[0002] As a key device for building a communication network, the operational reliability and safety of the fiber optic transceiver are crucial to the reliable operation of the entire communication network. Therefore, how to achieve automatic detection and diagnosis of fiber optic transceiver faults has become a technical problem that needs to be solved urgently.

[0003] In order to solve the above technical problems, the invention patent CN201810525156.X "A Fault Detection System and Detection Method for Fiber Optic Transceiver" analyzes the voltage and current values ​​of each interface to determine whether each interface has a fault, thereby achieving accurate detection of the fault state of the fiber optic transceiver. However, there are the following technical problems:

[0004] The existing technical solutions ignore the determination of differentiated fault detection sequences according to the differences between different fiber optic transceivers. Specifically, a complete communication network system often includes multiple fiber optic transceivers. Since the node positions of different fiber optic transceivers are different and the number of ports used is also different to a certain extent, there are certain differences in the failure probability and the importance of the node. If the above factors cannot be considered to determine the differentiated fault detection sequence, it is impossible to efficiently screen out faulty fiber optic transceivers.

[0005] In view of the above technical problems, the present invention provides a method and system for detecting faults of an optical fiber transceiver. Summary of the invention

[0006] To achieve the purpose of the present invention, the present invention adopts the following technical solutions:

[0007] According to one aspect of the present invention, a method for detecting faults of an optical fiber transceiver is provided.

[0008] A method for detecting a fault in an optical fiber transceiver, characterized by comprising:

If so, the fault detection order of the optical fiber transceiver is determined by the position evaluation value. If not, proceed to the next step;

[0011] S3 determines the transmission distances of the optical signals received by the different ports of the optical transceiver according to the transmission paths of the optical signals received by the different ports, determines the attenuation problem evaluation amounts of the different ports in combination with the historical attenuation conditions, and divides the types of the ports into concerned ports and normal ports according to the attenuation problem evaluation amounts;

[0017] A further technical solution is that the attenuation of the optical signal of the terminal node is determined according to the deviation between the signal strength of the optical signal of the terminal node and the standard signal strength of the terminal node.

[0018] A further technical solution is that the value range of the fault state value of the communication network is between 0 and 1, wherein the larger the fault state value of the communication network is, the more serious the fault state of the communication network is.

[0019] A further technical solution is that the fault impact range of the fiber optic transceiver is determined according to the communication network connected to the signal output end of the fiber optic transceiver, and specifically determined according to the number of fiber optic transceivers and the number of terminal nodes in the communication network connected to the signal output end of the fiber optic transceiver.

[0022] A further technical solution is to determine whether the optical fiber transceiver belongs to a core transceiver based on the position evaluation value, specifically including:

[0023] When the position evaluation value of the optical fiber transceiver is greater than a preset value, the optical fiber transceiver is determined to be a core transceiver, wherein the preset value is determined according to the number of optical fiber transceivers in the communication network.

[0024] A further technical solution is to classify the types of ports into concerned ports and normal ports according to the attenuation problem evaluation amount, specifically including:

[0025] When the attenuation problem evaluation amount of the port is within the preset attenuation limit range, the type of the port is determined to be a normal port; when the attenuation problem evaluation amount of the port is not within the preset attenuation limit range, the type of the port is determined to be a concerned port.

[0038] In order to enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below in conjunction with the drawings in the embodiments of this specification. Obviously, the described embodiments are only part of the embodiments of this specification, not all of the embodiments. Based on the embodiments of this specification, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this specification.

[0039] The applicant has found that in a large-scale communication network, once a network failure occurs in a fiber optic transceiver, due to the large number of fiber optic transceivers in the communication network, the port states of different fiber optic transceivers also differ to a certain extent. At the same time, different fiber optic transceivers are located in different positions in the communication network. Therefore, if the above factors are not comprehensively considered to determine the fault detection order, the efficiency of fault detection cannot be improved.

[0040] Example 1

[0041] To solve the above problems, according to one aspect of the present invention, Figure 1 As shown, a method for detecting a fault of an optical fiber transceiver is provided, which is characterized by comprising:

[0042] S1 determines the terminal nodes of the communication network to be detected and analyzed based on the terminal users of the communication network to be detected and analyzed, and determines the fault state value of the communication network through the attenuation of the optical signals of different terminal nodes of the communication network to be detected and analyzed, and when the fault state value does not meet the requirements, proceeds to the next step;

[0043] It should be further explained that the attenuation of the optical signal of the terminal node is determined according to the deviation between the signal strength of the optical signal of the terminal node and the standard signal strength of the terminal node.

[0044] Specifically, the method for determining the fault status value of the communication network in step S1 is as follows:

[0045] S11 determines the attenuation of the optical signal of the terminal node of the communication network to be detected and analyzed based on the attenuation of the optical signal of the terminal node, and determines whether there is a terminal node with an attenuation greater than a preset attenuation. If so, proceed to step S13, if not, proceed to step S12;

[0046] S12 determines the attenuation threshold of the terminal node according to the type of the terminal node, and determines whether there is a terminal node with an attenuation greater than the attenuation threshold. If so, proceed to step S13. If not, determine the fault state value of the communication network according to the average value of the attenuation of the optical signal of different terminal nodes.

[0047] S13: taking the terminal nodes whose attenuation is greater than the preset attenuation as attenuation terminal nodes, and determining the severe attenuation assessment amount of the communication network based on the number of the attenuation terminal nodes, the ratio of the terminal nodes, and the attenuation of the optical signals at the attenuation terminal nodes;

[0048] S14 regards the terminal nodes whose attenuation is greater than the attenuation threshold as problem terminal nodes, and determines the attenuation problem assessment amount of the problem terminal nodes based on the number of the problem terminal nodes, the average value and the maximum value of the deviation between the attenuation and the attenuation threshold, and determines the fault status value of the communication network through the attenuation problem assessment amount and the severe attenuation assessment amount.

[0049] It can be understood that the value range of the fault state value of the communication network is between 0 and 1, wherein the larger the fault state value of the communication network is, the more serious the fault state of the communication network is.

[0050] In this embodiment, the fault status value of the communication network is determined by the attenuation of optical signals of different terminal nodes of the communication network to be detected and analyzed, thereby realizing the judgment of the fault status of the communication network based on the actual signal attenuation of users, thereby also realizing the accurate determination of the timing of fault detection of the optical fiber transceiver from the perspective of the entire user.

If so, the fault detection order of the optical fiber transceiver is determined by the position evaluation value. If not, proceed to the next step;

[0052] Specifically, the fault impact range of the fiber optic transceiver is determined according to the communication network to which the signal output end of the fiber optic transceiver is connected, and specifically determined according to the number of fiber optic transceivers and the number of terminal nodes in the communication network to which the signal output end of the fiber optic transceiver is connected.

[0053] Specifically, the method for determining the position evaluation value in step S2 is:

[0054] The number of fiber optic transceivers and the number of terminal nodes within the fault impact range of the fiber optic transceiver are determined by the fault impact range of the fiber optic transceiver, and the position evaluation value of the fiber optic transceiver is determined based on the number of fiber optic transceivers and the number of terminal nodes.

[0055] In one possible embodiment, determining whether the optical fiber transceiver belongs to a core transceiver based on the position evaluation value in step S2 specifically includes:

[0056] When the position evaluation value of the optical fiber transceiver is greater than a preset value, the optical fiber transceiver is determined to be a core transceiver, wherein the preset value is determined according to the number of optical fiber transceivers in the communication network.

[0057] In this embodiment, the fault impact range and position evaluation value of the fiber optic transceiver are determined by using different positions of the fiber optic transceiver in the communication network, thereby further taking into account the differences in the importance of the positions due to the differences in the positions of the photovoltaic transceivers, ensuring that the fiber optic transceivers with a larger impact range can be detected in a timely manner, thereby further improving the efficiency of the detection process.

[0058] S3 determines the transmission distances of the optical signals received by the different ports of the optical transceiver according to the transmission paths of the optical signals received by the different ports, determines the attenuation problem evaluation amounts of the different ports in combination with the historical attenuation conditions, and divides the types of the ports into concerned ports and normal ports according to the attenuation problem evaluation amounts;

[0059] Specifically, the method for determining the attenuation problem evaluation amount of the port in step S3 is as follows:

[0061] S22 determines whether the attenuation of the port does not meet the required attenuation times according to the historical attenuation of the optical signal of the port. If yes, proceed to step S24; if not, proceed to step S23;

[0062] S23 determines the historical attenuation amount of the optical signal of the port according to the historical attenuation of the optical signal of the port, and determines whether the historical attenuation of the optical signal of the port is serious based on the average value of the historical attenuation of the optical signal of the port, if so, proceeds to step S24, if not, determines the attenuation problem assessment amount of the port according to the average value of the historical attenuation of the optical signal of the port;

[0063] S24 obtains the problem attenuation times of the port and the maximum value of the historical attenuation amount of the problem attenuation times, and determines the historical problem evaluation amount of the port in combination with the maximum value of the problem attenuation times of the port in unit time;

[0064] S25 takes the average value of the historical attenuation of the optical signal of the port as the attenuation average value, and determines the attenuation problem assessment amount of the port according to the number of times the historical attenuation of the optical signal of the port is greater than the attenuation average value, the optical signal attenuation probability of the port, and the historical problem assessment amount of the port.

[0065] It can be understood that the types of ports are divided into concerned ports and normal ports according to the attenuation problem evaluation amount, including:

[0066] When the attenuation problem evaluation amount of the port is within the preset attenuation limit range, the type of the port is determined to be a normal port; when the attenuation problem evaluation amount of the port is not within the preset attenuation limit range, the type of the port is determined to be a concerned port.

[0069] When any one of the transmission distance of the optical signal of the port and the number of optical fiber transceivers on the transmission path cannot meet the requirements:

[0070] Determine the optical signal attenuation probability of the port according to the transmission distance of the optical signal of the port, the number of optical fiber transceivers on the transmission path, and the transmission distance between different optical fiber transceivers on the transmission path, and use the optical signal attenuation probability of the port as an attenuation problem evaluation amount;

[0071] When the transmission distance of the optical signal of the port and the number of optical fiber transceivers on the transmission path meet the requirements:

[0072] Judging from the historical attenuation of the optical signal of the port, whether the port has the problem that the attenuation does not meet the requirement, attenuation times:

[0073] Determine the attenuation problem assessment amount of the port by using the average value of the historical attenuation amount of the optical signal of the port;

[0074] Judging from the historical attenuation of the optical signal of the port that the attenuation of the port does not meet the requirement, attenuation times:

[0075] The number of problematic attenuation times of the port and the maximum value of the historical attenuation of the problematic attenuation times are obtained, and the historical problem evaluation amount of the port is determined in combination with the maximum value of the problematic attenuation times of the port in unit time, and the average value of the historical attenuation of the optical signal of the port is taken as the attenuation average value, and the attenuation problem evaluation amount of the port is determined by the number of times the historical attenuation of the optical signal of the port is greater than the attenuation average value, the optical signal attenuation probability of the port, and the historical problem evaluation amount of the port.

[0077] Specifically, Figure 2 As shown, the method for determining the port failure probability of the optical fiber transceiver in the above step S4 is:

[0078] S31 determines the concerned ports of the optical fiber transceiver by using the port type of the optical fiber transceiver, and determines whether the number of concerned ports of the optical fiber transceiver is greater than the preset port number, if so, proceeds to step S34, if not, proceeds to the next step;

[0079] S32 determines whether there is a port whose attenuation problem evaluation value is greater than a preset problem evaluation value according to the attenuation problem evaluation value of the port of the optical fiber transceiver, and if so, proceeds to the next step; if not, determines the port failure probability of the optical fiber transceiver by the maximum value of the attenuation problem evaluation value of the port of the optical fiber transceiver;

The problem probability of the fiber optic transceiver is determined according to the comprehensive attenuation value of the concerned port of the fiber optic transceiver and the basic attenuation value of the fiber optic transceiver.

[0091] In this embodiment, the fault detection priority value of the fiber optic transceiver is obtained by utilizing the port failure probability, position evaluation value and number of ports of the fiber optic transceiver. This not only takes into account the differences in the port failure probabilities of different fiber optic transceivers, but also takes into account the differences in detection priority situations caused by the number of ports and the importance of the positions, thereby further improving the efficiency and reliability of the detection process.
