Description

Technical Field

[0001] This application relates to the technical field of optical cable testing, and in particular to a testing method, system, device and storage medium for active optical cables. Background Technology

[0002] 400G cable testing is a common task in data centers and large-scale networks. As data transmission rates continue to increase, the testing requirements for cables are also becoming more stringent.

[0003] Many manufacturers have launched testing solutions for 400G cables, offering comprehensive testing capabilities including bit error rate (BER) testing, eye diagram testing, and jitter testing. Due to the extremely high data transmission rate of 400G cables, the requirements for testing accuracy are also very high, making testing equipment expensive. Therefore, reducing the cost of cable testing is a pressing technical problem that needs to be solved. Summary of the Invention

[0004] This application provides a testing method, system, device, and storage medium for active optical cables. It allows for testing using existing terminal equipment controlled by a computer program, eliminating the need to develop new testing equipment and thus reducing testing costs.

[0005] The first aspect of this application provides a testing method for active optical cables: a testing method for active optical cables, applied to the cable under test, the method comprising:

[0006] Obtain the test command for the cable under test;

[0007] According to the test command of the cable under test, determine whether there is a connection abnormality. The connection abnormality is an abnormal state such as no cable is inserted into the target port, no normal connection, and / or inconsistent speed.

[0008] If there is no connection anomaly, then clear the interference data. The interference data consists of residual information generated after the most recent batch of tested cables were disconnected and the access information of the cable to be tested.

[0009] Obtain the port information of the target port, the port information including bit error rate and signal quality;

[0010] Based on the bit error rate and signal quality, determine whether there is a signal anomaly;

[0011] If no signal abnormality is found, log information is obtained after a preset control time, and the target port is judged to have packet loss, delay abnormality and / or disconnection based on the log information.

[0012] If there is no packet loss, no delay anomaly, and / or no connection failure, then the cable under test is determined to have completed the cable test.

[0013] By adopting the above technical solution, after the program is imported into the testing equipment, the equipment first performs a preliminary test on the cable under test at the access port, that is, it checks whether the cable is connected, whether the connection is secure, and whether the port detection rate matches the theoretical rate. After the preliminary test is passed, interference data is cleared to avoid residual information from the previous batch of tested cables and unstable information when the cable under test is newly connected, thereby improving information reliability. Then, the bit error rate and signal quality of the port are obtained to determine whether there are any anomalies. After confirming that there are no anomalies, the target port is controlled to simulate a scenario of large-scale data attack, and is tested again after the corresponding control time to determine whether there are any packet loss, delay anomalies, and / or disconnection. If none are found, the cable under test is determined to have passed the test. Thus, the computer program performs the test on the cable under test, avoiding the use of specific testing instruments and reducing testing costs.

[0014] Optionally, the method further includes:

[0015] If the connection error exists, a connection error message will be sent.

[0016] Repair the connection error according to the connection error message until the error state is resolved.

[0017] By adopting the above technical solution, if a connection failure or speed inconsistency is found between the cable under test and the target port during the initial inspection, a corresponding cable abnormality warning message is sent and the cable is returned for repair. After repair, the cable is tested again until no abnormalities are found before proceeding to the next inspection step. This process effectively filters out a batch of cables that may have quality problems during the initial inspection, allowing for timely repair.

[0018] Optionally, the method further includes:

[0019] If the cable under test is abnormal, a signal abnormality prompt message will be sent.

[0020] Perform fault repair based on the signal anomaly message until the signal anomaly is resolved.

[0021] By adopting the above technical solution, after the initial test is passed, the interference log information is cleared and the bit error rate and signal quality of the target port are obtained to determine whether there is a quality problem with the cable under test. If there is, an abnormality prompt message is sent accordingly. After the corresponding repair is carried out according to the prompt message, the test is repeated until the abnormality is resolved before proceeding to the next test step. Thus, a second test is performed after the initial test, and a batch of cables under test with excessively high bit error rates and / or poor signal quality are screened out and returned for repair.

[0022] Optionally, the method further includes:

[0023] If the packet loss, latency anomaly, and / or connection failure occurs, a reliability anomaly warning message will be sent.

[0024] Perform fault repair based on the reliability anomaly message until there are no more packet loss, latency anomalies, or connection drops.

[0025] By adopting the above technical solution, the target port is controlled to simulate a scenario where a large amount of data is sent through the port of the cable under test. After simulating the preset control time, the log information is read to determine whether there is packet loss, delay anomaly and / or disconnection, thereby detecting the reliability of the cable under test. If there is, an anomaly prompt is sent accordingly, and the cable is returned for maintenance based on the anomaly prompt to ensure the reliability of the cable under test.

[0026] Optionally, before the step of obtaining the port information of the target port, wherein the port information includes the bit error rate and signal quality of the cable under test, the method further includes:

[0027] Obtain the serial number of the cable under test;

[0028] The serial number of the cable under test is associated with the cable under test one by one for the purpose of anomaly tracing in subsequent testing.

[0029] By adopting the above technical solution, the serial number of the cable under test is associated with the cable under test one by one, and the serial number of the cable under test is returned to ensure that the test data corresponds one by one with the cable under test, and subsequent anomalies can be traced.

[0030] Optionally, the step of obtaining log information after a preset control time if the cable under test does not have any abnormalities includes:

[0031] The target port is subjected to pressure to control it into port storm mode, in which a large amount of fake traffic is generated to simulate a network attack scenario.

[0032] After entering the port storm mode, the log information is obtained after the control period.

[0033] By adopting the above technical solution, the target port is pressured to enter port storm mode. In port storm mode, the target port receives a large amount of data and simulates a large amount of data entering. After the control period, log information is read to determine the performance and defense capabilities of the target port.

[0034] Optionally, before the step of obtaining the test command for the cable under test, the method includes:

[0035] Get test management instructions;

[0036] According to the test management instructions, the test terminal is connected to the test system to perform the cable test through the test terminal.

[0037] By adopting the above technical solution, the corresponding management permissions are obtained and corresponding test management instructions are sent based on the management permissions, so as to connect the relevant terminal devices under management. Then, according to the test management instructions, the terminal under test is connected to the manager so that the subsequent test steps can be executed through the manager.

[0038] A second aspect of this application provides a testing system for active optical cables, comprising:

[0039] The test command acquisition module is used to acquire test commands for the cable under test.

[0040] The first anomaly detection module is used to determine whether there is a connection anomaly based on the test command of the cable under test. The connection anomaly is an abnormal state such as no cable is inserted into the target port, no normal connection, and / or inconsistent speed.

[0041] The interference data clearing module is used to clear interference data if there is no connection abnormality. The interference data includes residual information generated after the most recent batch of tested cables were disconnected and access information of the cable to be tested.

[0042] The port information acquisition module is used to acquire the port information of the target port, including bit error rate and signal quality.

[0043] The second anomaly detection module is used to determine whether there is a signal anomaly based on the bit error rate and signal quality.

[0044] The third anomaly detection module is used to obtain log information after a preset control time if there is no signal anomaly, and to determine whether there is packet loss, delay anomaly and / or disconnection on the target port based on the log information.

[0045] The test completion determination module is used to determine that the cable under test has completed the cable test if there is no packet loss, delay abnormality and / or disconnection.

[0046] A third aspect of this application provides an apparatus including a memory and a processor, the memory storing a computer program capable of executing the above-described test method for active optical cables.

[0047] The fourth aspect of this application provides a storage medium storing a computer program capable of executing the above-described test method for active optical cables.

[0048] In summary, this application has at least one of the following beneficial effects:

[0049] 1. After importing the program into the testing equipment, the equipment first performs a preliminary test on the cable under test at the access port, that is, it checks whether the cable is connected, whether the connection is secure, and whether the port detection rate matches the theoretical rate. After the preliminary test is passed, interference data is cleared to avoid residual information from the previous batch of tested cables and unstable information when the cable under test is newly connected, thereby improving information reliability. Then, the bit error rate and signal quality of the port are obtained to determine if there are any anomalies. After confirming that there are no anomalies, the target port is controlled to simulate a scenario of large-scale data attack, and is tested again after the corresponding control time to determine if there are any packet loss, delay anomalies, and / or disconnection. If none are found, the cable under test is determined to have passed the test. Thus, the cable under test is tested by the computer program, avoiding the use of specific testing instruments and reducing testing costs.

[0050] 2. After the initial test passes, the interference log information is cleared and the bit error rate and signal quality of the target port are obtained to determine whether there is a quality problem with the cable under test. If so, an abnormality prompt message is sent accordingly. Repairs are carried out according to the prompt message, and the test is repeated until the abnormality is resolved before proceeding to the next testing step. This secondary test after the initial test filters out a batch of cables under test with excessively high bit error rates and / or poor signal quality and returns them for repair. Clearing the log information can avoid interference from residual information of the most recently tested cables and inaccurate information caused by the instability of newly connected cables under test, thereby improving the reliability of the log information.

[0051] 3. Apply pressure to the target port to put it into port storm mode. In port storm mode, the target port receives a large amount of data and simulates a large influx of data. After the control period, read the log information to determine the performance and defense capabilities of the target port. If the preset control period is simulated, read the log information to determine whether there is packet loss, delay anomaly and / or disconnection, thereby detecting the reliability of the cable under test. If any issues are found, send an anomaly prompt and return to maintenance based on the anomaly prompt to ensure the reliability of the cable under test. Attached Figure Description

[0061] To make the purpose, technical solution and advantages of this application clearer, the testing method of the active optical cable of this application will be described below from the perspective of the testing device for the active optical cable. The testing device for the active optical cable can be an electronic device, such as a mobile phone terminal, a computer terminal and other devices.

[0062] The present application will be further described in detail below with reference to the accompanying drawings.

[0063] Reference Figure 1 , Figure 1 This is a flowchart illustrating the testing method for active optical cables provided in this application embodiment, applied to the cable under test and the target port for connecting to the cable under test. The following describes the method in conjunction with... Figure 1 The steps involved in the testing method are explained in detail:

[0064] In step S1, the test command for the cable under test is obtained.

[0065] Specifically, the test command for the cable under test is sent by the relevant test personnel (hereinafter referred to as the target user) through the relevant control equipment (hereinafter referred to as the control equipment). The sending method includes, but is not limited to, knobs, buttons, touch controls, etc. Before sending the test command for the cable under test, the target user also needs to obtain the corresponding test permission, which is explained in detail below:

[0066] Get test management instructions;

[0067] According to the test management instructions, the test terminal is connected to the test system to perform the cable test through the test terminal.

[0068] Specifically, in this embodiment, the target user first needs to control the server to enter root mode. Server root mode refers to the mode in which one logs in or executes commands as a superuser in the server operating system. Enabling root mode grants administrative privileges, which are then used to open the SM management function. SM management function typically refers to Session Management, an important component of network applications. Through the SM management function, the terminal under test (DUT), including the target port, is connected to the manager. The manager is a terminal device with the function of managing the DUT, and can be a control device used by the target user to control the execution of test steps and receive test data. It is worth noting that testing active optical cables typically includes testing both the cable itself and the connection ports; that is, in this test, both the performance of the cable under test and the performance of the ports to which the cable is connected are tested.

[0069] In step S2, according to the test command of the cable under test, it is determined whether there is a connection abnormality. The connection abnormality is an abnormal state such as no cable is inserted into the target port, no normal connection, and / or inconsistent speed.

[0070] Specifically, a preliminary test is performed on the connection status of the cable under test connected to the target port. In this embodiment, four speeds are supported: 56G, 100G, 200G, and 400G. The test instructions include corresponding script instructions. That is, the corresponding test script is selected according to the different speeds required for the test. Then, the corresponding standard information for comparison and judgment is extracted according to the selected test script, so as to determine whether the target port is connected to the cable, whether the cable under test is successfully connected to the target port, and whether the comparison result of the measured speed is within a certain range, thereby determining whether there is an abnormality in the connection.

[0071] More specifically, in the event of a connection error, the target port or the cable under test needs to be returned for repair. The details are as follows:

[0072] If the connection error exists, a connection error message will be sent.

[0073] Repair the connection error according to the connection error message until the error state is resolved.

[0074] Specifically, connection error messages can be issued according to the type of connection error, allowing for manual intervention or automatic correction by the device for maintenance. After maintenance, the connection status is retested until the connection status is correct before proceeding to the next testing step.

[0075] In step S3, if there is no connection abnormality, the interference data is cleared. The interference data consists of residual information generated after the most recent batch of tested cables were disconnected and the access information of the cable to be tested.

[0076] Specifically, clearing interference data means clearing the log information. The cleared log information includes, but is not limited to, log information left over from the testing of historical test cables, as well as log information related to instability that may occur when the cable under test is first started after the target port is connected to the cable under test. After clearing, the test is started to eliminate interference information and improve test reliability.

[0077] In step S4, the port information of the target port is obtained, including the bit error rate and signal quality;

[0078] In step S5, based on the bit error rate and signal quality, it is determined whether there is a signal abnormality.

[0079] Specifically, after clearing log information that may cause interference, the port information of the target port is read, including the bit error rate and signal quality. Based on the returned information of bit error rate and signal quality, standard information from the corresponding script is extracted and compared to determine whether the signal quality and bit error rate of the target port meet the preset standards. The preset standards can be set by the target user through the manager. If there are signal abnormalities, the corresponding prompt information is sent to return for maintenance. The details are explained below:

[0080] If the cable under test is abnormal, a signal abnormality prompt message will be sent.

[0081] Perform fault repair based on the signal anomaly message until the signal anomaly is resolved.

[0082] Specifically, the equipment is manually calibrated or controlled to perform repairs. After repairs, the connection status is retested until the connection status is correct before proceeding to the next testing step.

[0083] Furthermore, to ensure that the returned information corresponds correctly, this embodiment also provides an identification method, which is described in detail below:

[0084] Obtain the serial number of the cable under test;

[0085] The serial number of the cable under test is associated with the cable under test one by one for the purpose of anomaly tracing in subsequent testing.

[0086] Specifically, when the relevant testing equipment detects information about the cable under test and returns it to the manager, it identifies and matches the data, that is, returns the serial number of the cable under test, to ensure that the test data corresponds one-to-one with the cable under test, and subsequent anomalies can be traced.

[0087] In step S6, if there is no signal abnormality, log information is obtained after a preset control time, and the target port is judged to have packet loss, delay abnormality and / or disconnection based on the log information.

[0088] Specifically, if no signal abnormalities are found, it can be understood that no abnormalities have been detected in the target port and the cable under test at the current state. However, for the purpose of testing the performance of the target port and the cable under test, port management still needs to be enabled. In this embodiment, port management is implemented in port storm mode, which will be explained in detail below:

[0089] The target port is subjected to pressure to control it into port storm mode, in which a large amount of fake traffic is generated to simulate a network attack scenario.

[0090] After entering the port storm mode, the log information is obtained after the control period.

[0091] Specifically, a port storm mode is activated under pressure. In port storm mode, the target port can accept and transmit a large number of data packets. Port storm mode is used to simulate a situation where a large number of network ports are attacked simultaneously to test the performance and defense capabilities of network devices. In port storm mode, the testing tool generates a large amount of fake traffic and attempts to connect to multiple ports of the target host to simulate a real network attack scenario. This test can help testers identify potential security vulnerabilities and performance bottlenecks and take corresponding measures to improve them. After a certain period of execution, i.e., the control period, the log information is read again to determine whether there is packet loss, latency anomalies, and / or disconnection, in order to test the performance of the target port and the cable under test.

[0092] More specifically, if there is a reliability risk, meaning the device cannot withstand port storm mode output, it should be returned for repair. Details are as follows:

[0093] If the packet loss, latency anomaly, and / or connection failure occurs, a reliability anomaly warning message will be sent.

[0094] Perform fault repair based on the reliability anomaly message until there are no more packet loss, latency anomalies, or connection drops.

[0095] Specifically, if, after port storm mode, packet loss, incorrect latency, or link failure (link down in network communication refers to the link state between two devices becoming LINK DOWN when the connection between them is broken or communication is impossible, which may be due to physical layer failure, configuration error, or other reasons) occurs, then the maintenance steps are returned according to the corresponding exception type. After maintenance, the initial steps are returned, that is, steps S1-S6 are repeated until it is determined that there are no reliability exceptions at the port to ensure cable quality.

[0096] In step S7, if there is no packet loss, delay anomaly, and / or disconnection, then the cable under test is determined to have completed the cable test.

[0097] Specifically, once it is confirmed that the above-mentioned situations do not exist, the performance and reliability of the product are ensured. In this case, the testers can mark the corresponding product as qualified and proceed to the packaging step by marking or other means.

[0098] In another aspect, this application discloses a testing system for active optical cables; please refer to [link to relevant documentation]. Figure 2 , Figure 2 This is a virtual structural diagram of the active optical cable testing system provided in this application. The active optical cable testing system includes:

[0099] Test command acquisition module 100 is used to acquire test commands for the cable under test;

[0100] The first anomaly judgment module 200 is used to determine whether there is a connection anomaly according to the test command of the cable under test. The connection anomaly is an abnormal state such as no cable is inserted into the target port, no normal connection, and / or inconsistent speed.

[0101] The interference data clearing module 300 is used to clear interference data if there is no connection abnormality. The interference data includes residual information generated after the most recent batch of tested cables were disconnected and access information of the cable to be tested.

[0102] The port information acquisition module 400 is used to acquire the port information of the target port, the port information including bit error rate and signal quality;
