[0010] This application provides an intelligent monitoring system and method for 400G coherent optical modules, which solves the technical problem that existing 400G coherent optical modules are prone to loss of lock during band switching, affecting communication stability.

[0011] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0012] It should be noted that the terms "first," "second," etc., in the specification and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or server that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or modules not explicitly listed or inherent to such processes, methods, products, or devices.

[0013] Example 1, as Figure 1 As shown, this application provides an intelligent monitoring system for a 400G coherent optical module, the system comprising: The historical band switching data acquisition module 10 is used to load historical band switching data of the 400G coherent optical module within a preset period. The historical band switching data includes historical band received signals, band switching type tags, band signal transmission environment information, and accuracy tags characterizing the band signal reception accuracy. The band switching type tags at least include switching types from C-band to L-band and from L-band to C-band. Furthermore, the 400G coherent optical module also includes an extension module, which extends multiple bands and updates multiple band switching type tags based on these multiple bands.

[0014] Furthermore, when acquiring the accuracy tag that characterizes the accuracy of band signal reception, the historical band switching data acquisition module 10 is also used to perform the following steps: P11: performing band accuracy evaluation on the historical band received signal, including wavelength attenuation slope, filter loss gain, and signal bit error rate; P12: performing weight calculation on the wavelength attenuation slope, filter loss gain, and signal bit error rate to obtain an accuracy label representing the band signal receiving accuracy of the historical band received signal.

[0015] It should be understood that the main task of the historical band switching data acquisition module 10 of the present application is to load and process the historical band switching data of the 400G coherent optical module within a preset period, to provide a decision basis based on historical data for the system.

[0016] Firstly, the historical band switching data contains multiple important data items, including historical band received signal, band switching type label, band signal transmission environment information, and accuracy label. Among them, the historical band received signal is the signal intensity received by the 400G coherent optical module under different bands. The band switching type label is used to clearly identify the switching type between different bands. For example, the switching type of C band to L band, and the switching type of L band to C band, etc. The band switching type label at least includes the switching type of C band to L band and the switching type of L band to C band, and the system can distinguish the type and characteristics of different band switching through these labels. The band signal transmission environment information records the environmental changes in the transmission process, such as temperature, humidity and other external factors, which will affect the transmission quality of the band signal. And the accuracy label is used to represent the accuracy of the band signal receiving, and the accuracy label is generated based on the evaluation of the signal quality.

[0017] Among them, the accuracy label is the core index to measure the quality of band signal receiving, which comprehensively evaluates the accuracy and reliability of the signal through multiple key parameters. Specifically, in obtaining the accuracy label representing the band signal receiving accuracy, firstly, the historical band received signal is evaluated for band accuracy, and the evaluation content includes wavelength attenuation slope, filter loss gain, and signal bit error rate. The wavelength attenuation slope is the degree of attenuation caused by wavelength change in the signal transmission process, which can reflect the transmission loss of the signal under different bands; the filter loss gain is the influence of the signal through the filter, and the gain or loss of the signal may occur in the filtering process; the signal bit error rate (BER) is a key indicator to evaluate the quality of signal transmission, which represents the error proportion between the received signal and the transmitted signal. Each evaluation indicator represents a dimension of signal quality.

[0018] Next, based on the pre-set weight distribution model, the wavelength attenuation slope, filter loss gain and signal bit error rate are comprehensively weighted to generate an accuracy label. Among them, the influence degree of each factor on the final accuracy label is different, and the weight of each evaluation index can be calculated by experience rule or regression analysis based on historical data. For example, the signal bit error rate may have a more significant impact on the accuracy than the wavelength attenuation slope, so its weight will be higher. In this way, the influence of different factors can be considered to allocate weight coefficients, and the final accuracy label is calculated according to these weights to indicate the accuracy of the received signal of a specific wavelength band.

[0019] On this basis, the 400G coherent optical module further includes an expansion module for expanding multiple wavelength bands to cope with more complex wavelength switching requirements. As the number of wavelength bands increases, the wavelength switching type label will also be updated to cover more wavelength switching cases. For example, when the expansion module introduces a new O wavelength band, the wavelength switching type label will be updated in time to add new switching types such as C wavelength switching to O wavelength, O wavelength switching to L wavelength, etc. This enables the system to cope with more complex wavelength switching tasks and improves the flexibility and reliability of wavelength switching.

[0020] The wavelength boundary locking template construction module 20 is configured to construct a wavelength boundary locking template based on the historical wavelength switching data.

[0021] Further, the wavelength boundary locking template construction module 20 is further configured to perform the following steps: P21: collect a first group of historical wavelength switching data of C wavelength switching to L wavelength, and a second group of historical wavelength switching data of L wavelength switching to C wavelength; P22: take the historical wavelength received signal and wavelength signal transmission environment information corresponding to the first group of historical wavelength switching data and the second group of historical wavelength switching data as input data, take the wavelength boundary as a variable space, and take the accuracy label corresponding to the first group of historical wavelength switching data and the second group of historical wavelength switching data as a supervision label to perform regression analysis, to obtain a wavelength boundary regression model; P23: construct a wavelength boundary locking template based on the wavelength boundary regression model.

[0022] Optionally, the main function of the wavelength boundary locking template construction module 20 of the present application is to construct an intelligent locking template for adjusting the wavelength boundary by analyzing the historical wavelength switching data. The template can dynamically adjust the wavelength boundary according to the historical data during the actual wavelength switching process to ensure the stability and signal quality during the switching process.

[0023] In the process of constructing the band boundary locking template, first, the band boundary locking template construction module 20 needs to collect two sets of specific historical band switching data. The first set of data comes from the switching data from C band to L band, and the second set of data comes from the switching data from L band to C band. These two sets of data cover different conditions and characteristics of switching between different bands, including band signal reception, band signal transmission environment information, and accuracy label information during actual switching. Through these historical data, detailed background information about band switching can be obtained, including band signal quality, transmission environment, and corresponding accuracy.

[0024] Next, the historical band reception signals and band signal transmission environment information corresponding to the first set of historical band switching data and the second set of historical band switching data are used as input data. These data include signal strength under different bands, influencing factors of transmission environment, etc., and the accuracy labels in each set of data are used as supervision labels. At the same time, taking the band boundary as the adjustable variable space, the accuracy labels corresponding to the first set and the second set of historical band switching data are used as supervision labels. Through regression analysis method, the input data and supervision labels are processed to obtain a band boundary regression model. This regression model can reveal the internal relationship between the band boundary and the signal reception accuracy, providing a theoretical basis for subsequent band boundary locking.

[0025] Finally, based on the obtained band boundary regression model, a band boundary locking template is constructed, which integrates and encapsulates the key parameters and rules in the band boundary regression model to form a template that can be called in real time. In the subsequent band switching process, the system can quickly and accurately adjust the band boundary according to the parameters and rules in the band boundary locking template, thereby effectively avoiding the occurrence of band loss of lock phenomenon and ensuring the stable transmission of communication signals.

[0026] Further, in the band boundary locking template construction module 20: The band boundary regression model includes a first interval regression model for switching from C band to L band, and a second interval regression model for switching from L band to C band; the band switching type of the band switching instruction is disassembled, and the real-time band switching data is analyzed according to the first interval regression model or the second interval regression model according to the band switching type.

[0027] In a possible embodiment of the present application, in the construction of the band boundary regression model, the band boundary locking template construction module 20 can also accurately apply the corresponding regression model for analysis according to different band switching types, thereby further improving the accuracy and reliability of band switching.

[0028] Specifically, the band boundary regression model includes a first interval regression model for C-band switching to L-band and a second interval regression model for L-band switching to C-band. These two regression models are used to process data of different band switching types, and can provide more accurate band boundary adjustment suggestions for different switching directions and band characteristics.

[0029] When the band boundary locking template construction module 20 receives a band switching instruction, it first disassembles the instruction to determine the specific band switching type. This process can be achieved by analyzing the key information in the band switching instruction, such as disassembling using the specified starting band and target band in the instruction, and according to the disassembly result, determining whether the current band switching is C-band switching to L-band or L-band switching to C-band. According to the different types of switching, the corresponding interval regression model can be selected to analyze the real-time band switching data. For example, for the case of C-band switching to L-band, the first interval regression model can be called for analysis, while for the case of L-band switching to C-band, the second interval regression model can be used. This targeted analysis method can fully utilize the characteristics and advantages of each interval regression model, ensuring that the analysis results of real-time band switching data are more accurate and reliable.

[0030] Through this design, the band boundary locking template construction module 20 can more accurately dynamically adjust the band boundary according to different band switching types, optimize the performance of the 400G coherent optical module in various band environments, and ensure that the system can still maintain a high-efficiency and stable working state during complex band switching processes.

[0031] Further, the band boundary locking template construction module 20, after obtaining the band boundary regression model, is further configured to perform the following steps: P22-1a: training a generator according to the band boundary regression model, the generator being configured to obtain incremental band switching data of the historical band switching data; P22-2a: incrementally optimizing the band boundary regression model according to the incremental band switching data, and outputting an optimized band boundary regression model.

[0032] Specifically, after the band boundary regression model is initially constructed, the band boundary locking template construction module 20 can further improve the accuracy and adaptability of the model through an incremental optimization mechanism.

[0033] After obtaining the band boundary regression model, a generator is first trained through the band boundary regression model. The main function of the generator is to generate incremental band switching data related to historical band switching data based on the existing band boundary regression model. These incremental data are not simply copied from the historical data, but are generated through the prediction and simulation functions of the band boundary regression model to generate new band switching data with certain changes and diversity. These data can reflect new situations that may occur under different environmental conditions, different signal quality conditions, and different band switching types. Specifically, the generator will use the parameters and rules in the band boundary regression model, combined with certain randomness and change rules, to generate new band receiving signals, band signal transmission environment information, and corresponding accuracy labels, that is, incremental band switching data. These incremental band switching data can supplement the deficiencies of historical data, increase the richness and coverage of data, and thus provide more comprehensive training materials for subsequent model optimization.

[0034] After obtaining the incremental band switching data, the band boundary locking template construction module 20 will perform incremental optimization on the existing band boundary regression model based on these new data. By using the incremental data as new training samples, the model can learn more new features and rules, thereby improving its adaptability and prediction accuracy for different band switching situations. For example, during the incremental optimization process, the band boundary regression model will adjust its internal parameters and weights according to the input features in the incremental data, such as band receiving signals, band signal transmission environment information, and corresponding supervision labels (accuracy labels). The adjustment process can be based on optimization algorithms of regression analysis, such as least squares method, gradient descent method, etc., to minimize the error between the model prediction value and the actual accuracy label. Unlike traditional batch training methods, incremental optimization can reduce repeated training on all historical data, save computing resources, and can adjust the model in real time as new data is added, ensuring that it adapts to new environments and band switching patterns.

[0035] Finally, after completing the incremental optimization, the optimized band boundary regression model is evaluated to verify its performance on new data. If the performance of the model meets the expected standard, it will be used as the new band boundary regression model for subsequent band boundary locking template construction and real-time band switching adjustment. Through this incremental optimization mechanism, the band boundary regression model can continuously learn and improve in actual application, ensuring that its performance is continuously improved in the long run, and it can better cope with changes in the communication environment and new band switching requirements.

[0036] Further, the band boundary locking template construction module 20, when constructing the band boundary locking template based on the band boundary regression model, is further configured to perform the following steps: P23-1: cluster the band signal transmission environment information of the first set of historical band switching data, obtain a plurality of representative transmission environment information, obtain the preferred band boundary corresponding to the plurality of representative transmission environment information according to the first interval regression model, and construct a first band boundary locking template; P23-2: cluster the band signal transmission environment information of the second set of historical band switching data, obtain a plurality of representative transmission environment information, obtain the preferred band boundary corresponding to the plurality of representative transmission environment information according to the second interval regression model, and construct a second band boundary locking template; P23-3: construct a band boundary locking template according to the first band boundary locking template and the second band boundary locking template.

[0037] Optionally, in the band boundary locking template construction module 20, the process of constructing the band boundary locking template can be further refined. By further analyzing the historical data in detail, the accuracy and adaptability of the template can be improved.

[0038] First, the first set of historical band switching data (C band switching to L band data) is clustered by band signal transmission environment information, similar transmission environment information is classified into a category, and a plurality of representative transmission environment information, that is, representative transmission environment information, is obtained. These representative transmission environment information can cover band switching under different conditions, providing diversified reference points for subsequent band boundary optimization.

[0039] Next, using the first interval regression model, the corresponding preferred band boundary is calculated for these representative transmission environment information. The first interval regression model is specially constructed for the case of C band switching to L band, so it can accurately calculate the preferred band boundary most suitable for the environment according to the different transmission environments. Integrating these preferred band boundaries into the first band boundary locking template can be used to guide the band boundary adjustment of C band switching to L band.

[0040] Similarly, the second set of historical band switching data is clustered by band signal transmission environment information to obtain a plurality of representative transmission environment information. Then, using the second interval regression model, the corresponding preferred band boundary is obtained for these representative transmission environment information. Based on these preferred band boundaries, a second band boundary locking template is constructed to guide the band boundary adjustment of L band switching to C band.

[0041] Finally, the first waveband boundary locking template and the second waveband boundary locking template are integrated to construct a complete waveband boundary locking template. This final waveband boundary locking template will combine the switching requirements of C-band to L-band and L-band to C-band, providing a set of waveband boundary settings suitable for different waveband switching conditions. The template not only considers historical data and regression analysis results, but also optimizes waveband boundary values according to different transmission environments, ensuring that the system can maintain high performance in complex practical application environments.

[0042] The real-time waveband switching data monitoring module 30 is used to determine whether the 400G coherent optical module receives a waveband switching instruction. If the 400G coherent optical module receives a waveband switching instruction, real-time waveband switching data obtained by monitoring is acquired.

[0043] It should be understood that the task of the real-time waveband switching data monitoring module 30 of the present application is to monitor in real time whether the 400G coherent optical module receives a waveband switching instruction, and to acquire relevant real-time waveband switching data in time after receiving the instruction. In order to achieve this goal, the real-time waveband switching data monitoring module 30 first needs to effectively determine whether there is a waveband switching instruction input. These instructions are usually issued by the control center of the system or other modules, and are used to inform the 400G coherent optical module to switch to a specified waveband. The waveband switching instruction needs to include explicit waveband switching requirements, such as switching from C-band to L-band, or switching from L-band to C-band, etc.

[0044] When receiving the waveband switching instruction, the real-time waveband switching data monitoring module 30 will enter an active state and begin to monitor the real-time waveband data related to the current waveband switching, that is, to acquire the waveband information involved in the current switching instruction, including the reception quality of the signal, the transmission environment of the waveband signal, and the accuracy of signal reception, etc. Through these data, the performance of the waveband after switching can be fully understood, and key performance indicators such as signal strength, noise interference, and bit error rate can be evaluated to ensure that the signal quality after waveband switching meets the expected requirements.

[0045] In addition, the real-time waveband switching data monitoring module 30 also records the transmission environment information of the waveband signal, including environmental influences that may be encountered during transmission, such as temperature changes, humidity fluctuations, and other factors that may interfere with the signal. Through continuous monitoring of these environmental information, the performance of waveband switching under different environments can be evaluated, thereby providing a basis for subsequent waveband adjustment. At the same time, the accuracy of waveband signal reception needs to be monitored, including wavelength attenuation slope, filtering loss gain, and signal bit error rate parameters. Real-time monitoring of these parameters can help the system evaluate the signal quality during waveband switching and ensure the reliability of waveband switching.

[0046] During the band switching process, the real-time band switching data monitoring module 30 can constantly update and provide the signal state of the current band, ensuring that other modules can adjust the band boundary according to the latest data to avoid the phenomenon of band loss of lock, and ensuring that the 400G coherent optical module always maintains stable signal transmission during band switching.

[0047] The band boundary adjustment module 40 is configured to analyze the real-time band switching data using the constructed band boundary locking template, obtain a first band boundary corresponding to the band switching instruction, and adjust the band boundary of the tunable laser in the 400G coherent optical module based on the first band boundary.

[0048] Further, when the band boundary adjustment module 40 analyzes the real-time band switching data using the constructed band boundary locking template, it is further configured to perform the following steps: P41: Extract the band signal transmission environment information in the real-time band switching data; P42: Extract the band signal transmission environment information template of the band boundary locking template, match the band signal transmission environment information based on the band signal transmission environment information template, and obtain a matching band boundary; P43: Output the matching band boundary as the first band boundary corresponding to the band switching instruction.

[0049] Optionally, the main task of the band boundary adjustment module 40 of the present application is to analyze and adjust the band boundary using real-time band switching data based on the constructed band boundary locking template, so as to ensure that the 400G coherent optical module can accurately adjust the band setting of the laser during band switching, thereby improving the system stability and signal quality.

[0050] When performing band boundary adjustment, the band boundary adjustment module 40 first extracts the band signal transmission environment information from the real-time band switching data, including the transmission conditions of the current band, such as temperature, humidity, distance and other factors that may affect signal quality. These environmental factors have a significant impact on the quality and stability of the signal. By extracting this information, the band boundary adjustment module 40 can understand the specific environmental conditions under which the current band switching is taking place.

[0051] Next, the waveband signal transmission environment information template in the waveband boundary locking template is extracted. This template is constructed based on the historical data and the waveband boundary regression model after incremental optimization, and contains a variety of representative transmission environment information and the corresponding preferred waveband boundary. The waveband boundary adjustment module 40 can match the waveband signal transmission environment information in the real-time waveband switching data with the information in the waveband boundary locking template, and find the closest matching item through algorithm analysis. For example, a plurality of parameters can be comprehensively evaluated to obtain a matching waveband boundary, such as by calculating the similarity of real-time environment information and template environment information, or by predicting the optimal waveband boundary under the current environment through the regression model, to obtain a specific waveband boundary, i.e. the matching waveband boundary.

[0052] Finally, the obtained matching waveband boundary is output as the first waveband boundary corresponding to the waveband switching instruction, and the precise setting of this waveband boundary is realized by adjusting the tunable laser in the 400G coherent optical module. This first waveband boundary is the result of optimization based on the current transmission environment and historical data, and can effectively guide the precise waveband boundary adjustment of the tunable laser in the 400G coherent optical module, so that the 400G coherent optical module can automatically adapt to different environmental conditions and waveband switching requirements, and effectively avoid the loss of lock during the waveband switching process.

[0053] Further, the waveband boundary adjustment module 40 is also used to perform the following steps: P44: matching the waveband signal transmission environment information based on the waveband signal transmission environment information template, if the matching is unsuccessful, re-calling the first interval regression model or the first interval regression model for prediction, and outputting a predicted waveband boundary; P45: outputting the predicted waveband boundary as the first waveband boundary corresponding to the waveband switching instruction.

[0054] Specifically, during the execution of the waveband boundary adjustment process, the waveband boundary adjustment module 40 not only relies on the matching of the waveband signal transmission environment information template, but also adds an emergency mechanism to deal with matching failure, which can ensure that in some cases the environment information template cannot be successfully matched with real-time data, the system can still predict a suitable waveband boundary through the regression model, thereby avoiding problems such as waveband loss or unstable signal.

[0055] In the matching process, first, based on the constructed band signal transmission environment information template, attempt to match the band signal transmission environment information in the real-time band switching data. When the system successfully matches the environment information template, a suitable matching band boundary can be directly generated. However, if the matching based on the band signal transmission environment information template is unsuccessful in the matching process, that is, no template item matching the current transmission environment information can be found, the emergency mechanism is triggered. In this case, the band boundary adjustment module 40 will re-call the first interval regression model or the second interval regression model for prediction. Which interval regression model to call depends on the type of band switching instruction. For example, if the band switching instruction is to switch from C band to L band, the first interval regression model is called; if it is to switch from L band to C band, the second interval regression model is called. Through the prediction of the regression model, a predicted band boundary is output, which is based on the current transmission environment information and the prediction result of the regression model.

[0056] Then, the predicted band boundary is used as the first band boundary output corresponding to the current band switching instruction. This predicted band boundary is obtained through the analysis of the regression model, taking into account the current transmission environment information and the regularity in the historical data, and thus can provide a reasonable band boundary adjustment suggestion for the tunable laser in the 400G coherent optical module. Even in the case of unsuccessful matching, the band boundary adjustment module 40 can ensure the stability and reliability of the band switching process through the prediction ability of the regression model. Finally, this predicted band boundary will ensure that the band boundary setting of the tunable laser in the 400G coherent optical module accurately meets the current band switching requirements, thereby ensuring the stability and quality of signal transmission.

[0057] In summary, the embodiments of the present application have at least the following technical effects: Through intelligent band boundary adjustment, the present application can improve the stability of band switching, reduce the phenomenon of band loss, and ensure the signal quality and system stability during band switching; by using historical data and real-time monitoring to dynamically adjust the band boundary, the adaptive ability of the system is enhanced, so that it can optimize the transmission performance according to different band switching requirements and environmental changes; by accurately adjusting the band boundary, the efficiency and reliability of the 400G coherent optical module in the multi-band switching environment are improved, and the utilization of system resources is optimized, avoiding unnecessary waste of resources.
