Technical Field

[0002] This application relates to the field of optical communication, and more particularly to a monitoring method for an optical module, an optical module, and an optical communication device. Background Technology

[0003] With the growth of internet traffic and data volume, optical modules, as key components in optical communication that enable optical signal transmission and electrical signal conversion, have become increasingly important. The performance of optical modules directly affects the stability and efficiency of the entire communication system. Therefore, to ensure the operation of optical modules, intelligent monitoring and diagnosis, such as long-term operational data analysis, long-term reliability assurance, rapid problem identification, and early warning, have become a major focus of the optical communication industry. However, currently, optical modules often operate independently, logging data without connecting to other devices. When these logs are retrieved externally, accurate data analysis is difficult. Therefore, improving the universality of optical module logging is a pressing technical problem that needs to be solved. Summary of the Invention

[0004] This application provides a monitoring method for an optical module, an optical module, and an optical communication device to improve the versatility of the optical module's log recording.

[0005] Firstly, a monitoring method for an optical module is provided. This method can be executed by the optical module. Unless otherwise specified, the term "optical module" in this application can refer to the optical module itself, a component within the optical module (e.g., a processor, chip, or chip system), or a logic module or software capable of implementing all or part of the functions of the optical module device. The optical module is plugged into the interface of a first device and includes a transceiver module, a processing module, and a log generation module.

[0006] The method includes: a transceiver module receiving first information from a first device, the first information indicating a first time determined by the first device; a processing module parsing the first information to obtain the first time; and a log generation module recording a first log based on the first information. By utilizing the parent device of the optical module to send the current time to the optical module, the optical module can synchronize with the external time, improving the versatility of the optical module's log recording. This allows the optical module's logs to be effectively used for operational data analysis, long-term reliability assurance, rapid problem delimitation, and early warning.

[0007] In conjunction with the first aspect, in some implementations of the first aspect, the first device is any one of wavelength division multiplexing board, optical switch or router.

[0008] In conjunction with the first aspect, in some implementations of the first aspect, the initial time of the first log is the first time. Therefore, the optical module can use precise time as a timeline to record logs and synchronize with the outside world. Furthermore, even without obtaining the first information, the optical module can still use its own timer to record logs.

[0009] In conjunction with the first aspect, in certain implementations of the first aspect, the first log includes at least one of the following information: optical power information, packet loss information, alarm information, temperature information, circuit information, monitoring information, configuration information, or fault location information. This allows for timely inspection and repair of the optical module using the information included in the first log, reducing potential network interruptions and performance degradation.

[0010] In conjunction with the first aspect, in some implementations of the first aspect, the optical module further includes a storage module, and the method further includes: a transceiver module receiving second information from a first device, the second information being used to request at least one second log, the second information including identification information indicating the type of at least one second log; a processing module determining a first storage partition in the storage module based on the identification information, and retrieving at least one second log from the first storage partition; and the transceiver module sending at least one second log to the first device. Thus, by classifying different logs recorded by the optical module and assigning identification information (e.g., ID) to different types of logs based on specific classifications, the log storage and upload process of the optical module is standardized, facilitating the first device to obtain logs of the same type in batches.

[0011] In conjunction with the first aspect, in some implementations of the first aspect, the type of at least one second log corresponds to the recording period and / or operation information of at least one second log. That is, the logging of the optical module can be configured with a recording period based on different application scenarios. And / or the log of the optical module can also be used to record the instruction information from the first device to the optical module and the corresponding operations performed by the optical module according to the instruction information.

[0012] In conjunction with the first aspect, in some implementations of the first aspect, the first storage partition belongs to the non-volatile memory within the storage module. Therefore, the log can be retained even after the optical module is powered off.

[0013] In conjunction with the first aspect, some implementations of the first aspect further include: the transceiver module receiving third information from the first device, the third information being used to request the acquisition of a third log; the transceiver module sending the third log to the first device, the initial time of the third log being zero. That is, even without obtaining the first information, the optical module can still use its own timer to record logs.

[0014] In conjunction with the first aspect, in certain implementations of the first aspect, wherein: the first information is a general management interface specification format; or the first information is a 100G packaged pluggable module multi-source protocol format, to facilitate batch acquisition and / or analysis of logs by the device.

[0015] Secondly, a monitoring method for an optical module is provided. This method can be executed by a first device. Unless otherwise specified, the "first device" in this application can refer to the first device itself, a component in the first device (e.g., a processor, chip, or chip system), or a logic module or software that can implement all or part of the functions of the first device.

By utilizing the parent device of the optical module to send the current time to the optical module, the optical module is synchronized with the external time, improving the versatility of the optical module's log recording. This allows the optical module's logs to be effectively used for operational data analysis, long-term reliability assurance, rapid problem delimitation, and early warning.

[0017] In conjunction with the second aspect, in some implementations of the second aspect, the first device is any one of wavelength division multiplexing board, optical switch or router.

[0018] In conjunction with the second aspect, in some implementations of the second aspect, the initial time of the first log is the first time. Therefore, the optical module can use precise time as a timeline to record logs and synchronize with the outside world. Furthermore, even without obtaining the first information, the optical module can still use its own timer to record logs.

[0019] In conjunction with the second aspect, in some implementations of the second aspect, the first log includes at least one of the following information: optical power information, packet loss information, alarm information, temperature information, circuit information, monitoring information, configuration information, or fault location information. This allows for timely inspection and repair of the optical module using the information included in the first log, reducing potential network interruptions and performance degradation.

[0020] In conjunction with the second aspect, some implementations of the second aspect further include: a first device sending second information to the optical module, the second information being used to request at least one second log, wherein the second information includes identification information indicating the type of the at least one second log; the first device receiving at least one second log from the optical module, wherein the at least one second log is retrieved by the optical module from a first storage partition, the first storage partition being determined by the optical module based on the identification information. Thus, by classifying different logs recorded by the optical module and assigning identification information (e.g., ID) to different types of logs based on specific classifications, the log storage and upload process of the optical module is standardized, facilitating the first device to obtain logs of the same type in batches.

[0021] In conjunction with the second aspect, in some implementations of the second aspect, at least one type of the second log corresponds to the recording period and / or operation information of the second log. That is, the logging of the optical module can be configured with a recording period based on different application scenarios. And / or the log of the optical module can also be used to record the instruction information from the first device to the optical module and the corresponding operations performed by the optical module based on the instruction information.

[0022] In conjunction with the second aspect, in some implementations of the second aspect, the first storage partition is a non-volatile memory within the optical module. Therefore, the log can be retained even after the optical module is powered off.

[0023] In conjunction with the second aspect, some implementations of the second aspect further include: the first device sending third information to the optical module, the third information indicating the format of the first log. Thus, the first device and the optical module can negotiate the log format, allowing the log to be directly read after it arrives at the first device, improving the universality and compatibility of the optical module's log recording.

[0024] In conjunction with the second aspect, some implementations of the second aspect further include: the first device sending third information to the optical module, the third information being used to request a third log; the first device receiving the third log from the optical module, the initial time of the third log being zero. That is, even without obtaining the first information, the optical module can still use its own timer to record logs.

[0025] In conjunction with the first aspect, in certain implementations of the first aspect, wherein: the first information is a general management interface specification format; or the first information is a 100G packaged pluggable module multi-source protocol format, to facilitate batch acquisition and / or analysis of logs by the device.

[0050] The technical solutions in this application will now be described with reference to the accompanying drawings.

[0051] With the growth of internet traffic and data volume, optical modules, as key components in optical communication that enable optical signal transmission and electrical signal conversion, have become increasingly important. The performance of optical modules directly affects the stability and efficiency of the entire communication system. Therefore, to ensure the operation of optical modules, intelligent monitoring and diagnosis, such as long-term operational data analysis, long-term reliability assurance, rapid problem identification, and early warning, have become a major focus of the optical communication industry. However, currently, optical modules often operate independently, logging data without connecting to other devices. When these logs are retrieved externally, accurate data analysis is difficult. Therefore, improving the universality of optical module logging is a pressing technical problem that needs to be solved.

[0052] In view of this, embodiments of this application provide a monitoring method for an optical module, an optical module, and an optical communication device to improve the versatility of the optical module's log recording.

[0053] Figure 1 is a schematic diagram of a monitoring method for an optical module provided in an embodiment of this application. As shown in Figure 1, this method is implemented through interaction between the optical module and a first device. The first device is the parent device of the optical module, and the optical module and the first device are connected through one or more interfaces. Alternatively, it can be understood that an optical module is inserted into the optical module of the first device. The first device can be any one of a wavelength division multiplexing (WDM) board, an optical switch, or a router. The WDM board is used in a wavelength division multiplexing (WDM) system for wavelength division multiplexing and / or demultiplexing optical signals. Specifically, the WDM board may include an optical transponder unit (OTU), an optical multiplexer unit (OMU), and an optical demultiplexer unit (ODU). The optical switch is used to switch the working path of the optical signal. The router is used for data transmission at the network layer. The optical module is used for the conversion between optical and electrical signals. The optical module may include a transmitting optical sub-assembly (TOSA) and / or a receiving optical sub-assembly (ROSA). Furthermore, the optical module includes a transceiver module, a processing module, and a log generation module. The transceiver module can exchange information with the first device.

[0054] As shown in Figure 1, the method includes steps S110-S130.

[0055] S110, the first device generates first information, which is used to indicate the first time determined by the first device.

[0056] In some implementations, the "first time determined by the first device" is a "standard time." In this case, the first device can be connected to a network or a network management device to determine the first information. In other implementations, the "first time determined by the first device" can be determined solely by the first device itself. In this case, the first information is only used for time synchronization between the first device and the optical module. Furthermore, the "first time determined by the first device" can also be called "standard time," "reference time," "absolute time," etc. "First information" can also be understood as a "timestamp," which is usually expressed in the form of date and time, and can be accurate to shorter time units such as seconds and milliseconds.

[0057] S120, the first device sends first information to the optical module; correspondingly, the transceiver module of the optical module receives the first information from the first device.

[0058] The first device and the optical module can each be equipped with a separate time interface, and the first information can be transmitted through the time interface.

[0059] S130, the optical module's processing module parses the first information to obtain the first time.

[0060] S140, the log generation module of the optical module records the first log based on the first information.

[0061] The optical module recording the first log based on the first information can also be understood as: the optical module uses the first information as the initial time of the log and begins recording the first log. Thus, the optical module can use precise time as a timeline to record the log and synchronize with the external environment. Furthermore, even without obtaining the first information, the optical module can still use its own timer to record the log.

[0062] In some implementations, the first log includes at least one of the following information: optical power information, packet loss information, alarm information, temperature information, circuit information, monitoring information, or fault location information. This allows for timely inspection and repair of the optical module using the information included in the first log, reducing potential network interruptions and performance degradation. Specifically, optical power information refers to the optical module's transmit power (TX power) and / or receive power (RX power). Packet loss information indicates data packet loss during transmission. Alarm information indicates abnormal conditions detected by the optical module, such as optical link disconnection, overheating, or power supply problems. Temperature information records the operating temperature of the optical module. Circuit information indicates the operating status of the internal circuitry of the optical module, such as power supply voltage, current, and signal integrity. Monitoring information records the optical module's monitoring of received and / or transmitted signal light. Fault location information specifically refers to fault diagnosis data, such as faults in specific circuits, fiber breaks, or connector defects. Configuration information indicates the optical module's configuration parameters and current status, such as wavelength, rate, and duplex mode.

[0063] In the method shown in Figure 1, the optical module synchronizes its time with the external time by using the parent device of the optical module to send the current time to the optical module. This improves the versatility of the optical module's log recording, making the optical module's logs effective for runtime data analysis, long-term reliability assurance, rapid problem delimitation, and early warning.

[0064] Figure 2 is a schematic diagram of another monitoring method for an optical module provided in an embodiment of this application. The method in Figure 2 is also applied to the interaction between the optical module and the first device. The specific details of the first device and the optical module have been described with reference to Figure 1, and will not be repeated here. In addition, the optical module also includes a storage module. As shown in Figure 2, the method includes steps S210-S230.

[0065] S210, the first device sends second information to the optical module; the transceiver module of the optical module receives the second information from the first device. The second information is used to request at least one second log. The second information includes identification information, which is used to indicate the type of at least one second log.

[0066] In some implementations, the type of at least one second log corresponds to the recording period of at least one second log.

[0067] Where at least one type of second log corresponds to at least one recording period of a second log, the logging of the optical module is set based on different application scenarios. For example, the logging period can be divided into ultra-short period logs, short period logs, long period logs, and ultra-long period logs. For example, ID 0x1 is an ultra-short period log, ID 0x2 is a short period log, and ID 0x3 is a long period log, etc. The specific recording periods of the above logs increase sequentially. Among them, the recording period of ultra-short period logs can be less than 5 minutes, for example, 1 to 3 minutes. The recording period of short period logs can be 10 minutes. The recording period of long period logs can be 1 hour. The recording period of ultra-long period logs can be 24 hours.

[0068] In some implementations, the log recording period can correspond to its storage period; the longer the log recording period, the longer its storage period in the optical module. That is, the storage period can decrease sequentially from the aforementioned ultra-long-period logs to the ultra-short-period logs. For example, the storage time of the aforementioned ultra-long-period logs in the optical module can be the same as the lifespan of the optical module, while the storage time of the aforementioned ultra-short-period logs in the optical module can be 24 hours. Since the optical module's logs are stored in different partitions according to log type, after storing multiple logs of the same type in a storage partition, log rotation can be performed, deleting the stored logs in chronological order and overwriting the storage space they occupy.

[0069] In some implementations, the type of log entry can correspond to the operation information. For example, the log can be used to record operation information instructed by the first device to the optical module. Alternatively, the log can also be used to record operation information performed by the optical module.

[0070] The logs with different recording periods mentioned above can be used for different application scenarios. For example, ultra-short-cycle logs, with their short recording period and large data volume, are used in production temperature-controlled processing scenarios. Short-cycle logs are used for anomaly localization in the production network. Long-cycle logs are used for production network operation trend analysis. Ultra-long-cycle logs, with their smaller data volume, are used for production network operation trend analysis. The logs with different recording periods mentioned above can include the same type of information or different types of information, depending on the actual situation. For example, logs with different recording periods mentioned above can all include performance information, temperature information, circuit information, voltage information, etc., of optical modules. It should be understood that the above naming method is only for convenience, and the specific log name corresponding to the type should be determined according to the actual situation.

[0071] S220, the optical module's processing module determines the first storage partition based on the identification information and retrieves at least one second log from the first storage partition.

[0072] In other words, the logs of the optical module are stored in different partitions of the storage module according to the log type, which makes it convenient for the optical module to retrieve and upload them.

[0073] In some implementations, the first storage partition is a non-volatile memory within the storage module. Therefore, the log can be retained even after the optical module is powered off.

[0074] In some implementations, the at least one second log is first recorded in volatile memory and then transferred to non-volatile memory. That is, the optical module periodically moves the log to non-volatile memory to prevent it from being cleared after the optical module is powered off. Furthermore, after the optical module retrieves at least one second log from the first storage partition, it can also pre-store the at least one second log in a designated area (e.g., a standard protocol area determined by the protocol between the optical module and the first device), so that the optical module can subsequently send the at least one second log to the first device via the protocol interface.

[0075] The non-volatile memory mentioned above can be a flash memory chip, and the volatile memory mentioned above can be random access memory (RAM).

[0076] S230, the transceiver module of the optical module sends at least one second log to the first device; correspondingly, the first device receives at least one second log from the optical module.

[0077] In the method shown in Figure 2, different logs recorded by the optical module are classified, and identification information (such as ID) is assigned to different types of logs based on the specific classification. This standardizes the log storage and upload process of the optical module, making it easier for the first device to obtain logs of the same type in batches.

[0078] Figure 3 is a schematic diagram of another optical module monitoring method provided in an embodiment of this application. The method in Figure 3 is also applied to the interaction between the optical module and the first device. The specific details of the first device and the optical module have been described with reference to Figure 1, and will not be repeated here. As shown in Figure 3, the method includes steps S310-S330.

[0079] S310, the first device sends third information to the optical module; the transceiver module of the optical module receives the third information from the first device, and the third information is used to request the third log.

[0080] S320, the first device receives the third log from the optical module; the transceiver module of the optical module sends the third log to the first device, and the initial time of the third log is zero.

[0081] In other words, even without obtaining the first information, the optical module can still use its own timer to record logs. In some implementations, the recording time of the third log is before the recording time of the first log, and the end time of the third log overlaps with the start time of the first log (the first information described in Figure 1). Therefore, after the first device obtains the third log, it can determine the specific recording time of the third log.

[0082] It should be understood that the methods described in Figures 1 to 3 can be combined, and the combined method should still fall within the protection scope of this application.

[0083] The following describes the complete process of monitoring optical modules, with reference to Figure 4.

[0084] Figure 4 is a schematic diagram of another monitoring method for an optical module provided in an embodiment of this application. The method in Figure 4 is also applied to the interaction between the optical module and the first device. The specific details of the first device and the optical module have been described with reference to Figures 1 to 3, and will not be repeated here.

[0085] As shown in Figure 4(a), the method may include steps S411-S417.

[0086] S411, the optical module is powered on, and the log generation module of the optical module starts the log recording function.

[0087] S412, the optical module's log generation module uses its own timer to record a third log.

[0088] S413, the first device sends first information to the optical module; correspondingly, the transceiver module of the optical module receives the first information from the first device, which indicates a first time determined by the first device.

[0089] S414, the log generation module of the optical module records the first log based on the first information.

[0090] S415, the first device sends fourth information to the optical module; correspondingly, the transceiver module of the optical module receives the fourth information from the first device, which is used to request the first log and the third log.

[0091] S416, the first device receives the first log and the third log from the optical module; correspondingly, the transceiver module of the optical module sends the first log and the third log to the first device.

[0092] S417, the first device calculates the actual corresponding time of the information in the third log based on the corresponding time in the first log.

[0093] As shown in Figure 4(b), the method may include steps S421-S427.

[0094] S421, the optical module is powered on, and the log generation module of the optical module starts the log recording function.

[0095] S422, the first device sends first information to the optical module; correspondingly, the transceiver module of the optical module receives the first information from the first device, which indicates a first time determined by the first device.

[0096] S423, the log generation module of the optical module records the first log based on the first information.

[0097] S424, the optical module stores the first log in the RAM of the storage module. Then, based on the type of the first log, it stores it in the first storage partition of the flash memory included in the storage module.

[0098] S425, the first device sends the sixth information to the optical module; correspondingly, the transceiver module of the optical module receives the fifth information from the first device, which is used to request the first log, and the fifth information also includes the identification information of the first log.

[0099] S426, the optical module's processing module determines the first storage partition based on the identification information of the first log, and retrieves the first log from the first storage partition.

[0100] S427, the transceiver module of the optical module sends the first log to the first device; correspondingly, the first device receives the first log from the optical module.

[0101] It should be understood that this application does not restrict the specific command format of the first, second, and third information involved in the interaction between the first device and the optical module. For example, the first, second, and third information can use the format specified by the Common Management Interface Specification (CMIS). CMIS can also be called the Order Interface Framework CMIS (OIF-CMIS). Its format can be the command data block (CDB) format.
