Technical Field

[0003] The present application relates to the field of optical fiber communication technology, and in particular to a fiber-finding device, a processing device, a fiber-finding system, and a fiber-finding method. Background Art

[0004] With the rapid development of the communications industry, the number of optical fibers in optical communication networks is increasing. However, since optical fiber is a passive transmission medium, it is difficult for communication equipment and network elements to effectively monitor and manage the passive resources of the optical fiber network. This makes optical fiber management more difficult, leading to issues such as invisible routing of massive optical fibers, unknown resources, and difficulty locating faults.

[0005] In related technologies, optical fibers in optical communication networks are mainly managed manually, which makes it difficult to quickly and accurately match the port information at both ends of the optical fiber.

[0006] Summary of the Invention

[0007] Embodiments of the present application provide a fiber-finding device, a processing device, a fiber-finding system, and a fiber-finding method for quickly and accurately matching port information at both ends of an optical fiber.

[0008] In the first aspect, an embodiment of the present application provides a fiber-finding system. The fiber-finding system provided by the embodiment of the present application may include: a fiber-finding device and a processing device. Among them, the fiber-finding system is used to match the port information of the first end of the optical fiber with the port information of the second end. In specific implementation, according to the flow direction of light in the optical fiber, the upstream of the optical fiber may be the first end, and the downstream of the optical fiber may be the second end. In the embodiment of the present application, the upstream of the optical fiber is the first end, and the downstream of the optical fiber is the second end as an example for explanation. In some cases, the upstream of the optical fiber may also be the second end, and the downstream of the optical fiber may also be the first end, which is not limited here. The port information of the first end may be the information of the first end itself, or the information of the device connected to the first end. The port information of the second end may be the information of the second end itself, or the information of the device connected to the second end.

[0009] The above-mentioned fiber-finding device may include: a signal detector. The signal detector may include: at least one detection unit, a first processing module and a communication module. Each detection unit can be used to clamp the signal detection area of ​​an optical fiber, and to detect the optical signal intensity of the signal detection area of ​​the clamped optical fiber. Different detection units are used to clamp the signal detection areas of different optical fibers, and to detect the optical signal intensity of the signal detection areas of different clamped optical fibers. Among them, the signal detection area of ​​any optical fiber is close to the second end of the optical fiber. The first processing module is used to compare the change amplitude of the optical signal intensity detected by each detection unit with the set threshold value to determine the target detection unit. The target detection unit is the detection unit whose change amplitude of the optical signal intensity of the signal detection area exceeds the set threshold value. The communication module is used to send the identification information of the target detection unit to the processing device.

[0010] The above-mentioned processing device is used to: receive the identification information of the target detection unit sent by the signal detector; determine the port information of the second end of the optical fiber to be found based on the received identification information of the target detection unit and the preset correspondence relationship, the optical fiber to be found is one of the multiple optical fibers, and the correspondence relationship is a one-to-one correspondence between the identification information of multiple detection units and the port information of the second ends of the multiple optical fibers; match the port information of the second end of the optical fiber to be found with the pre-acquired port information of the first end of the optical fiber to be found; the optical fiber to be found is an optical fiber with a fiber-seeking signal applied to the first end, and the fiber-seeking signal is used to cause the intensity of the optical signal transmitted in the optical fiber to be found to change, and the amplitude of the change exceeds the set threshold.

[0011] In the embodiment of the present application, the number of signal detectors in the fiber-finding device can be one or more, and the number of detection parts in the signal detector can be one or more. In specific implementation, the number of signal detectors and detection parts can be set according to actual needs, and is not limited here.

[0012] The following introduces the process of fiber finding using the fiber finding system in the embodiment of the present application.

[0013] When searching multiple optical fibers, a signal detector can be installed at the second end of each optical fiber. Specifically, a detection unit can be clamped in the signal detection area of ​​each optical fiber. Optionally, the number of signal detectors can be one or more, and each signal detector can be provided with one or more detection units. The identification information of each detection unit is bound to the port information of the second end of each clamped optical fiber, and the correspondence between the identification information of the detection unit and the port information of the second end of the optical fiber is pre-stored in the processing device.

[0014] Then, an optical fiber is selected from multiple optical fibers as the optical fiber to be found, and the port information of the first end of the optical fiber to be found is stored in the processing device. A fiber-finding signal is applied to the signal input area of ​​the optical fiber to be found, wherein the signal input area is the area close to the first end of the optical fiber to be found. Since the fiber-finding signal can cause the intensity of the optical signal transmitted in the optical fiber to change, the optical signal intensity of the clamped optical fiber in the signal detection area can be detected by the detection unit. When the optical signal intensity detected by the detection unit is greater than the set threshold, it means that the change amplitude of the optical signal intensity of the optical fiber clamped by the detection unit is large, that is, the optical fiber clamped by the detection unit is the optical fiber to be found. The optical signal intensity detected by each detection unit can be monitored by a signal detector, and when the change amplitude of the optical signal intensity detected by the detection unit exceeds the set threshold, the identification information of the detection unit is sent to the processing device.

[0015] Afterwards, the processing device can determine the port information of the second end of the optical fiber to be found based on the identification information of the received detection unit and the preset correspondence (a one-to-one correspondence between the identification information of multiple detection units and the port information of the second ends of multiple optical fibers), and match the port information of the second end of the optical fiber to be found with the pre-acquired port information of the first end of the optical fiber to be found.

[0016] Next, another optical fiber is selected from the multiple optical fibers as the optical fiber to be found, and the port information of the first end and the port information of the second end of the optical fiber to be found are matched in the above manner, thereby matching the port information of the two ends of the multiple optical fibers one by one.

[0017] Based on the above analysis, in the fiber-finding system provided in the embodiment of the present application, a signal detector is provided in the fiber-finding device, and the signal detector includes at least one detection part. During the fiber-finding process, the detection part in the signal detector can be clamped in the signal detection area of ​​the optical fiber, and a fiber-finding signal can be added to the signal input area of ​​the optical fiber to be found. When the amplitude of the change in the optical signal intensity of the detection part of the signal detector exceeds a set threshold, the identification information of the detection part can be sent to the processing device, and the data can be processed by the processing device to match the port information of the first end and the port information of the second end of the optical fiber to be found. Thus, the port information at both ends of the optical fiber can be matched quickly and accurately, and there is no need to pull out the optical fiber, which will not affect the connection relationship between the optical fiber and other devices, and there is no need to interrupt the existing network services.

[0018] In addition, the fiber-finding signal can cause the intensity of the optical signal transmitted in the optical fiber to change. In this way, by detecting the optical signal intensity in the signal detection area of ​​the optical fiber through the detection unit and judging whether the change amplitude of the optical signal intensity exceeds the set threshold, the port information of the second end of the optical fiber to be found can be determined, and the port information of the first end of the optical fiber can be matched with the port information of the second end. In the fiber-finding process, the intensity change of the optical signal transmitted by the optical fiber is used for fiber-finding. The transmission distance of the business optical signal transmitted in the optical fiber is relatively long, generally 40km to 80km. Therefore, the fiber-finding distance is basically consistent with the transmission distance of the business optical signal. The fiber-finding distance in the embodiment of the present application is relatively long, generally up to 20km, or even up to 40km to 80km, which can realize cross-station detection of optical fibers.

[0019] In some embodiments of the present application, when service light is transmitted in an optical fiber, fiber tracing can be performed using changes in the intensity of the optical signal transmitted by the optical fiber. Specifically, the optical fiber to be traced can be controlled to generate a macrobend of a set degree in the signal input region. For example, the radius of the macrobend can be approximately 5.9 mm, causing the optical fiber to be traced to generate leakage light in the signal input region, thereby causing a certain degree of intensity attenuation of the optical signal transmitted in the optical fiber to be traced (i.e., causing the intensity of the optical signal transmitted in the optical fiber to be traced to change), thereby applying a fiber tracing signal to the signal input region. The detection unit is clamped in the signal detection region of the optical fiber, and can cause the optical fiber to generate a macrobend of a set degree in the signal detection region. For example, the radius of the macrobend can be approximately 5.9 mm, causing the optical fiber to generate leakage light in the signal detection region. If the signal input region of the optical fiber is subjected to a macrobend of a set degree, the intensity of the optical signal transmitted in the optical fiber will decrease, and the leakage light intensity of the optical fiber in the signal detection region will also decrease. Therefore, by detecting the leakage light intensity of the optical fiber in the signal detection region (i.e., detecting the optical signal intensity of the optical fiber in the signal detection region) and determining whether the change in the leakage light intensity exceeds a set threshold, it is possible to determine whether the optical fiber is the fiber to be traced.

[0020] During the fiber-finding process, the fiber-finding signal can cause the optical signal transmitted in the optical fiber to change by about 1 dB, that is, the fiber-finding process has little impact on the optical signal in the optical fiber to be found, and the fiber-finding process will not affect the existing network services.

[0021] In specific implementation, a variety of methods can be used to apply the fiber-finding signal to the signal input area of ​​the optical fiber to be found. Several methods are described below with examples.

[0022] Method 1:

[0023] The fiber-finding device may further include a signal generator, the signal generator being clamped to the signal input region of any optical fiber and configured to apply a fiber-finding signal to the signal input region of the clamped optical fiber, the fiber-finding signal being configured to cause an intensity change in the optical signal transmitted in the optical fiber, wherein the signal input region of any optical fiber is proximate to the first end of the optical fiber. In embodiments of the present application, the fiber-finding device may include one or more signal generators.

[0024] During the fiber-searching process, the signal generator can be clamped in the signal input area of ​​the optical fiber to be searched, so that the optical fiber to be searched produces a macrobend of a set degree in the signal input area, so that the optical fiber to be searched produces leakage light in the signal input area, and then the intensity of the optical signal transmitted in the optical fiber to be searched is attenuated, thereby realizing the application of the fiber-searching signal to the signal input area.

[0025] Method 2:

[0026] The signal input area of ​​the optical fiber to be found can be manually bent to make the optical fiber to be found produce a macrobend of a set degree in the signal input area, so that the optical fiber to be found produces leakage light in the signal input area, and then the intensity of the optical signal transmitted in the optical fiber to be found is attenuated, thereby realizing the application of the fiber-seeking signal to the signal input area.

[0027] In other embodiments of the present application, when no service light is transmitted in the optical fiber to be found, a fiber-searching signal can be injected into the first end of the optical fiber to be found. For example, simulated service light or an optical signal of other wavelengths (such as red light) can be injected into the first end of the optical fiber to be found, so as to increase the intensity of the optical signal transmitted in the optical fiber to be found. The detection unit is clamped in the signal detection area of ​​the optical fiber, and can cause the optical fiber to generate a macrobend of a set degree in the signal detection area. For example, the radius of the macrobend can be around 5.9 mm, so that the optical fiber generates leakage light in the signal detection area. If a fiber-searching signal is injected into the first end of the optical fiber, the intensity of the optical signal transmitted in the optical fiber will increase, and then the leakage light intensity of the optical fiber in the signal detection area will also increase accordingly. Therefore, by detecting the leakage light intensity of the optical fiber in the signal detection area (that is, detecting the optical signal intensity of the signal detection area of ​​the optical fiber), and judging whether the change in the leakage light intensity exceeds the set threshold, it can be judged whether the optical fiber is the optical fiber to be found.

[0028] During specific implementation, in order to prevent the optical signal intensity change caused by normal business interaction or manual combing of optical fibers from causing misoperation of the fiber-finding device, the threshold value can be set to a value greater than the optical signal intensity change value caused by normal business interaction or manual combing of optical fibers. For example, the threshold value can be set to be greater than 0.2dB, for example, it can be set to a value such as 0.5dB, 0.6dB or 1dB. Of course, the value of the threshold value cannot be too large to prevent the inability to determine the optical fiber to be found due to the setting of the threshold value being too large. The specific value of the threshold value can be set according to the actual application scenario, and is not limited here.

[0029] Furthermore, in some embodiments of the present application, the fiber-finding system may further include a fiber management platform. The fiber management platform is configured to receive and store pairing information sent by the processing device; the pairing information includes port information for the first end and port information for the second end of the optical fiber to be found. In a specific implementation, after matching the port information for the second end of the optical fiber to be found with the port information for the first end, the processing device may send the matched pairing information to the fiber management platform. The fiber management platform may then store the pairing information for multiple optical fibers, thereby enabling digital management of optical fibers.

[0030] In a possible implementation, the signal detector may communicate directly with the processing device, that is, the signal detector may directly send identification information of the target detection unit to the processing device.

[0031] In another possible implementation, the signal detector can communicate indirectly with the processing device. Specifically, the signal detector can be used to send identification information of the target detection unit whose optical signal intensity change amplitude exceeds a set threshold to the optical fiber management platform. The optical fiber management platform can also be used to receive the identification information of the target detection unit, and send the received identification information of the target detection unit to the processing device. In other words, the optical fiber management platform can also play the role of information transmission. The signal detector can send the identification information of the target detection unit to the processing device through the optical fiber management platform, so that the processing device determines the port information of the second end of the optical fiber to be found based on the received identification information of the target detector and the preset corresponding relationship, matches the port information of the second end of the optical fiber to be found with the pre-acquired port information of the first end of the optical fiber to be found, and sends the matched pairing information to the optical fiber management platform.

[0032] In practical applications, the processing device can be a mobile terminal with processing capabilities, such as a mobile phone or tablet, or a device with processing capabilities, such as a chip or circuit board, or a device with processing capabilities, such as a computer or server. The fiber management platform can be a device with strong processing capabilities, such as a computer or server.

[0033] The specific structure of the fiber-finding device in the embodiment of the present application is described in detail below.

[0034] The signal generator may include: a first clamping member, which is used to clamp the signal input area of ​​any optical fiber, causing the clamped optical fiber to produce a set degree of macrobend, so that the optical fiber produces leakage light in the signal input area, thereby applying a fiber-seeking signal to the signal input area.

[0035] During the fiber-searching process, the first clamping member of the signal generator can be clamped in the signal input area of ​​the optical fiber to be searched, so that the optical fiber to be searched produces a macrobend of a set degree in the signal input area. For example, the radius of the macrobend can be around 5.9 mm, so that the optical fiber to be searched produces leakage light in the signal input area, and then the intensity of the optical signal transmitted in the optical fiber to be searched is attenuated, thereby realizing the application of a fiber-searching signal to the signal input area of ​​the optical fiber to be searched.

[0036] In one possible implementation, the first clamping member may include a slot and a sliding cover. The signal input area of ​​the optical fiber can be placed within the slot, and the sliding cover can then be controlled to cooperate with the slot to produce a macrobend of a predetermined degree in the optical fiber. In a specific implementation, a slide rail can be provided in the signal generator, along which the sliding cover can slide. The sliding cover can be pushed to produce a macrobend in cooperation with the slot. Alternatively, a button can be provided in the signal generator to control the sliding of the sliding cover, which can be used to control the sliding cover to cooperate with the slot to produce a macrobend in the optical fiber. Alternatively, a bolt can be provided in the signal generator to drive the sliding cover, which can be driven by tightening the bolt to drive the sliding cover to produce a macrobend in cooperation with the slot. Of course, other methods for controlling the sliding cover can also be used, and these examples are not given here. In one possible implementation, the sliding cover can be configured in an arc shape, and pressing the sliding cover can cause the sliding cover to move in a predetermined direction. In specific implementation, the optical fiber can be placed in the card slot, and then the slide cover is pressed to move one end of the slide cover to the position of the card slot. The slide cover cooperates with the card slot to make the optical fiber generate a set degree of macrobend.

[0037] In another possible implementation, the first clamping member may also be a fixture. During the fiber search process, the fixture can be opened to place the optical fiber to be searched within the fixture. The fixture is then closed to cause a macrobend of a predetermined degree to be generated in the optical fiber. Of course, the first clamping member in the embodiment of the present application may also be implemented in other ways, which will not be exemplified here.

[0038] Furthermore, the signal generator may also include: a signal source for providing a fiber-finding signal, the signal source being used to inject a fiber-finding signal into the first end of any optical fiber when no service light is transmitted in the optical fiber. Specifically, the signal source can generate simulated service light or an optical signal of other wavelengths (e.g., red light) as a fiber-finding signal. By injecting a fiber-finding signal into the first end of the optical fiber to be found, the intensity of the optical signal transmitted in the optical fiber to be found can be increased. Therefore, by detecting the optical signal intensity of the optical fiber in the signal detection area through a signal detector and determining whether the variation in the optical signal intensity exceeds a set threshold, it is possible to determine whether the optical fiber is the optical fiber to be found.

[0039] In one possible implementation, a signal detector may include: at least one detection unit, a first processing module, and a communication module. The first processing module is configured to compare the amplitude of the change in optical signal intensity detected by each detection unit with a set threshold value to identify a target detection unit, which is the detection unit whose amplitude of the change in optical signal intensity in the signal detection area exceeds the set threshold value. The communication module is configured to transmit identification information of the target detection unit to a processing device. In a specific implementation, the first processing module may be electrically connected to each detection unit in the signal detector.

[0040] Optionally, the communication module may be a device with communication function such as a Bluetooth module or a SIM card.

[0041] In some embodiments of the present application, the signal detector may include multiple detection unit groups, each of which may include multiple detection units. In specific implementations, the number of detection unit groups and the number of detection units in each detection unit group may be set according to actual needs and are not limited here.

[0042] In addition, the signal detector may also include: a plurality of second processing modules, each detection part group is electrically connected to a second processing module, the second processing module is used to compare the change amplitude of the optical signal intensity detected by each detection part in the connected detection part group with the set threshold value, determine the target detection part, and send the identification information of the target detection part to the first processing module; wherein the target detection part is the detection part whose optical signal intensity change amplitude exceeds the set threshold value in the signal detection area. In the embodiment of the present application, by dividing the multiple detection parts in the signal detector into multiple detection part groups and providing second processing modules corresponding to the multiple detection part groups one by one, the second processing module processes the detection data generated by each detection part in the corresponding detection part group, and sends the processing result (i.e., the identification information of the detection part whose optical signal intensity change amplitude exceeds the set threshold value) to the first processing module, the data processing amount of the first processing module can be reduced and the data processing speed can be improved.

[0043] In one possible implementation, the detection unit may include a second clamping member and a photosensor. The second clamping member is configured to clamp the signal detection region of any optical fiber and induce a macrobend of a predetermined degree in the optical fiber, thereby causing leakage light from the optical fiber in the signal detection region. The photosensor, located within the second clamping member, is configured to detect the intensity of the light leakage from the optical fiber in the signal detection region.

[0044] During the fiber-searching process, the second clamping member of the detection part can be clamped in the signal detection area of ​​the optical fiber, so that the optical fiber produces a macrobend of a set degree in the signal detection area. For example, the radius of the macrobend can be around 5.9 mm, so that the optical fiber produces leakage light in the signal detection area. The photosensitive sensor located inside the second clamping member can detect the intensity of the leakage light, thereby realizing the detection of the optical signal intensity in the signal detection area.

[0045] In one possible implementation, the second clamping member may include a slot and a sliding cover, wherein the slot and the sliding cover cooperate to clamp the signal detection area of ​​the optical fiber and induce a macrobend of a predetermined degree in the optical fiber. In a specific implementation, a slide rail may be provided in the detection unit, along which the sliding cover can slide. The sliding cover can be pushed to slide, thereby cooperating with the slot to induce a macrobend in the optical fiber. Alternatively, a button for controlling the sliding cover can be provided in the detection unit, thereby controlling the sliding cover to cooperate with the slot to induce a macrobend in the optical fiber. Alternatively, a bolt can be provided in the detection unit to drive the sliding cover to move, thereby cooperating with the slot to induce a macrobend in the optical fiber by tightening the bolt. Of course, other methods for controlling the sliding cover can also be used, and these examples are not given here.

[0046] In some embodiments of the present application, multiple second clamping members can share a common sliding cover. In practice, multiple optical fibers can be placed in separate slots. The shared sliding cover can then be controlled to slide, cooperating with each slot to induce a macrobend of a predetermined degree on the multiple optical fibers. This allows simultaneous macrobending of multiple optical fibers, simplifying the operation process.

[0047] In another possible implementation, the second clamping member can also be a fixture, with the photosensor disposed within the fixture. During fiber tracing, the fixture can be opened to place the fiber to be traced within it, and then closed to induce a macrobend of a predetermined degree in the fiber. Of course, the second clamping member in the embodiment of the present application can also be implemented in other ways, which will not be exemplified here.

[0048] In the second aspect, the embodiment of the present application also provides a fiber-finding method applied to the fiber-finding system in the first aspect. The fiber-finding method applied to the fiber-finding system provided by the embodiment of the present application may include: the fiber-finding device sends identification information of the target detection unit whose optical signal intensity variation exceeds a set threshold to the processing device; the processing device determines the port information of the second end of the optical fiber to be found based on the received identification information of the target detection unit and the preset correspondence relationship, the optical fiber to be found is one of the multiple optical fibers, and the correspondence relationship is a one-to-one correspondence between the identification information of the multiple detection units and the port information of the second ends of the multiple optical fibers; the processing device matches the port information of the second end of the optical fiber to be found with the pre-acquired port information of the first end of the optical fiber to be found; the optical fiber to be found is an optical fiber to which a fiber-finding signal is applied at the first end, and the fiber-finding signal is used to cause the optical signal transmitted in the optical fiber to be found to have an intensity change, and the variation amplitude exceeds the set threshold.

[0049] The fiber-finding method provided in the embodiments of this application can quickly and accurately match the port information at both ends of an optical fiber. Furthermore, by utilizing the intensity changes of optical signals transmitted by optical fibers for fiber-finding, the fiber-finding distance can be long, typically up to 20 km, or even 40 to 80 km, enabling cross-site fiber detection.

[0050] Furthermore, the fiber-finding method in the embodiment of the present application may also include: the processing device sends pairing information to the optical fiber management platform; wherein the pairing information includes the port information of the first end and the port information of the second end of the optical fiber to be found; the optical fiber management platform receives and stores the pairing information sent by the processing device.

[0051] In an embodiment of the present application, the processing device can send the pairing information of the matched optical fibers to the optical fiber management platform, and the optical fiber management platform can store the pairing information of multiple optical fibers, thereby realizing digital management of the optical fibers.

[0052] In a possible implementation, the fiber-finding device may communicate directly with the processing device, that is, the fiber-finding device may directly send identification information of the target detection unit to the processing device.

[0053] In another possible implementation, the fiber-finding device can communicate indirectly with the processing device. The fiber-finding device sending identification information of a target detector unit indicating that the magnitude of the change in optical signal intensity exceeds a set threshold to the processing device can specifically include: the fiber-finding device sending the identification information of the target detector unit to the optical fiber management platform; and the optical fiber management platform receiving the identification information of the target detector unit and sending the received identification information of the target detector unit to the processing device.

[0054] That is to say, the optical fiber management platform can also play the role of information transmission. The fiber-finding device can send the identification information of the target detector to the processing device through the optical fiber management platform, so that the processing device can determine the port information of the second end of the optical fiber to be found based on the received identification information of the target detection part and the preset correspondence, match the port information of the second end of the optical fiber to be found with the pre-acquired port information of the first end of the optical fiber to be found, and send the matched pairing information to the optical fiber management platform.

[0055] In a third aspect, an embodiment of the present application further provides a processing device. The processing device provided by the embodiment of the present application may include: a transceiver unit for receiving identification information of a target detection unit sent by a signal detector; a processing unit for: determining the port information of the second end of the optical fiber to be found based on the received identification information of the target detection unit and a preset correspondence relationship, wherein the optical fiber to be found is one of the multiple optical fibers, and the correspondence relationship is a one-to-one correspondence between the identification information of the multiple detection units and the port information of the second ends of the multiple optical fibers; matching the port information of the second end of the optical fiber to be found with the pre-acquired port information of the first end of the optical fiber to be found; the optical fiber to be found is an optical fiber to which a fiber-seeking signal is applied at the first end, and the fiber-seeking signal is used to cause the optical signal transmitted in the optical fiber to be found to produce an intensity change, and the change amplitude exceeds a set threshold.

After the processing unit determines the port information of the second end of the optical fiber to be found, the processing unit may read the port information of the first end of the optical fiber to be found stored in the storage unit, thereby facilitating matching of the port information of the two ends of the optical fiber to be found.

[0058] Furthermore, in an embodiment of the present application, the transceiver unit can also be used to send pairing information to a fiber management platform; wherein the pairing information includes the port information of the first end and the port information of the second end of the optical fiber to be found.

DETAILED DESCRIPTION

[0093] In the related art, in order to match the port information at both ends of the optical fiber, it is necessary to manually unplug one end of the optical fiber, inject red light into the end face of the optical fiber as a detection signal, and set a red light receiver on the end face of the other end of the optical fiber. When the red light receiver senses the detection signal, the port information at both ends of the optical fiber can be matched. The fiber-finding method in the related art requires interrupting the existing network service, and because the transmission distance of the red light itself is short, the fiber-finding distance of the optical fiber is short (generally within 2km). However, the distance between base stations is generally greater than 5km. Therefore, the fiber-finding method in the related art is difficult to achieve cross-station detection.

[0094] Based on this, the embodiments of the present application provide a fiber-finding device, a processing device, a fiber-finding system, and a fiber-finding method. The solution provided by the embodiments of the present application can be applied to optical communication networks. By using the solution provided by the embodiments of the present application to find optical fibers, the port information at both ends of the optical fibers can be quickly and accurately matched without interrupting existing network services. In addition, the fiber-finding distance of the optical fibers is relatively long, generally up to 20 km, or even up to 40 km to 80 km, which can realize cross-site detection of optical fibers.

[0095] In order to make the purpose, technical solutions and advantages of this application clearer, this application will be further described in detail below with reference to the accompanying drawings.

[0096] It should be noted that the same reference numerals in the drawings of this application represent the same or similar structures, and thus their repeated description will be omitted. The words expressing positions and directions described in this application are all explained using the drawings as examples, but they can be modified as needed, and such modifications are included in the scope of protection of this application. The drawings of this application are only for illustrating relative positional relationships and do not represent true proportions.

[0097] FIG1 is a schematic diagram of the structure of the fiber-finding system provided in an embodiment of the present application, and FIG2 is a schematic diagram of the fiber-finding process of the fiber-finding system in an embodiment of the present application. In combination with FIG1 and FIG2, in some embodiments of the present application, the fiber-finding system may include: a fiber-finding device 11 and a processing device 12. Among them, the fiber-finding system can be used to match the port information of the first end A of the optical fiber 200 with the port information of the second end Z. In a specific implementation, according to the flow direction of light in the optical fiber 200, the upstream of the optical fiber 200 can be the first end A, and the downstream of the optical fiber 200 can be the second end Z. In the embodiment of the present application, the upstream of the optical fiber 200 is the first end A, and the downstream of the optical fiber 200 is the second end Z as an example for explanation. In some cases, the upstream of the optical fiber 200 can also be the second end Z, and the downstream of the optical fiber 200 can also be the first end A, which is not limited here. The port information of the first end A can be the information of the first end A itself, or the information of the device connected to the first end A. The port information of the second end Z can be the information of the second end Z itself, or the information of the device connected to the second end Z.

[0098] The fiber-finding device 11 may include a signal detector 101. The signal detector 101 may include at least one detector unit 1011, a first processing module 1012, and a communication module 1013. Each detector unit 1011 may be clamped to the signal detection area 201 of an optical fiber 200 and configured to detect the optical signal intensity of the clamped signal detection area 201 of the clamped optical fiber 200. Different detector units 1011 may be clamped to the signal detection areas 201 of different optical fibers 200 and configured to detect the optical signal intensity of the clamped signal detection areas 201 of the clamped optical fibers 200. The signal detection area 201 of any optical fiber 200 is located near the second end Z of the optical fiber 200. The first processing module 1012 is configured to compare the variation in the optical signal intensity detected by each detector unit 1011 with a set threshold value to identify a target detector unit. The target detector unit is the detector unit 1011 whose variation in the optical signal intensity of its signal detection area exceeds the set threshold value. The communication module 1013 is configured to transmit identification information of the target detector unit to the processing device 12.

[0099] The processing device 12 is used to: receive the identification information of the target detection unit sent by the signal detector 101; determine the port information of the second end Z of the optical fiber to be found based on the received identification information of the target detection unit and a preset correspondence, the optical fiber to be found is one of the multiple optical fibers 200, and the correspondence is a one-to-one correspondence between the identification information of multiple detection units 1011 and the port information of the second ends Z of the multiple optical fibers 200; match the port information of the second end Z of the optical fiber to be found with the pre-acquired port information of the first end A of the optical fiber to be found; the optical fiber to be found is the optical fiber 200 whose first end A is applied with a fiber-seeking signal, and the fiber-seeking signal is used to cause the intensity of the optical signal transmitted in the optical fiber to be found to change, and the amplitude of the change exceeds a set threshold.

[0100] In the embodiment of the present application, the number of signal detectors 101 in the fiber-finding device 11 can be one or more, and the number of detection units 1011 in the signal detector 101 can be one or more. In specific implementation, the number of signal detectors 101 and detection units 1011 can be set according to actual needs, and is not limited here.

[0101] Continuing with reference to FIG2 , the process of searching for fibers using the fiber-searching system in the embodiment of the present application is introduced. When searching for fibers of multiple optical fibers 200 (six optical fibers 200 are used as an example in FIG2 ), a signal detector 101 can be installed at the second end Z of each optical fiber 200. Specifically, a detection unit 1011 can be clamped in the signal detection area 201 of each optical fiber 200. Optionally, the number of signal detectors 101 can be one or more, and each signal detector 101 can be provided with one or more detection units 1011. The identification information of each detection unit 1011 is bound to the port information of the second end Z of each clamped optical fiber 200, and the correspondence between the identification information of the detection unit 1011 and the port information of the second end Z of the optical fiber 200 is pre-stored in the processing device 12.

[0102] Then, one optical fiber 200 is selected from the multiple optical fibers 200 as the optical fiber to be found, and the port information of the first end A of the optical fiber to be found is stored in the processing device 12. A fiber-finding signal is applied to the signal input area 202 of the optical fiber to be found, where the signal input area 202 is the area near the first end A of the optical fiber to be found. Because the fiber-finding signal can cause the intensity of the optical signal transmitted in the optical fiber 200 to change, the optical signal intensity of the clamped optical fiber 200 in the signal detection area 201 can be detected by the detection unit 1011. When the optical signal intensity detected by the detection unit 1011 is greater than a set threshold, it indicates that the optical signal intensity of the optical fiber 200 clamped by the detection unit 1011 has a large change, that is, the optical fiber 200 clamped by the detection unit 1011 is the optical fiber to be found. The optical signal intensity detected by each detection unit 1011 can be monitored by the signal detector 101, and when the change in the optical signal intensity detected by the detection unit 1011 exceeds the set threshold, the identification information of the detection unit 1011 is sent to the processing device 12.

[0103] Afterwards, the processing device 12 can determine the port information of the second end Z of the optical fiber to be found based on the identification information received from the detection unit 1011 and the preset correspondence (a one-to-one correspondence between the identification information of multiple detection units 1011 and the port information of the second ends Z of multiple optical fibers 200), and match the port information of the second end Z of the optical fiber to be found with the pre-acquired port information of the first end A of the optical fiber to be found.

[0104] Next, another optical fiber 200 is selected from the multiple optical fibers 200 as the optical fiber to be found, and the port information of the first end A of the optical fiber to be found is matched with the port information of the second end Z. Thus, the port information of both ends of the multiple optical fibers 200 are matched one by one.

[0105] Based on the above analysis, in the fiber-finding system provided in the embodiment of the present application, a signal detector 101 is provided in the fiber-finding device 11, and the signal detector 101 includes at least one detection part 1011. During the fiber-finding process, the detection part 1011 in the signal detector 101 can be clamped in the signal detection area 201 of the optical fiber 200, and a fiber-finding signal can be added to the signal input area 202 of the optical fiber to be found. When the amplitude of the change in the optical signal intensity of the detection part 1011 exceeds a set threshold, the signal detector 101 can send the identification information of the detection part 1011 to the processing device 12, and the processing device 12 performs data processing, and can match the port information of the first end A of the optical fiber to be found with the port information of the second end Z. Thus, the port information of the two ends of the optical fiber 200 can be matched quickly and accurately, and there is no need to pull out the optical fiber 200, which will not affect the connection relationship between the optical fiber 200 and other devices, and there is no need to interrupt the existing network service.

[0106] In addition, the fiber-finding signal can cause the intensity of the optical signal transmitted in the optical fiber 200 to change. In this way, by detecting the optical signal intensity of the signal detection area 201 of the optical fiber 200 through the detection unit 1011 and judging whether the change amplitude of the optical signal intensity exceeds the set threshold, the port information of the second end Z of the optical fiber to be found can be determined, and the port information of the first end A of the optical fiber 200 can be matched with the port information of the second end Z. In the fiber-finding process, the intensity change of the optical signal transmitted by the optical fiber 200 is used for fiber-finding. The transmission distance of the business light transmitted in the optical fiber 200 is relatively long, generally 40km to 80km. Therefore, the fiber-finding distance is basically consistent with the transmission distance of the business light. The fiber-finding distance in the embodiment of the present application is relatively long, generally up to 20km, or even up to 40km to 80km, which can realize cross-station detection of optical fibers.

[0107] In some embodiments of the present application, when traffic light is transmitted in an optical fiber, fiber tracing can be performed using changes in the intensity of the optical signal transmitted by the optical fiber 200. Specifically, the optical fiber to be traced can be controlled to generate a macrobend of a set degree in the signal input region 202. For example, the radius of the macrobend can be approximately 5.9 mm. This causes the optical fiber to be traced to generate leakage light in the signal input region 202, thereby causing a certain degree of intensity attenuation of the optical signal transmitted in the optical fiber to be traced (i.e., causing the intensity of the optical signal transmitted in the optical fiber to be traced to vary), thereby applying a fiber tracing signal to the signal input region 202. The detection unit 1011 is clamped to the signal detection region 201 of the optical fiber 200, and can cause the optical fiber 200 to generate a macrobend of a set degree in the signal detection region 201. For example, the radius of the macrobend can be approximately 5.9 mm, causing the optical fiber to generate leakage light in the signal detection region 201. If the signal input region 202 of the optical fiber 200 is subjected to a macrobend of a set degree, the intensity of the optical signal transmitted in the optical fiber 200 will decrease, and the intensity of the leakage light from the optical fiber 200 in the signal detection region 201 will also decrease. Therefore, by detecting the leakage light intensity of the optical fiber 200 in the signal detection area 201 (i.e., detecting the optical signal intensity of the signal detection area 201 of the optical fiber 200), and determining whether the change amplitude of the leakage light intensity exceeds the set threshold, it is possible to determine whether the optical fiber 200 is the optical fiber to be found.

[0108] During the fiber search process, the fiber search signal can cause the optical signal transmitted in the optical fiber 200 to change by about 1 dB, that is, the fiber search process has little impact on the optical signal in the optical fiber to be searched, and the fiber search process will not affect the existing network services.

[0109] In specific implementation, a variety of methods can be used to apply the fiber-searching signal to the signal input area 202 of the optical fiber to be searched. Several methods are described below with examples.

[0110] Method 1:

[0111] Continuing with reference to Figures 1 and 2, the fiber-finding device 11 may further include a signal generator 102, which is configured to be clamped to a signal input area 202 of any optical fiber 200 (e.g., the leftmost optical fiber 200 in Figure 2) and apply a fiber-finding signal to the signal input area 202 of the clamped optical fiber 200. The fiber-finding signal is configured to cause an intensity change in the optical signal transmitted in the optical fiber 200, wherein the signal input area 202 is located near the first end A of the optical fiber 200. In this embodiment of the present application, the fiber-finding device 11 may include one or more signal generators 102.

[0112] During the fiber-searching process, the signal generator 102 can be clamped in the signal input area 202 of the optical fiber to be searched, so that the optical fiber to be searched generates a macrobend of a set degree in the signal input area 202, so that the optical fiber to be searched generates leakage light in the signal input area 202, and then the intensity of the optical signal transmitted in the optical fiber to be searched is attenuated, thereby realizing the application of the fiber-searching signal to the signal input area 202.

[0113] Method 2:

[0114] The signal input area 202 of the optical fiber to be found can be manually bent to cause the optical fiber to be found to generate a macrobend of a set degree in the signal input area 202, so that the optical fiber to be found generates leakage light in the signal input area 202, and then the intensity of the optical signal transmitted in the optical fiber to be found is attenuated, thereby realizing the application of the fiber-seeking signal to the signal input area 202.

[0115] In other embodiments of the present application, when no service light is transmitted in the optical fiber to be found, a fiber search signal can be injected into the first end A of the optical fiber to be found. For example, simulated service light or an optical signal of another wavelength band (e.g., red light) can be injected into the first end A of the optical fiber to be found to increase the intensity of the optical signal transmitted in the optical fiber to be found. The detection unit 1011 is clamped in the signal detection area 201 of the optical fiber 200, and can cause the optical fiber 200 to generate a macrobend of a set degree in the signal detection area 201. For example, the radius of the macrobend can be about 5.9 mm, causing the optical fiber to generate leakage light in the signal detection area 201. If the fiber search signal is injected into the first end A of the optical fiber 200, the intensity of the optical signal transmitted in the optical fiber 200 will increase, and the leakage light intensity of the optical fiber 200 in the signal detection area 201 will also increase accordingly. Therefore, by detecting the leakage light intensity of the optical fiber 200 in the signal detection area 201 (i.e., detecting the optical signal intensity in the signal detection area 201 of the optical fiber 200) and determining whether the change in the leakage light intensity exceeds a set threshold, it can be determined whether the optical fiber 200 is the optical fiber to be found.

[0116] During specific implementation, in order to prevent the optical signal intensity change caused by normal business interaction or manual combing of optical fibers from causing misoperation of the fiber-finding device, the threshold value can be set to a value greater than the optical signal intensity change value caused by normal business interaction or manual combing of optical fibers. For example, the threshold value can be set to be greater than 0.2dB, for example, it can be set to a value such as 0.5dB, 0.6dB or 1dB. Of course, the value of the threshold value cannot be too large to prevent the inability to determine the optical fiber to be found due to the setting of the threshold value being too large. The specific value of the threshold value can be set according to the actual application scenario, and is not limited here.

[0117] Furthermore, in some embodiments of the present application, as shown in Figures 1 and 2 , the fiber-finding system may further include a fiber management platform 13. The fiber management platform 13 is configured to receive and store pairing information sent by the processing device 12; the pairing information includes port information of the first end A and the second end Z of the optical fiber 200 to be found. In a specific implementation, after matching the port information of the second end Z with the port information of the first end A of the optical fiber to be found, the processing device 12 may send the matched pairing information of the optical fiber 200 to the fiber management platform 13. The fiber management platform 13 may store the pairing information of multiple optical fibers 200, thereby enabling digital management of the optical fibers 200.

[0118] In a possible implementation, the signal detector 101 may communicate directly with the processing device 12 , that is, the signal detector 101 may directly send identification information of the target detection unit 1011 to the processing device 12 .

[0119] In another possible implementation, the signal detector 101 can communicate indirectly with the processing device 12. Specifically, the signal detector 101 can be used to send identification information of the target detection unit 1011 whose optical signal intensity change amplitude exceeds a set threshold to the optical fiber management platform 13. The optical fiber management platform 13 can also be used to receive the identification information of the target detection unit 1011 and send the received identification information of the target detection unit 1011 to the processing device 12. In other words, the optical fiber management platform 13 can also play a role in information transmission. The signal detector 101 can send the identification information of the target detection unit 1011 to the processing device 12 through the optical fiber management platform 13, so that the processing device 12 determines the port information of the second end Z of the optical fiber to be found based on the received identification information of the target detection unit 1011 and a preset correspondence, matches the port information of the second end Z of the optical fiber to be found with the pre-acquired port information of the first end A of the optical fiber to be found, and sends the matched pairing information to the optical fiber management platform 13.

[0121] The basic structure of the fiber-finding system in some embodiments of the present application is introduced above in conjunction with Figures 1 and 2. The fiber-finding method applied to the above-mentioned fiber-finding system is introduced in detail below in conjunction with the accompanying drawings.

[0122] FIG3 is an interactive schematic diagram of a fiber-finding method provided in an embodiment of the present application. As shown in FIG3 , the fiber-finding method applied to a fiber-finding system provided in an embodiment of the present application may include:

[0123] S301: The fiber-finding device sends identification information of a target detector whose optical signal intensity variation exceeds a set threshold to the processing device. Step S301 is executed in the signal detector of the fiber-finding device, that is, the signal detector sends the identification information of the detector to the processing device.

[0124] S302, the processing device determines the port information of the second end of the optical fiber to be found based on the received identification information of the target detection unit and a preset correspondence relationship, where the optical fiber to be found is one of the multiple optical fibers, and the correspondence relationship is a one-to-one correspondence between the identification information of the multiple detection units and the port information of the second ends of the multiple optical fibers;

[0125] S303. The processing device matches the port information of the second end of the optical fiber to be found with the port information of the first end of the optical fiber to be found obtained in advance; the optical fiber to be found is an optical fiber to which a fiber-seeking signal is applied at the first end, and the fiber-seeking signal is used to cause the intensity of the optical signal transmitted in the optical fiber to be found to change, and the amplitude of the change exceeds a set threshold.

[0126] 2 , when searching for multiple optical fibers 200 , a signal detector 101 can be installed at the second end Z of each optical fiber 200 . Specifically, a detection unit 1011 can be clamped in the signal detection area 201 of each optical fiber 200 , and the corresponding relationship between the identification information of the multiple detection units 1011 and the port information of the second end Z of the multiple optical fibers 200 is pre-stored in the processing device 12 . Then, one optical fiber 200 is selected from the multiple optical fibers 200 as the optical fiber to be searched, the port information of the first end A of the optical fiber to be searched is stored in the processing device 12 , and a search signal is applied to the signal input area 202 of the optical fiber to be searched. Since the signal detector 101 can execute the above-mentioned step S301 and the processing device 12 can execute the above-mentioned steps S302 and S303 , the fiber search method provided by the embodiment of the present application can quickly and accurately match the port information at both ends of the optical fiber. In addition, by using the change in the intensity of the optical signal transmitted by the optical fiber for fiber search, the fiber search distance is relatively long, generally up to 20 km, or even up to 40 km to 80 km, and cross-station detection of the optical fiber can be achieved.

[0127] Further, with continued reference to FIG3 , the fiber-finding method in the embodiment of the present application may further include:

[0130] In an embodiment of the present application, the processing device can send the pairing information of the matched optical fibers to the optical fiber management platform, and the optical fiber management platform can store the pairing information of multiple optical fibers, thereby realizing digital management of the optical fibers.

[0131] In a possible implementation, as shown in FIG3 , the fiber-finding device may communicate directly with the processing device, that is, the fiber-finding device may directly send identification information of the target detection unit to the processing device.

[0132] FIG4 is another interactive diagram of the fiber-finding method provided in an embodiment of the present application. As shown in FIG4 , in another possible implementation, the fiber-finding device may communicate indirectly with the processing device. The above step S301 may specifically include:

[0133] S3011, the fiber-finding device sends identification information of the target detection unit to the optical fiber management platform;

[0134] S3012: The optical fiber management platform receives identification information of the target detection unit, and sends the received identification information of the target detection unit to the processing device.

[0135] That is to say, the optical fiber management platform can also play the role of information transmission. The fiber-finding device can send the identification information of the target detector to the processing device through the optical fiber management platform, so that the processing device can determine the port information of the second end of the optical fiber to be found based on the received identification information of the target detection part and the preset correspondence, match the port information of the second end of the optical fiber to be found with the pre-acquired port information of the first end of the optical fiber to be found, and send the matched pairing information to the optical fiber management platform.

[0136] Based on the same technical concept, the embodiment of the present application further provides a processing device.

Specifically, a detector 1011 can be clamped in the signal detection area 201 of each optical fiber 200, and the correspondence between the identification information of the multiple detectors 1011 and the port information of the second ends Z of the multiple optical fibers 200 is pre-stored in the processing device 12. Then, one optical fiber 200 is selected from the multiple optical fibers 200 as the optical fiber to be searched, the port information of the first end A of the optical fiber to be searched is stored in the processing device 12, and a search signal is applied to the signal input area 202 of the optical fiber to be searched. The signal detector 101 can compare the variation in the optical signal intensity detected by each detector 1011 with a set threshold value, and send the identification information of the target detector whose optical signal intensity variation exceeds the set threshold value to the processing device 12. By setting a transceiver unit 121 and a processing unit 122 in the processing device 12, the port information of the first end A of the optical fiber to be found can be matched with the port information of the second end Z. Therefore, the processing device 12 provided in the embodiment of the present application can quickly and accurately match the port information at both ends of the optical fiber.

[0140] In some embodiments of the present application, the processing device 12 may further include a storage unit 123. The transceiver unit 121 may further be configured to receive port information of the first end of the optical fiber to be found, and the processing unit 122 may further be configured to store the port information of the first end of the optical fiber to be found received by the transceiver unit 121 in the storage unit 123. By providing the storage unit 123 in the processing device 12, the port information of the first end of the optical fiber to be found may be stored. After the processing unit 122 determines the port information of the second end of the optical fiber to be found, it may read the port information of the first end of the optical fiber to be found stored in the storage unit 123, thereby facilitating matching of the port information of the two ends of the optical fiber to be found.

[0141] Furthermore, in this embodiment of the present application, the transceiver unit 121 can also be used to send pairing information to the fiber management platform 13; the pairing information includes the port information of the first end and the port information of the second end of the optical fiber to be found. The transceiver unit 121 can send the pairing information of the matched optical fibers to the fiber management platform, which can store the pairing information of multiple optical fibers, thereby realizing digital management of optical fibers.

[0142] Based on the same technical concept, the embodiment of the present application also provides a fiber-finding method applied to the above-mentioned processing device. FIG6 is a flow chart of the fiber-finding method provided in the embodiment of the present application. As shown in FIG6 , the fiber-finding method applied to the above-mentioned processing device in the embodiment of the present application may include:

[0143] S401, receiving identification information of a target detection unit sent by a signal detector;

[0144] S402, determining port information of the second end of the optical fiber to be found based on the received identification information of the target detection unit and a preset correspondence relationship, where the optical fiber to be found is one of the multiple optical fibers, and the correspondence relationship is a one-to-one correspondence between the identification information of the multiple detection units and the port information of the second ends of the multiple optical fibers;

[0145] S403. Match the port information of the second end of the optical fiber to be found with the port information of the first end of the optical fiber to be found obtained in advance; the optical fiber to be found is an optical fiber to which a fiber-seeking signal is applied at the first end, and the fiber-seeking signal is used to cause the intensity of the optical signal transmitted in the optical fiber to be found to change, and the amplitude of the change exceeds a set threshold.

[0146] 2 , when searching for multiple optical fibers 200, a signal detector 101 can be installed at the second end Z of each optical fiber 200. Specifically, a detector 1011 can be clamped in the signal detection area 201 of each optical fiber 200, and the correspondence between the identification information of the multiple detectors 1011 and the port information of the second ends Z of the multiple optical fibers 200 is pre-stored in the processing device 12.

The signal detector 101 can compare the variation in the optical signal intensity detected by each detector 1011 with a set threshold and send the identification information of the target detector whose optical signal intensity variation exceeds the set threshold to the processing device 12. Because the processing device 12 can perform the above steps S401, S402, and S403, the fiber-searching method provided in the embodiments of the present application can quickly and accurately match the port information at both ends of the optical fiber.

[0147] Further, with continued reference to FIG6 , the fiber-finding method applied to the above-mentioned processing device in the embodiment of the present application may further include:

[0148] S404. Send pairing information to the optical fiber management platform; wherein the pairing information includes port information of the first end and port information of the second end of the optical fiber to be found.

[0149] In an embodiment of the present application, the processing device can send the pairing information of the matched optical fibers to the optical fiber management platform, and the optical fiber management platform can store the pairing information of multiple optical fibers, thereby realizing digital management of the optical fibers.

[0150] In a possible implementation, before matching the port information of the second end of the optical fiber to be found with the pre-acquired port information of the first end of the optical fiber to be found, the following steps may be further included:

[0151] The port information of the first end of the optical fiber to be found is received and stored. In this way, the port information of the first end of the optical fiber to be found is known, which is convenient for matching with the port information of the second end of the optical fiber to be found that is subsequently determined, so as to achieve matching of the port information of both ends of the optical fiber to be found.

[0152] In one possible implementation, the port information of the first end of the optical fiber to be found can be input into the processing device. For example, when the processing device is a mobile terminal such as a mobile phone or a tablet computer, an input box can be displayed in the processing device, and the port information of the first end of the optical fiber to be found can be entered through the input box. Of course, other methods can also be used to input the port information of the first end of the optical fiber to be found into the processing device, which is not limited here. In another possible implementation, when the processing device is a mobile terminal such as a mobile phone or a tablet computer, the port information of the first ends of multiple optical fibers can be pre-stored in the processing device, and a selection box can be displayed in the processing device, and each option in the selection box corresponds to the port information of the first end of an optical fiber. The user can select the port information of the first end of the optical fiber to be found in the selection box displayed by the processing device, and the processing device stores the port information of the selected first end of the optical fiber to be found. Afterwards, the user applies a fiber-seeking signal to the signal input area of ​​the optical fiber to be found according to the port information of the first end of the selected optical fiber to be found. The specific structure of the fiber-seeking device in the embodiment of the present application is described in detail below in conjunction with the accompanying drawings.

[0153] Figure 7 is a structural schematic diagram of the signal generator in an embodiment of the present application. As shown in Figure 7, the signal generator 102 may include: a first clamping member 1021, the first clamping member 1021 is used to clamp the signal input area 202 of any optical fiber 200, so that the clamped optical fiber 200 produces a macrobend of a set degree, so that the optical fiber 200 produces leakage light in the signal input area 202, so as to apply a fiber-seeking signal to the signal input area 202.

[0154] During the fiber-searching process, the first clamping member 1021 of the signal generator 102 can be clamped in the signal input area 202 of the optical fiber to be searched, so that the optical fiber to be searched generates a macrobend of a set degree in the signal input area 202. For example, the radius of the macrobend can be around 5.9 mm, so that the optical fiber to be searched generates leakage light in the signal input area 202, and then the intensity of the optical signal transmitted in the optical fiber to be searched is attenuated, thereby realizing the application of a fiber-searching signal to the signal input area 202 of the optical fiber to be searched.

[0155] In one possible implementation, the first clamping member 1021 may include a slot U1 and a sliding cover Q1. The signal input area 202 of the optical fiber 200 may be placed within the slot U1, and the sliding cover Q1 may be controlled to cooperate with the slot U1 to induce a macrobend in the optical fiber 200. In a specific implementation, a slide rail may be provided within the signal generator 102, along which the sliding cover Q1 can slide. The sliding cover Q1 can be pushed to slide, thereby cooperating with the slot U1 to induce a macrobend in the optical fiber 200. Alternatively, a button may be provided within the signal generator 102 to control the sliding of the sliding cover Q1, thereby cooperating with the slot U1 to induce a macrobend in the optical fiber 200. Alternatively, a bolt may be provided within the signal generator 102 to drive the movement of the sliding cover Q1, thereby cooperating with the slot U1 to induce a macrobend in the optical fiber 200. Of course, other methods for controlling the sliding of the sliding cover Q1 may also be employed, and these are not exemplified here. In one possible implementation, the slider Q1 can be configured to have an arc shape. Pressing the slider Q1 can cause the slider Q1 to move in the direction indicated by the arrow in the figure. In a specific implementation, the signal input area 202 of the optical fiber 200 can be placed within the slot U1. Then, pressing the slider Q1 causes one end of the slider Q1 to move to the position of the slot U1. The slider Q1 cooperates with the slot U1 to cause the optical fiber 200 to undergo a macrobend of a predetermined degree. FIG7 illustrates a curved slot U1 as an example. In a specific implementation, the slot U1 can also be linear, or it can be other curved shapes, without limitation.

[0156] In another possible implementation, the first clamping member may also be a fixture. During the fiber search process, the fixture can be opened to place the optical fiber to be searched within the fixture. The fixture is then closed to cause a macrobend of a predetermined degree to be generated in the optical fiber. Of course, the first clamping member in the embodiment of the present application may also be implemented in other ways, which will not be exemplified here.

[0157] Further, continuing to refer to Figure 7, the signal generator 102 may also include: a signal source 1022 for providing a fiber-finding signal, and the signal source 1022 can be used to inject a fiber-finding signal into the first end A of the optical fiber when no business light is transmitted in any optical fiber, so as to apply the fiber-finding signal to the optical fiber to be found. Specifically, the signal source 1022 can generate analog business light or an optical signal of other wavelengths (such as red light) as a fiber-finding signal. By injecting a fiber-finding signal into the first end A of the optical fiber to be found, the intensity of the optical signal transmitted in the optical fiber to be found can be increased. Therefore, by detecting the optical signal intensity of the optical fiber 200 in the signal detection area 201 through the signal detector 101, and judging whether the change amplitude of the optical signal intensity exceeds the set threshold, it is possible to judge whether the optical fiber 200 is the optical fiber to be found, so as to match the port information at both ends of the optical fiber to be found.

[0158] FIG8 is a schematic diagram of the structure of a signal detector in an embodiment of the present application. As shown in FIG8 , the signal detector 101 may include: at least one detection unit 1011, a first processing module 1012, and a communication module 1013. The first processing module 1012 is used to compare the amplitude of the change in the optical signal intensity detected by each detection unit 1011 with a set threshold value to determine the target detection unit, which is the detection unit 1011 whose amplitude of the change in the optical signal intensity in the signal detection area exceeds the set threshold value. The communication module 1013 is used to send the identification information of the target detection unit 1011 to the processing device. In a specific implementation, the first processing module 1012 can be electrically connected to each detection unit 1011 in the signal detector 101.

[0159] Optionally, the communication module 1013 may be a device with communication function, such as a Bluetooth module, a SIM card, etc.

[0160] FIG9 is another schematic diagram of the structure of a signal detector according to an embodiment of the present application. As shown in FIG9 , the signal detector 101 may include multiple detection unit groups 1011m, and each detection unit group 1011m may include multiple detection units 1011. FIG9 illustrates an example in which the signal detector 101 includes three detection unit groups 1011m, each of which includes six detection units 1011. In a specific implementation, the number of detection unit groups 1011m and the number of detection units 1011 in each detection unit group 1011m may be set according to actual needs, and are not limited here.

[0161] Continuing with reference to Figure 9, the signal detector 101 may also include: multiple second processing modules 1014, each detection unit group 1011m is electrically connected to a second processing module 1014, the second processing module 1014 is used to compare the change amplitude of the optical signal intensity detected by each detection unit 1011 in the connected detection unit group 1011m with the set threshold, determine the target detection unit, and send the identification information of the target detection unit 1011 to the first processing module 1012; wherein, the target detection unit 1011 is the detection unit 1011 whose optical signal intensity change amplitude exceeds the set threshold in the signal detection area 201. In an embodiment of the present application, by dividing the multiple detection units 1011 in the signal detector 101 into multiple detection unit groups 1011m, and setting a second processing module 1014 corresponding to the multiple detection unit groups 1011m, the second processing module 1014 processes the detection data generated by each detection unit 1011 in the corresponding detection unit group 1011m, and sends the processing result (i.e., the identification information of the detection unit 1011 that detects that the change in the light signal intensity exceeds the set threshold) to the first processing module 1012, which can reduce the data processing amount of the first processing module 1012 and improve the data processing speed.

[0162] Figure 10 is another schematic diagram of the structure of a signal detector according to an embodiment of the present application. As shown in Figure 10, the detection unit may include a second clamping member P and a light sensor (not shown). The second clamping member P is used to clamp the signal detection region 201 of any optical fiber 200 and induce a macrobend of a predetermined degree on the optical fiber 200, thereby causing the optical fiber 200 to generate light leakage in the signal detection region 201. The light sensor is located within the second clamping member P and is used to detect the intensity of the light leakage from the optical fiber 200 in the signal detection region 201.

[0163] During the fiber searching process, the second clamping part P of the detection part can be clamped in the signal detection area 201 of the optical fiber 200, so that the optical fiber 200 generates a macrobend of a set degree in the signal detection area 201. For example, the radius of the macrobend can be around 5.9 mm, so that the optical fiber 200 generates leakage light in the signal detection area 201. The photosensitive sensor located inside the second clamping part P can detect the intensity of the leakage light, thereby realizing the detection of the optical signal intensity of the signal detection area 201.

[0164] In one possible implementation, the second clamping member P may include a slot U2 and a sliding cover Q2. The slot U2 and the sliding cover Q2 cooperate to clamp the signal detection area 201 of the optical fiber 200 and induce a macrobend of a predetermined degree on the optical fiber 200. In a specific implementation, a slide rail may be provided in the detection unit, along which the sliding cover Q2 can slide. The sliding cover Q2 can be pushed to slide, thereby cooperating with the slot U2 to induce a macrobend on the optical fiber 200. Alternatively, a button may be provided in the detection unit to control the sliding cover Q2's movement, thereby controlling the sliding cover Q2's movement in conjunction with the slot U2 to induce a macrobend on the optical fiber 200. Alternatively, a bolt may be provided in the detection unit to drive the sliding cover Q2's movement, thereby cooperating with the slot U2 to induce a macrobend on the optical fiber 200. Of course, other methods for controlling the sliding cover Q2's movement are also possible, and these examples are not provided here.

[0165] Figure 11 is a schematic diagram of another structure of a signal detector according to an embodiment of the present application. As shown in Figure 11, multiple second clamping members P can share a common sliding cover Q2. In practice, multiple optical fibers 200 can be placed within multiple slots U2. The sliding cover Q2, shared by each slot U2, can then be controlled to slide, cooperating with each slot U2 to induce a macrobend of a predetermined degree on the multiple optical fibers 200. This allows simultaneous macrobending of multiple optical fibers 200, streamlining the process.

[0166] 10 and 11 illustrate the curved shape of the card slot U2 as an example. In a specific implementation, the shape of the card slot U2 may also be a straight line, or the shape of the card slot U2 may also be other curved shapes, which is not limited here.

[0167] In another possible implementation, the second clamping member may be a fixture, with the photosensor disposed within the fixture. During fiber tracing, the fixture can be opened to place the fiber to be traced within the fixture. The fixture can then be closed to induce a macrobend of a predetermined degree in the fiber. Of course, the second clamping member in the embodiment of the present application may also be implemented in other ways, which will not be further exemplified here.

Since the processing device can perform the above steps S501 to S503, the fiber-searching method provided in the embodiment of the present application can quickly and accurately match the port information at both ends of the optical fiber. In addition, the optical fiber management platform can perform the above step S504, thereby realizing digital management of optical fiber pairing information.
