Technical Field
[0001] The present application relates to the field of optical fiber communication technology, and in particular to an optical fiber polarization control device. Background Art

In optical fiber communications and sensing systems, the polarization state of light has an important influence on signal transmission and detection. A fiber polarization controller can achieve precise control of the polarization state of light, thereby improving the performance and stability of the system.
[0003] In the related art, when changing the polarization direction of light, the optical fiber polarization controller needs to adjust the angle of the wave plate on the controller to change the polarization direction of light. Most of the existing controllers are very inconvenient when adjusting the angle of the wave plate, which makes the whole process of adjusting the polarization direction of light through the controller more cumbersome and inconvenient. At the same time, the adjustment angle of the wave plate on the controller is limited, which in turn limits the flexibility of adjusting the polarization direction of light, which is not conducive to its daily use.

DETAILED DESCRIPTION
[0032] The following is combined with Figure 1 -Attached Figure 3 , further details of this application are given.
[0033] Example:
[0034] The present application discloses a fiber polarization control device. Figure 1 and Figure 2 , including a base 1, the base 1 is in a rectangular shape, and a plurality of support platforms 2 are evenly installed on the top of the base 1 along its length direction, and these support platforms 2 are fastened to the base 1 by fastening bolts. A wave plate 3 is rotatably installed between two adjacent support platforms 2, and a long strip threading channel 4 is opened at the bottom of the wave plate 3 in the horizontal direction, and a circular wire storage channel 5 is opened along the side of the side wall of the wave plate 3, and the threading channel 4 and the wire storage channel 5 are opened on the same side of the wave plate 3, and the bottom of the wire storage channel 5 is connected to the threading channel 4, and the threading channels 4 between two adjacent wave plates 3 are connected.
[0035] At the same time, refer to Figure 1 and Figure 2 The supporting platforms 2 at the left and right ends of the top of the base 1 are both installed with threading platforms 6 on the sides away from each other through fastening bolts. A circular threading hole 7 is opened through the threading platform 6, and the threading hole 7 is connected to the threading channel 4 on the wave plate 3.
[0036] During specific use, the optical fiber is passed through the threading hole 7 of one of the threading platforms 6, and the optical fiber extends into the entrance of the threading channel 4 of the first wave plate 3 through the threading hole 7. Then the staff passes the optical fiber from the threading channel 4 of the wave plate 3 into the wire storage channel 5 of the wave plate 3. After the optical fiber is wound a certain number of times in the wire storage channel 5, it extends out from the exit of the threading channel 4 of the wave plate 3 and continues to be passed into the threading channel 4 of the next wave plate 3. The above steps are repeated until the optical fiber extends out from the threading hole 7 on another threading platform 6.
[0037] In this arrangement, the wave plate 3 is rotatably installed between two adjacent support platforms 2. When the polarization direction of the optical fiber needs to be adjusted, the wave plate 3 is rotated to change the angle of optical fiber transmission, which is very convenient and can effectively improve the convenience and flexibility of the control device for adjusting the polarization direction of light. At the same time, there are multiple wave plates 3, and these wave plates 3 can have a combination of multiple rotation angles, which is conducive to improving the diversity of the control device for adjusting the polarization direction of the optical fiber.
[0038] Specifically, refer to Figure 1 and Figure 2 The support platform 2 is provided with a socket 8, and the left and right ends of the bottom of the wave plate 3 are integrally formed with a rotating shaft 9, which is rotatably inserted into the corresponding socket 8. The rotating shaft 9 and the socket 8 are used to realize the rotation connection between the wave plate 3 and the support platform 2.
[0039] At the same time, refer to Figure 1 and Figure 2 A long strip-shaped observation port 16 is provided on the top of the support platform 2 along its length direction. The staff can check the installation status of the rotating shaft 9 in the support platform 2 at any time through the observation port 16, which is more convenient to use.
[0040] Reference Figure 3 The threading platform 6 includes a first block 61 and a second block 62, wherein the first block 61 is disposed above the second block 62. A clamping block 10 is integrally formed at the bottom of the first block 61 toward the direction close to the second block 62, and a clamping groove 11 is recessed at the top of the second block 62 toward the direction away from the first block 61. Specifically, when installing the threading platform 6, the clamping block 10 is clamped into the corresponding clamping groove 11, which is conducive to ensuring the stability of the installation between the first block 61 and the second block 62.
[0041] A semicircular groove is provided on the block 10 , and a semicircular groove is also provided on the groove wall of the slot 11 . When the block 10 is connected to the corresponding slot 11 , the two semicircular grooves are connected together to form a circular threading hole 7 .
[0042] At the same time, refer to Figure 1 and Figure 3 After the first block 61 and the second block 62 are connected, a first fastener 12 is inserted into the top of the first block 61, and the first fastener 12 passes through the first block 61 and is fastened to the second block 62. In this embodiment, two first fasteners 12 are provided, and the first fasteners 12 are used to further enhance the stability of the connection between the first block 61 and the second block 62.
[0043] Further, refer to Figure 1 and Figure 2 A dust cover 13 is provided on one side of the wave plate 3 where the wire storage channel 5 is provided. After the optical fiber is installed in the wire storage channel 5 of the wave plate 3, the dust cover 13 is used to cover the wire storage channel 5 on the wave plate 3, thereby effectively preventing dust from entering the wave plate 3 and affecting the optical fiber.
[0044] Specifically, refer to Figure 1 and Figure 2 A second fastener 14 is inserted between the dust cover 13 and the wave plate 3. The second fastener 14 passes through the dust cover 13 and is fastened to the wave plate 3. The dust cover 13 is fastened to the wave plate 3 by the second fastener 14, which effectively ensures the stability of the connection between the dust cover 13 and the wave plate 3.
[0045] Further, refer to Figure 1 and Figure 2The dust cover 13 and the back of the wave plate 3 are engraved with anti-skid patterns 15. When the staff member moves the wave plate 3 to rotate, the anti-skid patterns 15 can effectively increase the friction between the staff member and the wave plate 3, thereby making it more convenient for the staff member to move the wave plate 3 to rotate.
[0046] The implementation principle of an optical fiber polarization control device in the embodiment of the present application is:
[0047] During specific use, the optical fiber is passed through the threading hole 7 of one of the threading platforms 6, and the optical fiber extends into the entrance of the threading channel 4 of the first wave plate 3 through the threading hole 7. Then the staff passes the optical fiber from the threading channel 4 of the wave plate 3 into the wire storage channel 5 of the wave plate 3. After the optical fiber is wound a certain number of times in the wire storage channel 5, it extends out from the exit of the threading channel 4 of the wave plate 3 and continues to be passed into the threading channel 4 of the next wave plate 3. The above steps are repeated until the optical fiber extends out from the threading hole 7 on another threading platform 6.
[0048] In this arrangement, the wave plate 3 is rotatably installed between two adjacent support platforms 2. When the polarization direction of the optical fiber needs to be adjusted, the wave plate 3 is rotated to change the angle of optical fiber transmission, which is very convenient and can effectively improve the convenience and flexibility of the control device for adjusting the polarization direction of light. At the same time, there are multiple wave plates 3, and these wave plates 3 can have a combination of multiple rotation angles, which is conducive to improving the diversity of the control device for adjusting the polarization direction of the optical fiber.
[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
