Description

Technical Field

[0001] This invention relates to the field of communication technology, and in particular to a method, apparatus, computer equipment, and storage medium for controlling optical power. Background Technology

[0002] Passive Optical Network (PON) is a primary technology commonly used by operators in the field of fiber optic broadband access. A PON consists of an Optical Line Terminal (OLT), an Optical Distribution Network (ODN), and user-end equipment. User-end equipment includes Optical Network Terminals (ONTs) and Optical Network Units (ONUs). An ONT is typically used by a single user and is commonly referred to as an optical modem. User terminals using Fiber to the Office (FTTO) or Fiber to the Home (FTTH) are ONTs. An ONU, on the other hand, is usually shared by multiple users and is mainly used in Fiber to the Building (FTTB).

[0003] ONU weak light refers to the phenomenon where the optical power received by the ONU is less than the ONU's receiving sensitivity. ONU receiving sensitivity refers to the minimum optical power that the ONU can receive when it is working normally. Typically, the ONU receiving sensitivity specification for home broadband is -27.0dBm. Therefore, a situation where the received optical power (or optical attenuation) of the ONU is lower than -27.0dBm is generally defined as ONU weak light.

[0004] Currently, low optical power consumption by ONUs is very common, with some operators experiencing a low optical power rate (the percentage of ONUs with received optical power below -27.0dBm) exceeding 4.5%. Such a high rate negatively impacts users' internet experience. Low optical power from ONUs severely affects broadband service quality, making ensuring that ONU received optical power meets standards a crucial task for operators aiming to improve user experience. Summary of the Invention

[0005] The technical problem to be solved by this invention is that the low light rate of the operator's ONU in the prior art has a high rate of negative impact on the user's Internet experience.

[0006] To address the aforementioned shortcomings of existing technologies, the following solutions are provided:

[0007] In a first aspect, the present invention provides a method for controlling received optical power, comprising: obtaining a range of a threshold for a weak optical limit of a PON port based on a target value and a minimum value of a weak optical limit of a PON port; obtaining the minimum received optical power of all ONUs of a first PON port in a first period, and determining a threshold for a weak optical limit of the first PON port in a second period based on the range of the minimum received optical power of all ONUs of the first PON port in the first period and the threshold for a weak optical limit of the PON port; and, in the second period, real-time detecting the received optical power of a first ONU of the first PON port; monitoring the first ONU if the received optical power of the first ONU of the first PON port is lower than the threshold for a weak optical limit of the first PON port in the second period; and performing a shutdown operation on the first ONU if the received optical power of the first ONU when it goes offline and comes back online in the second period is lower than the threshold for a weak optical limit of the first PON port in the second period. Wherein, the first PON port is any PON port, and the first ONU is any one of all ONUs of the first PON port.

[0008] Optionally, obtaining the range of the PON port's weak light limitation threshold based on the target value and the minimum value of the PON port's weak light limitation includes: obtaining the target value and the minimum value of the PON port's weak light limitation, respectively. Furthermore, determining a first set based on the target value and the minimum value of the PON port's weak light limitation, and using the first set as the range of the PON port's weak light limitation threshold. The first set includes the target value of the PON port's weak light limitation, the minimum value of the PON port's weak light limitation, and at least one value between the target value and the minimum value of the PON port's weak light limitation.

[0009] Optionally, the minimum received optical power of all ONUs of the first PON port in the first cycle is obtained, and the weak light limitation threshold of the first PON port in the second cycle is determined based on the range of the minimum received optical power of all ONUs of the first PON port in the first cycle and the weak light limitation threshold of the PON port. This includes: collecting the received optical power of all ONUs of the first PON port in the first cycle and obtaining the minimum received optical power of all ONUs of the first PON port in the first cycle; and comparing the minimum received optical power of all ONUs of the first PON port in the first cycle with the range of the weak light limitation threshold of the PON port to determine the weak light limitation threshold of the first PON port in the second cycle, wherein the range of the weak light limitation threshold of the PON port includes multiple values.

[0010] Optionally, in response to the minimum value within the range where the minimum received optical power of all ONUs of the first PON port in the first cycle is less than the minimum value of the weak light limiting threshold of the PON port, the minimum value within the range of the weak light limiting threshold of the PON port is determined as the weak light limiting threshold of the first PON port in the second cycle. In response to the minimum received optical power of all ONUs of the first PON port in the first cycle being between the maximum and minimum values ​​within the range of the weak light limiting threshold of the PON port, and the range of the weak light limiting threshold of the PON port including only one integer with the smallest difference from the minimum received optical power of all ONUs of the first PON port in the first cycle, the integer with the smallest difference from the minimum received optical power of all ONUs of the first PON port in the first cycle is determined as the weak light limiting threshold of the first PON port in the second cycle. In response to the minimum received optical power of all ONUs of the first PON port in the first cycle being between the maximum and minimum values ​​within the range of the weak light limiting threshold of the PON port, and the range of the weak light limiting threshold of the PON port including two integers with the smallest difference between the minimum received optical power of all ONUs of the first PON port in the first cycle, the larger of the two integers with the smallest difference between the minimum received optical power of all ONUs of the first PON port in the first cycle included in the range of the weak light limiting threshold of the PON port is determined as the weak light limiting threshold of the first PON port in the second cycle.

[0011] Secondly, the present invention provides a received light power control device, comprising: a threshold range acquisition module, a threshold determination module, and a rectification control module. The threshold range acquisition module is configured to: acquire the range of the weak light limit threshold of the PON port based on the target value and the minimum value of the weak light limit of the PON port. The threshold determination module is configured to: acquire the minimum received light power of all ONUs of the first PON port in a first cycle, and determine the weak light limit threshold of the first PON port in a second cycle based on the range of the minimum received light power of all ONUs of the first PON port in the first cycle and the weak light limit threshold of the PON port. The rectification control module is configured to: detect the received light power of the first ONU of the first PON port in real time during the second cycle; monitor the first ONU if the received light power of the first ONU of the first PON port is lower than the weak light limit threshold of the first PON port in the second cycle; and perform a shutdown operation on the first ONU if the received light power of the first ONU when it goes offline and comes back online in the second cycle is lower than the weak light limit threshold of the first PON port in the second cycle. Wherein, the first PON port is any PON port, and the first ONU is any ONU among all ONUs of the first PON port.

[0012] Optionally, the threshold range acquisition module includes a target value and minimum value acquisition unit and a threshold range acquisition unit. The target value and minimum value acquisition unit is configured to acquire, respectively, the target value and the minimum value of the weak light limit for the PON port. The threshold range acquisition unit is configured to determine a first set based on the target value and the minimum value of the weak light limit for the PON port, and use this first set as the range of the threshold for the weak light limit of the PON port. The first set includes the target value of the weak light limit for the PON port, the minimum value of the weak light limit for the PON port, and at least one value between the target value and the minimum value of the weak light limit for the PON port.

[0013] Optionally, the threshold determination module includes a minimum received optical power acquisition unit and a threshold determination unit. The minimum received optical power acquisition unit is configured to: acquire the received optical power of all ONUs of the first PON port within the first cycle, and acquire the minimum received optical power of all ONUs of the first PON port within the first cycle. The threshold determination unit is configured to: compare the minimum received optical power of all ONUs of the first PON port within the first cycle with the range of the weak light limitation threshold of the PON port to determine the weak light limitation threshold of the first PON port within the second cycle, wherein the range of the weak light limitation threshold of the PON port includes multiple values.

[0014] Optionally, the threshold determination unit is configured as follows: In response to the minimum value within the range where the minimum received optical power of all ONUs of the first PON port in the first cycle is less than the threshold of the weak light limitation of the PON port, the minimum value within the range of the weak light limitation threshold of the PON port is determined as the threshold of the weak light limitation of the first PON port in the second cycle. In response to the minimum received optical power of all ONUs of the first PON port in the first cycle being between the maximum and minimum values ​​within the range of the weak light limitation threshold of the PON port, and the range of the weak light limitation threshold of the PON port including only one integer with the smallest difference from the minimum received optical power of all ONUs of the first PON port in the first cycle, the integer with the smallest difference from the minimum received optical power of all ONUs of the first PON port in the first cycle is determined as the threshold of the weak light limitation of the first PON port in the second cycle. In response to the minimum received optical power of all ONUs of the first PON port in the first cycle being between the maximum and minimum values ​​within the range of the weak light limiting threshold of the PON port, and the range of the weak light limiting threshold of the PON port including two integers with the smallest difference between the minimum received optical power of all ONUs of the first PON port in the first cycle, the larger of the two integers with the smallest difference between the minimum received optical power of all ONUs of the first PON port in the first cycle included in the range of the weak light limiting threshold of the PON port is determined as the weak light limiting threshold of the first PON port in the second cycle.

[0015] Thirdly, the present invention provides a computer device, including a memory and a processor, wherein the memory stores a computer program, and when the processor runs the computer program stored in the memory, the processor executes the above-described optical power control method.

[0016] Fourthly, the present invention provides a computer-readable storage medium having a computer program stored thereon, wherein when the computer program is executed by a processor, the processor executes the above-described optical power control method.

[0017] The optical power control method, apparatus, computer equipment, and storage medium provided by this invention will not affect currently online ONUs, even if the current ONU is in a low-light state. It will also avoid the problem of PON port low-light configuration rollback due to a lack of rectification conditions in the short term. Within each statistical period, the number of ONU ports requiring rectification will not be high, allowing for more rational scheduling of rectification work and improved efficiency. Furthermore, the minimum optical power of the PON port will not fall below the low-light limit threshold of the previous statistical period in the next statistical period. Thus, with continuous rectification support, this periodic operation can continuously improve the overall low-light limit threshold of the PON ports, ultimately achieving the target value of -26dBm for the entire network. Therefore, this invention can ensure that the optical power received by ONUs meets the standards, improve broadband service quality, reduce the low-light rate, and enhance the user's internet experience.

[0025] To enable those skilled in the art to better understand the technical solution of the present invention, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0026] It is understood that the specific embodiments and accompanying drawings described herein are merely for explaining the invention and are not intended to limit the invention.

[0027] It is understood that, without conflict, the various embodiments and features in the embodiments of the present invention can be combined with each other.

[0028] It is understood that, for ease of description, only the parts related to the present invention are shown in the accompanying drawings, while the parts unrelated to the present invention are not shown in the drawings.

[0029] It is understood that each unit or module involved in the embodiments of the present invention may correspond to only one entity structure, or may be composed of multiple entity structures, or multiple units or modules may be integrated into one entity structure.

[0030] It is understood that, without conflict, the functions and steps marked in the flowcharts and block diagrams of this invention may occur in a different order than that marked in the accompanying drawings.

[0031] It is understood that the flowcharts and block diagrams of this invention illustrate the possible architecture, functions, and operations of systems, apparatuses, devices, and methods according to various embodiments of this invention. Each block in the flowchart or block diagram may represent a unit, module, program segment, or code, containing executable instructions for implementing the specified function. Furthermore, each block or combination of blocks in the block diagram and flowchart can be implemented using a hardware-based system to achieve the specified function, or using a combination of hardware and computer instructions.

[0032] It is understood that the units and modules involved in the embodiments of the present invention can be implemented by software or by hardware. For example, the units and modules can be located in a processor.

[0033] In related technologies, the optical attenuation anomaly handling process adopted by operators is as follows:

[0034] 1. The provincial company collects the received optical power of all users' online ONUs once a day;

[0035] 2. On a monthly basis, select ONU low-light users by city (e.g., users whose ONU light decay is <-26.0dBm);

[0036] 3. Issue the list of users with low light conditions to the prefecture-level cities for rectification;

[0037] 4. Monthly statistics on the rate of non-compliance with light decay standards and the completion rate of rectification are compiled by prefecture-level city to identify the prefecture-level cities that fail to meet the standards.

[0038] Among them, the light decay failure rate is the ratio of the total number of low-light users in the current month to the total number of users collected in the current month, and the rectification completion rate is the ratio of the number of rectifications completed in the current month to the total number of low-light users in the previous month.

[0039] Because some users' optical power is only slightly below normal, the difference in internet connectivity is not noticeable. These users often refuse to cooperate with on-site rectification, making rectification impossible and extremely difficult. However, ONU optical power naturally decreases unidirectionally due to line aging and environmental degradation, and this degradation is generally irreversible. Optical power is collected by the provincial company, and rectification is then scheduled at each level. Coordination and management at each stage are very difficult, relying heavily on manual labor. Furthermore, the time span from the onset of weak light to completion of rectification is generally 1-2 months. Therefore, the optical power anomaly handling solution in related technologies is a long-term, extremely resource-intensive, and highly demanding management task.

[0040] Some embodiments of the present invention provide a method for controlling received optical power, such as... Figure 1 As shown, the optical power control method may include steps 101 to 103.

[0041] Step 101. Obtain the range of the threshold for the weak light limit of the PON port based on the target value and the minimum value of the weak light limit of the PON port.

[0042] Understandably, PON low light limitation is a PON port configuration function. By setting a minimum acceptable optical power (e.g., -26dBm) on the PON port, if the received optical power of the ONU requesting to go online is less than the minimum acceptable optical power of the PON port, the PON port will not allow the ONU to go online (this function does not detect previously online ONUs).

[0043] Understandably, the target value of the PON port's weak light limitation can be the highest value in the range of the PON port's weak light limitation threshold, and the lowest value of the PON port's weak light limitation can be the lowest value in the range of the PON port's weak light limitation threshold. Thus, the range of the PON port's weak light limitation threshold can be obtained based on the target value and the lowest value of the PON port's weak light limitation.

[0044] In some embodiments, such as Figure 2 As shown, step 101 may include steps 1011 to 1012.

[0045] Step 1011. Obtain the target value and the minimum value of the weak light limit of the PON port respectively.

[0046] Understandably, the target value for the low light limit of the PON port refers to the target value for the received light power of the PON port, and the minimum value for the low light limit of the PON port refers to the minimum value for the received light power of the PON port.

[0047] For example, the target value for the low-light limitation of a PON port can be -26 dBm. If the received light power of the PON port is higher than -26 dBm, the PON port does not need to be modified. The minimum value for the low-light limitation of a PON port can be -33 dBm, which makes it almost unusable if the received light power of the user ONU is lower than -33 dBm.

[0048] Step 1012. Determine the first set based on the target value and the minimum value of the weak light limit of the PON port, and use the first set as the range of the threshold for the weak light limit of the PON port.

[0049] In step 1012, the first set includes the target value of the weak light limit of the PON port, the minimum value of the weak light limit of the PON port, and at least one value between the target value of the weak light limit of the PON port and the minimum value of the weak light limit of the PON port.

[0050] Understandably, the maximum value of the first set is the target value of the low light limit of the PON port, the minimum value of the first set is the lowest value of the low light limit of the PON port, and the first set also includes at least one value between the lowest value of the low light limit of the PON port and the target value of the low light limit of the PON port.

[0051] Understandably, the first set includes either the target value or the minimum value of the weak light limit for the PON port, which can be either integers or not. At least one value in the first set, ranging from the minimum value to the target value of the weak light limit for the PON port, can be either an integer or not. The following embodiment uses the example where all values ​​in the first set are integers, meaning that all values ​​within the range of the weak light limit threshold for the PON port are integers.

[0052] For example, if the target value of the weak light limit of the PON port is -26 dBm and the minimum value of the weak light limit of the PON port is -33 dBm, the first set may include -33, -26 and at least one integer from -33 to -26. For example, the first set may be {-33, -30, -26}, or the first set may be {-33, -30, -28, -26}, or the first set may also be {-33, -31, -30, -28, -26}.

[0053] In some embodiments, the first set includes a target value for the low light limit of the PON port and a minimum value for the low light limit of the PON port, as well as every integer between the minimum value for the low light limit of the PON port and the target value for the low light limit of the PON port.

[0054] Understandably, since different PON ports have different usage scenarios and different light attenuation conditions, it is convenient to apply the received light power control scheme provided by the embodiments of the present invention to different PON ports. The first set may include the target value of the weak light limit of the PON port and the minimum value of the weak light limit of the PON port, as well as every integer between the minimum value of the weak light limit of the PON port and the target value of the weak light limit of the PON port.

[0055] For example, if the target value for the low-light limitation of the PON port is -26 dBm and the minimum value for the low-light limitation of the PON port is -33 dBm, then the first set can be {-33, -32, -31, -30, -29, -28, -27, -26}.

[0056] Step 102. Obtain the minimum received optical power of all ONUs of the first PON port in the first cycle, and determine the threshold of the weak light limitation of the first PON port in the second cycle based on the minimum received optical power of all ONUs of the first PON port in the first cycle and the range of the weak light limitation threshold of the PON port.

[0057] In step 102, the first PON port can be any PON port.

[0058] Understandably, once the range of the low-light limiting threshold for the PON port is determined, different low-light limiting thresholds can be set for each PON port based on its specific characteristics. In step 102, the low-light limiting threshold for the first PON port in the second period is determined based on the minimum received light power of all ONUs of the first PON port in the first period and the range of the low-light limiting threshold for the PON port; that is, the low-light limiting threshold is set for the first PON port based on its specific characteristics.

[0059] Understandably, the lengths of the first and second cycles can be the same or different, depending on the local PON port optical attenuation conditions or the actual application scenario. For example, if the rectification workload is determined to be large based on the local PON port optical attenuation conditions, the lengths of the first and second cycles can be set to the same, such as one week or one month. If the rectification workload is determined to be small based on the local PON port optical attenuation conditions, the lengths of the first and second cycles can be set to two months to reduce the rectification workload.

[0060] In some embodiments, such as Figure 3As shown, the implementation method of step 102 may include steps 1021 to 1022.

[0061] Step 1021. Collect the received optical power of all ONUs of the first PON port in the first cycle, and obtain the minimum received optical power of all ONUs of the first PON port in the first cycle.

[0062] Step 1022. Compare the minimum received power of all ONUs of the first PON port in the first cycle with the range of the weak light limit threshold of the PON port to determine the weak light limit threshold of the first PON port in the second cycle.

[0063] In step 1022, the threshold range for the weak light limitation of the PON port includes multiple values.

[0064] In some embodiments, in response to the minimum value of the range of minimum received optical power of all ONUs of the first PON port in the first cycle being less than the minimum value of the weak light limit threshold of the PON port, the minimum value of the range of weak light limit threshold of the PON port is determined to be the weak light limit threshold of the first PON port in the second cycle.

[0065] Understandably, when any value in the first set is an integer, in response to the fact that the minimum received optical power of all ONUs of the first PON port in the first period after rounding down is less than the minimum value in the first set, the minimum value in the first set is determined to be the threshold for weak light limitation of the first PON port in the second period.

[0066] Understandably, the minimum received optical power of all ONUs of the first PON port in the first period may not be an integer. However, if all values ​​in the first set are integers, that is, if all values ​​in the range of the weak light limit threshold of the PON port are integers, then the minimum received optical power of all ONUs of the first PON port in the first period can be rounded down to determine the weak light limit threshold of the first PON port in the second period.

[0067] Understandably, if the minimum received optical power of all ONUs of the first PON port in the first period, after rounding down, is less than the minimum value in the first set, then the minimum value in the first set can be directly determined as the threshold for the weak light limitation of the first PON port in the second period. The minimum value in the first set is the lowest value of the weak light limitation of the PON port. Therefore, the threshold for the weak light limitation of the first PON port in the second period is the lowest value of the weak light limitation of the PON port.

[0068] Understandably, since the threshold for weak light limitation of the first PON port in the second cycle is determined based on the minimum value of each ONU in the first cycle, the number of ONUs with weak light limitation of the first PON port in the second cycle is limited. Therefore, if ONUs with received light power lower than the current threshold are taken offline for repair, the number of users reporting for repair can be kept within a controllable range.

[0069] In some embodiments, in response to the minimum received optical power of all ONUs of the first PON port in the first cycle being between the maximum and minimum values ​​in the range of the weak light limit threshold of the PON port, and the range of the weak light limit threshold of the PON port including only one integer with the smallest difference from the minimum received optical power of all ONUs of the first PON port in the first cycle, the integer with the smallest difference from the minimum received optical power of all ONUs of the first PON port in the first cycle in the range of the weak light limit threshold of the PON port is determined as the weak light limit threshold of the first PON port in the second cycle.

[0070] Understandably, when any value in the first set is an integer, in response to the minimum received optical power of all ONUs of the first PON port in the first period after rounding down being between the maximum and minimum values ​​in the first set, the integer with the smallest difference between the minimum received optical power of all ONUs of the first PON port in the first set and the minimum received optical power of all ONUs of the first PON port in the first period after rounding down is determined as the threshold for weak light limitation of the first PON port in the second period.

[0071] For example, when the first set is {-33, -30, -26}, the minimum received optical power of all ONUs of the first PON port in the first period after rounding down is -29. That is, the minimum received optical power of all ONUs of the first PON port in the first period after rounding down is between the maximum value and the minimum value in the first set. Since -30 is the integer with the smallest difference between the minimum received optical power of all ONUs of the first PON port in the first period and the minimum received optical power of all ONUs of the first PON port after rounding down, it can be determined that -30 is the threshold for weak light limitation of the first PON port in the second period.

[0072] In some embodiments, in response to the minimum received optical power of all ONUs of the first PON port in the first cycle being between the maximum and minimum values ​​within the range of the weak light limiting threshold of the PON port, and the range of the weak light limiting threshold of the PON port including two integers with the smallest difference between the minimum received optical power of all ONUs of the first PON port in the first cycle, the larger of the two integers with the smallest difference between the minimum received optical power of all ONUs of the first PON port in the first cycle included in the range of the weak light limiting threshold of the PON port is determined as the weak light limiting threshold of the first PON port in the second cycle.

[0073] Understandably, when any value in the first set is an integer, in response to the minimum received optical power of all ONUs of the first PON port in the first period after rounding down being between the maximum and minimum values ​​in the first set, and the first set includes two integers with the smallest difference from the minimum received optical power of all ONUs of the first PON port in the first period after rounding down, the larger of the two integers with the smallest difference from the minimum received optical power of all ONUs of the first PON port in the first period after rounding down is determined as the threshold for weak light limitation of the first PON port in the second period.

[0074] For example, if the first set is {-33, -30, -26}, and the minimum received optical power of all ONUs of the first PON port in the first period after rounding down is -28, then the first set includes two integers with the smallest difference from the minimum received optical power of all ONUs of the first PON port in the first period after rounding down, namely -26 and -30. The larger of the two integers included in the first set with the smallest difference from the minimum received optical power of all ONUs of the first PON port in the first period after rounding down is determined as the threshold for weak light limitation of the first PON port in the second period. That is, between -26 and -30, the larger value -26 is determined as the threshold for weak light limitation of the first PON port in the second period.

[0075] Step 103. During the second cycle, the received light power of the first ONU of the first PON port is detected in real time. If the received light power of the first ONU of the first PON port is lower than the weak light limit threshold of the first PON port in the second cycle, the first ONU is monitored. If the received light power of the first ONU when it goes offline and comes back online in the second cycle is lower than the weak light limit threshold of the first PON port in the second cycle, the first ONU is taken offline.

[0076] In step 103, the first ONU is any one of the ONUs of the first PON port.

[0077] For example, the OLT can detect the received optical power of the first ONU on the first PON port in real time. The reason why the first ONU goes offline in the second cycle may be due to power failure or fault, etc. After power is restored or the fault is cleared, the first ONU can go online again.

[0078] Understandably, if the received optical power of the first ONU on the first PON port is lower than the weak light limit threshold of the first PON port in the second cycle, it indicates that the received optical power of the first ONU is too low. However, if the first ONU remains online, it is not necessary to force it offline to avoid sudden network outages and a poor internet experience for users. Therefore, if the received optical power of the first ONU when it goes offline and comes back online in the second cycle is lower than the weak light limit threshold of the first PON port in the second cycle, it is possible to force it offline (i.e., prohibit the first ONU from going online) when it goes offline and comes back online in the second cycle, in order to rectify the first ONU without affecting the user's internet experience as much as possible.

[0079] The optical power control method provided by the embodiments of the present invention will not affect currently online ONUs, even if the current ONU is in a low-light state. It will also avoid the problem of PON port low-light configuration rollback due to a lack of rectification conditions in the short term. In the next statistical period, the minimum optical power of the first PON port will not fall below the threshold of the previous period. Furthermore, with continuous rectification support, through periodic operation, the overall low-light limit threshold of the PON ports can be continuously improved, ultimately achieving the target value of -26dBm for the entire network.

[0080] The following is a specific example illustrating an embodiment of the optical power control method provided by the present invention.

[0081] This example uses an automated program to automatically summarize the received optical power of all user ONUs within a recent period (the raw data comes from the daily collection results of the provincial company) every 15 days. It then calculates the minimum optical power of all online ONUs during this period by PON port and sets the weak light limit of that PON port to the minimum optical power.

[0082] 1. Automatically summarize the received optical power of all user ONUs within a recent period (e.g., 15 days).

[0083] 2. Calculate the minimum optical power according to the PON port.

[0084] 3. Set the weak light limit of this PON port to the minimum optical power.

[0088]

[0089] As shown in Table 1, through four months of continuous rectification and deployment, the percentage of PON ports meeting the standard (optical power ≥ -26dBm) has steadily increased, while the number of PON ports below the target value has been continuously and irreversibly decreasing. At a rate of 2 percentage points per month, it is expected that after another year, the compliance rate of the low-light limitation threshold for PON ports across the entire network will reach over 95%. This will fundamentally solve the problem of low-light rectification difficulties faced by operators.
