Description

Technical Field

[0001] The present invention relates to the field of optical fiber operation and maintenance technology, and more specifically, to an optical fiber clamping method, an optical fiber matching method, and an optical fiber pairing method and system. Background Art

[0002] Optical fiber is now widely used in a variety of key areas, including communications, internet data transmission, medical equipment, and industrial control, significantly improving the speed and stability of information transmission. However, with the surge in optical fiber usage, management challenges have become increasingly prominent. Numerous racks are used to house optical fibers, and the sheer number of bundled fibers makes it difficult to quickly and accurately locate the same fiber across different racks. To address this issue, fiber alignment has emerged. This process is responsible for accurately identifying and connecting the corresponding fibers within complex optical fiber networks, ensuring stable optical signal transmission. Currently, fiber alignment is not only time-consuming but also presents numerous challenges. Aligning armored optical fibers poses a particular challenge: clamps typically only bend the fiber to a certain degree, and the resulting light leakage power at this degree of bending is unstable, affecting alignment accuracy. Further bending to increase the light leakage power can also damage the fiber. Summary of the Invention

[0003] The present invention aims to overcome at least one defect (shortcoming) of the above-mentioned prior art and provides a fiber clamping method, a fiber matching method and a fiber pairing method and system, which are applied to armored optical fibers to accurately adjust the bending degree of the clamped optical fibers, so that the clamped optical fibers generate accurate light leakage signals, thereby improving the efficiency of fiber patching detection.

[0004] According to a first aspect of the present application, a method for clamping an optical fiber based on a fiber clamping instrument is provided, the method comprising:

[0005] The fiber clamping instrument sets a first trigger threshold;

[0006] The fiber clamping instrument performs a bending operation and a corresponding straightening operation on the optical fiber to be tested, so that the fiber clamping instrument collects the optical signal of the optical fiber to be tested during the bending operation and the straightening operation on the optical fiber to be tested;

[0007] For the bending operation, the fiber clamp monitors the actual light leakage loss value of the optical fiber to be tested at the bending point during the bending operation, and compares the actual light leakage loss value with the first trigger threshold in real time. When the actual light leakage loss value reaches the first trigger threshold, a stop bending signal is generated, the current bending operation is stopped, and the corresponding straightening operation is performed on the optical fiber to be tested.

[0008] It is understandable that the present application presets a first trigger threshold in the fiber clamping instrument, and performs bending operations and corresponding straightening operations on the optical fiber to be tested according to the first trigger threshold, and at the same time, collects the optical signal of the optical fiber to be tested during the bending operation and the straightening operation of the optical fiber to be tested by the fiber clamping instrument, thereby achieving accurate matching of the optical fibers, effectively improving the docking accuracy of the optical fibers, reducing the optical signal loss of the optical fibers, and enhancing the stability of the fiber clamping operation and improving the efficiency of the fiber clamping operation; at the same time, the optical fiber to be tested is bent in accordance with the first trigger threshold, and when the stop bending signal is triggered, the current bending operation is stopped and the straightening operation is started, which can avoid the problem of excessive or insufficient leakage light signals caused by bending the optical fiber to be tested with a fixed bending degree, thereby solving the technical problem that the leakage light signal is too large and affects the normal transmission of the optical fiber to be tested, and the technical problem that the leakage light signal is too small and the fiber clamping instrument cannot obtain the leakage light signal.

[0009] Optionally, the fiber clamping instrument performs a bending operation and a corresponding straightening operation on the optical fiber to be tested, specifically including:

[0010] The fiber clamping instrument performs several bending operations and corresponding number of straightening operations on the optical fiber to be tested. When the bending stop signal is triggered during one of the bending operations, the bending operation is stopped and the corresponding straightening operation is performed on the optical fiber to be tested.

[0011] When the optical fiber to be tested is restored to its original state according to the corresponding straightening operation, the fiber clamping instrument starts the next bending operation on the optical fiber to be tested.

[0012] It is understandable that by performing several bending operations and a corresponding number of straightening operations on the optical fiber to be tested by the fiber clamp, the optical fiber to be tested can generate multiple loss signals, which has the effect of signal flashing. This can avoid loss errors caused by manual touch or pressure from heavy objects on the optical fiber to be tested, as well as accidental errors caused by detection errors of the fiber clamp, which will result in the fiber clamp being unable to accurately collect the loss signals of the optical fiber to be tested, thereby affecting the accuracy of the fiber work.

[0013] Optionally, the bending operation includes: the fiber clamping instrument increases the clamping angle of the optical fiber to be tested at a certain speed, so as to increase the actual light leakage loss value generated by the optical fiber to be tested.

[0014] It is understandable that by precisely controlling the clamping angle of the fiber clamp, the actual light leakage loss value of the optical fiber to be tested due to the bending operation can be increased, thereby ensuring the accuracy and consistency of the loss value management during the fiber clamping process, and ensuring that the fiber clamp obtains a regular loss signal, eliminating the error caused by the accidental touch operation of the optical fiber to be tested during the matching process, and effectively improving the accuracy of the optical fiber matching.

[0015] Optionally, the straightening operation includes: the fiber clamping instrument maintains a certain speed to reduce the clamping angle of the optical fiber to be tested, so as to reduce the actual light leakage loss value generated by the optical fiber to be tested.

[0016] It is understandable that by precisely controlling the clamping angle of the fiber clamp, the actual light leakage loss value of the optical fiber to be tested caused by the straightening operation can be reduced, thereby ensuring the accuracy and consistency of the loss value management during the fiber clamping process, and ensuring that the fiber clamp obtains a regular loss signal, eliminating the error caused by the accidental touch operation of the optical fiber to be tested during the matching process, and effectively improving the accuracy of the optical fiber matching.

[0017] Optionally, the fiber clamping instrument is provided with a detection component for obtaining the actual light leakage loss value.

[0018] It is understandable that by respectively setting up detection components in the fiber clamping instrument, accurate acquisition of the actual light leakage loss value is achieved.

[0019] Optionally, the fiber clamping instrument is provided with an electric drive device for performing the bending operation and the straightening operation on the optical fiber to be tested.

[0020] It is understandable that by respectively arranging electric drive devices in the fiber clamping instrument, accurate bending and straightening operations of the optical fiber to be tested can be achieved.

[0021] According to a second aspect of the present application, a fiber matching method based on a fiber aligner is provided, the method comprising:

[0022] The fiber analyzer presets a second trigger threshold and a matching strategy;

[0023] The fiber pairing instrument collects optical signals of each optical fiber to be paired including the optical fiber to be tested, and extracts corresponding difference loss signals according to the optical signals;

[0024] The fiber pairing instrument determines whether the loss signal is generated by a light leakage signal according to the second trigger threshold and the matching strategy, and if so, determines that the optical fiber to be paired that generates the loss signal is the optical fiber to be tested;

[0025] The light leakage signal is generated when the optical fiber to be tested is bent several times and straightened a corresponding number of times using a fiber clamping instrument using the optical fiber clamping method described in the first aspect of the present application, and the first trigger threshold is equal to the second trigger threshold.

[0026] It is understood that by presetting a second trigger threshold and matching strategy, collecting the optical signal of the optical fiber to be paired to extract the loss signal, and judging whether the loss signal is generated by a leakage signal based on the second trigger threshold and matching strategy, thereby determining whether the optical fiber to be paired is the optical fiber to be tested, this characteristic of the leakage signal can be effectively utilized to accurately identify the optical fiber to be tested. The leakage signal is generated when the optical fiber to be tested is bent and straightened a specific number of times, and the second trigger threshold is set equal to the first trigger threshold in the optical fiber clamping method of the first aspect. This helps to improve the accuracy and efficiency of optical fiber matching, reduce misjudgments, make the entire optical fiber matching process more scientific and reliable, and ensure the smooth implementation of the optical fiber matching work.

[0027] Optionally, the fiber pairing instrument determines whether the loss signal is generated by a light leakage signal according to the second trigger threshold and the matching strategy, and if so, determines that the optical fiber to be paired that generates the loss signal is the optical fiber to be tested, including:

[0028] The fiber analyzer obtains the waveform of the difference loss signal;

[0029] If there are a preset number of uniformly changing waveforms in the waveform of the loss signal and the peak value of each uniformly changing waveform reaches the second trigger threshold, the fiber pairing instrument determines that the loss signal triggers the matching strategy and determines that the optical fiber to be paired that generates the loss signal is the optical fiber to be tested.

[0030] It can be understood that by analyzing the waveform of the loss signal, when there are a preset number of uniformly changing waveforms in the waveform and the peak value of each of the uniformly changing waveforms reaches the second trigger threshold, the loss signal is determined to trigger the matching strategy, and the loss signal is determined to be the loss signal corresponding to the leakage signal, thereby determining that the optical fiber to be paired that generates the loss signal is the optical fiber to be tested; this method can more accurately identify and match the loss signal formed based on the fiber clamping instrument, thereby matching the corresponding optical fiber, and improving the stability and reliability of the matching method.

[0031] According to a third aspect of the present application, a method for optical fiber alignment is provided, the method comprising:

[0032] A first trigger threshold is preset in the fiber clamping instrument, and a second trigger threshold and a matching strategy are preset in the fiber alignment instrument; wherein the first trigger threshold is equal to the second trigger threshold;

[0033] Using the fiber clamping instrument to perform several bending operations on the optical fiber to be tested and performing a corresponding straightening operation after each bending operation based on the first trigger threshold, so that the optical fiber to be tested generates a light leakage signal;

[0034] The fiber pairing instrument is used to collect optical signals of each optical fiber to be paired including the optical fiber to be tested, and corresponding loss signals are extracted according to the optical signals. The loss signal corresponding to the light leakage signal is determined according to the loss signal, the matching strategy and the second trigger threshold. According to the corresponding loss signal, it is determined that the corresponding optical fiber to be paired is the optical fiber to be tested.

[0035] According to a fourth aspect of the present application, a system for optical fiber alignment is provided, the system comprising a fiber clamping instrument and a fiber alignment instrument, wherein:

[0036] The fiber clamping instrument is used to preset a first trigger threshold, perform several bending operations on the optical fiber to be tested, and perform a corresponding straightening operation after each bending operation based on the first trigger threshold, so that the optical fiber to be tested generates a light leakage signal;

[0037] The fiber pairing analyzer is configured to preset a second trigger threshold and a matching strategy, and is configured to connect optical fibers to be paired including the optical fiber to be tested, collect optical signals of the optical fibers to be paired, extract corresponding loss signals based on the optical signals, determine a loss signal corresponding to the light leakage signal based on the loss signal, the matching strategy, and the second trigger threshold, and determine that the corresponding optical fiber to be paired is the optical fiber to be tested based on the corresponding loss signal;

[0038] The first trigger threshold is equal to the second trigger threshold.

[0039] Based on any one of the above aspects, an embodiment of the present application provides a fiber clamping method, a fiber matching method, and a fiber pairing method and system, wherein the fiber clamping instrument sets a first trigger threshold; the fiber clamping instrument performs a bending operation and a corresponding straightening operation on the optical fiber to be tested, so that the fiber pairing instrument collects the optical signal of the optical fiber to be tested during the bending operation and the straightening operation on the optical fiber to be tested; for the bending operation, the fiber clamping instrument monitors the actual light leakage loss value of the optical fiber to be tested at the bend during the bending operation, and compares the actual light leakage loss value with the first trigger threshold in real time. When the actual light leakage loss value reaches the first trigger threshold, a stop bending signal is generated, the current bending operation is stopped, and the corresponding straightening operation is performed on the optical fiber to be tested. The present application can bring the following benefits:

[0040] Improve the precision control of fiber bending: The fiber under test is bent continuously and smoothly so that its bending degree meets the bending degree corresponding to the first trigger threshold. This can avoid the problem of excessive or insufficient leakage signal caused by bending the fiber under test at a fixed bending degree. This solves the technical problem that excessive leakage signal affects the normal transmission of the fiber under test, and the technical problem that insufficient leakage signal makes the fiber analyzer unable to obtain leakage signal, thereby improving the efficiency of fiber patching inspection.

[0041] Improve the docking accuracy of the fiber optic tester and the fiber clamping tester: By setting equal first and second trigger thresholds and bending and straightening the fiber under test, the signals generated at the clamping end and the signal acquisition end of the fiber can be quickly matched, thereby improving docking accuracy.

[0042] Improved matching efficiency: Automating the light leakage signal generation and matching process can improve operational efficiency, reduce the need for manual intervention, and reduce matching errors caused by human error. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] The figures in this application are for illustrative purposes only and are not to be construed as limiting the present application. To better illustrate the following embodiments, some components in the figures may be omitted, enlarged, or reduced in size, and do not represent actual product dimensions. Those skilled in the art will appreciate that some well-known structures and their descriptions may be omitted from the figures.

[0050] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0051] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in a sequence other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0052] With the widespread application and massive demand for optical fiber in fields such as communications, healthcare, and industry, fiber routing has become increasingly complex. When troubleshooting, searching for matching optical fibers can be time-consuming due to the complex fiber routing. In order to improve the efficiency of troubleshooting, fiber alignment has emerged. It uses a fiber clamping instrument to generate differential loss values ​​for optical fibers and uses the fiber alignment instrument at the other end of the fiber to receive the optical signal of the optical fiber, so as to find the same optical fiber at different distribution locations of the optical fiber. Nowadays, the fiber clamping instrument can bend the optical fiber according to a fixed bending degree. This design can reduce the debugging and thinking time of the troubleshooter to a certain extent and improve the efficiency of clamping. However, different optical fibers have different functionalities and correspond to different optical fiber types. In the entire optical fiber distribution system, different types of optical fibers are inevitably selected to adapt to the transmission work. Different types of optical fibers have different physical properties such as thickness, softness and hardness. Furthermore, for the same type of optical fiber, its surface loss is not the same when it is used for different time. Therefore, bending optical fibers with different usage times with the same force and angle may generate different light leakage signals. In summary, different types of optical fibers with different usage times bring many inconveniences to the use of fiber clamping instruments with fixed bending degrees:

[0053] Different types of optical fibers have different thicknesses and degrees of hardness. When clamped by a fiber clamp with a preset bending level, the loss values ​​produced are uncontrollable. Operators may not know how to select the corresponding bending level to produce an appropriate loss value for the optical fiber because they do not understand the thickness, hardness, and / or loss of the optical fiber. If the bending level is too small, the loss value produced is too weak, and the fiber clamp cannot obtain the weak loss value at the other end of the optical fiber, resulting in an inability to match the optical fiber. If the bending level is too high, the loss value produced is too strong, which may affect the normal transmission of the optical fiber. To properly solve the above problems, operators will understand the relevant properties of the optical fiber in advance and select the appropriate bending level through some testing. However, this adds more preparatory work to the fiber work and requires higher technical literacy from the operator, making the fiber work difficult and complicated to operate.

[0054] Due to the above-mentioned problems, existing technologies also have different fiber clamping devices to adapt to different types of optical fibers and different usage times. Different bending levels are set according to the physical properties of each optical fiber to ensure that the optical fiber produces the appropriate loss value. This can solve the problem of uncontrollable loss value to a certain extent, but it will waste a lot of design time and manpower and material resources to replace the fiber clamping device.

[0055] Based on the above-mentioned defects, it is necessary to make necessary improvements to the method of matching optical fibers.

[0056] 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 with reference to the accompanying drawings.

[0057] like Figure 1 As shown, this embodiment provides a fiber clamping method based on a fiber clamping instrument, which can be subdivided into the following steps:

[0058] S110, the fiber clamping instrument sets a first trigger threshold;

[0059] In this embodiment, a first trigger threshold needs to be preset in the fiber clamping instrument. The first trigger threshold reflects the target actual light leakage loss value that needs to be generated after the optical fiber to be tested undergoes a bending operation, so that an appropriately clear loss signal can be normally collected in the fiber clamping instrument, and the loss signal has almost no effect on the normal transmission work of the optical fiber.

[0060] It is understandable that the first trigger threshold can be set equal for optical fibers of different types and different usage times. This is because the first trigger threshold serves as the acquisition basis for the fiber analyzer to find a matching optical fiber. As long as the second trigger threshold of the fiber analyzer remains unchanged, the first trigger threshold generated by optical fibers of different types and different usage times can trigger the second trigger threshold of the fiber analyzer and a matching event. Furthermore, because the loss error that affects optical fiber transmission must meet a certain critical value, when setting the first and second trigger thresholds, it is only necessary to consider that the first and second trigger thresholds are not greater than the critical value to meet the condition of not affecting normal optical fiber transmission. Specifically, the first trigger threshold is equal to the second trigger threshold.

[0061] S120: The fiber clamping instrument performs a bending operation and a corresponding straightening operation on the optical fiber to be tested, so that the fiber clamping instrument collects an optical signal of the optical fiber to be tested during the bending operation and the straightening operation;

[0062] As you can understand, a fiber clamp provides precise control over the fixation and bending of optical fibers. It typically features adjustable clamping components that adjust flexibly to the fiber's outer diameter, ensuring that the fiber is neither damaged by overtightening nor slipped by being too loose. Furthermore, the clamp features a precise bend control mechanism, applying force to the fiber at a preset angle to achieve stable bending. This creates a loss signal due to light leakage caused by the bending. This loss signal affects the power properties of the entire fiber, so corresponding loss signals can also be detected at other locations along the fiber.

[0063] In this embodiment, the fiber clamping instrument of the present application can realize the bending operation and the corresponding straightening operation of the optical fiber to be tested; different from the fixed-level bending in the prior art, the fiber clamping instrument of the present application does not need to set the bending degree of the optical fiber to be tested and the corresponding bending angle in advance, but only needs to preset a first trigger threshold. During the bending operation, the clamping angle of the optical fiber can be continuously adjusted according to the physical properties of the optical fiber, so that the optical fiber to be tested is regularly bent until the light leakage loss value caused by the bending reaches the first trigger threshold. Moreover, the fiber clamping instrument of the present application can perform a straightening operation on the optical fiber to be tested after the actual light leakage loss value caused by the bending of the optical fiber to be tested reaches the first trigger threshold, so that the optical fiber to be tested can return to its original state, ensuring that the original state is restored after the next bending operation or the clamping work is stopped.

[0064] In this embodiment, each time an optical fiber is bent, an actual light leakage loss value is constantly acquired and compared with a first trigger threshold in real time to obtain a signal to stop bending. If the actual light leakage loss value is less than the first trigger threshold, it indicates that the actual light leakage loss value resulting from the bending operation is insufficient for the fiber analyzer to properly identify, and therefore the bending depth needs to be increased. If the actual light leakage loss value is equal to the first trigger threshold, it indicates that the actual light leakage loss value resulting from the bending operation is sufficient for the fiber analyzer to properly identify and does not affect normal transmission of the optical fiber, and therefore the bending depth can be stopped from being increased. It is understood that in actual comparison operations, the actual light leakage loss value can be compared with the first trigger threshold every time the actual light leakage loss value increases by a certain decibel, thereby minimizing the possibility that the actual light leakage loss value exceeds the first trigger threshold due to excessive bending, which could affect normal transmission of the optical fiber.

[0065] Specifically, during the bending operation, the fiber clamp monitors the actual light leakage loss value of the optical fiber under test at the bend, compares the actual light leakage loss value with the first trigger threshold in real time, and generates a stop bending signal when the actual light leakage loss value reaches the first trigger threshold, thereby stopping the bending operation and performing a corresponding straightening operation on the optical fiber under test. In this embodiment, the fiber clamp is clamped at one end of the optical fiber under test.

[0066] For example, an operator finds an optical fiber to be tested that needs to be repaired or checked in a certain rack, and needs to obtain the specific location of the optical fiber to be tested in another rack. It is understandable that because a large number of optical fibers are placed in the racks in the entire optical fiber arrangement, and many optical fibers are stored in bundles due to storage needs, in order to identify the optical fiber to be tested that needs to be checked, it is necessary to use some fiber alignment tools to quickly locate the optical fiber to be tested. Therefore, a fiber clamp is required to generate a light leakage signal at the identifiable end of the optical fiber to be tested. The fiber alignment tool obtains the loss signal of each optical fiber to be paired on the racks containing the optical fibers to be tested, until the loss signal corresponding to the light leakage signal generated by the bending operation and the straightening operation is found, and then the optical fiber to be tested that needs to be found can be matched.

[0067] In this embodiment, when the fiber clamp begins to perform a bending operation on the optical fiber to be tested, the bending angle of the optical fiber to be tested by the fiber clamp continuously increases, so that the actual light leakage loss value generated by the optical fiber to be tested continuously increases. It is understandable that for some optical fibers to be tested that have been in use for a long time, before the fiber clamp is bent, the initial light leakage loss value may not be 0 due to the loss of the surface protective layer. When the fiber clamp is performing a bending operation on the optical fiber, it is necessary to superimpose on the initial light leakage loss value. If the initial light leakage loss value is greater than or equal to the first trigger threshold, indicating that the surface loss of the optical fiber may have a risk of affecting normal transmission work, a warning can be issued and subsequent maintenance work can be awaited. Since the maintenance work is not the focus of this application, it will not be described here.

[0068] Specifically, the fiber clamping instrument performs a bending operation and a corresponding straightening operation on the optical fiber to be tested, specifically including:

[0069] The fiber clamping instrument performs several bending operations and corresponding number of straightening operations on the optical fiber to be tested. When the bending stop signal is triggered during one of the bending operations, the bending operation is stopped and the corresponding straightening operation is performed on the optical fiber to be tested.

[0070] When the optical fiber to be tested is restored to its original state according to the corresponding straightening operation, the fiber clamping instrument starts the next bending operation on the optical fiber to be tested.

[0071] In this embodiment, a single bending operation on the optical fiber to be tested may generate a light leakage signal sporadically. In order to avoid accidental errors in light leakage signals caused by artificial squeezing of the optical fiber or squeezing by heavy objects, as well as accidental data acquisition errors of the fiber analyzer, it is necessary to perform several bending operations and a corresponding number of straightening operations on the optical fiber to be tested, so as to achieve a regular signal flickering effect and reduce accidental errors.

[0072] Specifically, the bending operation includes: the fiber clamping instrument increases the clamping angle of the optical fiber to be tested at a certain speed, so as to increase the actual light leakage loss value generated by the optical fiber to be tested.

[0073] In this embodiment, the fiber clamp increases the bending angle of the fiber under test at a constant rate. Understandably, the angle increased per unit time varies for different types of optical fibers, because the actual light leakage loss values ​​generated at the same bending angle will vary for optical fibers of varying thicknesses or types. However, for optical fibers of varying thicknesses or types, the fiber clamp has a single goal: to continuously change the degree of bending of the fiber, causing the actual light leakage loss value to continuously change until it reaches a first trigger threshold. Preferably, the speed at which the fiber clamp changes the clamping angle of the fiber under test can be adjusted so that the actual light leakage loss value of the fiber under test increases at a uniform rate, thereby generating a uniform loss signal that facilitates subsequent identification and matching.

[0074] Specifically, the straightening operation includes: the fiber clamping instrument maintains a certain speed to reduce the clamping angle of the optical fiber to be tested, so as to reduce the actual light leakage loss value generated by the optical fiber to be tested.

[0075] In this embodiment, similarly, after the actual light leakage loss value reaches the first trigger threshold, it is necessary to reduce the clamping angle of the fiber clamp on the optical fiber to be tested at a certain speed so that the actual light leakage loss value generated by the optical fiber to be tested can be continuously reduced; preferably, the speed at which the fiber clamp changes the clamping angle of the optical fiber to be tested can be adjusted so that the actual light leakage loss value of the optical fiber to be tested can be uniformly reduced, thereby generating a uniform loss signal, which is beneficial for subsequent identification and matching. Combined with the above-mentioned characteristics of bending and straightening the optical fiber to be tested, the clamping angle of the optical fiber to be tested can be controlled so that the actual light leakage loss value generated by the optical fiber is continuously changing, thereby causing the loss signal obtained by the fiber clamp to continuously change, so that when the loss signal is converted into a visual graph, it is a regular waveform image. Because it is difficult to achieve regular changes in the actual light leakage loss value of the optical fiber to be tested when manually touching and squeezing the optical fiber, this design can avoid manual interference to a certain extent.

[0076] Specifically, the fiber clamping instrument is provided with a detection component for obtaining the actual light leakage loss value.

[0077] In this embodiment, the fiber clamping instrument is provided with a detection component that can constantly detect the actual light leakage loss value of the optical fiber; preferably, the detection component is a detection probe provided on the fiber clamping instrument close to the optical fiber to be tested.

[0078] Specifically, the fiber clamping instrument is provided with an electric drive device for performing the bending operation and the straightening operation on the optical fiber to be tested.

[0079] In this embodiment, the fiber clamping instrument is provided with an electric drive device, which can perform regular bending and straightening operations on the optical fiber to be tested, so that the optical fiber to be tested can generate a regular loss signal.

[0080] like Figure 2 As shown, the embodiment of the present application also provides a fiber matching method based on a fiber optic instrument, and the method may include the following steps:

[0081] S210, presetting a second trigger threshold and a matching strategy for the fiber analyzer;

[0082] In this embodiment, a second trigger threshold needs to be preset in the fiber alignment instrument, and the second trigger threshold needs to be equal to the first trigger threshold of the fiber clamping instrument. This allows the fiber clamping instrument to bend the optical fiber with an appropriate actual light leakage loss value as the target, generating an appropriate light leakage signal, thereby avoiding abnormal problems caused by insufficient or excessive bending of the optical fiber. At the same time, it also ensures that the light leakage signal generated by the bending and straightening operation of the optical fiber to be tested according to the first trigger threshold can be triggered by the second trigger threshold in the fiber alignment instrument and identified, so that the corresponding optical fiber to be tested can be found in the fiber alignment instrument. The preset matching strategy can provide a matching basis for the fiber alignment, and match the optical fiber to be tested with the second trigger threshold, thereby improving the efficiency and accuracy of matching.

[0083] S220, the fiber pairing instrument collects optical signals of each optical fiber to be paired including the optical fiber to be tested, and extracts corresponding loss signals according to the optical signals;

[0084] It is understandable that a fiber aligner is an advanced fiber identification and positioning device, and its principle is based on the precise analysis and comparison of optical fiber signals. When it is necessary to find or identify the optical fiber to be tested, the fiber aligner needs to be placed in the optical fiber set of the optical fibers to be paired. By capturing the optical signal of each optical fiber to be paired, the processing system inside the fiber aligner will quickly analyze the captured optical signal to obtain the differential loss signal corresponding to each optical fiber to be paired. By comparing the characteristic parameters of the differential loss signal such as wavelength, intensity, phase, etc., it can accurately determine which optical fiber to be paired is the optical fiber to be tested. It is understandable that the fiber aligner and the fiber aligner work together to form an indispensable and important part of the fiber alignment work in the optical fiber communication system.

[0085] In this embodiment, the fiber optic analyzer includes multiple detection holes, which are used to connect the receiving ends of multiple optical fibers to be paired, so as to obtain corresponding optical signals. It can be understood that each detection hole in the fiber optic analyzer detects the optical signal of each optical fiber to be paired, and the difference loss signal corresponding to each optical fiber to be paired can be obtained based on the optical signal of each optical fiber to be paired, so as to determine whether the optical fiber to be paired is the optical fiber to be tested. Because for optical fibers that have not been bent or straightened, only slight transmission difference loss can be obtained at the receiving end of the optical fiber to be paired, and there is no uniform and regular difference loss signal generated by the fiber clamping analyzer, it is necessary to extract the difference loss signal of each optical fiber to be paired to obtain the basis for matching the optical fiber to be tested.

[0086] S230. The fiber pairing instrument determines whether the loss signal is generated by a light leakage signal based on the second trigger threshold and the matching strategy. If so, the optical fiber to be paired that generates the loss signal is determined to be the optical fiber to be tested; wherein the light leakage signal is generated when the optical fiber to be tested is subjected to several bending operations and a corresponding number of straightening operations using the above-mentioned optical fiber clamping method and the fiber clamping instrument, and the first trigger threshold is equal to the second trigger threshold.

[0087] In this embodiment, the fiber optic analyzer obtains the corresponding optical signal for each optical fiber to be paired in turn in the optical fiber set to be paired that includes the optical fiber to be tested, and extracts the corresponding difference loss signal based on the optical signal; if the difference loss signal of a certain optical fiber to be paired corresponds one-to-one with the light leakage signal generated by the fiber optic clamping analyzer, then the optical fiber to be paired is the optical fiber to be tested, thereby obtaining the specific position of the optical fiber to be tested in another rack or another arrangement point.

[0088] Specifically, if Figure 3 As shown, the fiber pairing instrument determines whether the loss signal is generated by a light leakage signal according to the second trigger threshold and the matching strategy, and if so, determines that the optical fiber to be paired that generates the loss signal is the optical fiber to be tested, including the following steps:

[0089] S231, the fiber analyzer obtains the waveform of the difference loss signal;

[0090] In this embodiment, the acquired loss signal can be displayed as a visual waveform image;

[0091] S232. If the waveform of the loss signal includes a preset number of uniformly varying waveforms and the peak value of each uniformly varying waveform reaches the second trigger threshold, the fiber pairing analyzer determines that the loss signal triggers the matching strategy and determines that the optical fiber to be paired that generates the loss signal is the optical fiber to be tested.

[0092] In this embodiment, the optical fiber to be tested is clamped by the fiber clamping instrument based on several bending and straightening operations, and the resulting differential loss signal is normally an image with several uniform and symmetrical waveforms, and the peak value of each uniformly changing waveform is equal to the second trigger threshold; taking into account the accidental reception error of the fiber clamping instrument, it is set as a matching strategy if there are a preset number of uniformly changing waveforms and the peak value of each of the uniformly changing waveforms reaches the second trigger threshold. When the differential loss signal can trigger the matching strategy, it is determined that the optical fiber to be paired that generates the differential loss signal is the optical fiber to be tested.

[0093] In this embodiment, the optical fiber to be paired is determined to be the optical fiber to be tested based on the corresponding difference loss signal, which can avoid human error in touching and accidental reception errors in the fiber pairing work, improve the accuracy and recognition efficiency of the fiber pairing work, and ensure the smooth progress of the fiber pairing work.

[0094] Preferably, the fiber clamping instrument is placed at several rack positions of the optical fiber to be tested and generates several light leakage signals thereto, and at the same time receives loss signals at the optical fiber to be paired, and the routing status of the optical fiber to be tested is obtained through the loss signals received by the fiber clamping instrument and the corresponding generation positions.

[0095] It is understandable that optical fibers can be arranged on multiple floors or in different buildings, and there may be spatial limitations for obtaining their specific arrangement routes. The method of the present application can also be applied to the field of obtaining the accurate routing direction of optical fibers. After obtaining the specific position of the optical fiber to be tested in a single optical fiber storage area, a fiber clamping instrument is placed and clamped at multiple specific positions on the optical fiber to generate differential loss signals at several different positions. The fiber clamping instrument can obtain the specific positions of the optical fiber to be tested by determining whether it can receive the differential loss signal at that position, thereby obtaining the global distribution of the optical fiber to be tested.

[0096] It is understandable that a communication component can be built into the fiber optic instrument to obtain the specific position of each fiber optic clamp through this communication component, and add location information to the differential loss signal received by the fiber optic instrument, so as to quickly obtain the routing direction of the optical fiber to be tested; preferably, the communication component can be a Bluetooth component or other wireless communication module that can transmit over longer distances.

[0097] like Figure 4 As shown, the embodiment of the present application also provides a method for optical fiber alignment, which may include the following steps:

[0098] S310: Preset a first trigger threshold in the fiber clamping instrument, and preset a second trigger threshold and a matching strategy in the fiber alignment instrument; wherein the first trigger threshold is equal to the second trigger threshold;

[0099] S320, using the fiber clamping instrument to perform several bending operations on the optical fiber to be tested and performing a corresponding straightening operation after each bending operation based on the first trigger threshold, so that the optical fiber to be tested generates a light leakage signal;

[0100] S330. Utilize the fiber pairing instrument to collect optical signals of each optical fiber to be paired, including the optical fiber to be tested, and extract corresponding loss signals based on the optical signals; determine the loss signal corresponding to the light leakage signal based on the loss signal, the matching strategy, and the second trigger threshold; and determine that the corresponding optical fiber to be paired is the optical fiber to be tested based on the corresponding loss signal.

[0101] Based on this embodiment, a method for optical fiber alignment is proposed, which can use a fiber clamp to achieve the effect of electric bending of the optical fiber to be tested, so that for optical fibers of different types and different usage times, appropriate actual leakage loss values ​​are generated under the clamping of the fiber clamp, ensuring normal reception of the fiber clamp; at the same time, the fiber clamp is simple to operate, and the operator only needs to clamp the fiber clamp on the optical fiber to be tested, and the operator does not need to operate again. The clamping angle of the optical fiber to be tested is executed by the internal program of the fiber clamp, freeing the operator's hands and improving the efficiency of fiber clamping and alignment.

[0102] like Figure 5 As shown, an embodiment of the present application further provides a system for optical fiber alignment, the system comprising a fiber clamping instrument and a fiber alignment instrument, wherein:

[0103] The fiber clamping instrument is used to preset a first trigger threshold, perform several bending operations on the optical fiber to be tested, and perform a corresponding straightening operation after each bending operation based on the first trigger threshold, so that the optical fiber to be tested generates a light leakage signal;

[0104] The fiber pairing analyzer is configured to preset a second trigger threshold and a matching strategy, and is configured to connect optical fibers to be paired including the optical fiber to be tested, collect optical signals of the optical fibers to be paired, extract corresponding loss signals based on the optical signals, determine a loss signal corresponding to the light leakage signal based on the loss signal, the matching strategy, and the second trigger threshold, and determine that the corresponding optical fiber to be paired is the optical fiber to be tested based on the corresponding loss signal;

[0105] The first trigger threshold is equal to the second trigger threshold.
