Abstract
Description
Technical Field
[0001] This invention relates to the field of optical fiber operation and maintenance technology, and more specifically, to optical fiber clamping methods, optical fiber matching methods, and methods and systems for optical fiber pairing. Background Technology
[0002] Currently, optical fiber is widely used in many key fields such as communications, internet data transmission, medical equipment, and industrial control, greatly improving the speed and stability of information transmission. However, with the surge in optical fiber usage, management issues 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 in different racks. To address this problem, fiber pairing has emerged, primarily responsible for accurately identifying and connecting corresponding optical fibers in complex optical fiber networks to ensure stable optical signal transmission. Today, fiber pairing not only consumes a significant amount of time but also faces numerous challenges; among them, pairing armored optical fibers has become a major difficulty: because clamps can typically only bend the fiber to a certain degree, the leakage power generated by armored optical fibers at this degree of bending is unstable, affecting the accuracy of pairing. However, increasing the bending degree to increase leakage power can easily damage the fiber. Summary of the Invention
[0003] The present invention aims to overcome at least one defect (deficiency) of the prior art and provides an optical fiber clamping method, an optical fiber matching method, and an optical fiber pairing method and system, which are applied to armored optical fibers. The invention accurately adjusts the bending degree of the clamped optical fiber, thereby enabling the clamped optical fiber to generate a precise leakage light signal and improving the efficiency of optical fiber jumper detection.
[0004] According to a first aspect of this application, a fiber optic clamping method based on a fiber clamping device is provided, the method comprising:
[0005] The fiber clamping device is set to a first trigger threshold;
[0006] The fiber clamping device performs bending and straightening operations on the fiber under test, so that the fiber clamping device can collect the optical signal of the fiber under test during the bending and straightening operations.
[0007] During the bending operation, the fiber clamping device monitors the actual light leakage difference value of the optical fiber under test at the bending point, compares the actual light leakage difference value with the first trigger threshold in real time, and when the actual light leakage difference value reaches the first trigger threshold, triggers a stop bending signal to stop the current bending operation and performs a corresponding straightening operation on the optical fiber under test.
[0008] Understandably, this application achieves precise fiber matching by presetting a first trigger threshold in the fiber clamping device and performing bending and straightening operations on the fiber under test according to the first trigger threshold. Simultaneously, the fiber clamping device collects the optical signal of the fiber under test during the bending and straightening operations, effectively improving fiber splicing accuracy, reducing optical signal loss, enhancing the stability of the fiber clamping operation, and increasing its efficiency. Furthermore, by performing bending operations on the fiber under test in conjunction with the first trigger threshold and stopping the current bending operation and initiating the straightening operation when a stop bending signal is generated, the application avoids the problem of excessive or insufficient light leakage signal caused by bending the fiber under test at a fixed degree of curvature. This solves the technical problems of excessive light leakage signal affecting the normal transmission of the fiber under test and insufficient light leakage signal preventing the fiber clamping device from acquiring the light leakage signal.
[0009] Optionally, the fiber clamping device performs bending operations and corresponding straightening operations on the optical fiber under test, specifically including:
[0010] The fiber clamping device performs several bending operations and corresponding straightening operations on the optical fiber under test. When the stop bending 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 under test.
[0011] Once the fiber under test has returned to its original state according to the corresponding straightening operation, the fiber clamping device initiates the next bending operation on the fiber under test.
[0012] Understandably, by performing several bending operations and corresponding straightening operations on the fiber under test using a fiber clamping device, multiple differential loss signals can be generated in the fiber under test, resulting in a signal flashing effect. This can avoid differential loss errors caused by accidental human touch or pressure from heavy objects, as well as accidental errors in the fiber clamping device's detection, which would prevent the device from accurately acquiring the differential loss signal of the fiber under test, thus affecting the accuracy of the fiber clamping operation.
[0013] Optionally, the bending operation includes: the fiber clamping device increasing the clamping angle of the fiber under test at a certain speed, so as to increase the actual light leakage difference value generated by the fiber under test.
[0014] Understandably, by precisely controlling the clamping angle of the fiber clamping device, the actual light leakage loss value of the fiber under test based on the bending operation can be increased, thereby ensuring the accuracy and consistency of loss value management during fiber clamping, and ensuring that the fiber clamping device obtains a regular loss signal, eliminating errors caused by accidental contact with the fiber under test during the matching process, and effectively improving the accuracy of fiber matching.
[0015] Optionally, the straightening operation includes: the fiber clamping device maintaining a certain speed to reduce the clamping angle of the fiber under test, so as to reduce the actual light leakage difference value generated by the fiber under test.
[0016] Understandably, by precisely controlling the clamping angle of the fiber clamper, the actual light leakage loss value of the fiber under test based on the straightening operation can be reduced, thereby ensuring the accuracy and consistency of loss value management during fiber clamping, and ensuring that the fiber clamper obtains a regular loss signal, eliminating errors caused by accidental contact with the fiber under test during the matching process, and effectively improving the accuracy of fiber matching.
[0017] Optionally, the fiber clamping device is equipped with a detection component for obtaining the actual light leakage difference value.
[0018] Understandably, by setting up detection components in the fiber clamping device, the actual light leakage difference value can be accurately obtained.
[0019] Optionally, the fiber clamping device is equipped with an electric drive for performing the bending operation and the straightening operation on the fiber under test.
[0020] Understandably, by setting up electric drive devices in the fiber clamping machine, accurate bending and straightening operations of the fiber under test can be achieved.
[0021] According to a second aspect of this application, a fiber optic matching method based on a fiber optic instrument is provided, the method comprising:
[0022] The fiber optic device is preset with a second trigger threshold and a matching strategy;
[0023] The fiber pairing instrument collects optical signals from each pairing fiber containing the fiber under test, and extracts the corresponding differential loss signal based on the optical signal;
[0024] The fiber pairing instrument determines whether the difference signal is a light leakage signal based on the second trigger threshold and the matching strategy. If so, it determines that the fiber to be paired that generates the difference signal is the fiber to be tested.
[0025] The light leakage signal is generated when the fiber under test is bent and straightened a number of times using a fiber clamping device with the fiber clamping method described in the first aspect of this application, and the first trigger threshold is equal to the second trigger threshold.
[0026] Understandably, by setting a second trigger threshold and matching strategy, and collecting the optical signal of the fiber to be paired to extract the loss signal, the system determines whether the loss signal is generated by a leakage signal based on the second trigger threshold and matching strategy. This allows for the accurate identification of the fiber under test by effectively utilizing the leakage signal characteristic. The leakage signal is generated when the fiber under test undergoes a specific number of bending and straightening operations. Furthermore, the setting of the second trigger threshold is equal to the first trigger threshold in the fiber clamping method described in the first aspect. This helps improve the accuracy and efficiency of fiber matching, reduces misjudgments, and makes the entire fiber matching process more scientific and reliable, ensuring the smooth progress of fiber matching work.
[0027] Optionally, the fiber pairing instrument determines whether the difference loss signal is a leakage signal based on the second trigger threshold and the matching strategy. If so, it determines that the fiber to be paired that generated the difference loss signal is the fiber to be tested, including:
[0028] The waveform of the differential loss signal acquired by the fiber optic cable;
[0029] If, in the waveform of the difference loss signal, there is a preset number of uniformly changing waveforms and the peak value of each uniformly changing waveform reaches the second trigger threshold, then the fiber pairing instrument determines that the difference loss signal triggers the matching strategy and identifies the fiber to be paired that generated the difference loss signal as the fiber to be tested.
[0030] Understandably, by analyzing the waveform of the differential loss signal, when there are a preset number of uniformly changing waveforms and the peak value of each uniformly changing waveform reaches the second trigger threshold, the differential loss signal is determined to trigger the matching strategy, and the differential loss signal is identified as the differential loss signal corresponding to the leakage light signal, thereby determining that the optical fiber to be paired that generated the differential loss signal is the optical fiber to be tested. This method can more accurately identify and match the differential loss signal formed by the fiber clamping device, thereby matching the corresponding optical fiber and improving the stability and reliability of the matching method.
[0031] According to a third aspect of this application, a method for optical fiber-to-fiber pairing is provided, the method comprising:
[0032] A first trigger threshold is preset in the fiber clamping device, and a second trigger threshold and matching strategy are preset in the fiber pairing device; wherein the first trigger threshold is equal to the second trigger threshold;
[0033] The fiber under test is subjected to several bending operations using the fiber clamping device and a corresponding straightening operation is performed after each bending operation based on the first trigger threshold, so that the fiber under test generates a light leakage signal.
[0034] The optical signal of each optical fiber to be paired, which contains the optical fiber under test, is collected by the fiber pairing instrument, and the corresponding difference loss signal is extracted according to the optical signal. The difference loss signal corresponding to the leakage signal is determined according to the difference loss signal, the matching strategy and the second trigger threshold. The corresponding optical fiber to be paired is determined as the optical fiber under test according to the corresponding difference loss signal.
[0035] According to a fourth aspect of this application, a fiber-to-fiber system is provided, the system comprising a fiber clamping device and a fiber-to-fiber pairing device, wherein:
[0036] The fiber clamping device is used to preset a first trigger threshold, and to perform several bending operations on the fiber under test and to perform a corresponding straightening operation after each bending operation based on the first trigger threshold, so that the fiber under test generates a light leakage signal.
[0037] The fiber pairing instrument is used to preset a second trigger threshold and a matching strategy, and to connect each pairing fiber containing the fiber under test, collect the optical signal of the pairing fiber, extract the corresponding differential loss signal based on the optical signal, determine the differential loss signal corresponding to the leakage signal based on the differential loss signal, the matching strategy and the second trigger threshold, and determine the corresponding pairing fiber as the fiber under test based on the corresponding differential loss signal.
[0038] The first trigger threshold is equal to the second trigger threshold.
[0039] Based on any of the above aspects, embodiments of this application provide an optical fiber clamping method, an optical fiber matching method, and an optical fiber pairing method and system. The fiber clamping device sets a first trigger threshold. The fiber clamping device performs a bending operation and a corresponding straightening operation on the optical fiber under test, so that the pairing device collects the optical signal of the optical fiber under test during the bending and straightening operations. For the bending operation, the fiber clamping device monitors the actual light leakage loss value of the optical fiber under test at the bending point during the bending operation, compares the actual light leakage loss value with the first trigger threshold in real time, and when the actual light leakage loss value reaches the first trigger threshold, triggers a stop bending signal, stops the current bending operation, and performs a corresponding straightening operation on the optical fiber under test. This application can bring the following benefits:
[0040] • Improved precision control of fiber optic bending: The fiber under test is bent continuously and smoothly, so that the degree of bending matches the degree of bending corresponding to the first trigger threshold. This avoids the problem of excessive or insufficient leakage signal caused by bending the fiber under test with a fixed degree of bending. This solves the technical problem of excessive leakage signal affecting the normal transmission of the fiber under test, and the technical problem of insufficient leakage signal causing the fiber optic instrument to be unable to obtain the leakage signal, thereby improving the efficiency of fiber optic patching inspection.
[0041] • Improve the docking accuracy of fiber optic clamping and fiber clamping devices: By setting equal first and second trigger thresholds and performing bending and straightening operations on the fiber under test, the signals generated at the clamping end and signal acquisition end of the fiber can be quickly matched, thereby improving the docking accuracy.
[0042] • Improved matching efficiency: Automated light leakage signal generation and matching processes can improve operational efficiency, reduce the need for manual intervention, and reduce matching errors caused by human error. Attached Figure Description

To better illustrate the following embodiments, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product; it is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.
[0050] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.
[0051] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.
[0052] With the widespread application and massive demand for optical fiber in various fields such as communications, healthcare, and industry, the distribution of optical fiber routes has become increasingly complex. During troubleshooting, the complex distribution of optical fiber routes makes finding a matching fiber optic cable time-consuming. To improve troubleshooting efficiency, fiber clamping techniques have emerged. These techniques use a fiber clamping device to generate a differential loss value for the optical fiber and then use the same device at the other end to receive the optical signal, thus locating the same fiber at different distribution locations. Nowadays, fiber clamping devices can bend fibers to a fixed degree, which reduces the debugging and thinking time for troubleshooters and improves clamping efficiency. However, different optical fibers have different functionalities, resulting in different fiber types. In the entire fiber optic distribution system, different types of fibers will inevitably be selected to adapt to transmission needs. Different types of fibers differ in physical properties such as thickness and stiffness. Furthermore, even for the same type of fiber, the surface loss varies with usage time. Therefore, bending fibers with different usage times at the same force and angle may result in different leakage signals. In summary, different types of fibers and different usage times bring many inconveniences to the use of fiber clamping devices with fixed bending degrees.
[0053] Different types of optical fibers, due to their varying thickness and stiffness, produce uncontrollable differential loss values when clamped by a fiber clamping device with a preset bending level. Operators may not know how to select the appropriate bending level to achieve a suitable differential loss value because they are unfamiliar with the fiber's thickness and / or stiffness and / or loss level. If the bending level is too small, the resulting differential loss value will be too weak, and the fiber clamping device will not be able to obtain a weak differential loss value at the other end of the fiber, resulting in failure to match the fiber. If the bending level is too large, the resulting differential loss value will be too strong, which may affect the normal transmission operation of the fiber. To properly solve the above problems, operators will understand the relevant properties of the fiber in advance and select an appropriate bending level through some testing work. However, this adds more preparatory work for fiber clamping and requires higher technical skills from the operators, making fiber clamping operation difficult and complex.
[0054] Due to the aforementioned issues, existing technologies also employ 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 a suitable differential loss value. This can solve the problem of uncontrollable differential loss value to a certain extent, but it wastes a lot of design time and manpower and resources to replace the fiber clamping device.
[0055] Based on the aforementioned shortcomings, necessary improvements need to be made to the method of matching optical fibers.
[0056] This embodiment provides a technical solution that can solve the above problems. The specific implementation of this application will be described in detail below with reference to the accompanying drawings.
[0057] like Figure 1 As shown, this embodiment provides an optical fiber clamping method based on a fiber clamping device, which can be further divided into the following steps:
[0058] S110, The fiber clamping device is set to a first trigger threshold;
[0059] In this embodiment, a first trigger threshold needs to be preset in the fiber clamping device. The first trigger threshold reflects the actual light leakage difference value that needs to be generated after the fiber under test is bent, so that the fiber clamping device can normally collect an appropriate and clear difference signal, and the difference signal has almost no impact on the normal transmission of the fiber.
[0060] Understandably, the first trigger threshold can be the same for different types of optical fibers under test and those used for different durations. This is because the first trigger threshold serves as the basis for the fiber optic instrument to find a matching fiber. As long as the second trigger threshold of the instrument remains unchanged, different types of optical fibers with different usage durations will generate corresponding first trigger thresholds, triggering the second trigger threshold and matching event of the instrument. Furthermore, since the differential loss error affecting optical fiber transmission needs to 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 this critical value to meet the condition of not affecting the normal transmission of the optical fiber. Specifically, the first trigger threshold is equal to the second trigger threshold.
[0061] S120. The fiber clamping device performs a bending operation and a corresponding straightening operation on the fiber under test, so that the fiber clamping device collects the optical signal of the fiber under test during the bending operation and the straightening operation.
[0062] Understandably, fiber clamping devices provide precise control over the fixing and bending of optical fibers. They are typically equipped with adjustable clamping components that can be flexibly adjusted according to the fiber's outer diameter, ensuring that the fiber is neither damaged due to excessive tightness nor slips off due to excessive looseness during clamping. Simultaneously, the fiber clamping device also possesses a precise bending control mechanism. By applying force to the fiber at a preset angle, it achieves stable bending of the fiber, causing light leakage and generating a differential loss signal due to the bending. This differential loss signal affects the power properties of the entire fiber, so the corresponding differential loss signal can also be detected at other locations along the fiber.
[0063] In this embodiment, the fiber clamping device of this application can perform bending operations and corresponding straightening operations on the fiber under test. Unlike the fixed-degree bending of the prior art, the fiber clamping device of this application does not need to pre-set the bending degree and corresponding bending angle of the fiber under test. It only needs to preset a first trigger threshold. During the bending operation, it can continuously adjust the clamping angle according to the physical properties of the fiber, so that the fiber under test is bent regularly until the light leakage loss value caused by bending reaches the first trigger threshold. Moreover, the fiber clamping device of this application can perform a straightening operation on the fiber under test after the actual light leakage loss value caused by bending reaches the first trigger threshold, so that the fiber under test can return to its original state, ensuring that it returns to its original state after the next bending operation or after stopping the clamping work.
[0064] In this embodiment, each time the optical fiber is bent, the actual light leakage loss value needs to be constantly acquired and compared with a first trigger threshold in real time to obtain a stop bending signal. When the actual light leakage loss value is less than the first trigger threshold, it indicates that the actual light leakage loss value generated by the bending degree of the current bending operation is insufficient to be normally identified by the fiber alignment instrument, so the bending degree needs to be increased. When the actual light leakage loss value is equal to the first trigger threshold, it indicates that the actual light leakage loss value generated by the bending degree of the current bending operation is sufficient to be normally identified by the fiber alignment instrument and does not affect the normal transmission operation of the optical fiber, so the increase in the bending degree can be stopped. Understandably, in the actual comparison operation, it can be set to compare the actual light leakage loss value with the first trigger threshold every time it increases by a certain decibel, in order to avoid the situation where the actual light leakage loss value exceeds the first trigger threshold due to excessive bending degree, which would affect the normal transmission operation 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 bending point. The actual light leakage loss value is compared in real time with the first trigger threshold. When the actual light leakage loss value reaches the first trigger threshold, a stop bending signal is triggered, stopping the current bending operation and performing a corresponding straightening operation on the optical fiber under test. In this embodiment, the fiber clamp needs to be clamped at one end of the optical fiber under test.
[0066] For example, an operator discovers a fiber optic cable requiring inspection or troubleshooting in one rack and needs to determine its exact location in another rack. Understandably, because racks contain a large number of fibers, and many are bundled for storage, identifying the fiber requires pairing tools for quick location. Therefore, a fiber clamping device generates a leakage signal at the identifiable end of the fiber, and a pairing device acquires the differential loss signals of each pairing fiber on the rack containing the fiber under test. This continues until the differential loss signal corresponding to the leakage signal generated by the bending and straightening operations is found, allowing the identification of the fiber under test.
[0067] In this embodiment, when the fiber clamping device begins bending the fiber under test, the bending angle of the fiber under test is continuously increased, causing the actual light leakage loss value of the fiber under test to continuously increase. It is understandable that for some fibers under test that have been in use for a long time, before the fiber clamping device bends them, the initial light leakage loss value may not be zero due to the wear and tear of the surface protective layer. When the fiber clamping device bends them, this initial light leakage loss value needs to be added to the existing value. If the initial light leakage loss value is greater than or equal to the first trigger threshold, it indicates that the surface wear of the fiber may pose a risk to normal transmission, and a warning can be issued, awaiting subsequent maintenance work. Since maintenance work is not the focus of this application, it will not be described in detail here.
[0068] Specifically, the fiber clamping device performs bending operations and corresponding straightening operations on the optical fiber under test, including:
[0069] The fiber clamping device performs several bending operations and corresponding straightening operations on the optical fiber under test. When the stop bending 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 under test.
[0070] Once the fiber under test has returned to its original state according to the corresponding straightening operation, the fiber clamping device initiates the next bending operation on the fiber under test.
[0071] In this embodiment, the leakage signal generated by a single bending operation of the optical fiber under test may be sporadic. In order to avoid the random error of leakage signal caused by human compression of the optical fiber or compression by heavy objects, as well as the random acquisition error of the fiber optic instrument, it is necessary to perform several bending operations and corresponding straightening operations on the optical fiber under test to achieve a regular signal flickering effect and reduce random errors.
[0072] Specifically, the bending operation includes: the fiber clamping device increases the clamping angle of the fiber under test at a certain speed, so as to increase the actual light leakage difference value generated by the fiber under test.
[0073] In this embodiment, the bending angle of the fiber under test by the fiber clamping device increases at a certain rate. Understandably, the angle increase per unit time will differ for different types of fibers, because the actual light leakage loss value generated at the same bending angle will vary for fibers of different thicknesses or types. However, for fibers of different thicknesses or types, the fiber clamping device has only one objective: to continuously change the degree of fiber bending, causing the actual light leakage loss value of the fiber to change continuously until the actual light leakage loss value reaches a first trigger threshold. Preferably, the speed at which the fiber clamping device 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 can increase at a uniform rate, thereby generating a uniform loss signal, which is beneficial for subsequent identification and matching.
[0074] Specifically, the straightening operation includes: the fiber clamping device maintaining a certain speed to reduce the clamping angle of the fiber under test, so as to reduce the actual light leakage difference value generated by the fiber under test.
[0075] In this embodiment, similarly, after the actual light leakage loss value reaches the first trigger threshold, the clamping angle of the fiber under test by the fiber clamping device needs to be reduced at a certain speed so that the actual light leakage loss value generated by the fiber under test can be continuously reduced. Preferably, the speed at which the fiber clamping device 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 can be reduced at a uniform speed, thereby generating a uniform loss signal, which is beneficial for subsequent identification and matching. Combining the characteristics of the bending and straightening operations of the fiber under test, the clamping angle of the fiber under test can be controlled so that the actual light leakage loss value generated by the fiber changes continuously, thereby making the loss signal obtained by the fiber clamping device also change continuously, so that when the loss signal is converted into a visual graphic, it is a regular waveform image. Because it is difficult to make the actual light leakage loss value of the fiber under test change regularly when manually touching and squeezing the fiber, this design can avoid manual interference to a certain extent.
[0076] Specifically, the fiber clamping device is equipped with a detection component for obtaining the actual light leakage difference value.
[0077] In this embodiment, the fiber clamping device is equipped with a detection component that can detect the actual light leakage difference value of the optical fiber at all times; preferably, the detection component is a detection probe set in the fiber clamping device near the optical fiber to be tested.
[0078] Specifically, the fiber clamping device is equipped with an electric drive device for performing the bending operation and the straightening operation on the fiber under test.
[0079] In this embodiment, the fiber clamping device is equipped with an electric drive device, which can perform regular bending and straightening operations on the fiber under test, so that the fiber under test can generate regular differential loss signals.
[0080] like Figure 2 As shown in the figure, this application embodiment also provides an optical fiber matching method based on fiber optic instrumentation, the method including the following steps:
[0081] S210, The fiber optic device presets a second trigger threshold and a matching strategy;
[0082] In this embodiment, a second trigger threshold needs to be preset in the fiber alignment instrument, and this second trigger threshold needs to be equal to the first trigger threshold of the fiber clamping instrument. This ensures that the fiber clamping instrument targets a suitable actual light leakage loss value to bend the optical fiber and generate a suitable light leakage signal, avoiding abnormal problems caused by insufficient or excessive bending. Simultaneously, it ensures that the light leakage signal generated by bending and straightening the fiber under test according to the first trigger threshold can trigger the second trigger threshold in the fiber alignment instrument for identification, allowing the instrument to locate the corresponding fiber under test. The preset matching strategy provides a matching basis for fiber alignment, working in conjunction with the second trigger threshold to match the fiber under test, thereby improving the efficiency and accuracy of matching.
[0083] S220. The fiber pairing instrument collects optical signals from each fiber to be paired, which contains the fiber to be tested, and extracts the corresponding differential loss signal based on the optical signal.
[0084] Understandably, a fiber optic pairing device is an advanced fiber identification and positioning device, based on the precise analysis and comparison of fiber optic signals. When it is necessary to locate or identify the fiber to be paired, the pairing device needs to be placed in the fiber optic bundle containing the fibers to be paired. By capturing the optical signal of each fiber to be paired, the processing system inside the pairing device quickly analyzes the captured optical signal to obtain the differential loss signal corresponding to each fiber to be paired. By comparing the characteristic parameters of the differential loss signal, such as wavelength, intensity, and phase, it can be accurately determined which fiber to be paired is the fiber to be tested. Understandably, the pairing device and the fiber clamping device work together to form an indispensable and important part of the fiber pairing process in an optical fiber communication system.
[0085] In this embodiment, the fiber optic clamping device includes multiple detection holes, which are used to connect the receiving ends of multiple optical fibers to be paired, thereby acquiring the corresponding optical signals. It can be understood that each detection hole in the fiber optic clamping device detects the optical signal of each optical fiber to be paired, and the differential 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, thereby determining whether the optical fiber to be paired is the fiber to be tested. Because for optical fibers that have not undergone bending and straightening operations, only a slight transmission loss can be obtained at the receiving end of the optical fiber to be paired, without a uniform and regular differential loss signal based on the fiber clamping device, it is necessary to extract the differential 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 difference loss signal is a leakage light signal based on the second trigger threshold and the matching strategy. If so, the fiber to be paired that generates the difference loss signal is determined to be the fiber to be tested. The leakage light signal is generated when the fiber to be tested is bent and straightened a number of times using the fiber clamping method and the fiber clamping instrument as described above. The first trigger threshold is equal to the second trigger threshold.
[0087] In this embodiment, the fiber optic instrument sequentially acquires the corresponding optical signal for each fiber in the fiber optic set containing the fiber to be paired, and extracts the corresponding differential loss signal based on the optical signal. If the differential loss signal of a certain fiber to be paired corresponds one-to-one with the leakage light signal generated by the fiber clamping instrument, then the fiber to be paired is the fiber to be tested, thereby obtaining the specific location of the fiber to be tested on another rack or another row of points.
[0088] Specifically, such as Figure 3 As shown, the fiber pairing instrument determines whether the difference loss signal is a leakage signal based on the second trigger threshold and the matching strategy. If so, it determines that the fiber to be paired that generated the difference loss signal is the fiber to be tested, including the following steps:
[0089] S231. The waveform of the differential loss signal acquired by the fiber optic cable;
[0090] In this embodiment, the acquired loss signal can be displayed as a visualized waveform image;
[0091] S232. If, in the waveform of the difference loss signal, there is a preset number of uniformly changing waveforms and the peak value of each uniformly changing waveform reaches the second trigger threshold, then the fiber pairing instrument determines that the difference loss signal triggers the matching strategy and determines that the fiber to be paired that generates the difference loss signal is the fiber to be tested.
[0092] In this embodiment, the fiber under test is clamped by a fiber clamping device based on several bending and straightening operations. The resulting differential loss signal normally consists of several uniform symmetrical waveforms, and the peak value of each uniformly changing waveform is equal to the second trigger threshold. Considering the random error in the fiber clamping device's reception, a matching strategy is set if a preset number of uniformly changing waveforms exist and the peak value of each uniformly changing waveform reaches the second trigger threshold. When the differential loss signal can trigger this matching strategy, the fiber to be paired that generates the differential loss signal is determined to be the fiber under test.
[0093] In this embodiment, the fiber to be paired is determined to be the fiber under test based on the corresponding differential loss signal. This can avoid human error and random reception error in fiber pairing, improve the accuracy and identification efficiency of fiber pairing, and ensure the smooth progress of fiber pairing.
[0094] Preferably, the fiber clamping device is placed at several rack positions of the fiber under test and generates several leakage signals to it. At the same time, a differential loss signal is received at the fiber to be paired. The routing status of the fiber under test is obtained through the differential loss signal received by the fiber clamping device and the corresponding generation position.
[0095] Understandably, optical fibers can be laid out across multiple floors or different buildings, and there may be spatial limitations in obtaining their specific routing. The method of this application can also be applied to the field of obtaining the accurate routing of optical fibers. After obtaining the specific location of the optical fiber under test in a single area where the optical fiber is stored, a fiber clamping device is placed at multiple specific locations on the optical fiber and clamped to it, generating differential loss signals at several different locations. The fiber clamping device can obtain the specific locations of the optical fiber under test by determining whether it can receive the differential loss signal at that location, thereby obtaining the global distribution of the optical fiber under test.
[0096] Understandably, the fiber optic cable can have a built-in communication component to obtain the specific location of each fiber clipper and add location information to the differential loss signal received by the fiber optic cable, thereby quickly obtaining the routing direction of the fiber under test; preferably, the communication component can be a Bluetooth component or other wireless communication module capable of transmitting over longer distances.
[0097] like Figure 4 As shown in the illustration, this application also provides a method for fiber-to-fiber pairing, which may include the following steps:
[0098] S310. A first trigger threshold is preset in the fiber clamping device, and a second trigger threshold and matching strategy are preset in the fiber pairing device; wherein the first trigger threshold is equal to the second trigger threshold;
[0099] S320. Using the fiber clamping device, the fiber under test is bent several times and a straightening operation is performed after each bending operation based on the first trigger threshold, so that the fiber under test generates a light leakage signal.
[0100] S330. The optical signal of each optical fiber to be paired containing the optical fiber under test is collected using the fiber pairing instrument, and the corresponding difference loss signal is extracted according to the optical signal. The difference loss signal corresponding to the leakage signal is determined according to the difference loss signal, the matching strategy and the second trigger threshold. The corresponding optical fiber to be paired is determined as the optical fiber under test according to the corresponding difference loss signal.
[0101] This embodiment proposes a fiber-to-fiber method that uses a fiber clamping device to achieve the effect of electrically bending the fiber under test. This allows for the generation of appropriate actual light leakage loss values under the clamping of different types of fibers with different usage times, ensuring normal reception of the fiber-to-fiber device. Furthermore, the fiber clamping device is simple to operate; after clamping it onto the fiber under test, the operator does not need to perform further operations. The clamping angle of the fiber under test is executed by the internal program of the fiber clamping device, freeing the operator's hands and improving the efficiency of fiber clamping and pairing.
[0102] like Figure 5 As shown in the illustration, this application also provides a fiber-to-fiber system, the system comprising a fiber clamping device and a fiber-to-fiber pairing device, wherein:
[0103] The fiber clamping device is used to preset a first trigger threshold, and to perform several bending operations on the fiber under test and to perform a corresponding straightening operation after each bending operation based on the first trigger threshold, so that the fiber under test generates a light leakage signal.
[0104] The fiber pairing instrument is used to preset a second trigger threshold and a matching strategy, and to connect each pairing fiber containing the fiber under test, collect the optical signal of the pairing fiber, extract the corresponding differential loss signal based on the optical signal, determine the differential loss signal corresponding to the leakage signal based on the differential loss signal, the matching strategy and the second trigger threshold, and determine the corresponding pairing fiber as the fiber under test based on the corresponding differential loss signal.
[0105] The first trigger threshold is equal to the second trigger threshold.
