Description

Technical Field

[0001] This invention relates to the field of optical fiber testing technology, and in particular to a method and system for testing the performance of optical fibers. Background Technology

[0002] As the core transmission medium in the field of optical communication, optical fiber's key performance parameters, such as attenuation, dispersion, and polarization mode dispersion, directly determine the transmission rate, distance, and stability of the communication link. Therefore, performance testing is a necessary step to ensure the reliable operation of optical communication systems throughout the entire process of optical fiber manufacturing, link laying, and long-term operation and maintenance.

[0003] Currently, fiber optic performance testing involves manual operation and step-by-step testing with single equipment. In the production process, it is necessary to manually connect the fiber to different testing equipment (such as an optical time domain reflectometer to measure attenuation and a dispersion meter to measure dispersion). Testing requires carrying multiple devices on-site, and the test data needs to be manually summarized and compared.

[0004] Regarding the aforementioned technologies, in actual testing, the two ends of the optical fiber are sequentially connected to the testing instrument for testing. This process generally relies on manual operation. Due to the long process and the large number of optical fibers, it is time-consuming and labor-intensive, resulting in low efficiency in optical fiber performance testing, and there is still room for improvement. Summary of the Invention

[0005] To improve the efficiency of optical fiber performance testing, this invention provides a method and system for testing optical fiber performance.

[0006] In a first aspect, the present invention provides a method for testing the performance of optical fibers, employing the following technical solution:

[0007] A method for testing the performance of optical fibers, comprising:

[0008] Step 1: In response to the detection signal, receive the fiber type and performance indicators, wherein the performance indicators include the performance type and the range of performance standard parameters;

[0009] Step 2: Find the corresponding test wavelength based on the fiber type;

[0010] Step 3: Locate the corresponding test optical signal based on the performance category;

[0011] Step 4: Develop a test plan based on the test wavelength and test optical signal;

[0012] Step 5: The robotic arm automatically picks up the fiber optic connectors corresponding to the fiber type and inserts them into the corresponding test interfaces. Then, it tests the fiber optic cables corresponding to the fiber type according to the test plan to obtain test data.

[0013] Step 6: Compare the test data with the performance standard parameter range to obtain abnormal data and abnormal locations, and output them.

[0014] By adopting the above technical solution, the corresponding test wavelength and test optical signal are obtained through the fiber type and performance indicators to form a test scheme. Then, the fiber performance is tested according to the test scheme. Abnormal data and their corresponding locations are obtained and output based on the data. This avoids the use of the same test scheme for different fiber types, which would lead to inaccurate test data and improves the efficiency and accuracy of fiber performance testing.

[0015] Optionally, it also includes a method for handling abnormal data, which includes:

[0016] Step 7: Identify the anomaly based on the anomaly location and data;

[0017] Step 8: Determine the connector type based on the fiber optic type;

[0018] Step 9: If the abnormal location falls within the fiber optic area, obtain and implement the abnormal solution based on the abnormal location and abnormal situation;

[0019] Step 10: If the abnormal location does not fall within the fiber optic area, find the corresponding blower device number and blower scheme based on the connector type;

[0020] Step 11: Control the blower corresponding to the blower number to blow the connectors corresponding to the connector type according to the blower plan;

[0021] Step 12: After the air blowing plan is completed, retest the fiber type according to the test plan to obtain test data, and use the test data as the air blowing data;

[0022] Step 13: If the blowing data falls within the performance standard parameter range, output the blowing data as test data.

[0023] By adopting the above technical solution, the abnormal location is obtained and then analyzed to determine whether repair or cleaning is needed. If cleaning is required, the fiber optic connector is cleaned. After the cause of the abnormality is resolved, the performance test is repeated. This avoids the fiber optic connector abnormality causing inaccurate fiber optic performance test data, thereby improving the efficiency of fiber optic performance testing and the reliability of test data.

[0024] Optional, also includes:

[0025] Step 14: If the blowing data does not fall within the performance standard parameter range, repeat steps 11 to 12 until the blowing data falls within the performance standard parameter range.

[0026] Step 15: Compare the blowing data with the abnormal data one by one to obtain the change data;

[0027] Step 16: If the blowing data does not fall within the performance standard parameter range and the changing data does not exist, determine the abnormal area of ​​the interface based on the abnormal data;

[0028] Step 17: Determine the abnormal air hole number according to the interface abnormal area and the preset air hole arrangement rule;

[0029] Step 18: Obtain and implement the adjustment plan based on the abnormal air hole number.

[0030] By adopting the above technical solution, when the blowing data does not meet the standard, the blowing cleaning process is repeated. The change data is obtained by comparing the blowing data with the abnormal data. If the blowing data still does not meet the standard and there is no change data, the abnormal area of ​​the interface is identified. The abnormal blowing hole number is determined by combining the blowing hole arrangement rules and the adjustment plan is implemented. This avoids cleaning failure caused by blowing device failure and improves the reliability of fiber optic performance test data.

[0031] Optionally, the method for obtaining and implementing an adjustment plan based on the abnormal air vent number includes:

[0032] Step 180: Obtain the normal air hole number based on the air hole arrangement rule and the abnormal air hole number;

[0033] Step 181: Obtain the adjustment air hole number based on the interface abnormal area and the normal air hole number;

[0034] Step 182: Calculate the air hole adjustment angle based on the interface anomaly area and the air hole number;

[0035] Step 183: If the adjustment angle of the blower hole falls within the preset adjustable angle range, adjust the blower hole corresponding to the blower hole number according to the adjustment angle of the blower hole and blow air into the abnormal area of ​​the interface.

[0036] By adopting the above technical solution, the normal air hole number is screened out by the abnormal air hole number, and the air hole number is determined by combining the abnormal area of ​​the interface. The corresponding air hole adjustment angle is calculated, and the air hole angle adjustment and directional air blowing operation are performed only when the angle falls within the adjustable range. This avoids ineffective cleaning caused by blindly adjusting the air hole, improves the targeting and effectiveness of connector cleaning, and ensures the reliability of test data.

[0037] Optionally, it also includes a method for obtaining and executing an adjustment scheme when the adjustment angle of the blower hole does not fall within the adjustable angle range, the method including:

[0038] Step 184: Obtain the blower parameters;

[0039] Step 185: Calculate the limit angle of the air blower based on the abnormal area of ​​the interface and the normal air blower number;

[0040] Step 186: Adjust the air holes corresponding to the air hole numbers according to the limit angle of the air holes to obtain the updated angle;

[0041] Step 187: Obtain the blowing coverage area based on the blowing parameters, update angle, and interface anomaly area;

[0042] Step 188: Calculate abnormal blowing parameters based on the blowing coverage area and blowing parameters;

[0043] Step 189: Control and adjust the air blower corresponding to the air blower number to blow air according to the abnormal air blowing parameters.

[0044] By adopting the above technical solution, the limit angle of the blower hole is calculated by combining the blowing parameters with the interface abnormal area and the normal blower hole number. After adjusting the blower hole to the limit angle, the blowing coverage area is determined, the abnormal blowing parameters are calculated, and the corresponding blower hole is controlled to blow air. This avoids the omission of cleaning the interface abnormal area due to the angle not being adjustable, and improves the fault tolerance and reliability of fiber optic performance testing.

[0045] Optional, also includes:

[0046] Step 190: Decompose the blowing data to obtain the current blowing data and historical blowing data;

[0047] Step 191: If the current blowing data is consistent with the historical blowing data, do not continue to control the blowing device corresponding to the blowing device number to blow the connectors corresponding to the connector type according to the blowing plan;

[0048] Step 192: If the current blowing data still does not fall within the performance standard parameter range, find the corresponding backup device number based on the blowing device number;

[0049] Step 193: Control the blower corresponding to the standby device number to blow the connectors corresponding to the connector type according to the blower plan.

[0050] By adopting the above technical solution, the current blowing data and historical blowing data are obtained by disassembling the blowing data. When the two are consistent, the repeated blowing operation is stopped to avoid resource waste and connector damage caused by invalid operation. If the current blowing data still does not meet the standard, the backup blowing device is switched to continue the operation in time, thereby improving the efficiency and stability of fiber optic connector cleaning.

[0051] Optionally, if the abnormal location falls within the fiber optic area, the methods for obtaining and implementing an abnormal solution based on the abnormal location and circumstances include:

[0052] Step 194: Disassemble the optical fiber region to obtain the optical fiber edge region and the optical fiber core region;

[0053] Step 195: If the abnormal position falls into the fiber edge region, determine the trimming position based on the abnormal position;

[0054] Step 196: Find the corresponding clipping and reconnection schemes based on the fiber type and clipping location;

[0055] Step 197: Obtain and execute the abnormal solution based on the trimming and reconnection schemes.

[0056] By adopting the above technical solution, when the abnormal location falls into the edge area of ​​the optical fiber, the corresponding cutting and reconnection schemes are formed and executed by combining the optical fiber type and the cutting location. This avoids performance loss caused by over-processing of the core area of ​​the optical fiber and improves the pertinence and scientific nature of optical fiber anomaly handling.

[0057] Optionally, it also includes a method for obtaining and implementing an abnormal solution based on the abnormal location and abnormal situation when the abnormal location falls within the fiber core area, the method including:

[0058] Step 198: If the abnormal situation is the preset dirt situation, find the corresponding cleaning device number and cleaning plan according to the abnormal location, and use the cleaning plan as the abnormal solution;

[0059] Step 199: Control the cleaning device corresponding to the cleaning device number to clean the optical fiber corresponding to the optical fiber category according to the abnormality solution;

[0060] Step 200: If the abnormal situation is a preset loose connection situation, find the corresponding reinforcement device number and reinforcement plan according to the abnormal location and abnormal situation, and use the reinforcement plan as the abnormal solution.

[0061] Step 201: Control the hardening device corresponding to the hardening device number to harden the optical fiber corresponding to the optical fiber category according to the abnormal solution.

[0062] By adopting the above technical solution, when anomalies occur in the core area of ​​the optical fiber, the anomaly is first distinguished as dirt or loose connection, and then the corresponding anomaly solution is found and implemented. This avoids ineffective repairs or damage to optical fiber performance caused by general treatment of anomalies in the core area, and further improves the scientific nature and reliability of optical fiber anomaly handling.

[0063] Optionally, it also includes a method for finding and implementing solutions when the abnormal location does not fall within the fiber optic area, the method including:

[0064] Step 202: If the changed data exists, obtain the fiber optic connector area;

[0065] Step 203: Obtain the cutting position based on the fiber optic connector area and execute steps 196 to 197 to implement the anomaly solution;

[0066] Step 204: If the changed data does not exist, proceed to steps 192 to 193 to change the blower number and execute the blower program.

[0067] By adopting the above technical solution, when there is changed data, the fiber optic connector area can be accurately acquired and the cutting position can be determined. The appropriate cutting and reconnection scheme can then be used to perform the repair. When there is no changed data, the system can be directly switched to the backup blower to continue the cleaning operation. This avoids blindly handling anomalies in non-fiber optic areas, improves the targeting of fiber optic anomaly handling and the continuity of the testing process, and enhances the reliability of fiber optic performance measurement data.

[0068] Secondly, the present invention provides a performance testing system for optical fibers, which adopts the following technical solution:

[0069] A fiber optic performance testing system, comprising:

[0070] The acquisition module is used to acquire fiber type, performance indicators, and blowing parameters;

[0071] A memory for storing the program of the control method for the optical fiber performance testing method described above;

[0072] The processor loads and executes programs from memory.

[0073] By adopting the above technical solution, the acquisition module accurately collects core data such as fiber type, the memory stores the fiber performance testing and anomaly handling control program, and the processor loads and executes the program to realize the automated operation of the entire process of fiber performance testing, anomaly location, and differential processing. This avoids the errors and inefficiencies caused by manual operation and improves the efficiency and reliability of the fiber performance testing system.

[0074] In summary, the present invention has at least one of the following beneficial technical effects:

[0075] By obtaining the corresponding test wavelength and test optical signal based on the fiber type and performance indicators, a corresponding test scheme is formed, and the robotic arm is controlled to grip the fiber connector and insert it into the detection device. This allows the system to obtain test data and analyze abnormal data and corresponding abnormal locations, avoiding the problem of unreliable test data caused by blindly performing performance tests on the fiber, and improving the efficiency and reliability of fiber testing.

[0076] By analyzing the location of anomalies to determine the solution, the system can efficiently resolve issues related to abnormal optical fibers, avoiding the problem of slow resolution of optical fiber anomalies, improving the efficiency of optical fiber anomaly resolution, and indirectly enhancing the reliability of performance test data. Attached Figure Description

[0077] Figure 1 This is a flowchart of a fiber optic performance testing method according to an embodiment of this application. Detailed Implementation

[0078] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0079] This invention discloses a method for testing the performance of optical fibers.

[0080] Reference Figure 1 A method for testing the performance of optical fibers includes:

[0081] Step 1: In response to the detection signal, receive the fiber type and performance specifications.

[0082] The detection signal refers to the signal used to detect the performance of the optical fiber. The response here is that there is an electrical signal button on the detection device; pressing it triggers a response.

[0083] Fiber optic category refers to the type of optical fiber. Performance indicators refer to the quantitative criteria used to determine whether an optical fiber meets the applicable standards. The receiving method here involves a control panel installed on the testing device. The user inputs the fiber optic category and corresponding performance indicators for performance testing through the control panel. Performance indicators here include performance category and performance standard parameter range. Performance category refers to the specific type of test item set to determine whether the fiber optic performance meets the standards. Performance standard parameter range refers to the acceptable value range or threshold for each performance category.

[0084] Step 2: Find the corresponding test wavelength based on the fiber type.

[0085] The test wavelength refers to the specific optical signal wavelength used to detect the transmission performance of optical fibers. The method for finding this wavelength is as follows: different fiber types correspond to different test wavelengths. Personnel skilled in the field obtain the corresponding test wavelengths for each fiber type by searching relevant information online and inputting it into the system. When the system receives the fiber type, it automatically finds the test wavelength that matches the fiber type and outputs it.

[0086] Step 3: Locate the corresponding test optical signal based on the performance category.

[0087] Test optical signals refer to specific parameter optical signals used to detect the corresponding performance indicators of optical fibers. The search method here involves those skilled in the art pre-determining and inputting the matching test optical signal parameters (such as optical power, modulation method, pulse width, etc.) according to different performance categories into the system. When the system receives the performance category information, the processor automatically searches for and outputs the matching test optical signal parameters, driving the optical signal generator to generate the corresponding test optical signal.

[0088] Step 4: Develop a test scheme based on the test wavelength and test optical signal.

[0089] A test plan refers to a standardized set of operating instructions that guide the testing device to perform performance testing on optical fibers. Here, it is generated by the system integrating the matched test wavelength parameters with the test optical signal parameters to produce a standardized test plan.

[0090] Step 5: The robotic arm automatically picks up the fiber optic connectors corresponding to the fiber type and inserts them into the corresponding test interfaces. Then, it tests the fiber optic cables corresponding to the fiber type according to the test plan to obtain test data.

[0091] Test data refers to the actual performance parameter values ​​of the optical fiber, corresponding one-to-one with the performance category, collected by the testing device during the performance testing of the optical fiber according to the test plan. Here, the method of obtaining this data is as follows: the optical signal acquisition module of the testing device receives the feedback optical signal transmitted through the optical fiber in real time, converts the feedback optical signal into an electrical signal, and transmits it to the processor. The processor analyzes and calculates the electrical signal according to preset algorithms, including mature algorithms in the field of optical fiber testing such as the logarithmic power conversion algorithm for attenuation detection, the optical power reflection calculation algorithm for return loss detection, and the pulse delay analysis algorithm for bandwidth detection, extracting the actual performance parameter values ​​corresponding to each performance category as test data.

[0092] Step 6: Compare the test data with the performance standard parameter range to obtain abnormal data and abnormal locations, and output them.

[0093] Abnormal data refers to parameter values ​​in the actual performance parameters of the optical fiber obtained through testing that exceed the performance standard parameter range. Abnormal location refers to the specific physical area or component location where the optical fiber performance anomaly directly corresponds to the abnormal data. This is achieved by the system comparing each actual performance parameter value in the test data with the performance standard parameter range one by one, filtering out parameter values ​​that exceed the range as abnormal data, and simultaneously calling optical fiber performance testing location algorithms (such as the OTDR slope location algorithm). Combining the performance category corresponding to the abnormal data, the transmission timing of the test optical signal, and the characteristics of the feedback signal, the system calculates and determines the specific physical area or component location corresponding to the abnormal data as the abnormal location. The output is achieved by the system generating a detection anomaly report based on the associated abnormal data and anomaly location according to a preset format, such as a standardized PDF text report format, a CSV data file format, or an OTDR-specific SOR format, which is then visualized on the display panel of the testing device.

[0094] This also includes methods for handling abnormal data, which include:

[0095] Step 7: Identify the abnormal situation based on the abnormal location and abnormal data.

[0096] An anomaly refers to the specific manifestation type and cause of fiber optic performance anomalies determined by combining the physical properties of the anomaly location and the parameter characteristics of the anomaly data. This is achieved by those skilled in the art identifying and determining the corresponding fiber optic performance anomaly manifestation type and cause based on the physical properties of different anomaly locations and the parameter characteristics of the anomaly data, and then inputting this information into the system. When the system receives the currently detected anomaly data parameter characteristics and anomaly location physical property information, it automatically determines the specific manifestation type and cause of the fiber optic performance anomaly, thus obtaining the anomaly situation.

[0097] Step 8: Determine the connector type based on the fiber optic type.

[0098] The connector category refers to the specifications and structural type of fiber optic connectors that are compatible with the fiber optic category. This is determined by a person skilled in the art based on the compatibility relationship between fiber optic categories and connector categories, and input into the system. Upon receiving fiber optic category information, the system automatically retrieves and matches connector specifications and structural types compatible with the current fiber optic category, thereby determining the connector category.

[0099] Step 9: If the abnormal location falls within the fiber optic area, obtain and execute the abnormal solution based on the abnormal location and abnormal situation.

[0100] An optical fiber region refers to the physical segment of the optical fiber itself that does not include external components such as fiber optic connectors and test interfaces. This optical fiber region is obtained by those skilled in the art who, based on the optical fiber's production specifications, input the physical boundary information of the optical fiber itself into the system. Simultaneously, the corresponding segments for external components such as fiber optic connectors and test interfaces are marked and excluded. When the system detects abnormal location coordinates, it determines whether the location falls within the defined physical segment of the optical fiber itself, excluding external components, by comparing the coordinates. This determines whether the abnormal location falls within the optical fiber region.

[0101] An anomaly solution refers to a standardized, directly executable response plan for specific anomalies and abnormal conditions within an optical fiber area. This is achieved by individuals skilled in the art identifying and developing corresponding standardized response plans based on the physical properties of different anomalies and the specific types of anomalies within the optical fiber area, and then inputting these plans into the system. Once the system determines that an anomaly falls within the optical fiber area, it matches the combination of the current anomaly location and the anomaly condition, retrieves and outputs the corresponding standardized response plan to obtain the anomaly solution. The execution method involves the system automatically issuing instructions to the corresponding execution module after finding a matching anomaly solution. For anomalies that can be automatically handled, such as optical fiber bending damage or coating damage, the system drives a mechanical adjustment device to perform attitude correction, protective reinforcement, and other operations at the anomaly location.

[0102] If the abnormal location falls within the fiber optic area, it indicates that the abnormality is indeed occurring in the fiber optic cable, and the cause of the abnormality can be determined, thus leading to a solution. Therefore, the solution to the abnormality is obtained and implemented by analyzing the abnormal location and the abnormal situation.

[0103] Step 10: If the abnormal location does not fall within the fiber optic area, find the corresponding blower device number and blower scheme based on the connector type.

[0104] The blower device number refers to the unique code of the blower device used to clean fiber optic connectors. The lookup method involves different blower device numbers corresponding to different connector types. Personnel skilled in the art search relevant information online to obtain the blower device corresponding to each connector type, assign it a number, and input it into the system. When the system determines that the abnormal location is not within the fiber optic area, it automatically searches for and outputs the unique code of the blower device suitable for the current connector type. The blower scheme refers to the standardized combination of operating parameters used to clean fiber optic connectors, matching the fiber optic connector type and its corresponding blower device number. The lookup method involves personnel skilled in the art developing a corresponding standardized cleaning operating parameter combination based on different fiber optic connector types and their corresponding blower device numbers, combined with the structural characteristics of the fiber optic connector, cleaning requirements, and the operating parameters of the blower device. This combination is then input into the system. When the system retrieves the blower device number suitable for the current connector type, it automatically searches for and outputs the corresponding standardized cleaning operating parameter combination based on the combination information of the connector type and the blower device number.

[0105] If the abnormal location does not fall within the fiber optic area, it indicates that the data anomaly is not caused by a problem with the fiber optic cable. In order to determine whether the abnormal location is on the connector, the corresponding blower device number and blower scheme are searched based on the connector type.

[0106] Step 11: Control the blower corresponding to the blower number to blow the connectors corresponding to the connector type according to the blower plan.

[0107] The air blowing method here is as follows: after the system matches the air blowing device number and the corresponding air blowing scheme, it sends a start command to the execution unit corresponding to the air blowing device number. After receiving the command, the air blowing device sprays directional airflow at the end face and gap position of the fiber optic connector corresponding to the connector type according to the preset parameters such as air blowing pressure, air blowing duration, airflow direction, gas purity and number of cleaning cycles in the air blowing scheme, so as to complete the connector cleaning operation.

[0108] Step 12: After the air blowing plan is completed, retest the fiber type according to the test plan to obtain test data, and use the test data as the air blowing data.

[0109] The blow-out data refers to the fiber optic performance test data obtained after the fiber optic connector has undergone a blow-out cleaning operation and is retested. The method for obtaining this blow-out data is the same as the method for obtaining test data described in step 5, and will not be repeated here.

[0110] After the air blowing procedure was completed, it was indicated that the connectors had been cleaned. In order to determine whether there were any abnormalities in the connectors, the fiber type was tested again according to the test procedure to obtain test data, which was then used as the air blowing data.

[0111] Step 13: If the blowing data falls within the performance standard parameter range, output the blowing data as test data.

[0112] If the airflow data falls within the performance standard parameter range, it indicates that the original abnormality was caused by incomplete cleaning of the connector, and therefore the airflow data is output as test data.

[0113] This also includes:

[0114] Step 14: If the blowing data does not fall within the performance standard parameter range, repeat steps 11 to 12 until the blowing data falls within the performance standard parameter range.

[0115] If the air blowing data does not fall within the performance standard parameter range, it means that a single cleaning may not be able to clean the fiber optic connector without contamination. Therefore, repeat steps 11 to 12 until the air blowing data falls within the performance standard parameter range.

[0116] Step 15: Compare the blowing data with the abnormal data one by one to obtain the change data.

[0117] Change data refers to data where the same fiber performance test data changes between the air-blowing data after cleaning and the abnormal data before cleaning. This is obtained by the system retrieving both the abnormal data before and after cleaning of the fiber connector, extracting the same fiber performance test indicators (attenuation value, reflection coefficient, insertion loss, etc.) from both sets of data, performing difference calculations on the extracted indicators of the same category, where the difference calculation involves subtracting the abnormal data from the corresponding indicator's air-blowing data, and then integrating the resulting change data.

[0118] Step 16: If the blowing data does not fall within the performance standard parameter range and the changing data does not exist, determine the abnormal area of ​​the interface based on the abnormal data.

[0119] An interface anomaly area refers to a specific localized area within the connection between the fiber optic connector and the testing equipment or other fiber optic components, where poor contact, residual dirt, structural damage, or other factors cause abnormal fiber optic performance test data. This area is identified by those skilled in the art who pre-determine common anomaly types based on the structural characteristics and connection methods of the fiber optic connector and input them into the system. When the system determines that the blowing data does not fall within the performance standard parameter range and no changing data exists, it retrieves the anomaly data before cleaning, extracts the core performance indicator anomaly characteristics, performs a search and matching, and automatically locates and outputs the specific localized area of ​​the interface causing the data anomaly.

[0120] Step 17: Determine the abnormal air hole number according to the interface abnormal area and the preset air hole arrangement rule.

[0121] The air hole arrangement rule refers to the standardized layout scheme of the air hole distribution location, diameter, number, and airflow injection angle of the air blowing device. This air hole arrangement rule is obtained by those skilled in the art by inputting core parameters such as the distribution location, diameter, number, and airflow injection angle of the air holes into the system. The system then integrates the relevant data to form the air hole arrangement rule. The abnormal air hole number refers to the unique code of the air hole that precisely matches the location and range of the interface anomaly area. This is determined by the system using a spatial location matching algorithm. Based on the determined location coordinates and range parameters of the interface anomaly area, combined with the distribution location, injection angle, and coverage area of ​​each air hole in the air hole arrangement rule, the system compares the range of the interface anomaly area with the coverage area of ​​each air hole using a spatial location matching algorithm. Air holes whose coverage area completely or partially includes the interface anomaly area are selected, and their unique numbers are extracted as the abnormal air hole numbers.

[0122] Step 18: Obtain and implement the adjustment plan based on the abnormal air hole number.

[0123] The adjustment scheme refers to a standardized operating procedure for optimizing the working parameters of abnormal blowers. Here, it is obtained by those skilled in the art based on the characteristics of different abnormal interface areas, the arrangement parameters of abnormal blowers, and cleaning requirements. A standardized adjustment scheme, including parameters such as airflow pressure adjustment value, single blow duration, number of cleaning cycles, and fine-tuning angle of airflow jet direction, is entered into the system. Once the system determines the abnormal blower number, it automatically retrieves and outputs an optimized combination of operating parameters suitable for the current abnormal blower number, based on the location and contamination level characteristics of the located abnormal interface area. The execution method involves the system, after outputting the matching adjustment scheme, issuing parameter adjustment instructions to the blower execution unit corresponding to the abnormal blower number. According to the airflow pressure adjustment value, single blow duration, number of cleaning cycles, and fine-tuning angle of airflow jet direction in the scheme, the working parameters of the abnormal blower are precisely configured. Then, the corresponding abnormal blower is driven to initiate directional cleaning operations, targeting and cleaning the abnormal interface area.

[0124] The method for obtaining and implementing an adjustment plan based on the abnormal air vent number includes:

[0125] Step 180: Obtain the normal air hole number based on the air hole arrangement rules and the abnormal air hole number.

[0126] The normal air hole number refers to the unique number of all air holes except for the abnormal air holes. This number is obtained by the system using a set difference operation to remove the abnormal air hole numbers from the total number of air hole numbers based on all air hole numbers included in the air hole arrangement rules, and then summarizing and organizing the remaining air hole numbers to obtain the normal air hole number.

[0127] Step 181: Obtain the adjustment air hole number based on the interface abnormal area and the normal air hole number.

[0128] The adjusted blower hole number refers to the unique number of a blower hole whose coverage area partially overlaps with the interface abnormal area or can assist in enhancing the cleaning effect of the abnormal area. This number is obtained by the system using a spatial location matching algorithm. Based on the location coordinates and range parameters of the interface abnormal area, combined with the distribution location, spray angle, and coverage area information of each blower hole corresponding to the normal blower hole number, the system compares the coverage area of ​​each normal blower hole with the interface abnormal area. Normal blower holes whose coverage area partially overlaps with the interface abnormal area or can provide an auxiliary cleaning angle for the abnormal area are selected, and their unique numbers are extracted to obtain the adjusted blower hole number.

[0129] Step 182: Calculate the air hole adjustment angle based on the interface abnormal area and the air hole number.

[0130] The air vent adjustment angle refers to the correction value for the spatial position deviation between the initial spray angle of the air vent and the abnormal area of ​​the interface. The calculation method involves the system constructing a three-dimensional coordinate system using spatial geometry algorithms based on the initial spray angle parameters of the air vent, the installation coordinates, and the center coordinates of the abnormal area of ​​the interface. The installation position of the air vent is set as the origin, and the initial spray direction is used as the reference axis. The spatial angle between the center position of the abnormal area of ​​the interface and the reference axis is calculated. This angle is the composite angle of the horizontal deflection angle and the vertical pitch angle. The composite angle is then decomposed into horizontal and vertical directions to obtain the angle correction values ​​of the air vent in both directions. Finally, the horizontal deflection angle and the vertical pitch angle are integrated to obtain the air vent adjustment angle.

[0131] Step 183: If the adjustment angle of the blower hole falls within the preset adjustable angle range, adjust the blower hole corresponding to the blower hole number according to the adjustment angle of the blower hole and blow air into the abnormal area of ​​the interface.

[0132] The adjustable angle range refers to the range of angles within which the jet direction of the blower can be safely deflected. This adjustable angle range is obtained by those skilled in the art based on the mechanical structure design parameters of the blower, the motion limits of the transmission components, and the protection requirements of the fiber optic connectors. The maximum safe deflection angle range of the blower in the horizontal and vertical directions is then input into the system.

[0133] The method for blowing air into the abnormal interface area is as follows: the system sends a start command to the execution unit corresponding to the adjusted air hole number based on the adjusted air hole spray angle. The adjusted air hole completes the spray direction calibration according to the calculated horizontal deflection angle and vertical pitch angle, and then sprays airflow directionally into the abnormal interface area.

[0134] If the adjustment angle of the blower hole falls within the adjustable angle range, it means that the abnormal area of ​​the interface can be cleaned by blowing air through the blower hole by adjusting the angle of the blower hole. Therefore, adjust the blower hole corresponding to the blower hole number according to the adjustment angle of the blower hole and blow air through the abnormal area of ​​the interface.

[0135] This also includes a method for obtaining and executing an adjustment plan when the adjustment angle of the air blower hole does not fall within the adjustable angle range. This method includes:

[0136] Step 184: Obtain the blowing parameters.

[0137] The blowing parameters refer to the operating parameters of the blowing holes during directional purging operations. These parameters are obtained in real-time from the system's built-in sensor monitoring module, which collects data on the operating status of the blowing holes during the directional purging process.

[0138] Step 185: Calculate the limit angle of the blower hole based on the abnormal area of ​​the interface and the normal blower hole number.

[0139] The limit angle of the blower hole refers to the maximum angle threshold at which the spray direction of the blower hole can be adjusted. The calculation method here is as follows: the system constructs a three-dimensional spatial coordinate system based on the installation coordinates of the normal blower hole, the initial spray angle parameters, and the center position coordinates of the interface abnormal area. With the installation position of the normal blower hole as the origin and the maximum allowable deflection stroke of its mechanical transmission structure as a constraint, the maximum angle threshold at which the spray direction of the blower hole points to the boundary of the interface abnormal area is calculated as the limit angle of the blower hole.

[0140] Step 186: Adjust the air holes corresponding to the air hole numbers according to the limit angle of the air holes to obtain the updated angle.

[0141] The adjustment method here involves the system issuing a command to the angle adjustment execution unit corresponding to the air blower number. This execution unit drives the air blower's injection direction mechanism to adjust the horizontal deflection and vertical pitch angles according to the air blower's limit angle. The update angle refers to the final injection angle value determined after the air blower adjustment. This is obtained by the system directly setting the air blower's limit angle as the final injection angle of the adjusted air blower, using this as the update angle.

[0142] Step 187: Obtain the blowing coverage area based on the blowing parameters, update angle, and interface abnormal area.

[0143] The airflow coverage area refers to the physical range that effectively acts on the surface of the fiber optic interface when the adjusted airflow orifice sprays air according to the airflow parameters. This area is obtained by the system using the updated airflow parameters such as the adjusted airflow orifice angle, airflow pressure, and flow velocity, as well as the three-dimensional coordinates and boundary dimensions of the abnormal area of ​​the interface. Combined with a fluid dynamics simulation model, the system inputs these parameters to simulate the airflow diffusion trajectory and calculates the effective range of the airflow on the fiber optic interface surface as the airflow coverage area.

[0144] Step 188: Calculate abnormal blowing parameters based on the blowing coverage area and blowing parameters.

[0145] Abnormal blowing parameters refer to the blowing parameters that can clean the abnormal area of ​​the interface after the normal blowing aperture angle is adjusted to the limit angle. The calculation method here is as follows: the system identifies the abnormal sub-regions not covered by the blowing coverage area based on the spatial coordinates and range size of the blowing coverage area, the complete boundary information of the abnormal area of ​​the interface, and the current baseline blowing parameters, combined with spatial overlap analysis. Then, based on the airflow diffusion attenuation model, the system calculates the airflow pressure compensation value and flow velocity correction coefficient required for the uncovered sub-regions. By increasing the airflow pressure to expand the effective purging radius, or adjusting the flow velocity to optimize the directional concentration of the airflow, the system also considers the protection threshold of the fiber optic interface. The protection threshold here is a critical value obtained by the professionals in the field to avoid interface damage and is input into the system to determine the extension ratio of the single blowing time and the number of purging cycles to ensure that the airflow can continuously act on the uncovered area. Finally, the optimized airflow pressure, flow velocity, blowing time and number of cycles are integrated to obtain the abnormal blowing parameters that can completely cover and clean the abnormal area of ​​the interface.

[0146] Step 189: Control and adjust the air blower corresponding to the air blower number to blow air according to the abnormal air blowing parameters.

[0147] The blowing method here is that the system sends a control command containing abnormal blowing parameters to the execution module corresponding to the blowing hole number, drives the blowing hole to keep the updated angle unchanged, and blows the abnormal area of ​​the interface according to the optimized airflow pressure, flow rate, single blowing time and number of cycles.

[0148] This also includes:

[0149] Step 190: Decompose the blowing data to obtain the current blowing data and historical blowing data.

[0150] Current blow-through data refers to the performance data obtained after the current blow-through operation of the fiber optic interface anomaly area. Historical blow-through data refers to the fiber optic performance data obtained after the previous blow-through operation of the same fiber optic interface anomaly area. This is achieved by the system locking all performance data associated with all blow-through operations for that fiber optic cable, using the completion timestamp of the current blow-through operation as the dividing point. Fiber optic performance data collected after that timestamp is used as current blow-through data, while performance data obtained after the previous blow-through operation of the same fiber optic interface anomaly area before that timestamp is used as historical blow-through data.

[0151] Step 191: If the current blowing data is consistent with the historical blowing data, do not continue to control the blowing device corresponding to the blowing device number to blow the connectors corresponding to the connector type according to the blowing plan.

[0152] If the current blowing data is consistent with the historical blowing data, it indicates that the blowing device may be abnormal and unable to clean the contamination on the joint. Therefore, the blowing device corresponding to the blowing device number will not continue to blow the joints corresponding to the joint category according to the blowing plan.

[0153] Step 192: If the current blowing data does not fall within the performance standard parameter range, find the corresponding backup device number based on the blowing device number.

[0154] The backup device number refers to a unique identifier for a redundant blower with the same specifications, functions, and interface compatibility as the currently faulty or substandard blower. The lookup method involves assigning a backup device to each blower with a specific backup device number. These backup devices are assigned numbers by professionals in the field and entered into the system. When the system detects that the current blower data is still outside the performance standard parameter range, it automatically retrieves and matches the corresponding backup device number based on the blower number.

[0155] If the current blower data does not fall within the performance standard parameter range, it indicates that the blower corresponding to the blower device number may be damaged, causing an abnormality and making it impossible to completely clean the fiber optic connector. Therefore, the corresponding backup device number should be found based on the blower device number.

[0156] Step 193: Control the blower corresponding to the standby device number to blow the connectors corresponding to the connector type according to the blower plan.

[0157] The blowing method here is the same as that described in step 11, only the blowing device is changed.

[0158] Among them, if the abnormal location falls within the fiber optic area, the methods for obtaining and implementing an abnormal solution based on the abnormal location and abnormal situation include:

[0159] Step 194: Disassemble the fiber region to obtain the fiber edge region and the fiber core region.

[0160] The fiber edge region refers to the two ends of the fiber along its axial direction. The fiber core region refers to the main body of the fiber remaining after removing the edge regions at both ends. This is obtained by the system retrieving the total axial length parameters of the fiber under test and the edge region length threshold. Starting from the two axial endpoints of the fiber, fiber segments corresponding to the length threshold are cut inwards. These two fiber segments are defined as the fiber edge region. The length threshold is set by those skilled in the art, for example, 5mm. The main body of the fiber between these two segments is then defined as the fiber core region.

[0161] Step 195: If the abnormal position falls into the fiber edge region, determine the trimming position based on the abnormal position.

[0162] The cutting position refers to the precise axial position line defined between the abnormal location and the fiber end to perform the cutting operation, in order to completely remove the abnormal part within the fiber edge region. This is determined by the system acquiring the precise axial coordinates of the abnormal location within the fiber edge region, using this abnormal location as the inner boundary, and drawing the cutting line towards the fiber end.

[0163] Step 196: Find the corresponding cutting and reconnection schemes based on the fiber type and cutting location.

[0164] A cutting scheme refers to a standardized operational process that includes the selection of cutting tools, cutting accuracy parameters, cutting environment requirements, cutting operation steps, and post-cutting surface treatment. A reconnection scheme refers to a standardized operational process that includes connector selection, end-face cleaning process, fusion or cold splicing parameter settings, connector encapsulation steps, and post-reconnection performance testing standards. The search method here is that different fiber types and cutting locations correspond to different cutting and reconnection schemes. Personnel in this field create cutting and reconnection schemes based on their experience and by searching relevant online resources, and then input these schemes into the system. When the system receives the cutting location, it automatically retrieves and matches a unique cutting and reconnection scheme.

[0165] Step 197: Obtain and execute the abnormal solution based on the trimming and reconnection schemes.

[0166] An anomaly solution refers to the entire process of removing the abnormal section, reconnecting the fiber optic cable, and restoring its performance. This is achieved by the system logically integrating the matched trimming and reconnection solutions, linking the tool selection, process parameters, operating steps, and quality standards of both solutions to form a comprehensive anomaly solution covering the entire handling process. The execution method involves the system breaking down the integrated anomaly solution into step-by-step instructions, which are sequentially issued to the cutting, cleaning, fusion splicing or cold splicing, and testing modules. Each module strictly follows the tool selection, process parameters, and operating specifications outlined in the solution to complete its corresponding process.

[0167] This also includes a method for obtaining and implementing an abnormal solution based on the abnormal location and circumstances when the abnormal location falls into the core area of ​​the optical fiber. This method includes:

[0168] Step 198: If the abnormal situation is the preset dirt situation, find the corresponding cleaning device number and cleaning plan according to the abnormal location, and use the cleaning plan as the abnormal solution.

[0169] Contamination refers to an abnormal state in which the surface of an optical fiber is covered with foreign matter such as dust, oil, and debris, but without any physical damage such as breakage or fracture of the fiber itself. This contamination information is obtained by those skilled in the art, who, based on their professional experience, search industry technical literature, consult optical fiber maintenance standards and specifications, and review publicly available online cases of optical fiber contamination. They then summarize and categorize different types of contamination, such as dust, oil, and debris, along with their corresponding characteristic parameters. The classification standards, characteristic descriptions, and judgment criteria for these contamination conditions are then compiled into structured data and entered into the system.

[0170] The cleaning device number refers to the unique identifier of various specialized cleaning devices. The lookup method involves assigning unique identifiers to existing cleaning devices based on the type of dirt present in different locations. When the system detects dirt in the fiber optic core area, it automatically retrieves and matches the corresponding cleaning device, outputting its identifier. The cleaning plan refers to a standardized operational procedure for cleaning different types of dirt on the fiber optic cable. The lookup method involves developing a standardized cleaning procedure based on the combination of different abnormal locations (e.g., edge areas, core areas) and different types of dirt (dust, oil, debris) on the fiber optic cable, and inputting this procedure into the system. When the system detects dirt in the fiber optic core area, it automatically extracts the abnormal location and dirt type information, performs a precise search, matches, and outputs the corresponding cleaning plan.

[0171] If the abnormality is due to dirt or grime, it means that the core area of ​​the optical fiber is only contaminated and only needs to be cleaned. Therefore, find the corresponding cleaning device number and cleaning plan based on the location of the abnormality, and use the cleaning plan as the solution to the abnormality.

[0172] Step 199: Control the cleaning device corresponding to the cleaning device number to clean the optical fiber corresponding to the optical fiber category according to the abnormality solution.

[0173] The cleaning method here is that the system accurately cleans the dirty area according to the cleaning device corresponding to the matched cleaning device number, and according to the operation steps, cleaning parameters (such as cleaning pressure, cleaning frequency, consumable usage) and operation sequence in the cleaning plan.

[0174] Step 200: If the abnormal situation is a preset loose connection situation, find the corresponding reinforcement device number and reinforcement plan according to the abnormal location and abnormal situation, and take the reinforcement plan as the abnormal solution.

[0175] A loose connection refers to a situation where the fiber optic connector or fusion splice is not fully fitted, resulting in a small gap, poor contact, or loose connection. The method for obtaining information on loose connections is as follows: Those skilled in the art, combining the structural characteristics of the fiber optic connector and fusion splice with typical manifestations of loose connection faults, and by searching fiber optic connection process standards, fault cases, and experimental data, summarize and deduce the characteristics for judging loose connections (such as the range of connector gaps, the amount of displacement due to loose connection, and the fluctuation value of transmission loss). These characteristic parameters and judgment conditions are then compiled into structured data and entered into the system.

[0176] The reinforcement device number refers to various specialized reinforcement devices used to resolve loose connections at fiber optic connectors or fusion splices. The search method here involves those skilled in the art classifying different specialized reinforcement devices based on the different abnormal locations of the fiber (e.g., connector ends, fusion splice sections) and the specific manifestations of the loose connection (e.g., gap-type loose connection, loose connection) and assigning a unique number to each. When the system identifies a loose fiber connection, it automatically performs a search and matching, outputting the corresponding reinforcement device number. The reinforcement scheme refers to a standardized operational procedure for reinforcing different types of loose connections (e.g., gap-type loose connection, loose connection) and abnormal locations at fiber optic connectors or fusion splices. The search method here involves those skilled in the art combining different abnormal locations of the optical fiber (such as connector ends and fusion splices) and the specific manifestations of the loose connection (such as gap-type loose connection and loose connection) to formulate corresponding standardized reinforcement operation procedures, clarify the installation steps of the reinforcement device, tightening parameters, stress adjustment requirements, and post-reinforcement performance testing standards, and input them into the system. When the system identifies the optical fiber loose connection and matches the corresponding reinforcement device number, it automatically searches for and outputs the corresponding reinforcement solution based on the abnormal location and loose connection type information.

[0177] If the abnormality is a loose connection, it indicates that there is a problem with the fiber optic connection not being tightly fitted, gaps, or looseness. Therefore, based on the location and condition of the abnormality, find the corresponding reinforcement device number and reinforcement plan, and use the reinforcement plan as the solution to the abnormality.

[0178] Step 201: Control the hardening device corresponding to the hardening device number to harden the optical fiber corresponding to the optical fiber category according to the abnormal solution.

[0179] The reinforcement method here is to retrieve the reinforcement device corresponding to the reinforcement device number in the system, and carry out precise reinforcement work according to the operation steps, installation parameters (such as tightening torque, heat shrinking temperature, clamp positioning accuracy) and operation sequence in the reinforcement plan, targeting the type of loose connection (gap type or loose type) of the fiber optic cable at the corresponding abnormal location.

[0180] This also includes a method for finding and implementing solutions when the abnormal location does not fall within the fiber optic area. This method includes:

[0181] Step 202: If the changed data exists, obtain the fiber optic connector area.

[0182] The fiber optic connector area refers to the physical extent of the fiber optic connector itself. This area is obtained by the system extracting abnormal change data generated during fiber optic link detection, locating the link coordinates corresponding to the data fluctuations, and then combining the abnormal coordinates with the connector's physical extent parameters (such as connector length and end face diameter) to delineate the corresponding spatial area in the link topology map. Simultaneously, a visual inspection module scans this area to match the connector's appearance and structural features to determine the fiber optic connector's physical extent.

[0183] If the changed data exists but is not on the fiber itself, it indicates that the abnormal location is on the fiber connector, so the fiber connector area should be identified.

[0184] Step 203: Obtain the cutting location based on the fiber optic connector area and execute steps 196 to 197 to implement the anomaly solution.

[0185] The execution method here is the same as that described in step 197, so it will not be repeated here.

[0186] Step 204: If the changed data does not exist, proceed to steps 192 to 193 to change the blower number and execute the blower program.

[0187] The execution method here is the same as that described in step 193, and will not be repeated here.

[0188] If the change data is not found, it indicates that the problem lies with the blower. In order to clean the connector, steps 192 to 193 are performed to change the blower number and execute the blower program.

[0189] Based on the same inventive concept, embodiments of the present invention provide a performance testing system for optical fibers.
