Description

Technical Field

[0001] The present application belongs to the field of transmission and carrying technology, and in particular relates to a method, apparatus, device, storage medium and program product for optical cable fault detection. Background Art

[0002] Currently, when an optical cable in an optical cable transmission network fails, the fault point of the optical cable can be located based on a Geographic Information System (GIS).

[0003] Specifically, the network element management system in the optical cable transmission network obtains the signal loss information and fault point distance information sent by the starting transmission device and the end transmission device, and then determines whether an optical cable fault occurs based on the pre-stored topological connection relationship between the transmission devices and the signal loss information.

[0004] However, more than one optical cable may fail simultaneously in the transmission ring network. When multiple optical cables fail, the transmission equipment in the transmission network may be disconnected, making it impossible to send signal loss information. Therefore, the network element management system cannot obtain signal loss information and cannot accurately detect optical cable failures in the transmission network. Summary of the Invention

[0083] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is merely to provide a better understanding of the present application by illustrating the examples of the present application.

[0084] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or device comprising the element.

[0085] The current method for detecting the fault point of a transmission optical cable is as follows: after receiving the signal loss alarm information sent by the starting device, the network element management system determines whether it has also received the signal loss alarm information sent by the end device within a preset time period. When it is determined that both the starting device and the end device have sent signal loss alarm information to the network element management system, the network element management system determines that an optical cable fault has occurred, and further uses the optical cable break point location alarm to determine the specific location where the optical cable break occurred.

[0086] However, more than one optical cable may fail at the same time in the transmission ring network. When multiple optical cables fail, the transmission equipment in the transmission network may be disconnected, resulting in the inability to send signal loss information, such as Figure 1 As shown in the figure, a fault has occurred in the optical cable between node 1 and node 7, and a cable fault has occurred in the optical cable between node 3 and node 4. Node 7 and node 4 are out of the pipe and cannot send signal loss alarm information. Therefore, the network element management system cannot determine that a fault has occurred in the optical cable between node 1 and node 7, or in the optical cable between node 3 and node 4.

[0087] In order to solve the problems of the prior art, the embodiments of the present application provide a method, apparatus, device, storage medium and program product for detecting optical cable faults. The following first describes the method for detecting optical cable faults provided by the embodiments of the present application. Figure 2 As shown, the method is applied to a network element management system, and the method includes:

[0088] S201: Upon receiving optical cable break point location alarm information sent by a starting device port, obtain a plurality of preset key indicator information corresponding to each time point of the starting device port and the ending device port within a first preset time window.

[0089] The optical cable break location alarm information is used to carry the location information of the optical cable break. The starting device is the starting transmission device of the signal transmission, and the end device is the end transmission device of the signal transmission.

[0090] It is understandable that the minimum processing time of the network element management system is 1 millisecond. Therefore, the network element management system collects information sent by the end device and the starting device within the first preset time window according to the minimum processing time, and obtains preset key indicators from the received information.

[0091] The preset key indicators may be preset based on experience. In one example, the preset key indicators may be signal loss alarm information and network element disconnection alarm information.

[0092] S202: Traverse each time point within the first preset time window to determine whether multiple preset key indicator information within the preset time window meets the preset determination conditions corresponding to each preset key indicator.

[0093] The preset judgment condition is used to judge whether the optical cable between the starting device port and the end device port is interrupted.

[0094] S203: When multiple preset key indicator information within the first preset time window meets the preset judgment conditions corresponding to each preset key indicator, determine whether power outage alarm information sent by the computer room where the terminal device is located is received within the second preset time window.

[0095] It is understandable that in order to further improve the accuracy of fault detection and exclude signal reception anomalies caused by power outages in the computer room, it is possible to determine whether a power outage alarm message sent by the computer room is received within the second preset time window. If a power outage alarm message is received, it indicates that the signal reception anomaly is caused by a power outage in the computer room.

[0096] S204: If no power outage alarm information is received from the computer room where the end device is located within the second preset time window, it is determined that there is an optical cable fault between the starting device and the end device.

[0097] Using the above method, after receiving the optical cable break location alarm information sent by the starting device port, the network element management system triggers the fault detection process, obtains multiple preset key indicator information within the first preset time window, and determines whether the preset key indicator information corresponding to each time point meets the corresponding preset judgment conditions. When it is determined that the multiple preset key indicator information within the first preset time window all meet the corresponding preset judgment conditions, in order to further improve the accuracy of fault detection and eliminate signal reception anomalies caused by power outages in the computer room, the network element management system can further determine whether the power outage alarm information sent by the computer room where the terminal device is located is received within the second preset time window. If the power outage alarm information is not received, it indicates that the terminal device is operating normally. Therefore, it can be determined that the optical cable between the starting device and the terminal device has a break fault. In this way, combined with multiple preset key indicator information, it can be judged from multiple dimensions whether a break fault has occurred, thereby improving the accuracy of optical cable fault detection.

[0098] In some embodiments of the present application, the first preset time window is determined according to a dynamic time interval, and the dynamic time interval is determined by a set of historical optical cable fault information. Figure 3 Introduce the method of calculating the dynamic interval, such as Figure 3 As shown:

[0099] S301. Acquire multiple sets of optical cable fault information.

[0100] The optical cable fault information set includes the first timestamp when the starting device port sends the optical cable break location alarm information and the second timestamp when the network element management system determines that the optical cable fault occurs. Each set of optical cable fault information corresponds to a time point in the continuous time series.

[0101] S302: For each set of optical cable fault information, calculate the absolute value of the difference between the first timestamp and the second timestamp to obtain a time length.

[0102] like Figure 4 As shown, Figure 4 is a discrete function corresponding to a set of optical cable fault information. t0 is the moment when the NEMS receives the optical cable endpoint location alarm from the source device, and timi is the moment when the NEMS determines that an optical cable break has occurred. After a cable break is determined, the ordinate corresponding to that moment is set to 1, and all other moments are set to 0. The duration can be obtained by calculating the absolute value of the difference between timi and t0.

[0103] S303: Construct a gate function with the first timestamp as the center point and the time length as the boundary.

[0104] like Figure 5 As shown, Figure 5 The variable Δτ is shown as an example i g(Δτ i ) gate function, where Figure 4 The calculated time length Δτ provided by the embodiment shown i Based on this, we can construct a gate function with the first timestamp t0 as the center and the time length as the extension. Specifically, the discrete values in the horizontal coordinate timi and the symmetrical -timi range are set to 1, and the function values in the remaining positions are set to 0 to obtain the gate function.

[0105] S304 : Calculate the probability distribution function on the continuous time series for the gating function corresponding to each set of optical cable fault information.

[0106] Among them, after calculating the gate function corresponding to each set of optical cable fault information, g(Δτ i )=1, thus obtaining the probability distribution function on the continuous time series.

[0107] S305 , intercepting a target coordinate point on the probability distribution function that is greater than or equal to a preset fault demarcation accuracy rate.

[0108] S306: Determine a dynamic time interval according to the target coordinate point.

[0109] Specifically, such as Figure 6 As shown, Figure 6 The vertical axis represents the probability, and the horizontal axis represents the discrete time point. Figure 6 The coordinate points in the grid are intercepted to determine the intersection of the preset fault delimitation accuracy and the probability distribution function. The two intersection points are used to construct the time range interval to obtain Δτ1 and Δτ2. The maximum value of Δτ1 and Δτ2 is used as the dynamic time interval.

[0110] By adopting the method provided in the embodiment of the present application, the network element management system obtains historical data, namely, multiple sets of optical cable fault information, and constructs a gate function with the first timestamp as the center and the calculated time length as the boundary. The gate function can be used to characterize the time interval in which the network element management system determines that the optical cable fault occurs. In this way, by calculating the probability distribution function for each set of optical cable fault information, the network element management system can obtain the time concentration interval for determining the occurrence of the optical cable fault. Furthermore, based on the preset fault delimitation accuracy rate set by the user, the time concentration interval can be intercepted according to actual business needs, thereby ensuring the accuracy of the calculated dynamic time interval. This balances the accuracy and efficiency of the subsequent network element management system in determining the optical cable fault using the data within the first preset time window.

[0111] Regarding the above S306, determining the dynamic time interval according to the target coordinate point can be specifically implemented as follows:

[0112] Step A: According to the ordinate of the target coordinate point, respectively determine the first target coordinate point and the second target coordinate point corresponding to the minimum ordinate on both sides of the first timestamp.

[0113] Step B: Calculate the absolute value of the difference between the horizontal coordinate of the first target coordinate point and the first timestamp to obtain a first absolute value.

[0114] Step C: Calculate the absolute value of the difference between the horizontal coordinate of the second target coordinate point and the first timestamp to obtain a second absolute value.

[0115] Step D: taking the maximum value between the first absolute value and the second absolute value as the dynamic time interval.

[0116] Continuing the above Figure 6 In the example shown, after the first absolute value and the second absolute value are calculated, the dynamic time interval Δτ can be determined according to the following formula:

[0117]

[0118] Here, |Δτ1| is the first absolute value, and |Δτ2| is the second absolute value.

[0119] Using the method provided in an embodiment of the present application, after determining the target coordinate point, a first target coordinate point and a second target coordinate point located on either side of the first timestamp are determined within the target coordinate point, wherein the ordinate value of the first target coordinate point and the second target coordinate point is the minimum value among the target coordinate points. In this manner, the coordinates of the intersection of a preset fault delimitation accuracy and a probability distribution function can be determined using the first target coordinate point and the second target coordinate point. Furthermore, by calculating the first absolute value and the second absolute value and determining the maximum value between them as the dynamic time interval, detection accuracy is improved while ensuring the efficiency of the network element management system in detecting optical cable faults.

[0120] Based on the dynamic time interval obtained by the above calculation, the above S201, when receiving the optical cable break point location alarm information sent by the starting device port, obtains a plurality of preset key indicator information corresponding to each time point of the starting device port and the end device port within the first preset time window, which can be specifically implemented as follows:

[0121] Step 1: When the optical cable break point location alarm information sent by the starting device port is obtained, a dynamic time interval is obtained.

[0122] It should be noted that the above dynamic time interval can be updated according to a preset period.

[0123] Step 2: Construct a first preset time window based on the timestamp and dynamic time interval of the optical cable break point location alarm information sent by the starting device port.

[0124] Specifically, after determining the timestamp and dynamic time interval of the optical cable break location alarm information, the difference between the timestamp and the dynamic time interval, as well as the sum of the timestamp and the dynamic time interval, are calculated to obtain two time boundaries. These two time boundaries are the two boundaries of the first preset time window. In one example, the timestamp of the optical cable break location alarm information is t0, and the dynamic time interval is Δτ. Then, the constructed first preset time window is [t0-Δτ, t0+Δτ].

[0125] Step 3: Obtain multiple preset key indicator information corresponding to each time point in the first preset time window.

[0126] Using the method provided in the embodiment of the present application, a first preset time window is constructed based on the dynamic time interval calculated above. Since the dynamic time interval is calculated based on historical data, after determining the timestamp of the optical cable break location alarm information, within the dynamic time interval, the network element management system can accurately and quickly make an optical cable fault judgment.

[0127] In some embodiments of the present application, for each time point, it is determined whether the time point meets the corresponding preset judgment condition based on multiple preset key indicator information of the time point. Specifically, the preset key indicator information of each time point can be represented by a judgment matrix to determine whether the time point meets the corresponding preset judgment condition. Based on this, Figure 7 As shown, for the above S202, traversing each time point within the first preset time window, judging whether the multiple preset key indicator information within the preset time window meets the preset judgment conditions corresponding to each preset key indicator, can be specifically implemented as follows:

[0128] S2021. For each time point, construct a judgment matrix corresponding to the time point.

[0129] The rows of the judgment matrix represent corresponding time points, and the columns of the judgment matrix represent different preset judgment conditions.

[0130] S2022. For a plurality of preset key indicator information corresponding to each time point, if the preset key indicator information meets the corresponding target preset judgment condition, set the column corresponding to the target preset judgment condition in the judgment matrix to 1.

[0131] S2023. For a plurality of preset key indicator information corresponding to each time point, if the preset key indicator information does not meet the corresponding target preset judgment condition, set the column corresponding to the target preset judgment condition in the judgment matrix to 0.

[0132] In one example, for each time point, a judgment matrix corresponding to that time point is constructed. This judgment matrix can be a one-row, five-column matrix, for example, [1 1 1 1 1], where the first 1 indicates that the preset key indicator information meets the preset judgment condition corresponding to that column. In this way, after constructing the judgment matrix corresponding to each time point, the multiple judgment matrices can be sorted according to the corresponding time points to construct a judgment matrix corresponding to the first preset time window.

[0133] By using the method provided in the embodiment of the present application, after obtaining multiple preset key indicator information within the first preset time window, a judgment matrix corresponding to each time point can be constructed based on the number of preset judgment conditions, wherein each column corresponds to a preset judgment condition. According to the judgment matrix corresponding to each time point, the time point that meets the preset judgment condition within the first preset time window can be accurately determined.

[0134] In an embodiment of the present application, the preset key indicator information includes signal loss alarm information sent by the starting device port, optical cable break point location alarm information sent by the end device port, signal loss alarm information, and network element disconnection alarm information. The above-mentioned determination of multiple preset key indicator information within the preset time window and whether the preset judgment conditions corresponding to each preset key indicator are satisfied can be implemented as follows:

[0135] When a signal loss alarm is received from a source device port, the corresponding column in the judgment matrix is set to 1. When an optical cable break location alarm is received from a destination device port, the corresponding column in the judgment matrix is set to 1. When a signal loss alarm is received from a destination device port, the corresponding column in the judgment matrix is set to 1. When a network element disconnection alarm is received from a destination device port, the corresponding column in the judgment matrix is set to 1.

[0136] The preset judgment condition is whether the network element management system receives the corresponding information. If the corresponding information is received, the element value of the corresponding column is set to 1; if the corresponding information is not received, the element value of the corresponding column is set to 0.

[0137] In this way, the network element management system can determine whether there is an optical cable interruption fault from multiple dimensions by determining whether the preset key indicator information is received within the first preset time window, thereby improving the accuracy of fault detection.

[0138] After constructing the judgment matrix corresponding to each time point, the judgment matrix corresponding to each time point is used to determine whether the preset judgment condition is satisfied within the first preset time window. Specifically, in the above S204, if no power outage alarm information is received from the computer room where the end device is located within the second preset time window, before determining that there is an optical cable fault between the starting device and the end device, the method further includes:

[0139] For each preset judgment condition, obtain the target element value of the column corresponding to the preset judgment condition in each judgment matrix; sum the target element values corresponding to each judgment matrix to obtain the total element value; when the total element value is greater than the preset threshold, determine whether the multiple preset key indicator information within the first preset time window meets the preset judgment condition corresponding to each preset key indicator.

[0140] Specifically, after constructing the judgment matrix corresponding to each time point, each judgment matrix can be sorted in the order of the time points to construct an n×m matrix, where n is the number of time points and m is the number of preset judgment conditions. In this way, for the above n×m matrix, the elements of each column can be summed to obtain the total element value corresponding to each column. Among them, based on the above setting of the element value of the judgment matrix, when the preset key indicator information corresponding to a certain time point meets the preset judgment condition, the calculated total element value corresponding to the preset judgment condition is greater than 1, and therefore, it can be determined that an optical cable fault has occurred. In this way, by calculating the total element value corresponding to each column, it is possible to determine whether an optical cable fault exists through multiple dimensions within the first preset time window, thereby improving the accuracy of fault detection.

[0141] The following combination Figure 8 Introducing a method for detecting optical cable faults provided by an embodiment of the present application, such as Figure 8 As shown, the method includes:

[0142] S801. The A-end device port sends an optical cable endpoint location alarm.

[0143] The A-end device is the starting point device in the above embodiment.

[0144] Specifically, after the network element management system receives the optical cable end position alarm information sent by the A-end device port, it can mark T A_FIBER_BREAK_POS =1, that is, the element value of the corresponding column in the judgment matrix is set to 1. The network element, network element port, and cable break location information in the optical cable endpoint location alarm information are extracted. This is used to subsequently draw the transmission optical path and mark the interrupted bearer segment.

[0145] In an example, the information such as the network element, network element port, and optical cable break point location in the extracted optical cable endpoint location alarm information can be cached in the structure shown in Table 1:

[0146] Table 1

[0147]

[0148] S802: Extract port topology information of the A-end device and the Z-end device.

[0149] A topology database is pre-stored in the network element management system, and the topology database can be used to store the topological relationship between different transmission devices.

[0150] In one example, the optical path information table in the topology database is queried using the A-end device port or the Z-end device port to obtain unique optical path information. For example, if "network element port" = "72-1005-AA-HJ-1-1a-4-TN11SFIU(TN11SFIU01)-1" is queried for optical path information, information such as the optical path name, A-end device, A-end device port, Z-end device, and Z-end device port can be extracted. This is shown in Table 2:

[0154] If yes, execute S804; if no, end the process.

[0155] If the signal loss alarm information sent by the A-end device port is received within the first preset time window, the T A_R_LOS =1, that is, the element at the corresponding position in the judgment matrix is set to 1, otherwise it is set to 0.

[0161] If yes, execute S807; if no, end the process.

[0163] S808. Determine whether the computer room where the Z-end device is located sends a power outage alarm message.

[0164] If yes, the process ends; if no, step S809 is executed.

[0165] S809: Determine that the optical cable at the AZ end is faulty.

[0166] According to the method provided in the embodiment of the present application, after receiving the optical cable break position alarm information sent by the starting device port, the network element management system triggers the fault detection process and obtains multiple preset key indicator information within the first preset time window, namely, optical cable break position alarm information, signal loss information, and network element disconnection alarm information. And it is judged whether the preset key indicator information corresponding to each time point meets the corresponding preset judgment conditions. When it is determined that the multiple preset key indicator information within the first preset time window all meet the corresponding preset judgment conditions, in order to further improve the accuracy of fault detection and eliminate the signal reception abnormality caused by power outage in the computer room, the network element management system can further judge whether the power outage alarm information sent by the computer room where the terminal device is located is received within the second preset time window. If the power outage alarm information is not received, it means that the terminal device is operating normally. Therefore, it can be determined that the optical cable between the starting device and the terminal device has a disconnection fault. In this way, combined with multiple preset key indicator information, it can be judged from multiple dimensions whether a disconnection fault has occurred, thereby improving the accuracy of optical cable fault detection.

[0167] After the above determination that an optical cable fault has occurred, the network element management system can also draw a transmission optical path based on the above multiple preset key indicator information. Figure 9 As shown, the method includes:

[0168] S901. Acquire optical cable segment information with a starting device as the starting point and an ending device as the ending point.

[0169] The optical cable segment information includes the name of the starting device, the name of the ending device, and the name of the optical cable segment.

[0170] Specifically, the network element management system can query the above-mentioned optical cable segment information from the preset database. Figure 10 As shown, Figure 10 An example query page is shown. By inputting the names of the starting device and the ending device, all optical cable segments associated with the optical path can be obtained, specifically information on 51 optical cable segments.

[0171] For each cable segment, the user can click on the corresponding cable segment to obtain detailed information about the cable segment, such as Figure 11 and Figure 12 As shown, Figure 11 and Figure 12 Detailed information of different fiber optic cable sections is shown as an example.

[0172] S902: Obtain optical cable laying information of each optical cable segment according to the optical cable segment information.

[0173] The optical cable laying information includes the location information of the sending device and the location information of the receiving device of each bearing segment in each optical cable segment. Each optical cable segment includes multiple bearing segments. Specifically, Figure 13 As shown, Figure 13 An example of a display page for optical cable laying information is shown, which includes the serial number corresponding to the optical cable laying information, and the location information of bearing point A and bearing point Z. Bearing point A is the starting device for data transmission, and bearing point Z is the end device for data transmission.

[0174] S903 : For each bearer segment, connect the sending device and the receiving device according to the location information of the sending device and the location information of the receiving device, and complete the drawing of the transmission optical path from the starting device to the end device.

[0175] The location information of the sending device is the location information of the aforementioned bearing point A, and the location information of the receiving device is the location information of the aforementioned bearing point Z. Specifically, the location information of the sending device and the location information of the receiving device can be longitude and latitude information.

[0176] In an example, assuming the longitude and latitude information of the sending device is (x1, y1) and the longitude and latitude information of the receiving device is (x2, y2), the longitude and latitude distance between the sending device and the receiving device can be calculated using the following formula, thereby achieving a connection between the sending device and the receiving device:

[0177] D = R*arccos(siny1*siny2+cosy1*cosy2cos(x1-x2)). R is the radius of the Earth, which is 6370 km.

[0178] For each bearer segment, the starting device and the ending device of the bearer segment are connected end to end according to the sequence number of the bearer segment, thereby obtaining a complete transmission optical path.

[0179] S904: Identify the bearer section with the optical cable fault in the transmission optical path according to the optical cable break point location alarm information sent by the starting device and the optical cable break point location alarm information sent by the end device.

[0180] It can be understood that the optical cable break location alarm information includes the distance from the optical cable break location to the starting device and the end device. After obtaining the distance of each bearing segment as mentioned above, the bearing segment with the interruption fault can be determined by accumulating the distance of each bearing segment and the distance from the optical cable break location to the starting device and the end device.

[0181] By adopting the method provided in the embodiment of the present application, when it is determined that an optical cable fault has occurred as mentioned above, the information of each optical cable segment and the optical laying information corresponding to each optical cable segment information are obtained from the preset database, and the starting point and end point of each load-bearing segment can be determined. By connecting the head and tail nodes of each load-bearing segment, the entire transmission optical path can be drawn.

[0182] It should be noted that the above optical installation information also includes the cable reel lengths of the receiving and transmitting devices of the load-bearing segment. Based on this, the distance of each load-bearing segment can be accurately calculated based on the cable reel lengths. Specifically, the distance of the load-bearing segment is calculated as follows:

[0183] For each load-bearing segment, the longitude and latitude distance is calculated based on the location information of the transmitting device and the receiving device; the sum of the longitude and latitude distance and the length of the optical cable reel is calculated to obtain the length corresponding to each load-bearing segment.

[0184] like Figure 14 As shown, Figure 14 The example shows the length of spare optical cable reserved for the sending device and receiving device of the load-bearing section. After the longitude and latitude distances of the sending device and the receiving device are calculated based on the location information of the sending device and the receiving device of the load-bearing section, in order to further improve the accuracy of the calculated distance of the load-bearing section, since a part of the optical cable will be reserved for backup in the sending device and the receiving device during the actual laying of the optical cable, the length of the optical cable reel is accumulated to obtain the longitude and latitude distances calculated above, and the length corresponding to each load-bearing section can be accurately obtained.

[0185] Based on the length of each carrying segment obtained by the above calculation, the distance information corresponding to the optical cable fault is carried in the optical cable break location alarm information sent by the starting device and the end device to verify the optical cable segment where the interruption occurs. Figure 15 As shown, the above S904, identifying the bearer section having the optical cable fault in the transmission optical path according to the optical cable break point location alarm information sent by the starting device and the optical cable break point location alarm information sent by the end device, can be implemented as follows:

[0186] S9041. Taking the starting device as the starting point, perform cumulative calculation on the length of the bearer segment on the transmission optical path to obtain a first cumulative calculation result.

[0187] S9042: Determine a first bearer section where the optical cable fault occurs based on the first distance information and the first accumulated calculation result in the optical cable break point location alarm information sent by the endpoint device.

[0188] S9043. Taking the end point device as the starting point, perform cumulative calculation on the length of the bearer segment on the transmission optical path to obtain a second cumulative calculation result.

[0189] S9044: Determine a second bearer segment where the optical cable fault occurs based on the second distance information and the second accumulated calculation result in the optical cable break point location alarm information sent by the endpoint device.

[0190] S9045: If the first bearing segment and the second bearing segment are the same bearing segment, mark the same bearing segment.

[0191] Using the method provided in the embodiments of the present application, the starting device first accumulates the lengths of the bearer segments of the transmission optical path to obtain a cumulative calculation result for each bearer segment. After the cumulative calculation for each bearer segment, the cumulative calculation result for that bearer segment is compared with the first distance information in the optical cable break location alarm information of the starting device, thereby determining the first bearer segment where the fault occurred from the starting device. Accordingly, the second bearer segment is calculated from the receiving device. If the first bearer segment and the second bearer segment are the same bearer segment, the failed bearer segment is verified from two directions, thereby marking the same bearer segment.
