The step numbers in the following embodiments are provided for ease of description only and do not limit the order of the steps. The order of execution of the steps in the embodiments can be adaptively adjusted based on the understanding of those skilled in the art.

[0055] It should be noted that, although the functional modules are divided in the device schematic diagram and the logical order is shown in the flow chart, in some cases, the steps shown or described can be performed in a different order than the module division in the device or the order in the flow chart. The terms "first", "second", etc. in the specification and claims and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or precedence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0056] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application pertains. The terms used herein are for the purpose of describing the embodiments of this application only and are not intended to limit this application.

[0057] Some technical terms in this embodiment are explained below.

[0058] Optical Line Protection (OLP) network management: This device monitors OLP equipment in real time and collects alarm, configuration, and performance data. OLP is used in fiber optic communications to switch between primary and backup optical paths. It automatically identifies the optical signal status of the primary and backup fibers and instantly switches optical paths, preventing failures in the primary fiber optic cable and protecting normal communications. Optical line protection equipment provides real-time optical power monitoring, optical path switching, and alarm generation. The port pair and interface for establishing routing are transparent, and the switching routes are all established in the optical domain.

[0059] Transmission Equipment Network Management: This system monitors transmission equipment in real time and collects alarm, configuration, and performance data. Optical transmission equipment converts various signals into optical signals for transmission over optical fibers. Therefore, all modern optical transmission equipment utilizes optical cables. Commonly used optical transmission equipment includes optical terminals, optical transceivers, optical switches, PDH (Plesiochronous Digital Hierarchy), SDH (Synchronous Digital Hierarchy), and PTN (Packet Transport Network).

[0060] Transmission Integrated Network Management: This enables centralized management of transmission equipment and OLP equipment network elements, and completes the collection of alarm, performance, and configuration data. Based on the architecture of intelligent network management, the transmission integrated network management system can access the integrated network management systems of multi-vendor communication networks. By collecting and analyzing network configuration, alarm, performance, and other related data, the transmission integrated network management system implements functions such as comprehensive alarm monitoring, performance analysis and early warning, cross-vendor circuit management, network operation quality assessment, and intelligent network inspection. The transmission integrated network management supports docking with OSS systems such as resources, integrated alarms, and service assurance, enabling resource data correlation, auditing, and writeback, as well as alarm point output, alarm-to-service correlation, cutover management, and online optical cable monitoring. The transmission integrated network management system can conduct targeted and comprehensive monitoring and analysis of network operation status, effectively achieving intensive network management and providing practical support and assurance for network maintenance.

[0061] Long distance resource management system: It is a full-service long distance network resource information management system, which has the resource management functions of transmission trunk optical cable, system, device and service. The interface with the transmission integrated network management has been opened, and the name standard for data association between the OLP network management, the transmission device network management and the transmission integrated network management is provided.

[0062] OTS (Optical Transmission Section layer, optical transmission section layer): The transmission functions of the optical transmission section layer network include OTS path, OTS path terminal source, OTS path terminal sink, OTS network connection, OTS link connection, OTS subnet and OTS subnet connection. As the transmission entity of the optical transmission section, the OTS subnet provides network connection protection in the optical transmission section layer. The feature information is routed between the input terminal connection point and the output terminal connection point.

[0063] Referring to Figure 1 , Figure 1 The structure of the implementation environment in the embodiment of the application is shown in the schematic diagram. The transmission device network management is connected with the operation base through the I2 interface, the operation base is connected with the transmission integrated network management through the I1 interface, the transmission integrated network management obtains the data of the transmission device network through the operation base; the transmission integrated network management is connected with the optical line protection network management through the network interface to obtain the data of the optical line protection network management; the transmission integrated network management is connected with the long distance resource management system through the FTP (File Transfer Protocol, file transfer protocol) to obtain the data of the long distance resource management system; and the transmission integrated network management determines the fault optical cable section according to the obtained data.

[0064] Referring to Figure 2 , the embodiment of the application provides a method for positioning the fault of the optical cable, which is applied to the transmission integrated network management and includes the following steps S100 to S500.

[0065] S100, obtaining the first alarm information and the first performance data from the transmission device network management, obtaining the second alarm information and the second performance data from the optical line protection network management, and obtaining the network resource data from the long distance resource management system.

[0066] The first alarm information of the optical line related machine disk collected by the transmission device network management includes the optical amplifier disk (PA, BA, LA), the optical supervisory control disk (OSC), the specific machine disk name, the alarm name and the manufacturer, and the device model. The first performance data collected by the transmission device network management includes the line side optical power information of the optical amplifier disk, the specific port information, the transmission device manufacturer and the device model; for example, the optical power of the collection port.

[0067] The optical line protection network management collects the second alarm information and the second performance data and sends them to the transmission integrated network management. For example, based on the OLP switching alarm, the specific location of the OLP ports at both ends of the relay segment corresponding to the OLP switching is determined. Based on the comparison table of the relay segment and device port location of the OLP system, information such as the equipment room, rack, subframe, and slot can also be obtained. After confirming the port location, it is necessary to collect the optical power performance of the two ports. Figure 3 , Figure 3 This diagram shows the structure of OLP optical power collection. A total of 12 optical power values ​​are collected for each relay segment. The optical power values ​​collected by the OLP ports are defined as follows: RX is the OLP received optical power, R1 is the OLP primary route received optical power, R2 is the OLP backup route received optical power, TX is the OLP transmit optical power, T1 is the OLP primary route optical power, and T2 is the OLP backup route optical power.

[0068] The integrated transmission network management system collects resource data from the long-distance resource management system, including stations, computer rooms, racks, subracks, boards, optical cables, and cable segments. This information is stored in the long-distance resource management system's database tables and is interconnected. This information can be collected using the I3 interface.

[0069] S200: Correlate the first alarm information, the first performance data, the second alarm information, the second performance data, and the network resource data to obtain network structure correlation data.

[0070] Specifically, the integrated transmission network management uses the optical cable segment and system segment of the long-distance resource management system as the standard, organically links the alarm and performance data of the transmission equipment network management, optical protection network management, and long-distance resource management system to obtain network structure correlation data.

[0071] For example, if you receive an alarm indicating that the OLP between wavelength division multiplexing systems A and B is operating on the backup line, you know that the transmission system that switched is a wavelength division multiplexing system, and the station that switched is A and B. Through the transmission system and station, you can obtain the OLP device port and transmission device port from the OLP network management and transmission equipment network management, respectively. Through the correspondence between the transmission system and optical cable, you can obtain the optical cable and optical cable where the switch occurred from the long-distance resource management system. All of this data is collected and correlated. Based on the transmission network management's OTS (Optical Transit Section) port correspondence table, you can obtain information such as the computer room, network element number, subframe, slot, disk name, and port.

[0072] S300: Determine whether the transmission system is interrupted according to the first alarm information and the first performance data.

[0073] Specifically, the transmission integrated network management system determines whether the transmission system is interrupted based on a comprehensive comparison of the first alarm information and the first performance data. For example, if an OSC disk light loss alarm (e.g., OSC_LOS) or an optical line disk light low alarm (e.g., IN_POWER_LOW) is received, the transmission system is determined to be interrupted and the next step is to locate the faulty optical cable segment in the transmission system. Otherwise, the transmission system is determined to be not interrupted and the next step is to determine whether the transmission system has been installed with an OLP device.

[0074] S400: If the transmission system is interrupted, locate the faulty optical cable section of the transmission system according to the first alarm information, the first performance data, and the network structure correlation data.

[0075] Specifically, if the transmission system is interrupted, the fault type is first determined based on the first alarm information and the first performance data, and then the faulty optical cable section of the transmission system is located in combination with the network structure correlation data.

[0076] S500. If the transmission system is not interrupted and the transmission system is installed with an optical protection device, determine whether the main route of the optical protection device is interrupted based on the second alarm information and the second performance data; if the main route of the optical protection device is interrupted, determine the faulty optical cable segment based on the interruption information of the main route and the network structure association data.

[0077] Specifically, if the transmission system is not interrupted, determine whether the transmission system is installed with optical protection equipment. If the transmission system is installed with optical protection equipment, determine whether the main route of the optical protection equipment is interrupted based on the second alarm information and the second performance data; if the main route of the optical protection equipment is interrupted, determine the faulty optical cable section based on the interruption information of the main route and the network structure related data.

[0078] Determine whether the transmission system has OLP installed based on the long-distance resource management system and the OLP network management. If the long-distance resource management system indicates that the transmission system has OLP installed, or if the OLP network management indicates that a transmission system relay segment exists, then the transmission system has OLP installed. Otherwise, the transmission system does not have OLP installed.

[0079] Optionally, the positioning method further includes:

[0080] S501. If the transmission system is not interrupted and no optical protection device is installed in the transmission system, it is determined that the transmission system has no faults;

[0081] S502: Or, if the transmission system is not interrupted, the transmission system is equipped with an optical protection device and the main route of the optical protection device is not interrupted, it is determined that the transmission system has no fault.

[0082] Specifically, transmission system failures include failures on the transmission line and at relay points. If both the transmission line and relay points are fault-free, the transmission system is fault-free. Therefore, if the transmission system is not interrupted and no optical protection equipment is installed, the transmission system is fault-free. If the transmission system is not interrupted, optical protection equipment is installed, and the primary route used by the optical protection equipment is not interrupted, the transmission system is fault-free.

[0083] Optionally, see Figure 4 The first alarm information includes alarm information of the optical monitoring panel, and the first performance data includes line-side optical power information of the optical line panel. Locating the faulty optical cable section of the transmission system based on the first alarm information, the first performance data, and the network structure-related data specifically includes:

[0084] S410: If the optical monitoring panel alarm information includes a received light loss alarm, and the line-side optical power information includes an optical line panel received light power lower than a first preset value, locate the optical relay segment corresponding to the received light loss alarm as a faulty optical cable segment based on the network structure association data;

[0085] S420. If the optical monitoring disk alarm information does not include a received light loss alarm, and the line-side optical power information includes an optical line disk received light power lower than a first preset value, the optical relay segment corresponding to the optical line disk received light power lower than the first preset value is located as a faulty optical cable segment according to the network structure associated data.

[0086] Specifically, if the optical circuit board's received optical power, as included in the line-side optical power information, falls below a first preset value, an optical circuit board low received optical power alarm is generated. The fault type is first determined based on the received optical power loss alarm and the optical circuit board low received optical power alarm. The fault location is then determined based on the fault type and network structure correlation data.

[0087] For example, if the transmission system receives both an OSC panel loss of received light alarm (e.g., OSC_LOS) and an optical line panel low received light alarm (e.g., IN_POWER_LOW), the faulty segment is the OTS segment of the OSC panel loss of received light alarm. If the transmission system does not receive an OSC panel loss of received light alarm (e.g., OSC_LOS) but receives an optical line panel low received light alarm (e.g., IN_POWER_LOW), the faulty segment is the OTS segment of the optical line panel low received light alarm.

[0088] It should be noted that the first preset value is determined according to actual application and is not specifically limited in this embodiment. For example, the first preset value is set to an alarm threshold value.

[0089] Optionally, see Figure 5 The second performance data includes power data of the main routing light emitting port and power data of the main routing light receiving port. Determining whether the main routing of the optical protection device is interrupted based on the second alarm information and the second performance data specifically includes:

[0090] S510, determining a primary routing light emitting port and a primary routing light receiving port according to the second alarm information;

[0091] S520: Determine a primary routing line loss reference value and a primary routing line loss current value based on the power data of the primary routing light emitting port and the power data of the primary routing light receiving port;

[0092] S530, calculating the difference between the current value of the primary routing line loss and the primary routing line loss reference value;

[0093] S540: If the difference is greater than a second preset value, determine that the primary route is disconnected;

[0094] S550: If the difference is less than or equal to the second preset value, determine that the primary route is not interrupted.

[0095] First, the main routing light-emitting port and the main routing light-receiving port are extracted from the second alarm information, and then the power data of the main routing light-emitting port and the power data of the main routing light-receiving port are collected. Then, the main routing line loss baseline value and the main routing line loss current value are calculated based on the power data of the main routing light-emitting port and the power data of the main routing light-receiving port. Then, the main routing interruption is determined based on the relationship between the difference between the current value of the main routing line loss and the main routing line loss baseline value and the second preset value.

[0096] It should be noted that the second preset value is determined according to actual application and is not specifically limited in this embodiment. For example, the second preset value is set to 5dB.

[0097] The calculation method for the primary route line loss baseline value and the primary route line loss current value is as follows.

[0098] T1: The primary emitting port of the OLP router; R1: The primary receiving port of the OLP router; Current Value: The real-time optical power performance data of T1 or R1 collected during the same time period as the optical cable fault location; Baseline Value: The historical performance data of T1 or R1 optical power collected when the transmission system and optical protection equipment are operating normally; Opposite End: The T1 and R1 ports on the same optical fiber line within the same OLP relay segment.

[0099] The primary routing line loss reference value = T1 reference value - the peer end's R1 reference value;

[0100] The current value of the main routing line attenuation = the current value of T1 - the current value of R1 at the other end.

[0101] T1: The primary optical transmission port of the OLP; R1: The primary optical reception port of the OLP; Current Value: The real-time optical power performance data of T1 or R1 collected during the same time period as the optical cable fault location; Baseline Value: The historical optical power performance data of T1 or R1 collected when the transmission system and optical protection equipment are operating normally; Opposite End: The T1 and R1 ports on the same optical fiber line within the same OLP relay segment.

[0102] Optionally, determining the faulty optical cable segment according to the interruption information of the primary route and the network structure association data specifically includes:

[0103] S560: Locate the switching relay segment of the interrupted primary route as the faulty optical cable segment based on the network structure association data.

[0104] Specifically, the interruption location is first determined according to the interruption information of the primary route, and then the switching relay section of the primary route is located as the faulty optical cable section according to the interruption location and network structure correlation data.

[0105] Optionally, see Figure 6 , the above positioning method further includes:

[0106] S600, counting the number of transmission systems that are interrupted within a preset time period;

[0107] S700: If the number is greater than 1, determine whether the faulty optical cable segments of each transmission system overlap; if so, merge the faulty optical cable segments of the overlapping transmission systems.

[0108] It should be noted that the preset time period is determined according to actual application and is not specifically limited in this embodiment. For example, the preset time period is set to 3 minutes.

[0109] Within a preset time period, the number of faulty optical cable segments in the transmission system is counted and located to determine whether a single transmission system fault exists. Because NE alarm reporting and merging take time, and because support systems like the integrated alarm system may experience delays in dispatching alarms, a time threshold is set. For example, the preset time period can be set to 3 minutes.

[0110] In a specific embodiment, if the number of transmission system faulty optical cable segments located within 3 minutes is greater than 1, it is determined that there are line faults with multiple transmission systems interrupted, and then it is determined whether the locations of the faulty optical cable segments with multiple transmission systems interrupted overlap. If the locations of the faulty optical cable segments of each transmission system do not overlap, it is determined that multiple optical cable segments have failed, and the locations of the optical cable segments with multiple line faults are determined; if the number of transmission system faulty optical cable segments located within 3 minutes is 1, it is determined that there is only a line fault with a single transmission system interrupted, and the location of the optical cable segment with a single line fault is determined.

[0111] See Figure 7 , the following describes the optical cable fault location process in this application using a specific embodiment.

[0112] S1: The transmission integrated network management collects alarm data and performance data from the transmission equipment network management.

[0113] S2: The transmission integrated network management collects alarm data and performance data from the optical protection network management.

[0114] S3: The transmission integrated network management collects resource data from the long-distance resource management system.

[0115] S4: Realize data association among transmission equipment network management, optical protection network management, and long-distance resource management system.

[0116] S5: Determine whether there is a transmission system interruption based on the transmission equipment alarm and performance; if the transmission system is interrupted, the next step is to proceed to step S8 (locating the faulty optical cable section of the transmission system); otherwise, it is determined that there is no transmission system interruption, and the next step is to proceed to step S6 (whether the transmission system has an OLP device installed).

[0117] S6: Determine whether the transmission system has installed OLP equipment based on data from the long-distance resource management system and the OLP network management system. If the transmission system has installed OLP equipment, the process proceeds to step S7 (determines whether the primary OLP route has been interrupted). Otherwise, the process determines that the transmission system has not installed OLP equipment, and the process proceeds to step S14 (no optical cable failure has occurred in the transmission system).

[0118] S7: Calculate the line loss of the primary OLP route and determine whether the primary OLP route is interrupted based on the line loss. If the primary OLP route is interrupted, the process proceeds to step S8 (locating the faulty optical cable segment in the transmission system). Otherwise, the process determines that the primary OLP route is not interrupted and proceeds to step S14 (no optical cable fault in the transmission system).

[0119] S8: Locate the faulty optical cable section of the transmission system based on the alarms and performance received by the transmission system and the alarms and performance received by the optical protection network management: If the transmission system receives both the OSC disk light loss alarm (e.g., OSC_LOS) and the optical line disk light low alarm (e.g., IN_POWER_LOW), the faulty section is the OTS section of the OSC disk light loss alarm; if the transmission system does not receive the OSC disk light loss alarm (e.g., OSC_LOS) but receives the optical line disk light low alarm (e.g., IN_POWER_LOW), the faulty section is the OTS section of the optical line disk light low alarm; if the transmission system is not interrupted but the OLP primary route is interrupted, the faulty section is the OLP switching relay section.

[0120] S9: Determine whether there is only a single transmission system line fault within 3 minutes: If the number of transmission system faulty optical cable segments (S8) located within 3 minutes is greater than 1, it is determined that there are line faults with multiple transmission systems interrupted, and the process goes to step S10 (whether the locations of the faulty optical cable segments with multiple transmission systems interrupted are the same); if the number of transmission system faulty optical cable segments (S8) located within 3 minutes is 1, it is determined that there is only a single transmission system line fault interrupted, and the process goes to step S13 (determine the location of the optical cable segment with a single line fault).

[0121] S10: Whether there is overlap in the positioning of the faulty optical cable segments of multiple transmission system interruptions: If multiple transmission systems are interrupted within 3 minutes, determine whether there is overlap in the positioning of the faulty optical cable segments of each transmission system; if there is no overlap in the positioning of the faulty optical cable segments of each transmission system, it is determined that multiple optical cable segments have failed, and the process goes to step S11 (determine the positioning of the optical cable segments of multiple line faults); if there is overlap in the positioning of the faulty optical cable segments of each transmission system, it is determined that only one optical cable segment has failed, and the process goes to step S12 (treat the overlapping optical cable segments as the faulty optical cable segments).

[0122] S11: Determine the locations of optical cable segments of multiple line faults: If the locations of the faulty optical cable segments of each transmission system do not overlap, it is determined that multiple optical cable faults occur simultaneously, and the locations of the optical cable segments of the multiple line faults are output respectively.

[0123] S12: Taking the overlapping optical cable segments as the obstructed optical cable segments: If the faulty optical cable segments of each transmission system overlap and it is determined that only one optical cable segment has failed, then the process goes to step S13 (locating the optical cable segment of a single line obstruction).

[0124] S13: Locating the optical cable segment of a single line fault: If only a single transmission system is interrupted (S9), the faulty segment of the transmission system is used as the optical cable segment of the single line fault; if multiple transmission systems are interrupted and the faulty segments overlap (S12), the overlapping optical cable segments are used as the optical cable segment of the single line fault.

[0125] S14: No optical cable fault occurs in the transmission system: If the transmission system is not interrupted and the OLP device is not installed (S6), it is determined that no optical cable fault occurs in the transmission system; if the transmission system is not interrupted and the OLP device is installed, and the attenuation of the OLP main routing line is normal, it is determined that no optical cable fault occurs in the transmission system.

[0126] In a specific embodiment, see Figure 8 , Figure 8This figure shows the display effect after fault location. The transmission system includes multiple relay points such as A, B, C, D, E, F, M, N, and L. According to the above-mentioned optical cable fault location method, it is determined that the BN segment, BC segment, and CD segment optical cables have faults. The faulty optical cable segment is marked in bold, and the entire system network is output for easy viewing.

[0127] Implementation of the embodiments of the present invention provides the following advantageous effects: In this embodiment, first, multiple alarm information and performance data are obtained from the transmission equipment network management, the optical line protection network management, and the long-distance resource management system, respectively. The multiple alarm information and performance data are correlated to obtain network structure correlation data, and judgment data required for subsequent fault location is collected. Next, whether the transmission system is interrupted is determined based on the alarm information and performance data. If the transmission system is interrupted, the faulty optical cable segment of the transmission system is located based on the first alarm information, the first performance data, and the network structure correlation data, thereby automatically locating the optical cable fault based on the first alarm and first performance of the optical transmission equipment. Next, if the transmission system is not interrupted and the transmission system is equipped with an optical protection device, whether the primary route of the optical protection device is interrupted is determined based on the second alarm information and the second performance data. If the primary route of the optical protection device is interrupted, the faulty optical cable segment is determined based on the interruption information of the primary route and the network structure correlation data, thereby automatically locating the optical cable fault based on the second alarm and second performance of the optical line protection device. Furthermore, this embodiment also combines the alarms and performance of the optical transmission equipment and the optical line protection device to automatically locate the optical cable fault, thereby improving the efficiency and accuracy of optical cable fault location.

[0136] if the optical monitoring disc alarm information does not contain the light receiving loss alarm and the optical line disc light receiving power contained in the line side optical power information is lower than the first preset value, the optical relay section corresponding to the optical line disc light receiving power lower than the first preset value is located as the fault optical cable section according to the network structure correlation data.
