[0023] The fiber flange is configured to be connected to the fiber assembly to fix the fiber assembly. At present, after light is coupled into the polarization-maintaining fiber, at least one half-wave plate is required to rotate the polarization direction of the incident light so that the polarization direction of the incident light coincides with the fast axis of the polarization-maintaining fiber; or after light is emitted from the polarization-maintaining fiber, a half-wave plate is required to adjust the polarization direction of the emitted light. Therefore, the existing fiber flange needs to be equipped with an additional half-wave plate to adjust the polarization direction of the light, making it inconvenient to adjust the polarization direction of the light.

[0024] Please combine Figures 1 to 4 , the optical fiber flange 10 provided in the embodiment of the present disclosure is now described. The optical fiber flange 10 includes a fixing member 11 and a connection port 12. Among them, the fixing member 11 can connect the entire optical fiber flange 10 to other devices, so as to facilitate the connection of other devices with optical fibers. In the embodiment of the present disclosure, the fixing member 11 is compatible with a cage system or a coaxial system and has a plate-like structure. The fixing member 11 is provided with a plurality of through holes 100 around its axial direction, and the through holes 100 penetrate the fixing member 11 along the axial direction of the fixing member 11. The through holes 100 are arranged for a connecting rod to pass through, so that the connecting rod can connect a plurality of fixing members 11. A plurality of fastening holes 200 are arranged on the circumferential outer side of the fixing member 11, and the plurality of fastening holes 200 are connected to the plurality of through holes 100 in a one-to-one correspondence to fasten the fixing member 11 and the connecting rod. The optical fiber assembly 20 includes a polarization-maintaining optical fiber 21 and an optical fiber connector 22 arranged at the end of the polarization-maintaining optical fiber 21.

[0025] The connection port 12 is configured to be fixedly connected to the optical fiber connector 22, so that the optical fiber connector 22 is coaxially arranged with the connection port 12. The connection port 12 is rotatably connected to the fixing member 11 and can rotate relative to the fixing member 11 along the axial direction of the connection port 12.

[0026] The disclosed embodiment includes a fixing member 11 and a connection port 12. Among them, the fixing member 11 can connect the entire fiber flange 10 to other devices, so as to facilitate the connection of other devices to the optical fiber. The connection port 12 is configured to be fixedly connected to the optical fiber connector 22, so that the optical fiber connector 22 is coaxially arranged with the connection port 12, and the connection port 12 is rotationally connected to the fixing member 11 and can rotate relative to the fixing member 11 along the axial direction of the connection port 12. In this way, by rotating the connection port 12 relative to the fixing member 11, the fast axis of the polarization-maintaining optical fiber 21 can be rotated, the fast axis of the polarization-maintaining optical fiber 21 and the polarization direction of the incident light can be aligned and overlapped, and the polarization direction of the outgoing light can be adjusted, thereby facilitating the adjustment of the polarization direction of the light.

[0027] In the exemplary embodiment, please combine Figures 2 to 6 , the connection port 12 includes a circumferential wall 121 and a bottom wall 122. The circumferential wall 121 is coaxially arranged with the axial direction of the connection port 12, and the bottom wall 122 is arranged at one end of the circumferential wall 121 along the axial direction of the connection port 12, and the end of the circumferential wall 121 away from the bottom wall 122 has a mouth 1211, and the mouth 1211 is arranged to be plugged with the optical fiber connector 22. In this way, the optical fiber connector 22 can be conveniently connected to the connection port 12 by plugging. It can be understood that in other embodiments, the optical fiber connector 22 can also be threadedly connected to the circumferential wall 121 to fix the optical fiber connector 22 to the connection port 12.

[0028] The provision of the bottom wall 122 can enhance the structural strength of the circumferential wall 121 and prevent the circumferential wall 121 from being plastically deformed when connected to the optical fiber connector 22 .

[0029] A key groove 300 is provided on the circumferential outer side of the circumferential wall 121. The key groove 300 penetrates the circumferential wall 121 in the radial direction of the circumferential wall 121. The key groove 300 is arranged to be positioned with the optical fiber connector 22 to determine the direction of the polarization-maintaining optical fiber 21. The optical fiber connector 22 may be provided with a positioning protrusion 221, so as to cooperate with the key groove 300 to fix the position of the optical fiber connector 22 and the connection port 12, and prevent the optical fiber connector 22 from moving relative to the connection port 12 during the rotation of the connection port 12 relative to the fixing member 11. The provision of the key groove 300 can improve the elastic deformation ability of the circumferential wall 121, can elastically wrap the optical fiber connector 22, and improve the connection stability between the optical fiber connector 22 and the connection port 12. The positioning protrusion 221 can be accommodated in the key groove 300. Under the restriction of the key groove 300 wall provided along the circumference of the circumferential wall 121, the optical fiber connector 22 can be prevented from rotating relative to the connection port 12. In the disclosed embodiment, the key slot 300 extends to the mouth 1211, so that the mouth 1211 can avoid the positioning protrusion 221. The direction of the polarization-maintaining optical fiber 21 can be the fast axis or the slow axis. That is, the key slot 300 is positioned with the optical fiber connector 22 to determine the position of the fast axis or the position of the slow axis. The setting of the key slot 300 can also serve as a prompt for whether the connection port 12 is rotated and the direction of rotation.

[0030] The bottom wall 122 is provided with a ferrule groove 400 , which is configured to match the optical fiber ceramic ferrule 23 to position the polarization-maintaining optical fiber 21 .

[0031] In the exemplary embodiment, please combine Figures 1 to 6 The optical fiber flange 10 further includes a rotating member 13. The bottom wall 122 is disposed on the rotating member 13. The connection port 12 is rotationally connected to the fixing member 11 through the rotating member 13. Thus, the connection area between the connection port 12 and the fixing member 11 can be increased by disposing the rotating member 13, the arrangement of the rotating matching structure is facilitated, and the rotation stability between the connection port 12 and the fixing member 11 is improved.

[0032] In the exemplary embodiment, please combine Figure 2 , Figure 3 , Figure 5 and Figure 6The rotating member 13 includes a body 131 and an annular wall 132 disposed on the body 131. The fixed member 11 has an inner wall 111 that can enclose a through hole 500. The annular wall 132 and the inner wall 111 are coaxially disposed. The annular wall 132 can fit with the inner wall 111 and can rotate along the inner wall 111 around the axial direction of the inner wall 111. In this way, the connection between the connecting surface of the rotating member 13 and the fixed member 11 can be improved by the arrangement of the annular wall 132 and the inner wall 111, and the stability of the rotation of the rotating member 13 relative to the fixed member 11 can be improved, thereby improving the stability of the rotation of the connection port 12 relative to the fixed member 11. In the embodiment of the present disclosure, the annular wall 132 is vertically disposed on one side of the body 131, so that the annular wall 132 is a hollow structure with a certain elastic deformation ability. At this time, the annular wall 132 and the inner wall 111 can be set to an interference fit, and the elastic deformation ability of the annular wall 132 can be used to facilitate the rotation of the annular wall 132 relative to the inner wall 111. In addition, the elastic deformation ability of the annular wall 132 can also be used to fix the position between the annular wall 132 and the inner wall 111 after the external force is removed, thereby keeping the polarization direction of the incident light / outgoing light fixed.

[0033] In the disclosed embodiment, the axial direction of the connection port 12 is tilted relative to the axial direction of the annular wall 132 , so that the connection port 12 can be fixedly connected to the FC / APC optical fiber connector.

[0034] It can be understood that in other embodiments, the connection port 12 can also be coaxially arranged with the annular wall 132, so that the connection port 12 can be fixedly connected to the FC / PC optical fiber connector.

[0035] In the exemplary embodiment, please combine Figure 3 and Figure 5 The annular wall 132 has a plurality of notches. The plurality of notches are arranged around the axial direction of the annular wall 132. The notches are provided with elastic arms 1321. One end of the elastic arm 1321 is connected to the annular wall 132 or the body 131, and the other end of the elastic arm 1321 is provided with a protrusion 1322. In the disclosed embodiment, one end of the elastic arm 1321 is connected to the body 131.

[0036] The protrusion 1322 extends from the elastic arm 1321 to one side of the inner wall 111, and the fixing member 11 is located between the body 131 and the protrusion 1322. During the installation of the annular wall 132 into the through hole 500, the protrusion 1322 can abut against the inner wall 111, driving the elastic arm 1321 to undergo elastic deformation, so as to facilitate the protrusion 1322 to cross the restriction of the inner wall 111 until the annular wall 132 is installed in the through hole 500. At this time, the protrusion 1322 is separated from the inner wall 111, the elastic arm 1321 returns to its original state, and resets the protrusion 1322, so that the fixing member 11 is located between the body 131 and the protrusion 1322, so as to limit the rotation member 13 from moving relative to the fixing member 11 along its axial direction.

[0037] In the exemplary embodiment, please combine Figure 3 , Figure 5 and Figure 6 The fixing member 11 is provided with an annular groove 600, which is arranged in the axial direction of the inner wall 111. The annular groove 600 is connected with the through hole 500 to form a stepped groove, and the protrusion 1322 is received in the annular groove 600. In this way, the protrusion 1322 can be received by the setting of the annular groove 600, so as to prevent the protrusion 1322 from scratching other equipment during the rotation of the rotating member 13 relative to the fixing member 11.

[0038] In the exemplary embodiment, please combine Figure 3 and Figure 5 The side of the protrusion 1322 facing away from the elastic arm 1321 has an inclined surface 1323. During the installation of the annular wall 132 into the through hole 500, the setting of the inclined surface 1323 can facilitate the protrusion 1322 to contact with the fixing member 11 and slide into the through hole 500 along the fixing member 11, gradually increasing the elastic deformation of the elastic arm 1321, so that the protrusion 1322 can slide smoothly into the through hole 500.

[0039] The fixing member 11 is located between the body 131 and the raised portion 1322, and the body 131 and the raised portion 1322 can clamp the fixing member 11. The fixing member 11 can also be spaced apart from at least one of the body 131 and the raised portion 1322. Figure 5 As shown, the fixing member 11 and the body 131 are spaced apart in the axial direction of the annular wall 132, and are in contact with the protrusion 1322 in the axial direction of the annular wall 132. When the fixing member 11 and the rotating member 13 need to be separated, the body 131 can be driven to be in contact with the fixing member 11 in the axial direction of the annular wall 132. At this time, the protrusion 1322 is partially moved out of the annular groove 600, which is convenient for manually pressing the inclined surface 1323, so that the force direction of the rotating member 13 points to the body 131, which is convenient for the protrusion 1322 to cross the restriction of the inner wall 111 and re-enter the through hole 500, so as to facilitate the separation of the fixing member 11 and the rotating member 13.

[0040] In the exemplary embodiment, please combine Figure 3 , Figure 5 and Figure 6 The body 131 is provided with a protrusion 133, which is accommodated in the space surrounded by the annular wall 132 and is spaced apart from the annular wall 132 to ensure the elastic deformation capability of the annular wall 132 and the elastic arm 1321. The spacing distance between the protrusion 133 and the annular wall 132 along the radial direction of the annular wall 132 is greater than twice the size of the protrusion 1322 along the radial direction of the annular wall 132, and less than three times the size of the protrusion 1322 along the radial direction of the annular wall 132.

[0041] The main body 131 is provided with a groove 700, which extends to the protrusion 133. The connection port 12 is received in the groove 700 and connected to the protrusion 133. The connection port 12 is spaced apart from the groove wall of the groove 700 to facilitate the optical fiber connector 22 to be partially received in the groove 700 and plugged into the connection port 12.

[0042] The ferrule groove 400 passes through the protrusion 133 to increase the connection surface area between the optical fiber ceramic ferrule 23 and the optical fiber flange 10 , and further improve the stability of the positioning of the polarization-maintaining optical fiber 21 .

[0043] In the exemplary embodiment, please combine Figures 1 to 4 and Figure 6 , the circumferential outer side of the body 131 is located on the cylindrical surface, so that the rotation trajectory of the circumferential outer side of the body 131 is located on the cylindrical surface. The fixing member 11 is provided with a fitting surface 112, and the fitting surface 112 is fitted with the circumferential outer side of the body 131, so that the fitting surface 112 can provide support to the body 131 from the radial outer side of the body 131, thereby improving the stability of the rotation of the rotating member 13 relative to the fixing member 11. In addition, static friction can also be generated between the fitting surface 112 and the body 131, and after the polarization direction of the incident light / outgoing light is adjusted, the polarization direction of the incident light / outgoing light can be kept fixed. In the embodiment of the present disclosure, a plurality of slots 800 are also provided on the circumferential outer side of the body 131 to increase the static friction between the finger and the body 131, so as to facilitate driving the rotating member 13 to rotate relative to the fixing member 11.

[0044] In the exemplary embodiment, please combine Figure 1 , Figure 2 , Figure 4 and Figure 6, the body 131 has a scale surface 1311 on the side away from the fixed part 11. The fixed part 11 is provided with a fitting block 113, and the fitting surface 112 is provided on the fitting block 113. The fitting block 113 is provided with a reference portion 114 matching the scale surface 1311 on the side away from the fixed part 11. In this way, the angle of rotation of the rotating part 13 relative to the fixed part 11 can be clearly displayed through the setting of the scale surface 1311 and the reference portion 114, which is convenient for recording the rotation angle of the rotating part 13. The setting of the fitting block 113, on the one hand, can provide support for the fitting surface 112 to ensure the stability of the fitting between the fitting surface 112 and the body 131; on the other hand, it can enable the reference portion 114 to be close to the scale surface 1311 to ensure the accuracy of the rotation angle measurement.

[0045] In the exemplary embodiment, please combine Figures 1 to 3 and Figure 6 The fixing member 11 is provided with a positioning hole 900, and the optical fiber flange 10 also includes a positioning member (not shown), which is provided in the positioning hole 900 and can be positioned and connected with the annular wall 132. After the polarization direction of the incident light / outgoing light is adjusted, the positioning member and the annular wall 132 are positioned and connected to further keep the polarization direction of the incident light / outgoing light fixed. The positioning member and the fixing member 11 can form a detachable connection through threaded connection, snap-on connection or plug-in connection, and can abut against the annular wall 132, and be positioned and connected with the annular wall 132, ensuring that the annular wall 132 is not damaged by the positioning member and the relative position between the fixing member 11 is fixed. In the embodiment of the present disclosure, a groove structure 1000 is provided on the circumferential outer side of the fixing member 11, and the positioning hole 900 is provided at the bottom of the groove structure 1000 and extends to the through hole 500. The provision of the groove 700 enables the positioning member to be partially accommodated in the positioning hole 900 and partially accommodated in the groove structure 1000 after being separated from the annular wall 132, thereby preventing the positioning member from touching other devices after being separated from the annular wall 132.
