In the current network environment, the main problem of ONU optical attenuation is smaller than a threshold value, such as smaller than-27 dBm. After the ONU light attenuation is smaller than the threshold value, the ONU gradually generates the problems of error rate increase and the like due to insufficient light receiving power, and the user surfing experience is affected. In this time, the optical attenuation needs to be cured, the power loss of the line side light is reduced by means of line side fault investigation and the like, so that the optical attenuation value of the ONU is more than-27 dBm, and the satisfaction degree of broadband service of a user can be improved by optical attenuation curing.

Fig. 2 is a schematic flow chart of an optical attenuation processing method of an optical network unit provided in the present application. As shown in fig. 2, a method for processing optical attenuation of an optical network unit includes:
s201, acquiring an optical attenuation value and an error rate of each optical network unit in an optical network;
the light attenuation value is one light attenuation value acquired in unit time, or any one of a minimum light attenuation value, a maximum light attenuation value and an average light attenuation value in a plurality of light attenuation values acquired in unit time. The unit time may be 5 minutes, 30 minutes, one hour, 2 hours, 4 hours, 12 hours, one day, one week, one month, or the like. The bit error rate is the number of bit errors collected in a unit time, and the bit error rate may include the number of uplink frame errors and the number of downlink frame errors, i.e. frame error rate=frame error number/collection time. The number of errors may include the number of errors for a variety of reasons, such as frame delimiter errors (frame delimiter error), frame BIP errors (frame BIP errors), and the like.
S202, obtaining a light attenuation parameter according to the light attenuation value and the bit error rate, wherein the light attenuation parameter is in direct proportion to the light attenuation value and the bit error rate;
further, obtaining a light attenuation degradation rate according to the light attenuation value; specifically, if the light attenuation value is not less than the preset light attenuation experience degradation threshold, confirming that no light attenuation degradation rate exists, wherein the preset light attenuation experience degradation threshold is a preset experience value, for example, according to a general rule, the light attenuation standard degradation threshold is-27 dBm, the preset light attenuation experience degradation threshold can be set to be-28 dBm, -29dBm or-30 dBm, that is, the preset light attenuation experience degradation threshold is lower than the light attenuation standard degradation threshold, so that when the light attenuation is lower than the light attenuation standard degradation threshold, no error code is generated due to immediate performance degradation, and only when the light attenuation experience degradation threshold is lower than the preset light attenuation experience degradation threshold, the error code is possibly generated, and of course, the preset light attenuation experience degradation threshold can be set to be equal to the light attenuation standard degradation threshold as required; if the light attenuation value is smaller than a preset light attenuation experience degradation threshold, continuously judging whether the light attenuation value is smaller than a preset light attenuation acquisition minimum light power or not; if the light attenuation value is smaller than the preset light attenuation value, the light attenuation value cannot be acquired, and the processing requirement cannot be met only by light attenuation correction, for example, the optical cable is replaced by other ways, but the main invention point of the method is to process the light attenuation under the condition that the optical cable is not replaced, so that the situation is not discussed deeply; if the light attenuation value is not smaller than the preset light attenuation acquired minimum light power, a first difference value between the preset light attenuation experience degradation threshold and the light attenuation value, a second difference value between the preset light attenuation experience degradation threshold and the preset light attenuation acquired minimum light power are acquired, the light attenuation degradation rate is determined according to the first difference value and the second difference value, and the light attenuation degradation rate is in direct proportion to the first difference value and in inverse proportion to the second difference value.
Obtaining an error rate normalization value according to the error rate; specifically, the data directly acquired by the server may be an error code number or an error code rate, which is determined by the acquisition device, and when the acquired value is the error code rate, it needs to be determined whether the error code rate is greater than a preset error code threshold value, where the preset error code threshold value is used to indicate that the optical cable is unable to communicate when the error code rate is greater than the value, and the preset error code threshold value is usually set to be smaller, for example 10 -4 ；
If so, that is, in a state of no communication at this time, the processing needs to be performed preferentially, so that the obtained preset error rate normalization value needs to be set larger,the priority of the light attenuation parameter can be improved, and the bit error rate normalization value is confirmed to be a preset bit error rate normalization value, wherein the preset bit error rate normalization value is usually set to be far greater than the bit error rate, for example, 10 4 ；
If not, that is, if there is a condition to be optimized to a certain extent at this time, because the bit error rate is not a negative number but is smaller than the preset bit error threshold value which is already set, in order to influence the light attenuation parameter conveniently, the bit error rate needs to be amplified to obtain a bit error rate normalization value, so that the bit error rate normalization value is confirmed to be in direct proportion to the bit error rate, and the bit error rate normalization value is inversely proportional to the preset bit error threshold value.
Obtaining the light attenuation parameter according to the light attenuation degradation rate and the error rate normalization value; specifically, the greater the light degradation rate and the bit error rate normalization value, the higher the priority it needs to maintain, so the greater the light degradation parameter obtained by the light degradation rate and the bit error rate normalization value needs to be proportional to the light degradation parameter, and the light degradation rate and the bit error rate normalization value can be combined into the light degradation parameter to be uniformly considered by obtaining the product or the weighted sum of the light degradation rate and the bit error rate normalization value; and then determining the specific value of the light attenuation parameter according to the product or the weighted sum.
S203, according to the light attenuation parameters of each optical network unit, the priority of all the optical network units with the acquired light attenuation parameters is ordered, wherein the higher the light attenuation parameters of the optical network units are, the higher the priority of the optical network units is;
specifically, all ONUs are collected according to the light attenuation parameters acquired in step S202, and then are ordered in a sequence from big to small, the higher the priority of the corresponding processing is, so that an operator can select a plurality of ONUs from front to back for processing according to the self-capacity condition.
And S204, sending the identification of the optical network unit to the optical attenuation processing terminal according to the order of the priority from high to low.
Specifically, unique number identification is performed on all the optical network units in advance, after the optical network units are sequenced according to the light attenuation parameters, the server sends the identification of the optical network units to the light attenuation processing terminal, an intelligent engineer of an operator obtains the sequencing situation of the identification from the light attenuation processing terminal, and the processing sequence and the processing workload of the optical network units are arranged according to the sequencing situation of the identification, so that the light attenuation processing efficiency is improved.
According to the method provided by the embodiment, the optical attenuation value and the error rate of each optical network unit in the optical network are obtained by aiming at each optical network unit; obtaining a light attenuation parameter according to the light attenuation value and the error rate, wherein the light attenuation parameter is in direct proportion to the light attenuation value and the error rate; according to the light attenuation parameter of each optical network unit, the priority of the plurality of optical network units is ordered, wherein the higher the light attenuation parameter of the optical network unit is, the higher the priority of the optical network unit is; the method for transmitting the identification of the optical network unit to the optical attenuation processing terminal according to the order of the priority from high to low realizes that the ONU generating the error code due to the optical attenuation can be preferentially processed under the condition of limited optical attenuation processing capacity of an operator, thereby improving the effectiveness of the optical attenuation processing, improving the working efficiency and the customer experience satisfaction degree, and reducing the time consumption of manually calculating the processing priority and the probability of possible error.
The following describes a detailed method for processing optical attenuation of an optical network unit according to the present application in conjunction with a specific embodiment.
Fig. 3 is a schematic diagram of a light attenuation processing method of an optical network unit provided in the present application. As shown in fig. 3, on the basis of the above embodiment, a detailed description is given of an implementation manner of obtaining, for each optical network unit in the optical network, an optical attenuation value and an error rate of the optical network unit.
S301, obtaining a light attenuation degradation rate according to the light attenuation value;
specifically, when the starting and ending times of a unit time are T (i-1) and Ti, respectively, i is an integer of 1 or more, the duration t=ti-T (i-1) of the unit time. Then a total of m light attenuation values are collected and stored within the time length, which are DCY respectively 1 、DCY 2 ...DCY m The light attenuation value in the period of time may be an average value in the period of time, or may be a maximum value (optimal value) or a minimum value (worst value);
i.e.
Or alternatively
Or alternatively
And then comparing the light attenuation value with a preset light attenuation experience degradation threshold and a preset light attenuation acquisition minimum light power respectively, and determining the numerical value of the light attenuation degradation rate according to the comparison result.
S302, judging whether the error rate is larger than a preset error threshold value, if so, executing S303, otherwise, executing S304;
s303, confirming that the error rate normalized value is a preset error rate normalized value;
s304, confirming that the bit error rate normalized value is in direct proportion to the bit error rate, and the bit error rate normalized value is in inverse proportion to the preset bit error threshold value.
Specifically, the number of errors per unit time is the number of errors per unit time when the number of errors acquired twice at the beginning and the end of the unit time are EN (i-1) and ENi, respectively: en=eni-EN (i-1), the bit error rate FER is:
FER＝EN/T＝(ENi-EN(i-1))/T。
the preset bit error threshold value ETTHR is the highest threshold value that can be used for communication, when the bit error rate FER is greater than the preset bit error threshold value ETTHR, the bit error rate normalization value nor_fer needs to be defined as a larger value, and when the bit error rate FER is greater than zero and less than the preset bit error threshold value ETTHR, the bit error rate FER is normalized in an amplifying manner, namely:
NOR_FER＝FER/ETTHR，0≤FER≤ERTHR；
NOR_FER＝∞，FER>ERTHR。
because the value of the error rate is amplified, the situation of the error rate can be more emphasized when the optical attenuation parameters are acquired later, and the ONU generating the error code due to the optical attenuation can be preferentially processed under the condition that the optical attenuation processing capacity of an operator is limited, so that the effectiveness of the optical attenuation processing is improved, and the working efficiency and the customer experience satisfaction are improved.
S305, obtaining a product or a weighted sum of the light degradation rate and the error rate normalization value;
s306, determining the light attenuation parameter according to the product or the weighted sum.
Specifically, according to whether the light-decay parameter is prone to the light-decay rate DEG or the bit error rate normalization value NOR_FER, weight regulators p and q are defined, wherein p is more than 0, q is more than 0, and weights of the light-decay rate DEG and the bit error rate normalization value NOR_FER in the light-decay parameter processing process are distributed through the weight regulators, namely:
NCS＝DEG×p+NOR_FER×q；
the actual values of p and q are determined according to the actual needs, for example, p=25, q=4, and the above formula becomes: ncs=25dec+4nor_fer.
The above formula has a wide application range, but it is necessary to provide further limitation conditions, for example, that only the light degradation rate and the error rate exist simultaneously, the light degradation needs to be treated, and at this time, thr3. Ltoreq.DCY. Ltoreq.Thr1 and 0 < FER. Ltoreq.ERTHR is required. The limiting condition is that only the light attenuation rate needs to be treated when the light attenuation rate exists, and at the moment, thr3 is not more than DCY and not more than Thr1 is needed, wherein Thr1 is the light attenuation standard degradation threshold, and Thr3 is the preset light attenuation acquisition minimum light power.
When the light attenuation value DCY is smaller than the preset light attenuation experience degradation threshold Thr2 and the bit error rate FER is smaller than the preset bit error threshold value ETTHR, the light attenuation degradation rate DEG and the bit error rate normalization value nor_fer are both larger than zero, and the light attenuation degradation rate DEG and the bit error rate normalization value nor_fer can be quickly combined in a product mode to obtain a light attenuation parameter NCS, namely:
NCS＝DEG×NOR_FER。
it should be noted that, the preset light attenuation empirical degradation threshold Thr2 is a human preset empirical value, and the preset light attenuation empirical degradation threshold Thr2 is lower than the light attenuation standard degradation threshold Thr1, so that when the light attenuation is lower than the light attenuation standard degradation threshold Thr1, no error is generated due to immediate performance degradation, and only when the light attenuation is lower than the preset light attenuation empirical degradation threshold Thr2, the error is possibly generated, and of course, the preset light attenuation empirical degradation threshold Thr2 may also be set to be equal to the light attenuation standard degradation threshold Thr1 as required; if the light attenuation value is smaller than the preset light attenuation acquisition minimum light power Thr3, the light attenuation value cannot be acquired, at the moment, the processing requirement cannot be met by light attenuation processing, and the light attenuation is processed under the condition that the optical cable is not replaced by other ways, for example, the optical cable is replaced, so that the situation is not discussed deeply. In addition, the period of light attenuation is preferably longer than the unit time period of light attenuation and bit error rate acquisition, so that the light attenuation value and bit error rate of the ONU after light attenuation are both in the qualified interval, so that DCY is greater than Thr1 and fer=0 in the data acquisition before the next light attenuation processing period starts, i.e. the ONU after light attenuation is not listed in the processing list of the next period.
According to the embodiment of the invention, the light attenuation degradation rate is obtained according to the light attenuation value, the relation between the error rate normalized value and the error rate and the preset error threshold value is obtained according to the error rate and the preset error threshold value, the means of obtaining the light attenuation parameter is obtained according to the product or the weighted sum of the light attenuation degradation rate and the error rate normalized value, the rapid solving process of the light attenuation parameter is realized, and the influence of two important factors of the light attenuation value and the error rate on the light attenuation is referenced in the process, so that the solving result is more reliable, the ordering of light attenuation processing priorities of different ONUs by an auxiliary engineer is facilitated, the time consumption of manual judgment and the probability of occurrence of judgment errors are reduced, and the working efficiency is improved.
Fig. 4 is a schematic flow chart of an optical attenuation processing method of an optical network unit provided in the present application. As shown in fig. 4, in the above embodiment, an implementation manner of determining the magnitude of the light degradation rate from the comparison result in obtaining the light degradation rate from the light degradation value will be described in detail.

s402, judging whether the light attenuation value is smaller than a preset light attenuation acquisition minimum light power, if not, executing S403, and if so, confirming that the light attenuation degradation rate cannot be acquired;
specifically, thr1 is the optical attenuation standard degradation threshold of the ONU, for example Thr1 may be set to-27 dBm; thr2 is an empirical degradation threshold for optical attenuation of an ONU, for example Thr2 may be set to-28 dBm, -29dBm, or-30 dBm; thr2 is an empirical value, i.e. when the optical attenuation value of the ONU is lower than the degradation threshold of the optical attenuation standard, no error is generated due to performance degradation on the horse, and only when the optical attenuation value is lower than Thr2, the error is likely to be generated. Thr2 is not the same according to ONUs of different models, and thr2=thr1 may also be set; thr3 is the preset optical attenuation acquisition minimum optical power of the ONU, for example Thr3 may be set to-40 dBm. Therefore, deg=0 when DCY is ≡thr2.
S403, acquiring a first difference value between the preset light attenuation experience degradation threshold and the light attenuation value;
specifically, when Thr3 is less than or equal to DCY < Thr2, a first difference value Thr2-DCY is obtained.

Specifically, the obtained first difference value and the second difference value are compared to obtain a light degradation rate, namely:
DEG＝(Thr2-DCY)/(Thr2-Thr3)。
the above embodiments are further described with respect to a specific set of parameters.
