[0039] In order to enable those skilled in the art to better understand the technical solution of the present disclosure, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0040] It should be understood that the specific embodiments and drawings described herein are only used to explain the present disclosure rather than to limit the present disclosure.

[0044] It will be understood that, in the absence of conflict, the functions and steps marked in the flowcharts and block diagrams of the present disclosure may occur in an order different from that marked in the drawings.

[0045] It is understood that the flowcharts and block diagrams of the present disclosure illustrate the possible architectures, functions, and operations of the systems, devices, equipment, and methods according to the various embodiments of the present disclosure. Each box in the flowchart or block diagram may represent a module, unit, program segment, or code, which contains executable instructions for implementing the specified functions. Moreover, each box or combination of boxes in the block diagram and flowchart may be implemented by a hardware-based system that implements the specified functions, or may be implemented by a combination of hardware and computer instructions.

[0046] It can be understood that the modules and units involved in the embodiments of the present disclosure can be implemented by software or hardware, for example, the modules and units can be located in a processor.

[0047] In order to facilitate the understanding of the present disclosure, the main inventive concept of the present disclosure is first introduced below.

[0048] Operators' switches, routers, IPRAN, 4G / 5G base stations, OTN, WDN and other communication equipment use a large number of optical modules as communication equipment. These devices serve as business cores, aggregation and access and carry a large number of services. If an optical module fails, it may affect a large area of ​​business.

[0049] When repairing network faults, the existing technology makes cross-disciplinary processing very difficult, and it is difficult to handle faults at a small granular level (locating each specific optical module). Although each manufacturer's network management will issue an alarm when an optical module fault occurs, there is no prediction function. The optical module fault can only be handled after the fault occurs. According to the different core, aggregation, and access network levels, it is inevitable to check from top to bottom or from bottom to top to locate the faulty optical module.

[0050] During the use of optical modules, various problems are inevitable. When connecting optical modules to optical modules through optical fibers, the optical port light may not be on, the optical port light is red, or there may be alarms or optical module failures. In the daily use of optical modules, internal faults such as poor optical power, poor eye diagram, poor receiving end, poor working current, and program programming failure may be encountered. Poor eye diagrams of optical modules generally include poor extinction rate, scattered eye diagrams, irregular patterns, or no eye diagrams.

[0051] The existing technology can troubleshoot optical module failures by inspecting the appearance of the optical module to see if there is obvious damage to the optical module, or by using some tools to compare the optical module with a good one. The existing methods generally use instrument eye diagrams or physical observation of the appearance. The existing business requires unplugging the optical module for testing, which not only affects the business, but also has a large number of existing networks. Based on this method, it is not realistic and cannot implement a program-based inference algorithm.

[0052] The present invention aims to identify and determine the degradation of the optical module of the communication equipment, calculate the degraded optical module through programmed calculation, and replace the optical module by cutting over at night when no fault occurs, so as not to affect the existing network services and solve the network hidden dangers.

[0053] The performance degradation of optical modules refers to the pre-emptive processing before the optical modules fail. The extinction ratio is a calculation formula for the degradation of optical modules, but the performance cannot be collected in the equipment. External instruments are required to observe the optical modules for a long time to obtain the extinction ratio. The network equipment operates normally, and this method cannot solve the demand problem. This disclosure is based on big data calculation, using long-term collection data to perform year-on-year and month-on-month deduction calculation and analysis.

[0054] An optical module is equipped with a laser (activator). The laser serves as the light source of the optical module. The measurement of the operating efficiency of the laser is used as the basis for judging the degradation of the optical module, which has been proven by the method. Under full modulation conditions, the optical power, temperature, voltage, current and activator performance of the optical module of the optical transmission signal remain consistent. These parameters can be used to judge the activator (transmitter) failure. Based on this, the present disclosure can also locate whether the optical module has a transmitter failure or a receiver failure. There is no need to separately convert the optical bias state and the available laser transmission power into the physical quantity of modulation power. Modulation power refers to the energy conversion efficiency between the signal and the carrier in the communication system.

[0055] The present disclosure also determines whether it is an internal problem of the optical module itself or a fault caused by improper external use. The internal problem is natural aging during operation, and the external problem includes human damage, environmental factors, etc.

[0056] Embodiment 1:

[0057] like Figure 1 As shown, the present disclosure provides a method for determining degradation of an optical module, the method comprising:

[0058] S1. Acquire the performance parameters of the optical module under full modulation conditions in a collection cycle;

[0059] S2. Obtaining a month-on-month change of the performance parameter in at least one calculation cycle;

[0060] S3, obtaining a year-on-year change of the performance parameter in at least one year-on-year total period using the at least one calculation period;

[0061] S4. Determine whether the optical module is degraded and the cause of the degradation according to the month-on-month change and the year-on-year change.

[0062] In this embodiment, the method collects the performance parameters of the optical module under full modulation conditions and obtains the month-on-month and year-on-year changes in the performance parameters to determine the degradation of the optical module and the cause of the degradation. It can identify the degradation of the optical module in a timely manner to eliminate the hidden dangers of network failures, and by obtaining the cause of the degradation, it can help find an effective method to solve the degradation problem.

[0063] Specifically, in order to solve the hidden dangers of network failures, this embodiment proposes the idea of ​​active maintenance, which is a method based on AI (Artificial Intelligence) to judge the degradation of optical modules. In the experimental environment of big data, by studying the prediction and judgment of optical module degradation, the month-on-month and year-on-year changes of performance parameters are introduced as the basis for judging the performance degradation of optical modules. The month-on-month changes mainly reflect the sudden performance changes, and the year-on-year changes mainly reflect the cumulative performance changes. Therefore, the two can help find the cause of the degradation, solve the occurrence of failures that have not occurred, maintain the normal operation of the operator's business, reduce the complaint rate, and improve user perception.

[0064] In one implementation, S1, acquiring performance parameters of the optical module under full modulation conditions in a collection period, specifically includes:

[0065] Five minutes is used as a collection cycle, and the performance parameters of the optical module under full modulation conditions are collected once in each collection cycle. The performance parameters at least include operating voltage, operating temperature, operating current and luminous optical power.

[0066] In this embodiment, the acquisition of optical module performance mainly includes: the operator's network equipment, usually using the equipment's command line (CLI, Command Line Interface, the operation mode provided by the network equipment to remote management personnel), SNMP (Simple Network Management Protocol, Simple Network Management Protocol) communication protocol, Tr069 communication protocol (the communication protocol between CPE and ACS, CPE can use this protocol to complete service activation, function setting, file upload and download, system detection, etc., which are necessary actions for initialization and operation management) to obtain equipment performance. The optical module performance is one of the performance of the equipment. The voltage, current, power, light emitting power, light receiving power, and temperature of the optical module can be obtained. Under full modulation conditions, the performance of the optical module can be collected at a granularity of five minutes. Table 1 shows an example of the collected optical module performance parameters.

[0067] Table 1 Examples of collected optical module performance parameters

[0068] date Time granularity Voltage Current mA Power mW Temperature ℃ Transmitted optical power dBm Received optical power dBm November 29 11:00 3.244 32.58 105.69 32.275 -2.349 -2.337 November 29 11:15 3.245 32.579 105.72 32.275 -2.35 -2.337 November 29 11:30 3.244 32.58 105.69 32.275 -2.35 -2.338 November 29 11:45 3.245 32.581 105.73 32.275 -2.349 -2.337 November 29 12:00 3.244 32.58 105.69 32.275 -2.349 -2.338 November 29 12:15 3.244 32.58 105.69 32.275 -2.349 -2.338 November 29 12:30 3.245 32.579 105.72 32.275 -2.35 -2.338 November 29 12:45 3.244 32.58 105.69 32.275 -2.349 -2.338 November 29 13:00 3.244 32.581 105.69 32.275 -2.349 -2.337 November 29 13:15 3.244 32.58 105.69 32.275 -2.349 -2.337 November 29 13:30 3.245 32.58 105.72 32.275 -2.35 -2.337

[0069] In one implementation, the performance parameters further include operating power and received optical power, and the operating power is directly collected or obtained by multiplying the operating voltage by the operating temperature.

[0070] In this embodiment, the emitting optical power is the optical signal converted from the electrical signal through the optoelectronic module after the optical module receives the electrical signal. The receiving optical power reflects the fault of the receiving end. Some manufacturers can collect power. If the manufacturer does not support it, the voltage and current can be collected uniformly and can be calculated by yourself. Current*voltage equals power.

[0071] In one embodiment, after S4, judging whether the optical module is degraded and the cause of the degradation according to the month-on-month change and the year-on-year change, the method further includes:

[0072] In response to the optical module degradation being determined based on a change in the operating voltage, an increase in the operating temperature, or a synchronous increase in the operating current and the luminous optical power, determining that the optical module is degraded at the transmitting end;

[0073] In response to the fact that the degradation of the optical module is determined based on a change in the operating power or the received optical power, it is determined that the optical module is degraded at the receiving end.

[0074] In this embodiment, under the condition of full modulation, the optical power (transmitted optical power), temperature, voltage, current and activator performance of the optical module of the optical transmission signal are consistent. By judging the light source (laser) of the optical module, it is judged whether the optical module transmitting end fault or receiving end fault is faulty. For example, the following judgments are made in sequence. If the voltage changes on a month-on-month basis, either upward or downward, it can be judged that the optical module laser is abnormal (degraded); if the voltage remains unchanged and the temperature changes abnormally, such as a month-on-month increase in temperature, it can be preliminarily judged that the optical module laser is abnormal; if the voltage and temperature remain unchanged, or the month-on-month increase is not large, and the current and the emitting optical power increase synchronously on a month-on-month basis, it can be preliminarily judged that the optical module laser is abnormal. After the above judgment, if the laser is normal, but the change in the working power or the receiving optical power is abnormal, it is judged that the receiving end of the optical module is degraded.

[0075] In one implementation, S2, obtaining a month-on-month change of the performance parameter in at least one calculation cycle, specifically includes:

[0076] At least one of the collection period, hour, day, week, month, and year is used as the calculation period.

[0077] Obtain at least one of the collected values ​​of each collection period, the hourly average value, the daily average value, the weekly average value, the monthly average value and the annual average value of the performance parameter,

[0078] Calculate the month-on-month change rate of at least one of the current collection period collection value and the previous collection period collection value, the current hourly average value and the previous hourly average value, the current day average value and the yesterday average value, the current week average value and the last week average value, the current month average value and the last month average value, and the current year average value and the last year average value.

[0079] In this embodiment, the month-on-month changes are divided into different month-on-month calculation periods, including five minutes, one hour, daily month-on-month, weekly month-on-month, monthly month-on-month and annual month-on-month, etc.; the current month-on-month growth (decline) rate calculation formula is: current performance month-on-month growth (decline) rate (%) = [(current performance / previous performance)-1]*100%; if the calculated value is positive (+), it is called the growth rate; if the calculated value is negative (-), it is called the decline rate; if the current period refers to the current day, week, month and year, etc., then the previous period refers to yesterday, last week, last month and last year, etc.

[0080] In one embodiment, obtaining the year-on-year change of the performance parameter in at least one year-on-year total period using the at least one calculation cycle specifically includes:

[0081] Take at least one of the hours, days, weeks, months, years, or multiple years as the year-on-year total period.

[0082] Calculate the year-on-year change rate between the collection value of the current collection period and the collection value of the same collection period of at least one of the previous hour, day, week, month, year, or multiple years, the current hourly average value and the average value of the same hour of at least one of the previous day, week, month, year, or multiple years, the current day's average value and the average value of the same day of at least one of the previous week, month, year, or multiple years, the current week's average value and the average value of the same week of at least one of the previous month, year, or multiple years, the current month's average value and the average value of the same month of at least one of the previous year or multiple years, and the current year's average value and at least one of the average values ​​of the same year of the previous multiple years.

[0083] In this embodiment, the year-on-year change adopts the same calculation period as the month-on-month change, and different year-on-year total periods are adopted, including one-hour year-on-year, daily year-on-year, weekly year-on-year, monthly year-on-year, annual year-on-year and multi-year year-on-year, etc.; taking year as the year-on-year total period as an example, the calculation formula for the current performance year-on-year growth (decrease) rate is: Current performance year-on-year growth (decrease) rate (%) = [(current performance / performance in the same period of the previous year) - 1] * 100%; if the calculated value is positive (+), it is called the growth rate; if the calculated value is negative (-), it is called the decline rate; if the current period refers to the current day, week, month, etc., then the same period of the previous year refers to the same day, week, and month of the previous year, etc.

[0084] In one implementation, judging whether the optical module is degraded and the cause of the degradation according to the month-on-month change and the year-on-year change specifically includes:

[0085] In response to the month-on-month change exceeding a corresponding month-on-month change threshold, determining that the optical module is degraded and the cause of the degradation is external damage;

[0086] In response to the month-on-month change not exceeding the corresponding month-on-month change threshold and the year-on-year change exceeding the corresponding year-on-year change threshold, it is determined that the optical module is degraded and the cause of the degradation is aging of the optical module.

[0087] In this embodiment, the difference between the year-on-year change rate and the month-on-month change rate is: taking the growth rate as an example, the year-on-year growth rate means the growth rate, but another way of growth rate, when calculating the year-on-year growth rate, there is a specific time limit. Under the premise of the month-on-month growth rate being stable, if the year-on-year growth rate exceeds a certain threshold, it means that the performance degradation is gradually accumulated, so it can be judged as the aging of the optical module. On the contrary, if the month-on-month change exceeds the threshold, it means that the change occurs relatively quickly, and it is more likely to be an external fault, such as man-made damage, rain, etc. The device sampling values ​​such as voltage, current, temperature, and luminous value can be sampled through conventional calculation formulas and turned into charts to intuitively judge performance degradation.

[0088] In one embodiment, before judging whether the optical module is degraded and the cause of the degradation according to the month-on-month change and the year-on-year change, the method specifically includes:

[0089] There is more than one calculation cycle, and different month-on-month change thresholds are set according to different calculation cycles. The different month-on-month change thresholds are used to assist in determining the specific form of the external damage;

[0090] There is more than one year-on-year total cycle, and different year-on-year change thresholds are set according to different calculation cycles and year-on-year total cycles. Different year-on-year change thresholds are used to assist in determining specific parts of the optical module that are aged.

[0091] In this embodiment, the year-on-year ratio is divided into period-on-year ratio, hour-on-year ratio, day-on-year ratio, week-on-year ratio, month-on-year ratio and year-on-year ratio, etc., and the specific forms of external damage can be further analyzed based on this. For example, human damage is usually very fast and will cause obvious performance degradation within five minutes or an hour. Rainfall is divided into direct damage to the optical module or causing the environment in which the optical module is located to be humid. A humid environment will cause the performance of the optical module to gradually deteriorate. For example, continuous rainfall for a week will cause the performance of the optical module to continue to gradually deteriorate. Similarly, the aging of the optical module will also have different characteristics of aging cycles caused by different parts. The relationship between the specific forms of external damage and optical module aging and the year-on-year cycle can be established through subsequent continuous observation and statistics, and this idea is provided here.
