Description

Technical Field

[0001] This invention relates to the field of optical communication technology, and in particular to a multi-core fiber optic connector angle adjustment system and its usage method. Background Technology

[0002] Unlike conventional optical fibers, multi-core optical fibers share a single cladding, resulting in a non-centrosymmetric shape. Therefore, axis alignment is required when fabricating multi-core optical fiber connectors. To form high-density connectors, multi-core optical fibers need to be threaded into multi-hole ferrules. Due to limited space and interference between fibers, axis alignment is more difficult. Therefore, a system for axis alignment of multi-hole optical fibers needs to be developed and designed.

[0003] Existing multi-port fiber optic alignment systems, such as a polarization-maintaining MT (application number 202322990369.9) system, can be adjusted according to the characteristics of polarization-maintaining fibers and the requirements for fixed-axis adjustment. However, when adjusting the alignment of multi-port fibers, multiple fibers are set on the same plane, and the distances of each fiber from the central axis of the ferrule are inconsistent. This results in the greater torque being applied to fibers farther from the central axis during alignment, and the alignment force cannot be quickly transmitted to the connector end. As a result, after adjusting the last fiber, the previously aligned fibers change their axis again due to the force being slowly transmitted to the fiber at the connector end, requiring readjustment. This process is repeated, which is time-consuming and has an extremely low yield.

[0004] Therefore, overcoming the shortcomings of the existing technology is an urgent problem to be solved in this technical field. Summary of the Invention

[0005] The technical problem to be solved by the present invention is that in the existing multi-hole fiber optic axis adjustment system, the force of axis adjustment cannot be quickly transmitted to the connector end due to the large torque of the fiber during axis adjustment.

[0006] The present invention adopts the following technical solution: In a first aspect, the present invention provides a multi-core fiber optic connector angle adjustment system, including an adjustment table 1, a ferrule fixing table 2 and a visual monitoring unit 3; The circumference of the adjusting platform 1 is provided with a plurality of optical fiber positioning components 10, and the ferrule fixing platform 2 is used to fix the ferrule component 20; wherein, the adjusting platform 1 and the ferrule fixing platform 2 are coaxially arranged so that the torque of each optical fiber 6 during adjusting tends to be consistent. One end of each optical fiber 6 is movably disposed within the ferrule 20, and the other end of each optical fiber 6 is detachably fixed within the corresponding optical fiber positioning component 10. The visual monitoring unit 3 is used to acquire real-time images of the end face of the optical fiber 6 so as to rotate the optical axis of each optical fiber 6 to a preset angle based on the real-time images.

[0007] Furthermore, each of the fiber optic positioning elements 10 is inclined at a preset angle toward the central axis of the adjusting table 1, so as to be arranged in a conical shape.

[0008] Furthermore, a plurality of fastening rings 11 are arranged around the adjusting table 1, and the fastening rings 11 correspond one-to-one with the optical fiber positioning component 10, for fixing the optical fiber positioning component 10 on the adjusting table 1.

[0009] Furthermore, one end of the fiber optic positioning component 10 protrudes from the surface of the fastening ring 11, and one end of the fiber optic positioning component 10 is engaged with an adjusting wrench 100 for rotating the fiber optic positioning component 10. The upper surface of the other end of the optical fiber positioning component 10 is provided with a groove 101, which is used to accommodate the optical fiber 6.

[0010] Furthermore, the visual monitoring unit 3 includes a camera 30 and a computer 31. The camera 30 is used to monitor the end face of the optical fiber 6 in real time and transmit the image information of the end face to the computer 31. The computer 31 is used to process image information and obtain the real-time angle of the optical axis for further adjustment.

[0011] Furthermore, the camera 30 is mounted on a three-dimensional debugging platform 300, which is used to adjust the relative position of the camera 30 and the optical fiber 6 to obtain real-time images of the end face of each optical fiber 6.

[0012] Furthermore, the shaft adjusting platform 1 is fixed at the upper end of the fixed platform 12, and the fixed platform 12, the insert fixing platform 2 and the visual monitoring unit 3 are detachably fixed on the vibration isolation plate 4. The relative distance between the fixed platform 12 and the insert fixing platform 2 is adjustable.

[0013] Furthermore, the ferrule fixing platform 2 is provided with a clamping member 21, which is used to fix the ferrule 20 on the ferrule fixing platform 2.

[0014] Furthermore, it also includes a curing component 5, which is used to pre-fix the optical fiber 6 and the ferrule 20 after the axis adjustment is completed.

[0015] Secondly, the present invention provides a method of using a multi-core fiber optic connector angle adjustment system, the method comprising: The ferrule 20 is clamped on the ferrule fixing platform 2, and one end of the optical fiber 6 is inserted into the ferrule hole 22 of the ferrule 20, so that the optical fiber 6 protrudes from the end face of the ferrule 20 by a predetermined length. The other end of the optical fiber 6 is passed through the optical fiber positioning member 10, and the optical fibers 6 are fixed one by one on the optical fiber positioning member 10, so that the optical fibers 6 are arranged in a conical shape. The angle difference between the optical axis and the horizontal direction is obtained by the visual monitoring unit 3. Rotate the fiber positioning component 10 according to the angle difference between the optical axis and the horizontal direction, and adjust all the fiber positioning components 10 in sequence until the optical axis of all the optical fibers 6 is rotated to the preset angle, and pre-cur the optical fibers 6 and the ferrule 20 after the axis adjustment is completed.

[0016] The beneficial effects of the present invention are as follows: by setting the axis adjustment platform and the ferrule fixing platform coaxially and arranging multiple optical fiber positioning components around the axis adjustment platform, the torque of all optical fibers tends to be consistent and the torque value is small during axis adjustment, and the axis adjustment force can be quickly transmitted to the connector end. The angle adjustment system is simple to operate, saves time and has a high yield.

[0017] Furthermore, by tilting the fiber positioning component at a preset angle, the fiber is distributed in a conical shape. The tilting increases the bending radius of the fiber, further improving the efficiency of force transmission from the axis adjustment to the connector end. Attached Figure Description

[0025] Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0026] Example 1: With the continuous rise of Internet applications and the booming development of services such as cloud computing and big data, the bandwidth of fiber optic communication networks continues to grow at a rate of 20% to 40% annually. Fiber optic communication is a communication method that uses light waves as the information carrier and optical fibers as the transmission medium. In the field of optical communication technology, it typically involves devices such as connectors, optical modules, and adapters.

[0027] Due to the nonlinear effects of optical fibers, optical fiber communication systems based on traditional single-mode fibers are approaching the Shannon limit. Therefore, there is an urgent need to research high-capacity, high-spectral-efficiency, and commercially viable high-speed optical fiber transmission solutions. Space division multiplexing (SDM) technology, represented by multi-core and few-mode fibers, is considered the second technological revolution in optical fiber transmission technology after wavelength division multiplexing (WDM).

[0028] Space division multiplexing (SDM) refers to a multiplexing technique that establishes multiple partitioned spatial data channels, which can increase system capacity and spectral efficiency several times over, making it one of the key technologies for building future optical networks. Research based on multi-core optical fibers is increasing, which in turn creates new requirements and impacts on the design of supporting devices, equipment, and transmission systems. To form high-density connectors, multi-core optical fibers need to be inserted into multi-hole ferrules. Due to limited space, interference exists between the fibers, making axis alignment more difficult. Therefore, it is necessary to develop and design a system for axis alignment of multi-hole optical fibers.

[0029] See Figures 1-3 Embodiment 1 of the present invention provides a multi-core fiber optic connector angle adjustment system, including an adjustment platform 1, a ferrule fixing platform 2, and a visual monitoring unit 3; the adjustment platform 1 is provided with a plurality of fiber optic positioning elements 10 around its periphery, and the ferrule fixing platform 2 is used to fix the ferrule 20; wherein, the adjustment platform 1 and the ferrule fixing platform 2 are coaxially arranged so that the torque of each fiber 6 during adjustment tends to be consistent; one end of each fiber 6 is movably disposed in the ferrule 20, and the other end of each fiber 6 is detachably fixed in the corresponding fiber optic positioning element 10; the visual monitoring unit 3 is used to acquire real-time images of the end face of the fiber 6 so as to rotate the optical axis of each fiber 6 to a preset angle according to the real-time images.

[0030] In existing multi-port fiber optic alignment systems, the distances of each fiber 6 from the central axis of the ferrule are inconsistent, resulting in a greater torque on the fiber 6 farther from the central axis during alignment. This prevents the alignment force from being quickly transmitted to the connector end. In this embodiment, by coaxially arranging the alignment platform and the ferrule fixing platform and surrounding the alignment platform with multiple fiber positioning components, the torque of all fibers 6 during alignment tends to be consistent and the torque value is small. Moreover, the alignment force can be quickly transmitted to the connector end. The angle adjustment system is simple to operate, saves time, and has a high yield.

[0031] In one embodiment, the adjusting platform 1 and the ferrule fixing platform 2 are arranged opposite to each other, the central axis of the adjusting platform 1 and the central axis of the ferrule 20 are coaxially arranged, the fiber positioning component 10 is arranged around the adjusting platform 1, and the adjusting platform 1 can be a thin cylinder or a frustum, wherein the end of the frustum with a smaller cross section is close to the ferrule fixing component.

[0032] In one embodiment, see below. Figure 2 The ferrule 20 is provided with a plurality of ferrule holes 22. One end of the optical fiber 6 is movably disposed in the ferrule hole 22, and the end face of the optical fiber 6 protrudes from the surface of the ferrule 20 by a preset distance, the preset distance being 3mm to 8mm. In actual use scenarios, the optical fiber 6 can be a polarization-maintaining optical fiber or a multi-core optical fiber.

[0033] In one embodiment, the visual monitoring unit 3 is disposed on the other side of the ferrule fixing platform 2 and is used to monitor the real-time image of the end face. The visual monitoring unit 3 can display the angle between the actual optical axis of the optical fiber 6 to be adjusted and the horizontal direction for further adjustment.

[0034] Further reading Figure 2 The ferrule fixing platform 2 is provided with a clamping member 21, which is used to fix the ferrule 20 on the ferrule fixing platform 2. In one embodiment, the clamping member 21 includes a fixing block 210 and a locking block 211. The ferrule 20 can be fixed by adjusting the distance between the fixing block 210 and the locking block 211. Specifically, the ferrule fixing platform 2 is also provided with a baffle 212, which is threaded. The other end of the locking block 211 abuts against a screw. The baffle 212 and the screw are fixed by a threaded connection. By adjusting the engagement depth of the baffle 212 and the screw, the length of one end of the screw protruding from the baffle 212 can be adjusted to adjust the distance between the locking block 211 and the fixing block 210.

[0035] In one embodiment, all the fiber optic positioning elements 10 are arranged parallel to the horizontal plane, such that the distance between all the fiber optic positioning elements 10 and the ferrule 20 in the vertical plane tends to be consistent, that is, the torque of all the fibers 6 during axis adjustment tends to be consistent. (See also...) Figure 4 The horizontal arrangement of the fiber optic positioning component 10 results in two bending radii for the fiber optic cable 6 during axis adjustment, which is not conducive to the rapid transmission of the adjustment force to the connector end. Furthermore, the horizontal arrangement of the fiber optic positioning component 10 makes the angle adjustment system larger in size.

[0036] To improve space utilization, see Figure 3 and Figure 5 In a preferred embodiment, each of the fiber optic positioning elements 10 is inclined at a preset angle toward the central axis of the adjusting table 1, so as to be arranged in a conical shape. Figure 3 AA is the central axis of the adjusting table 1.

[0037] In one embodiment, taking an optical fiber positioning component 10 as an example, the optical fiber positioning component 10 is provided with a groove 101 for accommodating the optical fiber 6. In practical applications, the optical fiber 6 can be detachably fixed in the groove 101 using a magnetic suction plate or tape. The optical fiber 6 is tilted at a preset angle to form a conical shape. The preset angle should minimize the torque of the optical fiber 6 during axis adjustment. The intersection of all the extended points of the optical fibers 6 should fall on the central axis of the axis adjustment table 1. In practical applications, the preset angle should be as small as possible. The angle between the optical fiber positioning component 10 and the horizontal plane is in the range of 0 degrees to 45 degrees (excluding 0 degrees). The preset angle can be 45 degrees or any value within the aforementioned range.

[0038] Furthermore, by tilting the fiber positioning component 10 at a preset angle to make the fiber 6 tapered, the bending radius of the fiber 6 can be increased while maintaining space utilization. The torque required for adjustment is also less than that required for other applications. Figure 4 The method shown is smaller, further improving the efficiency of force transmission to the connector end during shaft adjustment. It should be noted that when the optical fiber 6 is in a straight state, the bending radius is largest, and the torque required for adjustment is smallest. However, when the optical fiber 6 is placed straight, the problems described in the background art exist. This embodiment combines the advantages of consistent torque and minimizing the increase in torque.

[0039] To ensure that the fiber optic positioning component 10 is fixed at a preset angle on the adjusting table 1, refer to... Figure 3 and Figure 6 A plurality of fastening rings 11 are arranged around the adjusting table 1, and the fastening rings 11 correspond one-to-one with the optical fiber positioning component 10, and are used to fix the optical fiber positioning component 10 on the adjusting table 1.

[0040] In one embodiment, a plurality of fastening rings 11 are arranged in a ring, and the number of fastening rings 11 and the number of optical fiber positioning components 10 are the same. Each optical fiber positioning component 10 is fixed on the adjusting table 1 by a corresponding fastening ring 11. Specifically, the fastening ring 11 fixes the optical fiber positioning component 10 at a preset angle, and the optical fiber positioning component 10 and the fastening ring 11 can be fixed together by threaded connection.

[0041] To rotate the fiber positioning element 10 to adjust the axis of the fiber 6, please refer to [link / reference needed]. Figure 6 One end of the fiber positioning component 10 protrudes from the surface of the fastening ring 11, and one end of the fiber positioning component 10 is engaged with an adjusting wrench 100 for rotating the fiber positioning component 10; the upper surface of the other end of the fiber positioning component 10 is provided with a groove 101 for accommodating the fiber 6.

[0042] Specifically, the fiber optic positioning component 10 includes a rotating wheel 102 and a rotor 103 fixed together by a threaded connection. In one embodiment, one end of the rotor 103 is provided with an annular component 104. The fastening ring 11 is used to accommodate and fix the annular component 104. One end of the fastening ring 11 extends to a connecting portion 111. The connecting portion 111 is fixed to the adjusting table 1 by bolts. The connecting portion 111 is provided with a through groove 112. The through groove 112 extends to one end of the fastening ring. By reducing the width of the through groove 112, a radial force can be applied to the annular component 104 to fix the fiber optic positioning component 10 to the adjusting table 1.

[0043] To ensure a secure fixation effect, in a preferred embodiment, a damping ring 110 is fitted inside the fastening ring 11. The damping ring 110 is used to increase the friction between the inner wall of the fastening ring 11 and the annular member 104. The damping ring 110 is made of elastic material and will undergo elastic deformation when squeezed by the fastening ring 11 and the annular member 104, generating a rebound force and applying a radial force to the annular member 104, thereby improving the fixation effect on the optical fiber positioning member 10.

[0044] In one embodiment, the upper surface of the rotor 103 is provided with a groove 101, which is used to accommodate and fix the optical fiber 6. In actual use, the groove 101 can be a V-shaped groove or a U-shaped groove, etc., and the specific shape of the groove 101 is determined according to the actual situation.

[0045] In one embodiment, the rotating wheel 102 is fixed to the annular member 104 by a threaded connection, the rotating wheel 102 protrudes from the fastening ring 11, and the optical fiber 6 can be rotated by rotating the rotating wheel 102.

[0046] To facilitate the rotation of the optical fiber positioning component 10, in a preferred embodiment, an adjusting wrench 100 is engaged on the rotating wheel 102. Specifically, the adjusting wrench 100 is engaged on the rotating wheel 102 corresponding to the optical fiber 6 to be adjusted. By rotating the adjusting wrench 100, the optical fiber 6 can be adjusted. In actual use, the number of adjusting wrenches 100 can be set to one or more. Since all the rotating wheels 102 have the same shape, the adjusting wrench 100 can be adapted to all the rotating wheels 102. In a preferred embodiment, the number of adjusting wrenches 100 is set to one to reduce the size of the angle adjustment system.

[0047] In one embodiment, the optical fiber positioning member 10 is provided with an axially accommodating space for the other end of the optical fiber 6 to pass through, and to protect the optical fiber 6 from bending or even damage. The accommodating space and the groove 101 are located on the same axis to increase the bending radius of the optical fiber 6 and further ensure that the force of the axis adjustment can be quickly transmitted to the connector end.

[0048] In a preferred embodiment, for ease of operation, openings (not shown in the figure) are provided at corresponding positions on the fastening ring 11, the rotating wheel 102 and the adjusting wrench 100. The optical fiber 6 can be directly placed into the receiving space through the openings, which improves the convenience of operation.

[0049] To obtain the difference between the real-time angle of the optical axis and the preset angle, refer to... Figure 7 The visual monitoring unit 3 includes a camera 30 and a computer 31. The camera 30 is used to monitor the end face of the optical fiber 6 in real time and transmit the image information of the end face to the computer 31. The computer 31 is used to process the image information and obtain the real-time angle of the optical axis for further adjustment.

[0050] In one embodiment, the computer 31 is connected to the camera 30 via a wire, enabling the computer 31 to receive image information. The computer 31 is equipped with software for image processing, which can determine the angle between the optical axis of the end face of the optical fiber 6 and the horizontal direction, and display the image information on the display screen of the computer 31. The optical axis is rotated to a preset angle by rotating the axis adjustment wrench 100 through the real-time image.

[0051] To adjust the clarity of the image information, please refer to [link / reference needed]. Figure 7 The camera 30 is mounted on a three-dimensional debugging platform 300, which is used to adjust the relative position of the camera 30 and the optical fiber 6 to obtain real-time images of the end face of each optical fiber 6.

[0052] In one embodiment, the three-dimensional adjustment platform 300 can adjust the three-axis position of the camera 30 so that the clarity of the real-time image acquired by the camera 30 meets the requirements. In actual use, after the clarity of the camera 30 is adjusted, the position of the camera 30 is fixed to remain unchanged in order to improve the accuracy of axis adjustment.

[0053] In a preferred embodiment, the ferrule fixing stage 2 is mounted on a three-axis adjustment stage 23. The clarity of the real-time image can be further adjusted according to the different lengths of the optical fiber 6 protruding from the ferrule 20, so as to ensure the accuracy of axis adjustment.

[0054] To adapt to different types of ferrule 20, please refer to [link / reference needed]. Figure 7 The adjusting platform 1 is fixed to the upper end of the fixed platform 12 by bolts. The fixed platform 12, the insert fixing platform 2, and the visual monitoring unit 3 are detachably fixed to the vibration isolation plate 4. The relative distance between the fixed platform 12 and the insert fixing platform 2 is adjustable. In one embodiment, the adjusting platform 1 is fixed to the upper end of the fixed platform 12 by a threaded connection. The vibration isolation plate 4 is provided with multiple fixing holes. By fixing the fixed platform 12, the insert fixing platform 2, and the visual monitoring unit 3 to different fixing holes, the positions of the three on the vibration isolation plate 4 can be adjusted. The fixed platform 12, the insert fixing platform 2, and the visual monitoring unit 3 can be connected to the fixing holes by threads. The vibration isolation plate 4 is used to improve the vibration resistance of the angle adjustment system to improve the accuracy of the adjustment.

[0055] In a preferred embodiment, a lighting lamp is also fixed on the vibration isolation plate 4. The lighting lamp is used to increase the brightness difference of the end face in order to further confirm the difference between the real-time angle of the optical axis and the preset angle.

[0056] To ensure that the optical axis of the optical fiber 6 remains unchanged after the axis adjustment is completed, please refer to [the relevant documentation]. Figure 7 The system also includes a curing component 5, which is used to pre-fix the optical fiber 6 and the ferrule 20 after they have been aligned. In one embodiment, the curing component 5 includes a UV lamp and UV adhesive. The UV adhesive is applied to the ferrule hole 22 to fix the optical fiber 6 and the ferrule 20 together. Specifically, installing the UV lamp does not require moving the aligned optical fiber 6, thus avoiding axial changes caused by moving the optical fiber 6. The alignment of the optical fiber 6 can be completed directly by the UV lamp, eliminating the need for turnover during the alignment process, making the operation simple, quick, and efficient.

[0057] Example 2: See Figure 8 Embodiment 2 of the present invention provides a method for using a multi-core fiber optic connector angle adjustment system. Using the multi-core fiber optic connector angle adjustment system described in Embodiment 1 specifically includes the following steps: Step 101: Clamp the ferrule 20 on the ferrule fixing platform 2, and insert one end of the optical fiber 6 into the ferrule hole 22 of the ferrule 20, so that the optical fiber 6 protrudes from the end face of the ferrule 20 by a predetermined length.

[0058] In one embodiment, the fixing platform 12 and the triaxial adjustment platform 23 are fixed to the vibration isolation plate 4 by a threaded connection at a preset distance, and the ferrule fixing platform 2 is fixed to the triaxial adjustment platform 23. The ferrule 20 is clamped on the ferrule fixing platform 2 by adjusting the distance between the fixing block 210 and the locking block 211. In practical applications, taking a 12-hole MT ferrule 20 and an MCF4 core optical fiber 6 as an example, after arranging 12 MCF4 core optical fibers 6 side by side, the coating layer is stripped, and the end faces of the optical fibers 6 are cut together using a fiber cleaver before being inserted into the 12-hole MT ferrule 20. The preset distance by which the end face of the optical fiber 6 protrudes from the surface of the ferrule 20 can be set to 3mm~8mm.

[0059] Step 102: Pass the other end of the optical fiber 6 through the optical fiber positioning member 10, and fix the optical fibers 6 one by one on the optical fiber positioning member 10 so that the optical fibers 6 are arranged in a conical shape. The angle difference between the optical axis and the horizontal direction is obtained by the visual monitoring unit 3.

[0060] In one embodiment, the other end of the optical fiber 6 is passed through the optical fiber positioning member 10 and the optical fiber 6 is accommodated in the groove 101. The optical fiber 6 is fixed in the groove 101 by a magnetic suction plate or tape, so that the optical fibers 6 are tapered and the torque and bending radius of all the optical fibers 6 tend to be consistent when adjusting the axis.

[0061] The visual monitoring unit 3 is fixed to the vibration isolation plate 4 by a threaded connection. Specifically, the camera 30 is fixed to the three-dimensional debugging platform 300 by a threaded connection. The three-dimensional debugging platform 300 is fixed to the vibration isolation plate 4 by a threaded connection according to the preset debugging position. Furthermore, the three-dimensional debugging platform 300 is adjusted so that the camera 30 can focus on the end face of the optical fiber 6 to obtain a real-time image of the end face, and the real-time image is transmitted to the computer 31 to obtain the difference between the real-time angle of the optical axis of the end face and the preset angle for further adjustment.

[0062] Step 103: Rotate the fiber positioning component 10 according to the angle difference between the optical axis and the horizontal direction, and adjust all the fiber positioning components 10 in sequence until the optical axis of all the optical fibers 6 is rotated to the preset angle, and pre-cur the optical fibers 6 and the ferrule 20 after the axis adjustment is completed.

[0063] In one embodiment, the adjusting wrench 100 is engaged with one end of the fiber positioning member 10 corresponding to the fiber optic cable 6 to be adjusted. The adjusting wrench 100 is rotated according to the angular difference between the optical axis and the horizontal direction to change the angle of the optical axis to a preset angle. After all the fibers 6 have been adjusted, UV adhesive is applied to the ferrule 22, and the UV lamp is turned on to cure the UV adhesive, thereby fixing the fiber optic cable 6 in the ferrule 20.

[0064] By tilting the fiber positioning component 10 at a preset angle, the optical fibers 6 can be arranged in a conical shape. This design makes the torque of each optical fiber 6 more consistent and smaller during the axis adjustment process, while increasing the bending radius of the optical fibers 6, which is beneficial for the rapid transmission of the axis adjustment force to the connector end. This method is simple to operate, helps to save assembly time and improve the yield rate.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
