Description

Technical Field

[0001] The present invention relates to the technical field of optical fiber operation and maintenance, and more specifically, to an optical fiber optical power detection method, system, electronic device, and storage medium. Background Art

[0002] At present, optical fiber communication is the current mainstream communication technology, which is widely used in fields such as telecommunications, broadband Internet, and mobile communication. It is the cornerstone of modern communication systems. The main transmission medium of optical fiber communication is optical fiber, which makes optical fibers widely used in communication applications such as information transmission. Therefore, it is very necessary to detect the performance and faults of optical fibers. An important detection parameter in optical fibers is optical power, which can reflect whether the optical fiber communication system is operating normally and is crucial for evaluating the performance of optical fibers, optimizing the design of optical fiber networks, and diagnosing optical fiber faults.

[0003] In the prior art, the optical power of optical fibers is mainly measured by an optical power meter. The existing optical power meters are sensitive to temperature, resulting in large detection errors of optical power. Therefore, it is necessary to make necessary improvements to the method for detecting optical power. Summary of the Invention

[0004] The present invention aims to overcome at least one defect (shortcoming) of the above prior art, and provides an optical fiber optical power detection method, system, electronic device, and storage medium, which are used to reduce the detection error of optical fiber optical power and ensure the accuracy of detected optical power.

[0005] According to the first aspect of the present application, an optical fiber optical power detection method is provided. The method includes:

[0006] Determine one or more detection holes in the optical power meter as adjustment holes;

[0007] Obtain the detection errors of the adjustment holes in different detection temperature environments, where the detection errors are obtained by the adjustment holes based on a standard optical fiber and corresponding standard optical power values;

[0008] Obtain the actual temperature value of the environment where the optical power meter is located. According to the actual temperature value and the detection errors in different detection temperature environments, confirm the initial value corresponding to the adjustment hole;

[0009] Use the adjustment hole to detect the optical fiber to be measured, and obtain the detected optical power value of the optical fiber to be measured;

[0010] Based on the initial value, correct the detected optical power value to obtain the actual optical power value of the optical fiber to be measured.

[0011] It is understandable that by obtaining the detection errors of the optical power meter in different detection temperature environments, the corresponding relationship between the detection temperature and the measurement error can be established, providing a basis for error compensation for subsequent measurements in the actual temperature environment. This method covers multiple detection temperatures, ensuring the applicability of the optical power meter in various detection temperature environments. At the same time, based on the actual detection error data, it further improves the scientificity and reliability of the calibration. In addition, according to the actual temperature value of the optical fiber to be measured and the detection error data, dynamically adjusting the initial values of each adjustment hole of the optical power meter can effectively eliminate the influence of temperature on the measurement result. This dynamic calibration mechanism can adapt to temperature changes and significantly improve the real-time performance and accuracy of the measurement. Therefore, the optical power meter of the present application is applicable to various temperature environments, greatly enhancing its scope of application.

[0012] Optionally, for obtaining the detection errors of the adjustment holes in different detection temperature environments, the detection errors are obtained by the adjustment holes based on a standard optical fiber and corresponding standard optical power values, and it includes:

[0013] Preset several detection temperatures;

[0014] Place the optical power meter successively in each of the detection temperature environments, and set the initial values of each of the adjustment holes to zero;

[0015] Successively use each of the adjustment holes to detect the standard optical fiber, and obtain the detected optical power values corresponding to each of the adjustment holes in each of the detection temperature environments;

[0016] According to the standard optical power value and the detected optical power value, obtain the detection errors corresponding to the corresponding adjustment holes in each of the detection temperature environments.

[0017] It is understandable that by presetting multiple detection temperatures, placing the optical power meter successively in each detection temperature, performing zero initialization on each adjustment hole in the optical power meter, and then detecting the standard optical fiber, obtaining the detected optical power values corresponding to each adjustment hole at each detection temperature, and further calculating the detection errors of each adjustment hole in different detection temperature environments based on the standard optical power value, this method can comprehensively evaluate the performance of the optical power meter under various temperature conditions, provide an accurate error compensation basis for subsequent measurement results, and thus improve the accuracy and reliability of its measurement.

[0018] Optionally, for obtaining the detection errors corresponding to the corresponding adjustment holes in each of the detection temperature environments according to the standard optical power value and the detected optical power value, it includes:

[0019] Calculate the detection difference between the standard optical power value and the detected optical power values corresponding to each of the adjustment holes in each of the detected temperature environments, and use the detection difference as the detection error of the corresponding adjustment hole in the corresponding detected temperature environment.

[0020] It can be understood that by calculating the detection difference between the standard optical power value and the detected optical power values corresponding to each adjustment hole in each detected temperature environment, and using it as the detection error of the corresponding adjustment hole in the corresponding detected temperature environment, this method can accurately quantify the performance deviation of each adjustment hole in the optical power meter at various detected temperatures, provide detailed temperature compensation data for subsequent measurements, and ensure high-precision measurement of the optical power meter within a wide temperature range.

[0021] Optionally, the determining the initial value corresponding to the adjustment hole according to the actual temperature value and the detection errors in different detected temperature environments includes:

[0022] Match the corresponding detected temperature according to the actual temperature value;

[0023] Obtain the corresponding detection error of each adjustment hole as the current error according to the matched detected temperature;

[0024] Set the initial value of each adjustment hole to zero, and use the current error to determine the initial value of the corresponding adjustment hole.

[0025] It can be understood that by determining the matched detected temperature according to the actual temperature value, obtaining the detection error corresponding to each adjustment hole at this detected temperature as the current error, and then setting the initial value of each adjustment hole to zero and adjusting according to this current error, this process can accurately compensate for the measurement deviation caused by temperature change of each adjustment hole, significantly improving the measurement accuracy and stability of the optical power meter under different temperature conditions.

[0026] Optionally, the optical power meter is provided with a temperature detection component for obtaining the actual temperature value.

[0027] It can be understood that by equipping the optical power meter with a temperature detection component, the actual temperature value of the optical fiber to be measured can be directly obtained. This improvement can monitor and compensate for the measurement deviation caused by temperature change in real time, significantly improving the measurement accuracy and reliability of the optical power meter, and ensuring accurate optical power readings under various temperature conditions.

[0028] Optionally, each adjustment hole corresponds to a hole number, and the optical power meter stores the association of the hole number corresponding to the adjustment hole, the detected temperature, and the detection error.

[0029] It is understandable that the associated storage of the hole numbers, the detection temperature, and the detection error can avoid corresponding errors that occur when subsequently searching for and adjusting the detection error of the holes, thereby improving the efficiency of finding the detection error.

[0030] Optionally, before determining one or more detection holes in the optical power meter as adjustment holes, initial value correction is also performed on each detection hole, specifically:

[0031] Obtain the standard optical power value of the standard optical fiber and the standard temperature corresponding to the standard optical power value;

[0032] Place the optical power meter in an environment with the standard temperature;

[0033] Use each detection hole of the optical power meter to detect the standard optical fiber in turn to obtain the corresponding corrected optical power value;

[0034] Calculate the correction difference between each corrected optical power value and the standard optical power value, and perform initial value correction on the corresponding detection hole of the optical power meter according to the correction difference.

[0035] It is understandable that by placing the optical power meter in a standard temperature environment, using each detection hole in the optical power meter to detect the standard optical fiber to obtain the corresponding corrected optical power value, then calculating the correction difference between each corrected optical power value and the standard optical power value, and performing initial value correction on the corresponding detection hole of the optical power meter according to the correction difference, this method can eliminate the systematic error formed in each detection hole of the optical power meter due to the manufacturing process, effectively improve the detection accuracy of the optical power meter, and ensure that it can provide more accurate and reliable optical power readings in practical applications.

[0037] An adjustment hole determination module, configured to determine one or more detection holes in the optical power meter as adjustment holes;

[0038] A detection error acquisition module, configured to acquire the detection error of the adjustment hole in different detection temperature environments, where the detection error is obtained by the adjustment hole based on the standard optical fiber and the corresponding standard optical power value;

[0039] An adjustment module, configured to acquire the actual temperature value of the environment where the optical power meter is located, and confirm the initial value corresponding to the adjustment hole according to the actual temperature value and the detection error in different temperature environments;

[0040] A detection module, configured to use the adjustment hole to detect the optical fiber to be measured, and obtain the detected optical power value of the optical fiber to be measured;

[0041] A correction module for correcting the detected optical power value based on the initial value to obtain the actual optical power value of the optical fiber to be measured.

[0042] According to a third aspect of the present application, there is provided an electronic device, including:

[0043] A memory for storing one or more computer programs;

[0044] A processor, when the one or more computer programs are executed by the processor, implementing the optical fiber optical power detection method described in the first aspect above.

[0045] According to a fourth aspect of the present application, there is provided a computer-readable storage medium storing computer instructions for causing a processor to implement the optical fiber optical power detection method described in the first aspect above when executed.

[0046] Based on any of the above aspects, an optical fiber optical power detection method, system, electronic device and storage medium provided by the embodiments of the present application determine one or more detection holes in a power meter as adjustment holes; obtain the detection errors of the adjustment holes in different detection temperature environments, where the detection errors are obtained by the adjustment holes based on a standard optical fiber and corresponding standard optical power values; obtain the actual temperature value of the environment where the power meter is located, and confirm the initial value corresponding to the adjustment hole according to the actual temperature value and the detection errors in different detection temperature environments; use the adjustment hole to detect the optical fiber to be measured to obtain the detected optical power value of the optical fiber to be measured; correct the detected optical power value based on the initial value to obtain the actual optical power value of the optical fiber to be measured. This method has the following benefits:

[0047] · Simplify the adjustment process of the power meter: By combining the standard optical power value and different detection temperature values to adjust each adjustment hole of the power meter, the adjustment efficiency can be improved, and rapid and accurate adjustment of each adjustment hole of the power meter can be achieved;

[0060] Recently, optical fiber, as an advanced communication transmission medium, has been widely used in modern communications, the Internet, and many data transmission fields. In the entire optical fiber transmission system, it is inevitable that the optical fiber will fail or be damaged during use, so it is necessary to perform daily maintenance on the optical fiber. Optical power is one of the important parameters for optical fiber maintenance. Optical power directly reflects the intensity of the optical signal in the optical fiber. It plays a key role in evaluating the performance and quality of the optical fiber communication system. Reasonable control and monitoring of the optical power of the optical fiber is an important part of ensuring the normal operation of the optical fiber communication system. There are usually many professional ways to measure the optical power of optical fiber. One of the common methods is to use an optical power meter for measurement. An optical power meter is an instrument specifically used to measure optical power. By correctly connecting the optical fiber to the optical power meter, the optical power meter can accurately measure the power value of the optical signal in the optical fiber. However, the optical power meter is sensitive to the actual temperature. If it is in an environment higher or lower than the measurement standard temperature, a large detection error will be generated. In the prior art, the resistance of the optical power meter is generally adjusted according to the temperature to reduce the error, but this method still cannot stably adjust the resistance, so that the detection error cannot be quickly reduced. Therefore, it is necessary to make necessary improvements to the method of detecting the optical power of the optical fiber.

[0061] This embodiment provides a technical solution that can solve the above-mentioned problem. The specific implementation methods of this application are described in detail below in conjunction with the accompanying drawings.

[0062] like Figure 1 As shown, this embodiment provides a method for detecting optical fiber optical power, which can be subdivided into the following steps:

[0063] S110, determining one or more detection holes in the optical power meter as adjustment holes;

[0064] In this embodiment, the optical power meter includes several detection holes. A common optical power meter has 16 detection holes. However, in actual use, there is a usage scenario where one or more of these detection holes are used. Therefore, in order to consider the adjustment efficiency, the detection holes to be used are taken as adjustment holes, and the initial values of the adjustment holes are adjusted to reduce unnecessary adjustment work.

[0065] S120. Obtain the detection error of the adjustment hole in different detection temperature environments, where the detection error is obtained by the adjustment hole based on a standard optical fiber and a corresponding standard optical power value;

[0066] In this embodiment, the standard optical fiber has a corresponding standard optical power value, and this standard optical power value is measured using a precise measuring instrument at the corresponding standard temperature. Preferably, this measuring instrument is an optical power meter. It can be understood that an optical power meter is an instrument used to measure the power of an optical signal and is widely used in fields such as optical fiber communication, optical transmission systems, and optical device testing. It works based on the photoelectric effect, that is, when light irradiates a photosensitive element, electrons can be excited to generate a current, which is then converted into a voltage and amplified and processed by an electronic circuit, and finally the measured value of the optical power is displayed in digital form.

[0067] It can be understood that the photodetector in the optical power meter is usually made of semiconductor material, and the energy band structure of the semiconductor will change with temperature. Specifically, temperature change will affect the bandgap width of the semiconductor: when the bandgap width narrows, it will change the absorption and conversion efficiency of the photodetector to light, thereby affecting its ability to convert an optical signal into an electrical signal, and ultimately resulting in a deviation in the measured value of the optical power. Moreover, the electronic circuit in the optical power meter contains various components such as resistors and capacitors, and the parameters of these components will also change with temperature. For example, for a metal resistor, the resistance value usually increases with temperature rise, resulting in an error in the measured value; while the capacitance value of the capacitor may change due to temperature change, causing parameters such as the dielectric constant inside it to change, and inevitably changing the accurate measured value. In addition, the amplifier in the circuit of the optical power meter is also sensitive to temperature; temperature change will affect performance parameters such as the gain and noise factor of the amplifier. When the temperature rises, the gain of the amplifier may decrease, and the noise factor may increase, which will weaken the detection ability of the optical power meter for weak optical signals and reduce the measurement accuracy.

[0068] Therefore, if an existing optical power meter is used, only at the standard temperature is the measured optical power value accurate; this standard temperature is obtained considering the normal operating temperature of each device in the optical power meter. However, in the actual measurement scenario, the optical fiber may be distributed outdoors in the open air or underground in a cold and damp environment. The variable distribution environment of the optical fiber cannot precisely control the on-site temperature. Therefore, it is inevitable to have detection errors when using an existing optical power meter in on-site detection.

[0069] In this embodiment, in detection environments with different temperatures, since the influence on the optical power meter is different, the resulting errors will also vary. In this application, it is necessary to consider being compatible with as many detection environments as possible. Therefore, it is necessary to obtain the detection errors in different detection temperature environments to provide a data basis for adjusting the initial value of the adjustment hole to eliminate the detection errors in the subsequent process.

[0070] Specifically, as Figure 2 shown, obtaining the detection error of the adjustment hole in different detection temperature environments, where the detection error is obtained by the adjustment hole based on a standard optical fiber and a corresponding standard optical power value, includes:

[0071] S121. Preset several detection temperatures;

[0072] In this embodiment, presetting several detection temperatures can adjust the optical power meter at different detection temperatures. Preferably, the preset work in this application includes: presetting several detection temperature values or presetting several detection temperature ranges. Presetting several detection temperature values can facilitate setting accurate temperature values during the detection work, reduce setting errors, and obtain the corresponding detection errors through a preset strategy when obtaining a higher-precision actual temperature value. Presetting several detection temperature ranges can cover all temperature environments belonging to the temperature range, avoiding subsequent chaos and errors caused by the inability to quickly correspond to a single preset detection temperature value due to a higher-precision actual temperature value obtained by an individual high-precision temperature detection instrument.

[0073] Exemplarily, the following introduces the relevant details in the steps of presetting several detection temperature ranges:

[0074] In the experience records in the relevant field, the temperature environment of the optical fiber distribution is between -40 degrees Celsius and 80 degrees Celsius. Therefore, in this embodiment, 120 detection temperature ranges will be preset, where [-40°C, -39°C] is a detection temperature range, and so on.

[0075] S122. Place the optical power meter in each of the detection temperature environments in turn, and set the initial value of each adjustment hole to zero;

[0076] In this embodiment, the optical power meter is placed in turn in each detection temperature environment. Preferably, the optical power meter can be placed in a constant temperature incubator capable of controlling the temperature. If the preset value is the detection temperature, the constant temperature incubator can be set to the corresponding detection temperature value. If the preset value is the detection temperature range, the temperature in the constant temperature incubator can be set to be maintained within the corresponding detection temperature range. It can be understood that the temperature in the environment of the detection temperature range remains unchanged based on this detection temperature range, that is, in this environment, the temperature remains within a small fluctuation within the detection temperature range, but does not exceed or fall below the critical value of the detection temperature range, so that the optical power meter can always be ensured to be in the environment of the detection temperature range.

[0077] In this embodiment, when the optical power meter is placed in environments with different detection temperatures, it may directly affect the initial value in the optical power meter. In order to avoid initial errors, when the optical power meter is placed at each detection temperature, the initial value needs to be set to the corrected zero value to reduce the errors caused by changes in the initial value.

[0078] Exemplarily, when the preset value is the detection temperature range, in order to obtain the detection error in the detection temperature range of [-40°C, -39°C), the temperature of the constant temperature incubator needs to be set to [-40°C, -39°C). After obtaining the relevant data, the detection temperature range of the constant temperature incubator is set to [-39°C, -38°C) to obtain the detection error in the detection temperature range of [-39°C, -38°C). It can be understood that because there is a certain delay in the process of the optical power meter reaching the temperature in the detection temperature range during the change of the detection temperature range, it is necessary to preview the temperature change time suitable for the optical power meter to make the obtained detection error more accurate.

[0079] S123. Detect the standard optical fiber using each of the adjustment holes in turn, and obtain the detected optical power values corresponding to each of the adjustment holes in each detection temperature environment.

[0080] In this embodiment, it can be understood that when the optical power meter measures the standard optical fiber at a non-standard temperature, a large detection error will occur. In this application, it is necessary to record the detected optical power values of the standard optical fiber by each adjustment hole in the optical power meter at different detection temperatures in sequence, so as to provide a data basis for calculating the detection error in the follow-up. Exemplarily, when a preset detection temperature range is set, the specific method is as follows: Set the temperature of the constant temperature chamber to [-40°C, -39°C). After waiting for the time for the temperature of the optical power meter to change, use each detection hole of the optical power meter to measure the standard optical fiber, and obtain the detected optical power values of each detection hole at [-40°C, -39°C). Then set the temperature of the constant temperature chamber to [-39°C, -38°C), and repeat the above steps to obtain the detected optical power values of each detection hole at [-39°C, -38°C). Similarly, the detected optical power values corresponding to 120 detection temperature ranges are obtained correspondingly.

[0081] S124. According to the standard optical power value and the detected optical power value, obtain the detection error corresponding to the corresponding adjustment hole in each detection temperature environment.

[0082] In this embodiment, the detected optical power values obtained by each adjustment hole at each detection temperature are compared with the standard optical power value, and the corresponding detection error is obtained, which can provide necessary adjustment materials for the optical power meter at each detection temperature, so as to minimize the detection error caused by temperature as much as possible, thereby improving the accuracy of detecting the optical power.

[0083] Specifically, the obtaining the detection error corresponding to the corresponding adjustment hole in each detection temperature environment according to the standard optical power value and the detected optical power value includes:

[0084] Calculate the detection difference between the standard optical power value and the detected optical power values corresponding to each adjustment hole in each detection temperature environment, and use the detection difference as the detection error corresponding to the corresponding adjustment hole in the corresponding detection temperature environment.

[0085] In this embodiment, it is necessary to calculate the detection difference between the detection power value corresponding to each adjustment hole at each detection temperature and the standard optical power value, and then record the detection difference as the detection error of the corresponding adjustment hole; specifically, the detection difference is a positive or negative real number; for example, when the preset detection temperature range is obtained, the standard optical power value corresponding to the standard optical fiber is Adb; it is understandable that the standard optical power value can be 0db, and the specific value is set according to the actual detection situation; the detection optical power value measured by a certain adjustment hole of the optical power meter in the detection temperature range of [-40°C, -39°C) is Bdb, then the detection difference obtained according to the standard optical power value and the corresponding detection optical power value is +Cdb, and this detection difference is used as the detection error of this adjustment hole in the detection temperature range environment; and so on, the detection errors of other detection temperature ranges are also obtained accordingly.

[0086] S130. Obtain the actual temperature value of the environment where the optical power meter is located, and confirm the initial value corresponding to the adjustment hole according to the actual temperature value and the detection errors in different detection temperature environments;

[0087] In this embodiment, after obtaining the error of each adjustment hole, the optical power meter can be put into actual detection work; during the actual detection process, it is necessary to obtain the actual temperature value of the environment where the optical fiber to be measured is located, so as to clarify the detection error of each adjustment hole at this actual temperature value, thereby adjusting and confirming the initial value of each adjustment hole and reducing the influence of the detection temperature on the measurement result.

[0088] Specifically, as Figure 3 shown, the confirmation of the initial value corresponding to the adjustment hole according to the actual temperature value and the detection errors in different detection temperature environments includes:

[0089] S131. Match the corresponding detection temperature according to the actual temperature value;

[0090] In this embodiment, obtain the actual temperature value in the on-site detection environment and find the detection temperature that matches this actual temperature value; it is understandable that at an interval of 1 degree Celsius for the optical power meter, the up and down fluctuations of the detection error are very small, and it can be approximately considered that the detection errors of each detection temperature value in the detection temperature range will not change. Therefore, if the preset is the detection temperature value and the obtained actual temperature value is between two detection temperature values, a preset strategy, such as the mathematical method of rounding, can be used to obtain the corresponding detection error; therefore, if the preset is the detection temperature range, the detection error corresponding to the detection temperature range in which the actual temperature value falls is used as the detection error of this actual temperature value, which can directly eliminate the detection error of this actual temperature value, thereby improving the detection accuracy.

[0091] S132. Obtain the detection error corresponding to each adjustment hole according to the matched detection temperature as the current error;

[0092] In this embodiment, since the corresponding detection error has been obtained by the optical power meter at this detection temperature, in the environment of the corresponding actual temperature value, the optical power meter will also have the same error situation. According to the obtained detection error, the current error of this actual temperature value can be correspondingly eliminated.

[0093] S133. Set the initial value of each of the adjustment holes to zero, and use the current error to confirm the initial value of the corresponding adjustment hole.

[0094] In this embodiment, when the optical power meter is placed in an environment of the actual temperature, it may directly affect the initial values of the adjustment holes in the optical power meter. To avoid the initial error, when the optical power meter is normally detecting the optical power, the initial values of the adjustment holes need to be set to the corrected zero value to reduce the error caused by the change of the initial value.

[0095] In this embodiment, the detection error corresponding to this actual temperature has been obtained in step S132. It is necessary to adjust the initial values of the adjustment holes in the optical power meter according to the corresponding detection error to overcome the influence of the error on the detection value. Exemplarily, if the obtained actual temperature is -39.5 degrees Celsius and it falls within the detection temperature range of [-40°C, -39°C) when the preset detection temperature range is set, it can be found by referring that the detection error corresponding to an adjustment hole of the optical power meter is +Cdb. Therefore, the initial value of this adjustment hole is adjusted and confirmed as Cdb, so as to overcome the error that the optical power value detected in the low-temperature environment is too small. The operation in the high-temperature environment is similar to the above and will not be elaborated here.

[0096] Specifically, the optical power meter is provided with a temperature detection component for obtaining the actual temperature value.

[0097] In this embodiment, a temperature detector is provided in the optical power meter, which can detect the actual temperature in the actual detection environment, facilitating subsequent searching for the corresponding detection error to adjust the initial value and improving the detection accuracy of the optical power meter.

[0098] Specifically, each adjustment hole corresponds to a hole number, and the optical power meter stores the association of the hole number corresponding to the adjustment hole, the detection temperature, and the detection error.

[0099] Preferably, a storage chip is built into the optical power meter for storing the correlation between the hole number corresponding to the adjustment hole, the detected temperature, and the detection error. Exemplarily, each hole number corresponds to an error table, which records each detection and the corresponding detection error, and can provide necessary data for adjusting the initial value of each subsequent adjustment hole. As shown in Table 1, when the preset detected temperature range is set, the error table corresponding to hole number 01 can be stored in the following manner:

[0100] Table 1

[0101]

[0102]

[0103] S140. Use the adjustment hole to detect the fiber under test to obtain the detected optical power value of the fiber under test;

[0104] S150. Correct the detected optical power value based on the initial value to obtain the actual optical power value of the fiber under test.

[0105] In this embodiment, the adjusted optical power meter can overcome the detection error caused by the temperature environment, so that the obtained actual optical power value tends to be accurate, can provide reliable optical power data for subsequent inspection and troubleshooting of the optical fiber, and improve the efficiency of inspection and troubleshooting.

[0106] Specifically, as Figure 4 shown, before determining one or more detection holes in the optical power meter as adjustment holes, it further includes initial value correction for each detection hole, which specifically includes the following steps:

[0107] S210. Obtain the standard optical power value of the standard optical fiber and the standard temperature corresponding to the standard optical power value;

[0108] In this embodiment, in order to eliminate the systematic error formed in the manufacturing process of the optical power meter, it is necessary to use the standard optical power value corresponding to the standard optical fiber to correct the initial value of the detection hole of the optical power meter at the corresponding standard temperature.

[0109] S220. Place the optical power meter in an environment of the standard temperature;

[0110] In this embodiment, the standard temperature is obtained through empirical accumulation records or multiple test records, and the standard temperature will correspond to the standard optical fiber one by one. It can be understood that when the optical power meter is placed in a standard temperature environment, the temperature of the standard temperature environment is constant, so that each detection hole in the optical power meter can obtain accurate calibration data. Preferably, the optical power meter can be placed in a constant temperature chamber that can control the temperature.

[0111] S230. Use each detection hole of the optical power meter to detect the standard optical fiber in sequence to obtain corresponding corrected optical power values;

[0112] In this embodiment, due to the differences in the manufacturing processes of each detection hole in the optical power meter, there will inevitably be systematic errors. Therefore, at the standard temperature, the corresponding corrected optical power values measured by each detection hole in the optical power meter for the standard optical fiber are not necessarily equal to the standard optical power value. Therefore, it is necessary to correct the initial values of each detection hole in the optical power meter. It can be understood that it is necessary to use each detection hole to detect the standard optical fiber in sequence. Since the systematic errors of each detection hole are different, the corrected optical power values obtained by detecting the standard optical fiber will also be different. Therefore, it is necessary to record the corrected optical power values obtained by each detection hole detecting the standard optical fiber to ensure that the initial values of each detection hole can be corrected subsequently.

[0113] S240. Calculate the correction difference between each corrected optical power value and the standard optical power value, and correct the initial value of the corresponding detection hole of the optical power meter according to the correction difference.

[0114] In this embodiment, calculate the correction difference between the corrected optical power value and the standard optical power value. This correction difference can reflect the systematic error of each detection hole of the optical power meter; correct the initial value of the corresponding detection hole in the optical power meter with this correction difference. Specifically, increase and decrease the correction difference for the initial value of the detection hole so that the optical power value measured at the standard temperature is equal to the standard optical power value.

[0115] Exemplarily, the standard optical power value corresponding to the standard optical fiber is Adb, and the corrected optical power value measured by a certain detection hole in the optical power meter at the standard temperature is Fdb. Then the correction difference obtained according to the standard optical power value and the corrected optical power value is +Gdb. Therefore, correct the initial value of the corresponding detection hole of the optical power meter at the position of the Gdb value to 0db, so that the optical power value obtained by measuring the standard optical fiber by this detection hole again at the standard temperature is Adb, which is equal to the standard optical power value, thus completing the correction.
