[0047] 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.

[0048] The terms "first," "second," "third," and "fourth," etc., used in the specification, claims, and drawings of this application are used to distinguish different objects, not to describe a specific order. 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 includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or apparatuses.

[0049] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0050] In practical applications of optical cables, it is frequently necessary to monitor their operational status. Traditional equipment monitoring may involve multiple ports, each corresponding to a single optical fiber core. When an anomaly such as a break occurs in a cable bundle, the equipment needs to poll the abnormal fiber precisely to detect the problem. Monitoring equipment monitoring multiple ports is limited by physical hardware; only one port can be monitored at a time, necessitating port switching. In the event of a serious optical cable accident, the monitoring equipment should assist repair personnel in detecting abnormal fiber cores as quickly as possible. The relevant technology primarily uses a sequential polling method to monitor for anomalies. When an anomaly occurs in a fiber core at the end of the polling sequence, all optical cable ports must be polled before the abnormal core can be located. This method is time-consuming and inefficient in detecting abnormal fibers. For critical optical cables, every second of troubleshooting results in significant economic losses, making it crucial to shorten the time required to locate abnormal fiber cores.

[0051] To address the aforementioned issues, this application proposes a method, apparatus, equipment, and storage medium for detecting abnormal fiber cores in optical cables. In an optical cable, multiple fiber cores form a bundle, and multiple bundles form an optical cable. When the system manages information about the fiber cores, bundles, and optical cables, it can generate an optimal polling strategy based on existing optical cable detection equipment: polling each optical cable and each bundle in a skip-step manner. When a single situation such as a broken core, broken bundle, or broken cable occurs, it can be detected in the shortest possible time. Furthermore, the monitoring resources are concentrated into sufficiently small monitoring units, enabling rapid output of anomaly reports. The optical cable detection equipment includes optical cable line analysis instruments and optical cable sonar instruments, among others.

[0052] Figure 1 The flowchart of the method for detecting abnormal fiber cores in optical cables provided in the embodiments of this application is as follows: Figure 1 As shown, the method for detecting abnormal fiber cores in optical cables proposed in this application includes:

[0053] S101. Group and poll each optical cable under test;

[0054] The group polling process includes: detecting whether the first fiber core under test in the current optical cable under test is normal; if so, the first fiber core under test in the current optical cable under test is confirmed as the first normal fiber core, and the first fiber core under test in the next optical cable under test is detected, until all the first fiber cores under test are traversed; if not, the current optical cable under test is confirmed as an abnormal optical cable, and the group polling is stopped.

[0055] S102, Alternately poll each test tube in the abnormal optical cable.

[0056] The alternating polling process includes: detecting whether the second fiber core in the current test tube is normal; if so, confirming the second fiber core in the current test tube as the second normal fiber core, and detecting the second fiber core in the next test tube; if not, confirming the current test tube as an abnormal test tube, and detecting the second fiber core in the next test tube, until the second fiber core in each test tube has been detected.

[0057] S103. When all the test tubes in the abnormal optical cable are abnormal tubes, send optical cable disconnection information to the terminal.

[0058] S104. When some of the abnormal bundle tubes exist in the abnormal optical cable, the third fiber core to be tested in the abnormal bundle tube is detected in sequence to obtain the abnormal fiber core, and the information of the abnormal fiber core is sent to the terminal.

[0059] Before polling the optical cable, it is necessary to record the physical distribution information of the fiber cores, such as numbering the optical cable, bundle tube and fiber core respectively, and then the corresponding optical cable operation control system can control the operation of the optical cable, bundle tube and fiber core according to the number.

[0060] It should be noted that the abnormal optical cable mentioned in this embodiment specifically refers to an optical cable that cannot perform normal communication. The inability to perform normal communication includes abnormal communication rate, abnormal communication stability, and disconnection of the communication channel. In this embodiment, the abnormality of the optical cable includes at least the following possible situations: (1) Several fibers in the optical cable are abnormal, including but not limited to breakage, bending, or deformation; (2) Some bundle tubes in the optical cable are abnormal, including but not limited to breakage, bending, or deformation; (3) The entire optical cable is abnormal.

[0061] After polling each optical cable under test in groups in step S101, the method includes: if all of the bundle tubes of the abnormal optical cable are abnormal, sending the alarm information of the abnormal optical cable to the terminal.

[0062] Step S102, which involves alternating polling of each test tube in the abnormal optical cable, includes sequentially detecting each fiber core in the abnormal optical cable and sending the information of the detected faulty fiber core to the terminal. The information of the faulty fiber core includes the optical cable segment information and the tube information where the faulty fiber core is located. Specifically, it includes: performing communication tests on the first fiber core of the first tube; performing communication tests on the second fiber core of the second tube; performing communication tests on the third fiber core of the first tube; and performing communication tests on the fourth fiber core of the second tube. The first tube includes at least the first and third fiber cores, and the second tube includes at least the second and fourth fiber cores. The alternating polling provided in this embodiment is a group polling strategy. By managing the optical cable segment information, the composition of the optical fiber system is divided into at least three groups, such as optical cable, tube, and fiber core. The group with the largest coverage area is polled first, and then each group is polled and monitored sequentially according to its coverage area. This embodiment further binds the correlation between tubes and fiber cores to achieve precise control of the communication tests of tubes and fiber cores, and can quickly determine the location of the abnormal fiber core or tube in a highly efficient manner. The step of sequentially detecting the third fiber core to be tested in the abnormal bundle tube, obtaining the abnormal fiber core, and sending the information of the abnormal fiber core to the terminal further includes: detecting the abnormal bundle tube again, obtaining and sending secondary confirmation information to the terminal.

[0063] Optionally, in the step of sequentially detecting each fiber core in the abnormal optical cable and sending the information of the detected faulty fiber core to the terminal: sequentially detecting each fiber core in the abnormal optical cable to obtain the faulty fiber core; performing fault distance detection on the faulty fiber core to obtain first fault distance data; and generating information of the faulty fiber core based on the first fault distance data, the optical cable segment information and the bundle tube information where the faulty fiber core is located.

[0064] Since optical cables cover a wide area during actual installation, and repairs require manual intervention at the fault location after an anomaly occurs, incurring significant time and labor costs, it is crucial to minimize the error rate of optical cable anomaly location detection. Therefore, in this embodiment, after obtaining the location of the anomaly, the method further includes: performing a secondary confirmation of the location; and sending the location to a server or terminal. Specifically, the secondary confirmation in this embodiment may include: performing a communication test on the location of the anomaly; if a communication anomaly occurs, the current location is confirmed as the location of the anomaly. That is, after obtaining the location of the anomaly through steps S101-S103, a communication test is performed to confirm that an anomaly has indeed occurred at the current location, thus reducing the error rate of optical cable anomaly location detection.

[0065] In this embodiment, in the step of sequentially detecting the third fiber core to be tested in the abnormal bundle tube to obtain the abnormal fiber core, and sending the information of the abnormal fiber core to the terminal: the abnormal fiber core is subjected to fault distance detection to obtain second fault distance data; based on the second fault distance data and the optical cable segment information and bundle tube information where the abnormal fiber core is located, the information of the abnormal fiber core is generated.

[0066] Figure 2 The flowchart of the method for detecting abnormal fiber cores in optical cables provided in this application embodiment is applied to optical fiber testing, as follows: Figure 2 As shown, the specific workflow of the optical cable abnormal core detection method proposed in this application when applied to optical fiber testing is as follows:

[0067] Step 1: The device adopts a grouped polling strategy to perform daily polling.

[0068] Step 2: When polling detects a broken core, send the first alarm SMS to inform the detected broken core target.

[0069] Step 3: For the optical cable where the broken core is located, perform a loop polling of its multiple bundle tubes to determine if the optical cable is completely broken.

[0070] Step 4: If all the bundle tubes are disconnected, the optical cable is broken. If some bundle tubes are disconnected, the optical cable is not completely broken.

[0071] Step 5: If the fiber optic cable is broken, send an emergency SMS to the customer and confirm the breakage. If it is not a fiber optic cable breakage, further poll the fiber optic tube to determine whether the breakage is due to the fiber optic tube itself or a partial fiber core breakage.

[0072] Step 6: Send an SMS to the customer to inform them of the test results. If some fiber cores are broken, the specific fiber cores will also be notified to the customer via SMS.

[0073] Step 7: Confirm the alarm information again.

[0074] For example, when the optical cable abnormal core detection method provided in this application is applied to optical fiber inspection, and the optical cable system to be inspected includes optical cable A, optical cable B, and optical cable C, optical cable A includes bundle tubes A1 and A2, optical cable B includes bundle tubes B1 and B2, and optical cable C includes bundle tubes C1 and C2, and different bundle tubes have their own fiber cores, the specific workflow of the optical cable alternating polling in this embodiment is as follows:

[0075] (1) At the optical cable level, each optical cable is polled at least once.

[0076] The polling order is: fiber optic cable A, fiber optic cable B, fiber optic cable C, fiber optic cable A, fiber optic cable B, fiber optic cable C...

[0077] By polling each optical cable at least once, we can avoid polling port by port, which would prevent us from quickly traversing the defects of each optical cable. If an optical cable is broken, it can be detected quickly, and we can also make a preliminary detection of optical cables with abnormalities.

[0078] (2) At the bundle tube level, based on the optical cable polling, the bundle tubes of different optical cables use an alternating polling method.

[0079] The polling order is: bundle tube A1, bundle tube B1, bundle tube C1, bundle tube A2, bundle tube B2, bundle tube C2...

[0080] Step (2) Based on the polling of the bundle tubes, the method of alternating polling of different bundle tubes can detect the abnormal bundle tubes in a shorter time.

[0081] (3) At the core level, based on the polling of the bundle tube, the core of different bundle tubes is polled alternately.

[0082] The polling order is as follows: fiber core A11 contained in bundle tube A1, fiber core B11 contained in bundle tube B1, fiber core C11 contained in bundle tube C1, fiber core A22 contained in bundle tube A2, fiber core B22 contained in bundle tube B2, fiber core C22 contained in bundle tube C2, and so on.

[0083] By using alternating polling of the optical cable in this embodiment, and by strategically arranging ordinary polling and emergency response strategies, the detection time of abnormal fiber cores can be shortened at the implementation level. Problematic fiber cores can be detected in the shortest possible time, effectively mitigating losses from optical core accidents.

[0084] Furthermore, this application also provides an alarm emergency strategy for detecting fiber core anomalies. For example, when a polling operation detects an anomaly in fiber core A11, the polling logic is stopped, and an alarm SMS is sent to the server or user terminal stating, "Optical cable A-bunch A1-fiber core A11 has an anomaly; further verification is underway." Afterward, only the fiber optic cable itself is checked for breakage, and a breakage confirmation is quickly initiated with an average duration of 1 second. For example:

[0085] Optical cable A-bunch A1-core A11;

[0086] Optical cable A-bunch A2-core A21;

[0087] Optical cable A-bunch A3-core A31;

[0088] Optical cable A-bunch A4-core A41;

[0089] Optical cable A-bunch A5-core A51.

[0090] If all results after one round indicate a broken core, it means the optical cable is broken. Send an SMS: "Optical cable B has been broken; secondary confirmation is in progress."

[0091] The alarm and emergency response strategy provided in this embodiment can summarize the monitored abnormal locations and conditions of optical cables to user terminals or server cloud, so that users can know the location of the abnormality in the optical fiber system as soon as possible. At the same time, it is convenient to integrate optical fiber monitoring data into the server to form a monitoring map and other visual interfaces.

[0092] The broken core confirmation involves performing a communication test on the abnormal optical cable A-bunch A1-fiber core A11. If communication fails, the current location is determined to be the location where the abnormal optical cable has a broken core. Afterwards, an SMS message can be sent: "After secondary confirmation, optical cable B has been broken, and all its fiber cores have been broken."

[0093] If a section of the fiber optic cable's bundle tubes has a problem, then the problematic bundle tubes are polled to inspect the specific fiber cores. For example:

[0094] Optical cable A-bunch A1-core A11;

[0095] Optical cable A-bunch A1-core A12;

[0096] Optical cable A-bunch A1-core A13.

[0097] Send SMS notifications for polling results, for example: All fiber cores of a bundle tube are disconnected: "Optical cable A-bundle tube A1 is disconnected, and all its fiber cores are disconnected." Partial fiber core disconnection: "Fiber cores A11, A12, and A14 of optical cable segment A-bundle tube A1 are disconnected, while other fiber cores are normal."
