is rotatably connected to the sliding member 221, and the sliding member 221 slides relative to the slide groove 131 so that the first pulley 222 can selectively abut against the second pulley 133.

[0044] Specifically, in the initial state, when the support member 200 is not set on the frame 100, the first pulley 222 and the second pulley 133 are not in contact. When the sliding member 221 slides from the first end 1311 to the second end 1312, the first pulley 222 rolls relative to the second pulley 133 and the support member 200 is tilted at a certain angle. The first pulley 222 rolls relative to the second pulley 133 so that the first pulley 222 enters the sliding groove 131. When the first pulley 222 rolls into the sliding groove 131, the first pulley 222 222 abuts against the second pulley 133 to clamp the support member 200 and prevent the support member 200 from falling from the frame 100; when the support member 200 needs to be disassembled, the first pulley 222 is rolled relative to the second pulley 133 and the support member 200 is tilted at a certain angle. The first pulley 222 rolls relative to the second pulley 133 to make the first pulley 222 come out of the slide groove 131, and the sliding member 221 slides from the second end 1312 to the first end 1311, and the support member 200 is set on the frame 100.

[0045] In a specific implementation of this embodiment, the accommodating cavity 132 is a cavity structure with a trumpet-shaped or other shaped cross section, which is not limited in this embodiment.

[0046] In this embodiment, Figure 1-Figure 3 As shown, the slide groove 131 serves as a supporting portion to support the frame 100 . The cross section of the slide groove 131 is U-shaped. When the sliding member 221 moves into the slide groove 131 , the slide groove 131 supports the sliding member 221 and further supports the support member 200 .

[0047] In this embodiment, other supporting parts may be further provided on the frame 100 to support the supporting member 200 , which is not limited in this embodiment.

[0048] In this embodiment, Figure 1-Figure 3 As shown, the frame 100 is provided with an abutment member 120, and the support member 200 can selectively abut against the abutment member 120. When the sliding member 221 slides from the first end 1311 to the second end 1312, the support member 200 abuts against the abutment member 120 to limit the support member 200 so that the support member 200 is disposed in the frame 100.

[0049] In the specific implementation of this embodiment, Figure 2 As shown, the abutment member 120 is a vertically arranged abutment rod.

[0050] In this embodiment, Figure 1-Figure 3 As shown, the slide groove 131 is tilted at a certain angle relative to the frame 100, so that the support member 200 is tilted at a certain angle and arranged in the frame 100 to prevent the support member 200 from falling out. The support member 200 can be embedded in place along the slide groove 131 by its own gravity, playing a locking role and preventing the support member 200 from sliding out.

[0051] In this embodiment, Figure 1 and Figure 4 As shown, the clamp 300 includes a first clamping portion 310 and a second clamping portion 320 . The first clamping portion 310 and the second clamping portion 320 move closer to or farther from each other to clamp or release the first end or the second end of the coiled optical fiber to be tested.

[0052] In this embodiment, the first clamping portion 310 and the second clamping portion 320 are hinged, and the first clamping portion 310 or the second clamping portion 320 is fixed to the support member 200 .

[0053] In this embodiment, Figure 4 As shown, a clamping groove 311 is provided inside either the first clamping portion 310 or the second clamping portion 320, and a clamping block 321 is provided inside the other of the first clamping portion 310 or the second clamping portion 320. The clamping block 321 is engaged with the clamping groove 311 to clamp the first end or the second end of the wound optical fiber to be tested. The edge of the clamping groove 311 is provided with a chamfer to prevent the first end or the second end of the wound optical fiber to be tested from being pulled and damaged when placed in the clamping groove 311.

[0054] Specifically, the clamping block 321 is made of silicone. On the one hand, the clamping block 321 cooperates with the clamping groove 311 to clamp the wound optical fiber to be tested. On the other hand, the flexibility of the silicone prevents the wound optical fiber to be tested from being crushed and increases friction.

[0055] In this embodiment, Figure 4As shown, the clamping groove 311 includes a first clamping groove 3111, a second clamping groove 3112 and a third clamping groove 3113. The first end or the second end of the wound optical fiber to be tested is placed in the first clamping groove 3111, the second clamping groove 3112 and the third clamping groove 3113 in sequence. The first clamping groove 3111 is an arc-shaped groove, which is convenient for the initial placement of the first end or the second end of the wound optical fiber to be tested. The second clamping groove 3112 and the third clamping groove 3113 are both V-shaped grooves and the second clamping groove 3112 is smaller than the third clamping groove 3113 to facilitate the clamping and positioning of the first end or the second end of the wound optical fiber to be tested.

[0056] In this embodiment, Figure 4 As shown, the clamping block 321 includes a first clamping block 3211 and a second clamping block 3212. The first clamping block 3211 is engaged with the first clamping groove 3111 to initially clamp the wound optical fiber to be tested, and the second clamping block 3212 is engaged with the third clamping groove 3113 to finally clamp the wound optical fiber to be tested.

[0057] In this embodiment, Figure 4 As shown, a first adsorption component 312 is provided on the first clamping portion 310, and a second adsorption component 322 is provided on the second clamping portion 320. The first adsorption component 312 and the second adsorption component 322 are adsorbed and connected to clamp the first end or the second end of the wound optical fiber to be tested. The first adsorption component 312 and the second adsorption component 322 are adsorbed to each other, thereby increasing the clamping effect of the first clamping portion 310 and the second clamping portion 320 on the wound optical fiber to be tested. Specifically, the adsorption component 330 can be a magnetic material, which is not limited in this embodiment.

[0058] In this embodiment, a plurality of ventilation holes 210 are arranged in a matrix on the support member 200 so as to evenly dissipate heat when the coiled optical fiber to be tested is subjected to a temperature and humidity test.

[0059] The method of using this embodiment is:

[0060] Step 1: Place the frame 100 into a climate chamber;

[0061] Step 2: Place the fiber optic reel to be tested on the support surface 230 of the support member 200. Fix the first and second ends of the fiber optic reel to be tested on two fixtures 300, respectively, with 2-3 m of the ends exposed. Label the fiber optic reel to be tested with the sample code.

[0062] Step 3: Secure the middle part of the coiled optical fiber to be tested with tape;

[0063] Step 4: Push the support member 200 into the frame 100 at an angle;

[0064] Step 5: Pass the first and second ends of the coiled optical fiber to be tested through the circular holes on both sides of the climate chamber and connect them to the light source and the power meter;

[0065] Step 6: Start the test and record the test parameters.

[0067] In this embodiment, Figure 1 As shown, the number of supports 200 is greater than two. All supports 200 are arranged on the frame 100 at a predetermined distance from top to bottom, allowing multiple supports 200 to accommodate multiple coiled optical fibers to be tested. All fixtures 300 are arranged at a predetermined distance from top to bottom, ensuring that all fixtures 300 are aligned. Layering multiple coiled optical fibers to be tested facilitates the removal of samples with poor test results. Furthermore, the support members 200 are equipped with multiple ventilation holes, ensuring good ventilation throughout the device and uniform temperature and humidity of the coiled optical fibers to be tested on each layer of support members 200.
