[0059] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0060] Currently, the Optical Distribution Network (ODN) uses a hierarchical splitting scheme consisting of primary and secondary splitting. Due to factors such as attenuation in the downstream lines, the signal-to-noise ratio (SNR) at different output ports of the same splitter varies, thus affecting the service quality of operators.

[0061] If the optical signal output to the user end is controlled within a reasonable range during optical splitting, and the optical power is controlled within a certain range, the stability of the optical power can be ensured. At the same time, damage to PON (Passive Optical Network) equipment caused by excessive output optical power can be avoided, thereby improving the service quality of the optical network.

[0062] For operators, the service quality for different user levels should also be different, especially in areas where it is inconvenient to expand optical network construction or construction has not been carried out in a timely manner.

[0063] In short, there is still a lack of an optical power distribution method that can reasonably control the optical power reaching each user port and protect the optical signals of different users in different levels.

[0064] Reference Figure 1 , shows a flowchart of the steps of an optical power allocation method provided in an embodiment of the present invention, which may specifically include the following steps:

[0065] Step 101: Obtain the user service level of the user.

[0066] Among them, different user service levels can be set for users according to the packages subscribed by users or the users' usage scenarios. For example, the user service level can be set for users based on information such as the service registration handled by the operator according to the user (such as 1000-megabit broadband, 200-megabit broadband, etc.). The user service level can be set to A, B, C, D,... levels according to the level of service.

[0067] User service levels have corresponding optical power ranges, and service optical signal levels are set for each user service level, such as: Level A (S±T dbm, for example -18±0.5dbm); Level B (S±T±L dbm); Level C (S±T±2Ldbm).

[0068] Specifically, before distributing the optical power through the optical splitter, the user service level of the user corresponding to the receiving device connected to the output port of the optical splitter is first obtained, and the optical power range corresponding to each user service level is obtained.

[0069] Step 102: Allocate optical power to the output ports of the optical splitter connected to the user's receiving devices in descending order according to the user service level, so that the optical power value received by each receiving device is within the corresponding optical power range.

[0070] The user's receiving device may be a downstream optical splitter / user-side PON device, etc.

[0071] Specifically, after obtaining the optical power range corresponding to the receiving device connected to the output port of the splitter, the optical power input to the input port of the splitter can be allocated to the output port on the splitter connected to the user's receiving device according to the optical power range, so that the value of the optical power received by each receiving device is within its corresponding optical power range, ensuring the stability of the optical power received by the receiving device, and in the process of optical power allocation, it is allocated according to the priority of user service level from high to low, giving priority to ensuring the service quality of high user service level.

[0072] For example, the optical power range for users in user service level A is (a-b) dBm, and the optical power range for users in user service level B is (b-c) dBm. User service level A is higher than user service level B, with a>b>c. Therefore, optical power is allocated first to the output port of the optical splitter connected to the A receiving device corresponding to the A user service level, so that the optical power received by the A receiving device is stabilized within the range of (a-b) dBm. Then, optical power is allocated first to the output port of the optical splitter connected to the B receiving device corresponding to the B user service level, so that the optical power received by the B receiving device is stabilized within the range of (b-c) dBm. If the optical power is insufficient, the service quality of users in user service level A is prioritized, so that the optical power received by the A receiving device is stabilized within the range of (a-b) dBm.

[0073] In an embodiment of the present invention, the optical power input to the input port of the optical splitter is distributed to the output port of the optical splitter connected to the user's receiving device according to the optical power range corresponding to the user's user service level, so that the value of the optical power received by each receiving device is within its corresponding optical power range, thereby protecting the optical signals of different users according to the user service level and reasonably controlling the optical power to each receiving device. On the one hand, it can avoid wasting resources by allocating too much optical power to users with low user service levels, and on the other hand, it can allocate sufficient optical power to receiving devices with high user service levels, thereby ensuring the service quality of users with high user service levels.

[0074] In addition, in the process of optical power allocation, it is allocated according to the priority of user service level from high to low. When the optical power input to the input port of the optical splitter is insufficient, the service quality of users with high user service level can be guaranteed first.

[0075] Based on the above embodiment, a modified embodiment of the above embodiment is proposed. It should be noted that, in order to simplify the description, only the differences from the above embodiment are described in the modified embodiment.

[0076] In an optional embodiment of the present invention, allocating optical power to the output ports on the optical splitter connected to the user's receiving device in descending order according to the user service level includes: determining the median optical power of the optical power range; allocating optical power to the output ports on the optical splitter connected to the user's receiving device in descending order according to the user service level, so that the value of optical power received by each receiving device is the corresponding median optical power.

[0077] Specifically, when allocating the optical power input to the input port of the splitter to the output port on the splitter connected to the user's receiving device according to the optical power range, first determine the median optical power of the optical power range. For example, if the optical power range corresponding to user service level A is (a~b)dbm, then the median optical power of the optical power range corresponding to user service level A is (a+b) / 2dbm.

[0078] Then, optical power can be allocated to the output ports on the optical splitter connected to the user's receiving device in descending order according to the user's service level, so that the optical power received by each receiving device is its corresponding median optical power.

[0079] It should be noted that the above description uses the value of the optical power received by the receiving device as its corresponding median optical power as an example. In actual applications, the value of the optical power received by the receiving device can also be the maximum optical power, the minimum optical power, etc., which can be set according to actual needs. There is no limitation on this in the embodiments of the present invention.

[0080] In the above embodiment, receiving devices of different user service levels may be allocated optical powers of corresponding median optical powers, thereby ensuring optical power stability and user service quality.

[0081] In an optional embodiment of the present invention, after allocating optical power to the output ports on the optical splitter connected to the user's receiving devices in descending order according to the user service levels, it also includes: when the receiving device with the lowest user service level cannot receive the optical power of the corresponding median optical power, determining the minimum optical power value of the optical power range with the lowest user service level; and allocating optical power to the output port on the optical splitter connected to the receiving device with the lowest user service level based on the minimum optical power value, so that the receiving device with the lowest user service level receives the optical power of the corresponding minimum optical power value.

[0082] Specifically, in actual applications, the optical power input to the input port of the splitter may be insufficient, resulting in the remaining optical power being insufficient to be allocated to the receiving device corresponding to the lowest user service level after the optical power is allocated to users with high user service levels. Therefore, at this time, the service quality of the user with the lowest user service level can be reduced, and the minimum optical power value of the optical power range with the lowest user service level can be determined. Based on the minimum optical power value, optical power is allocated to the output port on the splitter connected to the receiving device with the lowest user service level, so that the receiving device with the lowest user service level receives the optical power corresponding to its minimum optical power value.

[0083] In the above embodiment, when the optical power input to the input port of the optical splitter is insufficient, the optical power received by the receiving device with the lowest user service level is reduced, and the service quality of the user with the lowest user service level is maintained at the standard quality, while the service quality of the user with the lowest user service level is prioritized to ensure the service quality of the user with a high user service level.

[0084] In an optional embodiment of the present invention, after allocating optical power to the output port on the optical splitter connected to the receiving device with the lowest user service level according to the minimum optical power value, it also includes: when the receiving device with the lowest user service level cannot receive the optical power of the minimum optical power value corresponding to it, determining the minimum optical power value of the optical power range; adjusting the optical power output by the output port on the optical splitter connected to the receiving device in sequence from low to high according to the user service level, so that the receiving device with the lowest user service level receives the optical power of the minimum optical power value corresponding to it; wherein the value of optical power received by the receiving device corresponding to each user service level is greater than or equal to the corresponding minimum optical power value.

[0085] Specifically, after allocating optical power to the output port on the optical splitter connected to the receiving device with the lowest user service level based on the minimum optical power, if the receiving device with the lowest user service level cannot receive the optical power of its corresponding minimum optical power value, it means that the service quality of the user with the lowest user service level does not meet the standard at this time. Therefore, according to the user service level, the optical power output by the output port on the optical splitter connected to the receiving device is adjusted from low to high, and the optical power received by other receiving devices with higher user service levels is allocated to the receiving device with the lowest user service level, so that the receiving device with the lowest user service level receives the optical power of its corresponding minimum optical power value, thereby ensuring that the user's service quality can meet the standard quality.

[0086] As an example, it includes user service level A, user service level B, user service level C and user service level D, among which user service level A>user service level B>user service level C>user service level D. When the receiving devices corresponding to user service level A, user service level B and user service level C all receive optical powers of their corresponding median optical powers, and the receiving device corresponding to user service level D cannot receive optical powers of its corresponding minimum optical powers, the optical power received by the receiving device corresponding to user service level C is first adjusted, and the optical power received by the receiving device corresponding to user service level C is adjusted from the median optical power to the minimum optical power, so as to allocate the optical power received by the receiving device corresponding to user service level C to the receiving device corresponding to user service level D. If, at this time, the receiving device corresponding to user service level D can receive optical power of its corresponding minimum optical power, the optical power adjustment is completed.

[0087] If at this time the receiving device corresponding to the D user service level still cannot receive the optical power of its corresponding minimum optical power, the optical power received by the receiving device corresponding to the B user service level is adjusted from the median optical power to the minimum optical power, so that the optical power received by the receiving device corresponding to the B user service level is allocated to the receiving device corresponding to the D user service level. If at this time the receiving device corresponding to the D user service level can receive the optical power of its corresponding minimum optical power, the optical power adjustment ends. If at this time the receiving device corresponding to the D user service level still cannot receive the optical power of its corresponding minimum optical power, the optical power received by the receiving device corresponding to the A user service level is adjusted until the receiving device corresponding to the D user service level receives the optical power of its corresponding minimum optical power.

[0088] It should be noted that when the optical power received by the receiving device with the highest user service level is adjusted from the median optical power to the minimum optical power, if the receiving device with the lowest user service level still cannot receive the optical power corresponding to the minimum optical power, the optical power adjustment is terminated to prioritize the service quality of users with high user service levels.

[0089] In the above embodiment, when the optical power input to the input port of the optical splitter is insufficient, the optical power received by the receiving device of the high user service level can be reduced, so that the optical power received by the receiving device corresponding to the high user service level can be allocated to the receiving device corresponding to the low user service level. While giving priority to ensuring the service quality of users with high user service levels, the service quality of users with low user service levels can be guaranteed.

[0090] In an optional embodiment of the present invention, before allocating optical power to the output port of the optical splitter connected to the user's receiving device in descending order according to the user service level, it also includes: evenly distributing the optical power input to the input port of the optical splitter to the output port of the optical splitter connected to the user's receiving device; obtaining the optical power output value output by the output port of the optical splitter and the optical power input value received by the receiving device; and calculating the optical power loss value / optical power loss rate between the output port of the optical splitter and the receiving device based on the optical power output value and the optical power input value, so as to allocate optical power to the output port of the optical splitter connected to the user's receiving device based on the optical power loss value / the optical power loss rate and the optical power range.

[0091] Among them, there will be a certain amount of optical power loss in the process of transmitting optical power from the output port of the splitter to the user's receiving device. Therefore, in order to ensure that the optical power value received by the receiving device is within its corresponding optical power range, it is necessary to first determine the optical power loss value / optical power loss rate between the output port of the splitter and the receiving device.

[0092] Specifically, the optical power input to the input port of the optical splitter is evenly distributed (other distribution methods, such as proportional distribution, may also be used) to the output port on the optical splitter connected to the user's receiving device, and the optical power output value output by the output port of the optical splitter and the optical power input value received by the receiving device are obtained. Based on the optical power output value and the optical power input value, the optical power loss value / optical power loss rate between the output port of the optical splitter and the receiving device is calculated, so that according to the optical power loss value / optical power loss rate and the optical power range, the optical power is distributed to the output port on the optical splitter connected to the user's receiving device, so that the optical power value received by each receiving device is within its corresponding optical power range.

[0093] In the above embodiment, by determining the optical power loss value / optical power loss rate between the output port of the optical splitter and the receiving device, the value of the optical power output to the receiving device can be accurately controlled so that the value of the optical power received by each receiving device is within its corresponding optical power range, thereby ensuring the user's service quality.

[0094] It should be noted that in addition to determining the optical power loss value / optical power loss rate through the above method, the optical power loss value / optical power loss rate between the output port of the splitter and the receiving device can also be obtained from the historical records. Of course, when the distance between the output port of the splitter and the receiving device is short, the optical power loss value / optical power loss rate can also be ignored. It can be set according to actual needs, and the embodiment of the present invention does not limit this.

[0095] In an optional embodiment of the present invention, according to the user service level, the optical power is allocated to the output port on the optical splitter connected to the user's receiving device in descending order, including: calculating the target optical power output value output by the output port on the optical splitter connected to the user's receiving device based on the optical power loss value / the optical power loss rate and the optical power range; according to the user service level, the optical power corresponding to the target optical power output value is allocated to the output port on the optical splitter connected to the user's receiving device in descending order.

[0096] Specifically, after calculating the optical power loss value / optical power loss rate between the output port of the optical splitter and the receiving device, the target optical power output value for the output port of the optical splitter connected to the user's receiving device can be calculated based on the optical power loss value / optical power loss rate and the optical power range. For example, if the optical power loss value is c dBm and the optical power range is (a-b) dBm, then the target optical power output value is within the range of (a+c-b+c) dBm. According to the user's service level, the output ports of the optical splitter connected to the user's receiving device are assigned the optical power corresponding to their target optical power output values, from high to low. This ensures that the target optical power output value, output from the output port of the optical splitter and reaching the receiving device after optical power attenuation, is within its corresponding optical power range, thereby ensuring the user's quality of service.

[0097] In the above embodiment, by determining the optical power loss value / optical power loss rate between the output port of the optical splitter and the receiving device, and calculating the target optical power output value output by the output port of the optical splitter connected to the user's receiving device based on the optical power loss value / optical power loss rate and the optical power range, the value of the optical power output to the receiving device can be accurately controlled, so that the value of the optical power received by each receiving device is within its corresponding optical power range, thereby ensuring the user's service quality.

[0098] In an optional embodiment of the present invention, after allocating optical power to the output port on the splitter connected to the user's receiving device in descending order according to the user service level, it also includes: allocating excess optical power input to the input port of the splitter to the output port on the splitter connected to the optical load.

[0099] Specifically, when the optical power input to the input port of the optical splitter is excessive, the excessive optical power may be transmitted to the optical load for storage.

[0100] In order to better understand the embodiments of the present invention, refer to the following Figures 2 to 4 An exemplary description is given.

[0122] 5. Primary spectroscopic process

[0123] In advance, the system sends a splitting interval (user receiving optical power interval / optical power range) to the memory.

[0124] (1) The optical splitter distributes optical power to each port in a geometric ratio, generally evenly.

[0125] (2) The “transmitted and received light intensity counter” counts the initial light power output.

[0126] (3) At the same time, the “lower-level optical splitter / user-end PON device” feeds back the optical power input.

[0127] (4) Implement interval power median comprehensive allocation based on the power reaching the target user (lower-level optical splitter / user-end PON equipment) to complete the first splitting of each port.

[0128] Implement power adjustment based on the optical power feedback from users.

[0129] (5) Adjust the excess optical power to the optical load output.

[0130] 6. Secondary spectroscopic process

[0131] (1) The light emission and light receiving values are counted by the “light receiving and light receiving intensity counter”.

[0132] The optical power transmitted by port i and the optical power received by the PON device at port i are counted, and the difference between them is the power that the optical splitter needs to further adjust.

[0133] (2) Using the user signal range of the highest service level as a reference, set the optical power distribution of each port.

[0134] Generally, the CPU calculates whether the median value of the optical power interval of each service level can be achieved. Under the current optical power input, when the median value of level A can be achieved, the median values of the power of levels B, C, D... can be further achieved.

[0135] When the median power of the lowest level D cannot be achieved, calculate whether the lowest power of its interval can be achieved. If not, then gradually reduce the power ranges of the upper levels C, B, and A to the lowest level of their interval.

[0136] On some lines with large optical attenuation, when the above minimum service level range cannot ensure the service quality of the lowest level D users, priority is given to ensuring the optical signal service quality of high-level users.

[0137] (3) Spectroscopy is performed according to the secondary spectroscopic reference value, and the CPU performs secondary spectrometry based on the calculation results.

[0138] (4) If there is excess optical power signal, readjust the excess optical power to the optical load output. Each optical splitter module and optical load completes the output of the excess optical power.

[0139] Among them, the current ODN network adopts a hierarchical solution of primary splitting and secondary splitting. The problem is that the optical power allocated to different user PON devices is uneven, affecting the service quality.

[0140] Compared with the prior art, the embodiments of the present invention have the following main advantages:

[0141] (1) Set the optical signal interval service quality according to the user's service level.

[0142] (2) Automatically collect the optical power of users at each port and provide reasonable optical power for each port through statistical calculation.

[0143] (3) In areas where it is inconvenient to expand the optical network construction or construction has not been completed in a timely manner, ensure the optical power distribution of high-level users.

[0144] (4) By setting user levels and allocating optical power intervals, plan the power allocated to each port.

[0145] (5) According to the actual power of the user's PON and the line power, set the minimum threshold value or average value and other conditions, and automatically implement power allocation, difference supplement and other functions.

The processor 610 may include one or more processing units; preferably, the processor 610 may integrate an application processor and a modem processor, wherein the application processor primarily processes the operating system, user interface, and application programs, while the modem processor primarily handles wireless communications. It is understood that the modem processor may not be integrated into the processor 610.

[0184] The electronic device 600 may also include a power supply 611 (such as a battery) to supply power to each component. Preferably, the power supply 611 may be logically connected to the processor 610 through a power management system, thereby enabling the power management system to manage functions such as charging, discharging, and power consumption.
