Description

Technical Field

[0001] The present invention belongs to the technical field of optical device product testing, and relates to a three-temperature testing system, in particular to a high-efficiency three-temperature automatic testing device, system and method. Background Art

[0002] In recent years, with the development of the global communications industry and strong national support for the sector, 5G has emerged and rapidly entered commercial use. The market demands ever-increasing demand for higher-speed, higher-quality products. Since high-speed products are primarily used in base stations, data centers, high-performance computing networks, and enterprise core networks, operating in environments with widely varying ambient temperatures and high product failure rates, ensuring the quality of optical components is crucial to supporting the smooth operation of these networks.

[0003] Under the comprehensive contradiction between market and output, three-temperature testing is an indispensable part of the entire fiber optic communication high-speed product. The research and development of high-efficiency three-temperature automatic testing system has become an important development direction for fiber optic communication companies.

[0004] Currently, test equipment in the optical fiber communications industry varies widely, both in-house and purchased, due to differences in company backgrounds and capabilities. Currently used three-temperature test systems are either manual plug-in test systems or use optical switcher-based equipment, such as Pusex's TE test equipment. These test systems typically include an optical switcher, integrated tester, electrical switcher, power supply board, and chassis. Test software controls the optical and electrical switches to select a single optical output, which is then connected to the LIV and spectrometer via a 1x2 optical splitter for testing.

[0005] Currently, the industry tests optical components by manually plugging and unplugging optical fibers and manually probing each product. For optical components that must be tested at three temperatures (high, normal, and low), manual operations have low production efficiency, high labor intensity, and are prone to errors. When testing batch products at three temperatures, companies need to invest more manpower, material resources, and financial resources to test the products, resulting in increased testing costs. Furthermore, during manual plug-and-unplug testing, the fiber end faces must be cleaned and inspected each time they are tested, and factors such as production line configuration, employee emotions, and employee skills can affect test efficiency by between 150 and 300 pieces per person per 10 hours, or even lower. Therefore, companies need to optimize their testing methods and utilize fewer resources to improve product testing efficiency and accuracy. Summary of the Invention

[0044] When a three-temperature test is required on an optical fiber in this embodiment, the optical fiber to be tested is mounted on the operating platform 19. The specific installation method is as follows: the optical fiber connection flange array plate 4 is fixed within the test chamber 26. Fiber test cables are connected to the optical fiber connection flange array plate 4 in sequence. The optical fiber ends of the optical fibers to be tested are connected to the fiber test cables, and the other ends of the optical fibers to be tested are mounted on the socket power array plate 24. After the optical fiber to be tested is installed, the socket power array plate 24 is placed in the impact test chamber 13. After the test temperature is set, the probe module 21 is activated to perform the three-temperature test on the optical fiber to be tested.

[0045] In this embodiment, the provision of two sets of optical fiber fixing assemblies enables installation of one set of optical fibers to be tested while another set of optical fibers to be tested is being tested, thereby saving time for installation of the optical fibers to be tested and improving testing efficiency.

[0046] In this embodiment, the structure and working principle of the impact test box 13 belong to the existing technology, and those skilled in the art can understand it based on the existing technology and their own knowledge, so they will not be further described in this embodiment.

[0047] As a further description of the above embodiment, the optical fiber connection flange array board 4 is provided with 8*8 optical fiber connection flanges 5, and each optical fiber connection flange 5 is marked with a flange serial number in sequence. The Socket powering array board 24 is provided with 8*8 Sockets 25, and the position of the Socket 25 corresponds to the position of the optical fiber connection flange 5, and each Socket 25 is marked with a Socket serial number in sequence. The Socket powering array board 24 is connected to a relay array switch 12 that controls the powering of the optical fiber to be tested on the Socket 25 of a certain serial number, and the relay array switch 12 is controlled by the integrated test board 14.

[0048] In this embodiment, the 8*8 fiber connection flanges 5 provided on the fiber connection flange array plate 4 can simultaneously mount 64 optical fibers under test, thereby simultaneously testing all 64 optical fibers under test during a single test, improving testing efficiency. The fiber connection flanges 5 not only ensure the stability of the installation of the optical fibers under test, but also facilitate the installation and removal of the optical fibers under test, improving the efficiency of installation and removal of the optical fibers under test, thereby improving the efficiency of optical fiber three-temperature testing.

[0049] The sockets 25 of the socket power array board 24 are arranged in an array. The number and position of the sockets 25 on the socket power array board 24 match the number and position of the fiber optic connection flanges 5. Relay array switches 12 can be used to control powering a product, enabling continuous sequential testing. A socket is a power supply socket.

[0050] Each optical fiber test line is marked with an optical fiber test line serial number. The optical fiber test line serial number, flange serial number and socket serial number correspond one to one, which can facilitate the collection and recording of test data, so that the test data of each optical fiber to be tested can be accurately and quickly processed to understand the performance of each optical fiber to be tested under three temperatures.

[0051] In this embodiment, the number of optical fiber connection flanges 5 on the optical fiber connection flange array board 4 is not limited to 8*8, and can be adjusted according to actual test requirements, such as 4*4, 6*6, etc. The number and position of Socket 25 on the Socket power array board 24 can match the number and position of the optical fiber connection flanges 5.

[0052] As a further description of the above embodiment, the probe module 21 includes a first PD probe 22 and a second PD probe 23, and the first PD probe 22 and the second PD probe 23 are connected in parallel to a connecting block, and the connecting block is connected to a servo motor 18. The servo motor 18 is powered by a motor power supply 7 and a power filter 9, and the servo motor 18 is controlled by a motion control card conversion board 8.

[0053] When this embodiment is used, the probe module 21 is connected to the servo motor 18 via a connecting block. The servo motor 18 operates in a servo system that can automatically move the position of the X and Z axes. The servo system includes an XZ servo axis, and the probe module 21 is installed on the XZ servo axis. It is equipped with an X and Z axis mechanism. Each axis includes a linear guide, a wire slot (X axis slot 2, Z axis slot 17), a motor adjustment frame, a stepper motor, an automatic return device, an in-position sensor, etc. The servo system uses X and Z axis adjustment to align the probe on the probe module 21 with the fiber optic test line with the corresponding serial number, thereby achieving high precision of the device and high test accuracy.

[0054] In this embodiment, the structure and working principle of the servo system driving the probe module 21 to move on the X and Z axes belong to the existing technology, which can be known to those skilled in the art based on the existing technology and their own knowledge, so it will not be further described in this embodiment.

[0055] In this embodiment, the first PD probe 22 tests the LIV data of the optical fiber to be tested, and the second PD probe 23 tests the spectrum of the optical fiber to be tested. The sizes of the first PD probe 22 and the second PD probe 23 match the sizes of the optical fiber connection flange 5. The distance between the first PD probe 22 and the second PD probe 23 is equal to the distance between two adjacent optical fiber connection flanges 5. By adjusting the distance and position between the probe module 21 and the optical fiber connection flange array plate 4, it is ensured that the optical signal can be fully detected, thereby ensuring the accuracy of the optical fiber test results.

[0056] In this embodiment, the servo motor 18 is fixed to the test chamber 26 via the first support shaft 15 and the second support shaft 16, and the optical fiber connection flange array plate 4 is fixed to the test chamber 26 via the first support frame 3 and the second support frame 6. The holes on the frame through which the first support shaft 15, the second support shaft 16, the first support frame 3, and the second support frame 6 are fixed are all waist-shaped holes, which facilitates adjustment of the distance between the probe module 21 and the optical fiber connection flange array plate 4, ensuring that the optical signal can be fully detected, thereby ensuring the accuracy of the optical fiber test results.

[0057] As a further description of the above embodiment, the motor power supply 7, motion control card conversion board 8, power supply filter 9, integrated test board power supply 10, relay array switch 12 and integrated test board 14 are all arranged in a control room 27, and the control room 27 is also provided with an air switch 11 for controlling the equipment in the entire cabinet 1.

[0058] In this embodiment, circuit breaker 11 controls the electrical power of all equipment in cabinet 1. Motor power supply 7 and power filter 9 power servo motor 18. Integrated test board power supply 10 powers the optical fiber under test. The optical fiber under test is mounted on socket power array board 24, which is connected to relay array switch 12 via a flat cable. Integrated test board 14 controls relay array switch 12 to power the product.

[0059] Example 2

[0060] A high-efficiency three-temperature automatic testing system, comprising:

[0061] A motion control module, used to control the relative position of the probe module 21 and the optical fiber connection flange array plate 4;

[0062] The test module is used to collect data and store the data on a local computer and a network disk through the RS232 interface;

[0063] Data processing module, used to call specifications, process data and make judgments;

[0064] The relay power-on control module is used to control the relay array switch 12 , thereby powering the corresponding products on the socket power-on array board 24 .

[0065] During the automatic testing of the optical fiber under test, this embodiment selects a set of test boards. Each set of test boards corresponds to the relay array switch 12, the socket power array board 24, and the optical fiber connection flange array board 4. Open the "Version Number - Serial Number Correspondence" interface, edit the board number information, and associate the optical fiber test cord serial number, flange serial number, and socket serial number with each other. These numbers are stored in the board number file. Each test board can test up to 64 products. The other end of the optical fiber test cord on the optical fiber connection flange array board 4 is connected to the optical fiber end of the optical fiber under test, and the other end of the optical fiber under test is plugged into the corresponding socket 25. After installing a board of products, place the products in the impact test box 13, click "Start automatic test", the relay power control module controls the relay array switch 12 to power the corresponding product on the socket power array board 24, and the motion control module controls the control probe module 21 to move, automatically moving to the back of the corresponding powered optical fiber connection flange 5 to detect the optical power, working voltage, backlight current and spectral parameters of the optical device, and calculate the threshold current, power efficiency, slope efficiency, differential resistance and other parameters and draw the photoelectric characteristic (LIV) curve. While testing LIV, the spectrum will also be tested. After the measurement is completed, you can switch to the next temperature to be tested, and the temperature set in the software interface will also change accordingly. After reaching the test temperature, wait for a few minutes and click the "Start automatic test" button to continue the test. The software will also select the temperature accordingly, and calculate the TE value through LIV parameter testing at different temperatures.

[0066] In this embodiment, after the product is manually installed, during the automatic test, the relay array switch 12 switches to power on a certain product, and the probe module 21 is automatically moved by the XZ servo system to the position of the optical fiber connection flange 5 corresponding to the powered product, and the optical power under different current conditions is detected. The data is transmitted to the computer through the RS232 interface, and the data is processed and judged. After measuring one temperature to be tested, it is switched to another temperature. There is no need to manually install the product or test line. You only need to wait for the temperature to reach the test requirements and click "Start automatic test". The test system will automatically test the product and process and judge the data. The system has a high test efficiency and reduces the defects caused by personnel plugging and unplugging optical fibers, and the test data is more accurate.

[0067] In this embodiment, the automatic test system can debug and set the position where the probe module 21 stops for testing, facilitating regular maintenance. The "Auto Test Start" button can control the start of movement of the probe module 21 and the switching of the socket power position on the socket power array board 24.

[0068] In this embodiment, the RS232 interface is connected to the computer, and is provided with data feedback and data computer connection. Through the automatic test program, the entire test system is controlled and data is stored.

[0069] In this embodiment, the automatic testing program can bind the serial numbers of the test line and the power line, and automatically test all products in sequence. The performance of the products in the impact test box 13 at different temperatures is tested through the integrated test board 14, and the data is fed back to the display screen of the automatic testing equipment for calculation and processing, automatic judgment and prompt of defects, and the test data is saved in the database.

[0070] Example 3

[0071] like Figure 6 As shown, a high-efficiency three-temperature automatic testing method includes the following steps:

[0072] S1. Clamp the optical fiber to be tested and start the automatic test system;

[0073] S2. The test device automatically receives light from the optical fiber to be tested on the optical fiber connection flange array plate 4, and the first PD probe 22 tests the LIV data of the optical fiber to be tested, and the second PD probe 23 tests the spectrum of the optical fiber to be tested;

[0074] S3. Perform performance tests on the product under test at different temperatures;

[0075] S4. Test data output, processing and judgment.

[0076] During use of this embodiment, the optical fiber to be tested is mounted on the operating platform 19 using a socket power array board 24. The optical fiber to be tested on the socket power array board 24 is connected to the optical fiber connection flange array board 4 via an optical fiber test line to transmit optical signals. After the optical fiber to be tested is installed, the socket power array board 24 is placed in the impact test chamber 13, and the automatic test program is activated to test the optical fiber to be tested. The relay power control module controls the relay array switch 12 to power the corresponding optical fiber to be tested on the socket power array board 24. The motion control module controls the motion control card converter board 8 to automatically move the probe module 21 to the optical fiber connection flange 5 corresponding to the powered optical fiber to be tested, detecting optical power under different current conditions. After detection, the test data is output, processed, and evaluated to determine the performance status of the different optical fibers to be tested.

[0077] The performance test of the product under test at different temperatures includes four steps: normal temperature test, low temperature test, high temperature test and return to normal temperature.

[0078] During the normal temperature test, the temperature of the impact test chamber 13 was 25°C, and the normal temperature test duration was 3 minutes. After the normal temperature test, the temperature was lowered and stabilized for 7 minutes, and the temperature inside the impact test chamber 13 was lowered to -40°C for a low temperature test, and the low temperature test duration was 3 minutes. After the low temperature test, the temperature was raised and stabilized for 9 minutes, and the temperature inside the impact test chamber 13 was lowered to 85°C for a high temperature test, and the high temperature test duration was 3 minutes. After the high temperature test, the temperature was lowered and restored to normal temperature for 3 minutes.

[0079] In summary, the present invention can automatically perform three-temperature testing on optical fibers under test and process and judge the test data, achieving high test efficiency. Furthermore, the temperature switching process eliminates the need for manual installation of products or test cables, reducing the adverse effects of testers plugging and unplugging optical fibers, and providing more accurate test data. Furthermore, while one set of optical fibers under test is being tested, another set can be installed. Testing efficiency can reach 700 to 800 fibers per person per 10 hours, a nearly fourfold increase in efficiency, while significantly reducing the cost of supporting equipment. Therefore, the present invention effectively overcomes the various shortcomings of the prior art and possesses high industrial value.
