[0048] Figure 3 This is a schematic diagram of the optical module transmission detection system in an embodiment of the present invention. Detailed Implementation
[0049] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0050] Example 1:
[0051] Figure 1 A flowchart of an optical module transmission detection method according to an embodiment of the present invention is shown. The detection method is applicable to an optical module system, which includes: a plurality of optical module units, a transmitting end unit, and a receiving end unit. The detection method includes:
[0052] S11: Input the detection optical signal into the transmitting unit and match the detection optical signal to the signal transmission path.
[0053] Specifically, the detection optical signal refers to a specific optical signal used to test the transmission performance of the optical module. It can be implemented using light waves with preset wavelengths and power to ensure that the signal has identifiable characteristics during transmission, which facilitates subsequent data comparison and analysis.
[0054] The signal transmission path refers to the channel through which the detection optical signal travels from the transmitting end to the receiving end. Specifically, it can be defined by the pre-configured connection relationship of optical module units to ensure that the detection signal can cover all optical module units under test, thereby realizing the integrity detection of the transmission channel.
[0055] Furthermore, the detection optical signal is input into the transmitting unit, and the signal transmission path for matching the detection optical signal includes:
[0056] By randomly generating numerical arrangement data as detection data, the detection data is input into the transmitting unit, so that the transmitting unit generates a detection optical signal based on the detection data;
[0057] Several signal transmission paths are obtained in the optical module system, and the detection optical signal is sequentially input into the several signal transmission paths.
[0058] In an optical module system, the transmitting unit can employ programmable logic devices to generate the detection optical signal and perform transmission path matching. The detection optical signal can be a preset pseudo-random bit sequence, which is converted into an analog signal by a digital-to-analog converter and then drives the laser to emit. Transmission path matching can be achieved through an optical switch matrix, which automatically switches between different fiber optic link combinations according to a preset detection strategy.
[0059] The receiving unit can use a high-speed photodetector to receive the detection optical signal and convert the optical signal into a digital data stream through an analog-to-digital converter. The data acquisition module can record the received detection optical signal data in real time and transmit it to the data processing unit through a high-speed interface.
[0060] This application further proposes to use randomly generated numerical arrangement data as detection data, input the detection data into the transmitting unit to generate a detection optical signal, and obtain several sets of signal transmission paths in the optical module system, and input the detection optical signal into several sets of signal transmission paths in sequence.
[0061] The random generation of numerical permutations can be achieved using a linear congruential algorithm or a Mason truncation algorithm, with the generated data length being either 64 bits or 128 bits. The randomness of the data permutation during detection data generation can be achieved by setting different random seed values, such as using a timestamp as the seed parameter. When acquiring the signal transmission path, all possible link combinations can be traversed based on the topology of the optical module system. For example, for a system containing 5 optical module units, at least 3 different cascaded path configurations can be extracted. When the detection optical signal is injected sequentially into different paths, the duration of each injection can be set from 50ms to 200ms, and the switching interval between adjacent paths must maintain a buffer time of no less than 10ms. Through the combination of random data generation and multi-path traversal, dual coverage of dynamic changes in the signal source and changes in transmission channel combinations can be achieved, avoiding the limitations of fixed data patterns and single transmission paths in traditional methods.
[0062] Specifically, the transmitting unit receives a digital sequence generated by a random algorithm and converts it into an optical signal with a specific wavelength and power. This optical signal is then distributed to different pre-extracted transmission paths. Since different transmission paths involve different combinations of optical module units, this can be used for comparative analysis to determine the transmission loss status of each optical module unit within the optical module system, as well as the transmission loss between different optical module units. This allows maintenance personnel to perform precise maintenance based on different loss conditions, improving the accuracy of optical module performance evaluation in complex networking environments.
[0063] S12: Based on the signal transmission path, the detection optical signal is sent to the receiving unit to obtain the detection optical signal data.
[0064] Furthermore, the step of sending the detection optical signal to the receiving unit based on the signal transmission path and acquiring the detection optical signal data includes:
[0065] The receiving unit acquires the detection optical signal data of the signal transmission path and sends the detection optical signal data to the optical channel monitoring module.
[0066] The receiving unit can acquire detection optical signal data along the signal transmission path using a photodetector. The photodetector converts the optical signal into an electrical signal, and then the electrical signal is converted into a digital signal using an analog-to-digital converter. The receiving unit can be equipped with a data buffer module for temporarily storing the acquired detection optical signal data. The optical channel monitoring module can be equipped with a data receiving unit for receiving detection optical signal data from the receiving unit.
[0067] Through the above technical solution, this application achieves accurate acquisition and efficient transmission of optical signal data. The receiving unit, as the terminal node for data acquisition, directly captures the optical signal state in the transmission path, avoiding data distortion that may be caused by intermediate links. By establishing a direct data transmission link from the receiving unit to the optical channel monitoring module, the integrity and timeliness of the data are ensured. This directional transmission mechanism significantly improves the accuracy of data transmission, providing reliable data input to the optical channel monitoring module, thereby improving the accuracy of subsequent calculations of transmission deviation values by the optical module units. Simultaneously, this method simplifies the data flow, reduces intermediate steps in data processing, and improves the overall system response speed and efficiency.
[0068] S13: During the detection of optical signal transmission, acquire the optical signal transmission data of each optical module unit within the signal transmission path.
[0069] The optical channel monitoring module detects the optical signal data of each optical module unit within the signal transmission path, acquiring the optical signal data of each optical module unit within the signal transmission path. The optical channel monitoring module may include multiple distributed detection units, each corresponding to one optical module unit. The detection unit may employ a photodetector, such as a photodiode or photomultiplier tube, to capture the optical signal and convert it into an electrical signal.
[0070] Furthermore, each detection unit can be equipped with a signal processing circuit to amplify, filter, and digitize the captured signal, thereby acquiring the transmission data of the detection optical signal in each optical module unit to detect the transmission integrity of the detection optical signal data within the optical module system.
[0071] The optical channel monitoring module can independently detect optical signal data for each optical module unit within the signal transmission path, thereby accurately locating data anomalies in each optical module unit on the signal transmission link. This distributed detection method improves the granularity of data acquisition, enabling the system to monitor the performance status of each optical module unit in real time. Therefore, this solution solves the problem of traditional holistic monitoring methods struggling to identify specific fault points, improving the maintenance efficiency and reliability of the optical module system. Furthermore, by achieving synchronization between real-time monitoring and data acquisition, this solution can promptly detect and locate potential problems in the transmission link, facilitating preventative maintenance and rapid fault diagnosis.
[0072] Furthermore, the step of detecting optical signal data for each optical module unit within the signal transmission path through the optical channel monitoring module, and acquiring the optical signal transmission data of each optical module unit within the signal transmission path, includes:
[0073] A data processing module is set in the optical module unit, and an optical transmission signal is generated after the acquired detection optical signal data is parsed by the data processing unit.
[0074] The optical transmission signal is sent to the optical channel monitoring module, and optical transmission data is generated based on the optical channel monitoring module.
[0075] Specifically, when the detection optical signal enters the optical module unit, it undergoes localized processing by the built-in data processing module. The detection optical signal received by the optical module unit can pass through a bandpass filter circuit to eliminate environmental noise, and then be converted into a digital signal by an analog-to-digital converter. During the data parsing stage, effective signal parameters are extracted and encapsulated into structured data packets containing timestamps and module identifiers. The processed optical transmission signal is transmitted to the optical channel monitoring module through a standardized communication interface. After receiving the data in a unified format, the monitoring module can directly calculate the deviation value without additional data cleaning. Through the combination of localized processing and standardized transmission, the optical channel monitoring module can simultaneously process data streams from multiple optical module units, realizing real-time calculation and comparative analysis of transmission deviation values.
[0076] S14: Calculate the transmission deviation value of each optical module unit in the signal transmission path by combining the detected optical signal data and several optical signal transmission data.
[0077] Specifically, Figure 2 A flowchart of an optical module transmission detection calculation method according to an embodiment of the present invention is shown. The optical module transmission detection calculation method includes:
[0078] S141: Set the detection optical signal of the transmitting unit as the basic data.
[0079] Using the detection optical signal from the transmitting unit as the basic data, the detection optical signal data acquired by several optical module units and the receiving unit are calculated and analyzed based on the detection optical signal from the transmitting unit. This allows for the acquisition of the data transmission status of the detection optical signal at different locations within the optical module system, thereby improving the detection reliability of the optical module system.
[0080] S142: Calculate variance data based on the basic data combined with the detected optical signal data and optical signal transmission data.
[0081] Specifically, the formula for calculating the variance data is as follows:
[0082] ;
[0083] in, The data represents variance, where N is the counting constant and M is the number of optical module units. When N ≤ M, For transmitting data via optical signals, when N=M+1, To detect optical signal data, To detect optical signals.
[0084] S143: Calculate the standard deviation data of the receiving unit and several optical module units in the signal transmission channel in sequence.
[0085] The formula for calculating the standard deviation data is as follows:
[0086] ;
[0087] Where N is a counting constant, and M is the number of optical module units. Here is the standard deviation data for the Nth optical module unit, where N ≤ M. For transmitting data via optical signals, when N=M+1, The detection optical signal data acquired by the receiving unit The detection optical signal is input to the transmitting unit;
[0088] In this embodiment, by establishing unified benchmark data and calculating variance and standard deviation, quantitative analysis of data fluctuations at each stage of the signal transmission path is achieved, accurately reflecting the transmission loss of the detection optical signal by each optical module unit. Calculating the deviation value according to the transmission sequence allows for accurate location of the optical module unit where abnormal fluctuations occur. This method improves the accuracy of detection and evaluation, providing reliable data support for assessing the transmission performance of optical module units.
[0089] S144: Loop counting judgment.
[0090] Specifically, it is determined whether N satisfies N=M+1. If not, N=N+1 is adjusted, and the process returns to step S143 to calculate and analyze the standard deviation data. If yes, the standard deviation data obtained in step S143 are summarized to calculate the transmission deviation value, so as to achieve accurate analysis of the optical signal transmission loss between each optical module unit in the signal transmission channel.
[0091] Furthermore, based on the cyclic counting judgment, it is determined whether the calculation of the standard deviation data has reached the position of the receiving end unit. The calculation is performed in a segmented manner, and the standard deviation data of each optical module unit and the receiving end unit are calculated sequentially along the signal transmission path of the signal transmission channel. This enables accurate analysis of the location of transmission error loss in the optical module system, so as to achieve precise maintenance.
[0092] S145: Calculate the transmission deviation value of each optical module unit according to the transmission sequence of the signal transmission channel.
[0093] Furthermore, according to the transmission path of the detected optical signal within the signal transmission channel, the transmission deviation values of several optical module units and the transmission deviation values of the receiving unit are sorted.
[0094] The transmission deviation value of the receiving end unit and each optical module unit is calculated using the following formula:
[0095] ;
[0096] Where N≤M, This represents the transmission deviation value of the optical module unit. This represents the standard deviation data of the current optical module unit. This represents the standard deviation data of the adjacent previous optical film block unit;
[0097] When N=M+1 The transmission deviation value of the receiving unit. This is the standard deviation data of the receiving unit. This represents the standard deviation data of the adjacent previous optical film block unit.
[0098] The calculation method for optical module transmission detection eliminates the cumulative error caused by the cascading of multiple optical module units in the transmission path, enabling precise separation of the independent deviation of each unit. During implementation, the standard deviation data of each unit can be collected in real time through the optical channel monitoring module, and the difference calculation is automatically performed based on the sorted path order, thereby dynamically generating a transmission deviation evaluation result.
[0099] S15: Compare the transmission deviation values of each optical module unit to generate detection and evaluation data for each optical module unit.
[0100] Furthermore, the step of comparing the transmission deviation values of each optical module unit to generate detection and evaluation data for each optical module unit includes:
[0101] The transmission deviation values of several optical module units are compiled into a line graph. The slope of any two adjacent data points is calculated based on the line graph. The line graph can intuitively reflect the loss changes between various optical module units during the transmission of the detection optical signal, so as to accurately locate the location of detection optical signal loss and thus achieve precise maintenance.
[0102] Several sets of slope data are calculated in the line graph of the transmission deviation value, and the mean of the several sets of slope data is calculated. The slope data with a slope value greater than the mean of the several sets of slope data are marked as defect data, that is, the corresponding optical module unit has a large optical signal transmission loss, and maintenance personnel need to carry out detailed inspection and maintenance.
[0103] Slope data with slope values less than the mean in several sets of slope data are marked as normal data, which reflects that the optical signal transmission performance of the corresponding optical module unit is within the normal error range and can meet the signal transmission requirements of the optical module system.
[0104] Furthermore, slope calculation and analysis using line graphs can effectively solve the problem that traditional discrete numerical comparison methods cannot identify signal abrupt changes between adjacent modules. By converting transmission deviation values into continuous line graphs and analyzing the slope change trends of adjacent data points, abnormal fluctuation characteristics in the signal transmission process can be accurately captured. Using dynamically calculated mean values as the discrimination threshold, analysis can be performed based on the difference between various transmission deviation values, avoiding interference from external parameters, thereby improving detection efficiency. This allows maintenance personnel to quickly locate defective optical module units and ensure the stable operation of the optical signal transmission system.
[0105] This invention provides an optical module transmission detection method applicable to optical module systems comprising multiple optical module units, transmitting units, and receiving units. First, a detection optical signal is input to the transmitting unit and a transmission path is matched to ensure the detection signal can traverse all possible optical module transmission channels. Then, the detection optical signal is sent to the receiving unit based on the specified path, and the detection optical signal data is acquired as a terminal reference. During signal transmission, optical signal transmission data of each optical module unit is collected in real time, establishing module-level data monitoring capabilities. Next, combining the original data from the transmitting end and the transmission data of each module, the signal loss degree of each optical module unit is quantified by calculating the transmission deviation value. Finally, the deviation values of each module are compared to generate evaluation data that can locate specific defective modules, achieving hierarchical diagnosis of multi-level optical module transmission systems.
[0106] This method overcomes the limitation of traditional end-to-end monitoring schemes, which cannot locate specific abnormal modules, by enabling module-level performance monitoring without interrupting service transmission. It extracts key transmission indicators by reusing existing signal processing units within the optical module unit, avoiding the complexity and cost of adding extra hardware. By establishing a recursive relationship model for transmission deviation values, the location of abnormal modules can be reversed, improving the accuracy and efficiency of fault diagnosis.
[0107] This invention provides a method for detecting the transmission of optical modules. By setting a detection optical signal to perform transmission detection within the optical module system, and based on the detection optical signal traversing each signal transmission channel within the optical module system, the detection requirements for each optical module unit of the optical module system are met. By calculating the transmission deviation value of each optical module unit, accurate detection within the optical module system is achieved, thereby improving the accuracy and reliability of the transmission detection of the optical module system.
