[0001] This utility model relates to the field of optical fiber testing technology, and specifically to an optical fiber connector testing device. Background Technology

[0002] Optical fiber, as a crucial carrier of information transmission, is widely used in numerous scenarios such as data centers, communication networks, and fiber-to-the-home (FTTH). To ensure the transmission performance and quality of optical fibers, testing is an essential step.

[0003] Currently, testing methods for fiber optic connectors are mainly conducted manually or semi-automatically. The specific operation involves the tester inserting the fiber optic connector into the testing equipment and then starting the test program to check the performance parameters of the fiber optic channel. A single optical cable often includes multiple fiber optic connectors. After testing all the fiber optic channels within a cable, the tester needs to manually remove the fiber optic connectors and then insert the next one for testing. This testing method, to a certain extent, meets the testing requirements for fiber optic connectors.

[0004] However, using existing testing methods, when continuously testing multiple fiber optic connectors on an optical cable, testers need to frequently plug and unplug the fiber optic connectors, resulting in a long testing time. Summary of the Invention

[0005] In view of the time-consuming nature of existing technologies, the purpose of this utility model is to provide a time-saving fiber optic connector testing device.

[0006] To solve the above problems, this utility model provides the following technical solution:

[0007] A fiber optic connector testing device includes: multiple ports, wherein the ports are used to insert fiber optic connectors at the input end of an optical cable, and the ports are capable of sending optical signals to the inserted fiber optic connectors;

[0009] The translation assembly includes multiple mounting bases, which can drive the mounting bases to move. The mounting bases are used to insert fiber optic connectors at the output end of the optical cable.

[0010] A control component is used to control the translation component to translate, thereby allowing the detection component to receive optical signals transmitted from the fiber optic connectors at different output ends.

[0011] In some embodiments, the projection of the detection component onto the translation component is located on the movement path of the plurality of mounting bases;

[0012] After the control component controls the translation component to translate, the translation component causes the mounting base to translate to the projection point of the detection component.

[0017] In some embodiments, a plurality of the mounting seats are arranged at equal intervals on the carrier.

[0018] In some embodiments, the translation assembly further includes a mounting base and a track;

[0019] The track is disposed on the fixed base, the support member is installed on the track, and the support member can move along the track;

[0020] The driving component is mounted on the fixed base, and the driving component drives the carrier to move along the track.

[0021] In some embodiments, the drive element includes a second motor and a screw;

[0022] The second motor and the screw are mounted on the fixed base, and the second motor can drive the screw to rotate;

[0023] The bearing component is provided with internal threads;

[0024] The bearing component is installed on the screw via an internal thread;

[0025] When the second motor rotates, the screw drives the carrier to move along the track.

[0029] When the port sends a signal, the signal is transmitted into the optical fiber via the first connector and the optical fiber connector.

[0030] In some embodiments, the detection component includes a detection window;

[0031] The detection window is used to receive the optical signal transmitted by the optical fiber connector at the output end.

[0032] The control component is used to analyze the optical signal to obtain the detection result.

[0033] In some embodiments, the port is provided with a signal transmitting source for transmitting test optical signals.

[0034] The beneficial effects of this utility model are: after the control component completes one test on the fiber optic connector on the mounting base of the detection component, the control component only needs to control the translation component to move the fiber optic connector on the mounting base; so that the fiber optic connector to be tested on the mounting base is moved to the detection component, without the need to repeatedly plug and unplug the fiber optic connector, thus eliminating the need to spend a lot of time on plugging and unplugging.

[0048] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0050] For ease of description of the first, second, and third directions in the embodiments of this application, the first direction is the left-right direction in the figures, the second direction is the front-back direction in the figures, and the third direction is the up-down direction in the figures. The x-axis arrow direction is referred to as the "right" direction, the y-axis arrow direction as the "up" direction, and the z-axis arrow direction as the "back" direction, but these are not the sole limitations in the actual application of this application.

[0051] like Figure 1As shown in Figures 4-6, this embodiment provides a fiber optic connector testing device 100, which includes multiple ports 130, a detection component 140, a moving component 120, and a control component 170. Ports 130 are used to insert fiber optic connectors 220 into the input end 211 of the optical cable 210, and can send optical signals to the inserted fiber optic connectors 220. The detection component 140 is used to receive the optical signals sent by the fiber optic connectors 220. The moving component 120 includes multiple mounting bases 150, which can drive the mounting bases 150 to move. The mounting bases 150 are used to insert fiber optic connectors 220 into the output end 212 of the optical cable 210. The control component 170 is used to control the movement of the moving component 120, thereby allowing the detection component 140 to receive optical signals transmitted from fiber optic connectors 220 at different output ends 212. In other words, during installation, the fiber optic connectors 220 of multiple fiber optic input terminals 211 are connected to the port 130 in sequence, and the fiber optic connectors 220 of multiple fiber optic output terminals 212 are inserted into a corresponding mounting base 150. During testing, the signal emitted through the port 130 is transmitted to the detection component 140 via the fiber optic cable 210. The detection component 140 receives the signal and then performs detection and analysis through the control component 170. After each detection is completed, the control component 170 controls the moving component 120 to move the fiber optic connector 220 on the mounting base 150. This moves the fiber optic connector 220 to be tested on the mounting base 150 to the detection component 140 for testing, eliminating the need for repeated plugging and unplugging of the fiber optic connector 220 and reducing the time spent on plugging and unplugging.

[0052] The port is equipped with a signal transmitter for transmitting test optical signals.

[0053] The moving component 120 has two embodiments: a rotating component 121 and a translation component 122.

[0054] like Figure 1-3 as well as Figure 5 As shown, when the moving component 120 is a rotating component 121:

[0055] In this embodiment, the moving component 120 includes a rotating component 121, and a control component 170 controls the rotating component 121 to rotate, causing the fiber optic connector 220 of the output end 212 of the corresponding optical cable 210 to be tested to rotate to the detection position. That is, rotation is used to rotate the fiber optic connector 220 of the output end 212 of the corresponding optical cable 210 to be tested to the detection component 140, and finally the control component 170 detects the signal emitted from the fiber optic output end 212. By rotating and sequentially aligning the components, multiple tests are performed, which can accelerate the detection efficiency.

[0056] like Figure 1-3In this embodiment, the projection of the detection component 140 onto the rotating component 121 is located on the moving path of the plurality of mounting bases 150. By having the projection of the detection component 140 onto the rotating component 121 located on the moving path of the plurality of mounting bases 150, the signal emitted by the fiber optic connector 220 inserted into the mounting base 150 can be collected by the detection component 140, preventing problems such as failure to receive the signal emitted by the fiber optic connector 220 or incomplete signal reception.

[0057] like Figure 1-3 In this embodiment, the rotating assembly 121 includes a turntable 1211 and a first motor 1212. The turntable 1211 is mounted on the first motor 1212. Multiple mounting seats 150 are mounted on the turntable 1211, and the multiple mounting seats 150 are arranged at equal angular intervals on the turntable 1211. After each detection assembly 140 completes a detection, the control assembly 170 controls the first motor 1212 to rotate the turntable 1211, and moves the corresponding fiber optic connectors 220 inserted on the corresponding mounting seats 150 to the detection position. By using multiple mounting seats 150 arranged at equal angular intervals on the turntable 1211, the precise angle of rotation can be analyzed based on the same angle when the control assembly 170 controls the first motor 1212 to rotate the turntable 1211, preventing the problem of inaccurate detection due to difficulty in controlling the rotation angle caused by uncertain angles.

[0058] The first motor 1212 is a stepper motor. The rotation angle and stop gap of the stepper motor are adjusted by the control component 170, so that the detection time and detection time gap can be accurately utilized. That is, when the control component 170 detects the signal emitted by the fiber optic connector 220 of the fiber optic output end 212, the first motor 1212 stops. When the control component 170 analyzes the detected data, the control component 170 simultaneously controls the first motor 1212 to rotate so that the fiber optic connector 220 on the next mounting base 150 to be detected rotates to the detection component 140.

[0059] The optimal number of mounting bases 150 installed on the turntable 1211 is two or more, with eight being the most suitable number. When there are eight mounting bases 150, the angle between two adjacent mounting bases 150 is 45 degrees.

[0060] When the moving component 120 is the translation component 122:

[0061] like Figure 4 and Figure 6As shown, in this embodiment, the moving component 120 includes a translation component 122, and the control component 170 controls the translation component 122 to move, so that the fiber optic connector 220 of the output end 212 of the corresponding optical cable 210 to be tested moves to the detection position. That is, by translation, the fiber optic connector 220 of the output end 212 of the corresponding optical cable 210 to be tested is rotated to the detection component 140, so that the mounting base 150 is aligned with the detection component 140. Finally, the detection component 140 detects the signal emitted by the fiber optic connector 220 of the optical cable output end 212. By sequentially aligning through translation, multiple tests are performed, which can accelerate the detection efficiency.

[0062] like Figure 4 and Figure 6 As shown, in this embodiment, the projection of the detection component 140 onto the translation component 122 is located along the movement path of the plurality of mounting bases 150. By ensuring that the projection of the detection component 140 onto the translation component 122 is located along the movement path of the plurality of mounting bases 150, the signal emitted by the fiber optic connector 220 inserted into the mounting base 150 can be collected by the detection component 140, preventing problems such as failure to receive the signal emitted by the fiber optic connector 220 or incomplete signal reception.

[0063] like Figure 4 and Figure 6 As shown, in this embodiment, the translation component 122 includes a carrier 1223 and a drive component 1224; a mounting base 150 is mounted on the carrier 1223, and multiple mounting bases 150 are arranged at equal intervals on the carrier 1223; the drive component 1224 can drive the carrier 1223 to move the mounting bases 150; each time the detection component 140 completes a detection, the control component controls the drive component 1224 to translate the carrier component, and moves the corresponding fiber optic connectors 220 inserted on the mounting bases 150 to the detection position. By using multiple mounting bases 150 arranged at equal intervals on the carrier 1223, the precise translation distance can be analyzed based on the equal intervals when the control component 170 controls the drive component 1224 to translate the carrier 1223, preventing the problem of inaccurate detection due to difficulty in controlling the translation distance caused by uncertain distance.

[0064] like Figure 4 and Figure 6 As shown, in this embodiment, the translation component 122 further includes a mounting base 150 and a track 1222; the track 1222 is disposed on the mounting base 150, and the carrier 1223 is mounted on the track 1222, allowing the carrier 1223 to translate linearly along the track 1222; the driving component 1224 is mounted on the mounting base 150, and the driving component 1224 drives the carrier 1223 to move. In other words, the driving component 1224 pushes the carrier 1223 to move along the track 1222, making operation simple and convenient.

[0065] like Figure 4 and Figure 6 As shown, in one embodiment, the driving component 1224 includes a second motor 122a and a screw 122b; the second motor 122a and the screw 122b are mounted on the mounting base 150, and the second motor 122a can drive the screw 122b to rotate; the carrier component 1223 is provided with an internal thread; the carrier component 1223 is mounted on the screw 122b via the internal thread; when the second motor 122a rotates, the screw 122b drives the carrier component 1223 to move along the track 1222. That is, the second motor 122a drives the screw 122b to rotate, and the screw 122b pushes the carrier component 1223 to move via the thread; and the use of the screw 122b for pushing, based on the self-locking property of the screw 122b, can ensure the stability of the carrier component 1223 when it stops pushing the carrier component 1223 to move, thus ensuring the stability of the control component 170 during detection.

[0066] The second motor 122a is a stepper motor. The translation distance and stop gap of the stepper motor are adjusted by the control component 170, so that the detection time and detection time gap can be accurately utilized. That is, when the control component 170 detects the signal emitted by the fiber optic connector 220 of the fiber optic output end 212, the second motor 122a stops. When the control component 170 analyzes the detected data, the control component 170 simultaneously controls the second motor 122a to rotate so that the fiber optic connector 220 on the next mounting base 150 to be detected is translated to the detection component 140.

[0067] In other embodiments, the drive member 1224 may also employ a gear and rack combination; that is, the gear is mounted on the mounting base 150, one end of the rack is fixed to the carrier member 1223, the gear rotates to drive the rack to move, and the rack drives the carrier member 1223 to move along the track 1222.

[0068] In one embodiment, when the optical fiber 210 has 32 cores, the optical fiber 210 includes two optical fiber connectors 220 and four optical fiber connectors 220; and each optical fiber connector 220 contains 16 cores, and each optical fiber connector 220 contains 8 cores; each optical fiber connector 220 is connected to one of the ports 130; and each optical fiber connector 220 is connected in sequence to a mounting base 150.

[0069] In the second embodiment, when the optical fiber 210 has 64 cores, the optical fiber 210 includes four optical fiber connectors 220 and eight optical fiber connectors 220; and each optical fiber connector 220 contains 16 cores and each optical fiber connector 220 contains 8 cores; each optical fiber connector 220 is connected to one of the ports 130; each optical fiber connector 220 is connected to a mounting base 150 in sequence.

[0070] The use of a multi-port 130 and multiple mounting bases 150 enables simultaneous testing of fiber optic connectors 220 with different core counts, making testing more convenient.

[0071] like Figure 5-6 As shown, in this embodiment, a busbar 160 is inserted into port 130; a first connector 161 is provided at the other end of the busbar 160; the busbar 160 is connected to the fiber optic connector 220 of the fiber optic input terminal 211 via the first connector 161; when port 130 sends a signal, the signal is sent into the optical fiber via the first connector 161 and the fiber optic connector 220. Using the busbar 160 to connect port 130 and the fiber optic connector 220 of the fiber optic input terminal 211 can prevent the problem of difficulty in inserting the fiber optic connector 220 of the fiber optic input terminal 211 when directly connected to port 130; while connecting via the busbar 160 facilitates connection through the extension of the busbar 160.

[0072] like Figure 3-4 As shown, the detection component 140 includes a detection window 141; the detection window 141 is used to receive the optical signal transmitted by the optical fiber connector 220 of the output end 212; the control component 170 is used to analyze the optical signal to obtain the detection result. That is, the signal emitted by the optical fiber connector 220 of the optical fiber output end 212 enters through the detection window 141, is then detected and analyzed by the control component 170, and abnormal data is recorded.

[0073] like Figure 1-6 As shown, this embodiment provides a fiber optic connector testing method, which uses a fiber optic connector testing device 100 to test a fiber optic connector 220, including:

[0074] First, connect the fiber optic connector 220 of the input end 211 of the optical cable 210 to the first connector 161 on the bus 160 in sequence; then connect the fiber optic connector 220 of the output end 212 of the optical cable 210 to the mounting base 150 in the same order as the input end 211 of the optical cable 210.

[0075] That is, the order in which the fiber optic connector 220 on the input end 211 of a fiber optic cable 210 is inserted into the first connector 161 on the corresponding bus 160 is determined by the position of the fiber optic connector 220 on the output end 212 of a fiber optic cable 210; and the order in which the fiber optic connector 220 is inserted into the corresponding mounting base 150 is determined by the position of the fiber optic connector 220 on the output end 212 of a fiber optic cable 210; this prevents the recording order from being reversed during testing, which could lead to errors.

[0076] Then, control component 170 activates detection component 140;

[0077] The control component 170, based on polarity information, causes the port 130 of the fiber optic connector 220 test device 100 to emit detection light into the target fiber in the fiber optic connector 220 at the output end 212 of the corresponding optical cable 210, and controls the moving component 120 to move so that the fiber optic connector 220 corresponding to the output end 212 of the optical cable 210 moves to the detection position.

[0078] The detection component 140 receives the optical signal transmitted by the fiber optic connector 220 at the output end 212 located at the detection position;

[0079] The control component 170 acquires the optical signal received by the detection component 140 and obtains the detection result.

[0080] The control component 170 controls the movement of the moving component 120, thereby controlling the order of detection, which can effectively detect the target optical fiber and ensure the effectiveness and stability of the detection.

[0081] Installation and implementation steps;

[0082] 1. Before use, complete the insertion of bus 160 and port 130, and there is no need to unplug bus 160 during use;

[0083] 2. Connect the fiber optic connector 220 of the input end 211 of the optical cable to be tested to the first connector 161 on the bus 160 in sequence; then connect the fiber optic connector 220 of the output end 212 of the same optical cable to the mounting base 150 in sequence.

[0084] 3. Start the signal transmitter to emit a test optical signal to port 130, and control component 170 starts to receive the optical signal;

[0085] 4. The test optical signal passes sequentially through bus 160, first connector 161, fiber optic connector 220 of input end 211, optical fiber in optical cable 210 and fiber optic connector 220 of output end 212; then the optical signal is transmitted to control component 170 through detection window 141.

[0086] 5. After receiving the optical signal, the control component 170 simultaneously controls the movement component 120 to move and analyze the optical signal to obtain the polarity information of the optical fiber connector.

[0087] 6. When the moving component 120 is moved, the control component 170 will determine whether there is an untested channel in the fiber optic connector 220 based on the polarity information; if there is an untested channel, the control component 170 will control the moving component 120 to move the next fiber optic connector 220 to be tested to the detection position.

[0088] 7. During optical signal analysis, the analysis results and the detection location will be recorded.

[0089] 8. Whenever the control component 170 completes a reception, it will perform an analysis and control the moving component 120 to move once;

[0090] 9. Continue testing until the fiber optic connectors 220 on the entire optical cable 210 are completed.

[0091] In summary, this utility model provides a fiber optic connector testing device. After the control component completes one test on the fiber optic connector on the mounting base of the testing component, the control component only needs to control the translation component to move the fiber optic connector on the mounting base to the testing component. This moves the fiber optic connector to be tested on the mounting base to the testing component, eliminating the need for repeated plugging and unplugging of the fiber optic connector and thus saving a lot of time spent on plugging and unplugging.

[0092] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
