s100, receiving an initial value of the extinction ratio and an initial value of the error rate of the transmitting end, debugging the optical power of the transmitting end according to a preset optical power debugging rule, and generating optical power debugging information.
In some embodiments, the initial value of the extinction ratio and the initial value of the bit error rate of the transmitting end are set by a commissioning engineer. For example, the extinction ratio may be written as ModDebug _ ADC, the initial value of ModDebug _ ADC is set to x5F (x in x5F represents hexadecimal), the initial value of the set extinction ratio is smaller than the target value of the extinction ratio to be debugged, and the debug engineer only needs to make the initial value of the extinction ratio smaller than x8F, assuming that the target value of the extinction ratio is x 8F. Similarly, the error rate is recorded as EA _ Bias, an initial value of the EA _ Bias is set to be x400, and the initial value of the error rate can enable the transmitting end to have poor transmission and the like when transmitting light, so that the error rate can be conveniently debugged in the subsequent steps. The purpose of the method is to guarantee that only debugging is needed in the direction of increasing the extinction ratio or the error rate during debugging when the extinction ratio and the error rate are balanced, so as to avoid the problem of needing to debug repeatedly. In other embodiments, the initial value of the extinction ratio and the initial value of the error rate may be set according to actual conditions, as long as the purpose of debugging in one direction can be achieved, and the application does not limit the initial values of the extinction ratio and the error rate.
In some embodiments, the optical power commissioning information includes optical power commissioning pass and optical power commissioning failure. The commissioning engineer sets the initial values of the acquisition points, for example, the initial values of the acquisition points may be set to 30, the launch end commissioning system obtains the optical power matched with the acquisition points according to the initial values of the acquisition points, the values of the optical power are related to the acquisition points, and each acquisition point corresponds to one optical power. And then, if the optical power corresponding to the acquisition point updated by the acquisition point step length each time is within the preset optical power target range, detecting whether the optical power corresponding to the acquisition point updated by the acquisition point step length each time is within the preset optical power target range. And if the transmitting terminal debugging system detects that the value of the optical power is within the preset optical power target range, generating an optical power debugging qualification, otherwise, proving that an abnormal condition occurs in the transmitting terminal, generating a debugging failure result by the transmitting terminal debugging system, and finishing debugging. In this embodiment, the preset optical power target range may be set to be between 2dbm and 4dbm, the step length of the collection point may be set to be 2, and the number of times of updating the preset collection point may be set to be 30.
In some embodiments, the commissioning engineer may also set initial values of two acquisition points, which are respectively recorded as a first initial acquisition point and a second initial acquisition point, set the first initial acquisition point to be 30, and the second initial acquisition point to be 80, and then respectively obtain a first initial optical power matching the first initial acquisition point, and a second initial optical power matching the second initial acquisition point, if the first initial optical power is on the left side of the preset optical power target range, that is, the first initial optical power is less than 2dbm, and the second initial optical power is greater than 4dbm, a bisection method may be used, that is, an average value of the first initial acquisition point and the second initial acquisition point is obtained, which is recorded as a third initial acquisition point. And then, acquiring a third initial optical power matched with the third initial acquisition point, and then performing next debugging according to comparison between the third initial optical power and a preset optical power target range, which is not described herein again.
S200, if the optical power debugging information is in optical power debugging qualification, the wavelength of the transmitting end is debugged according to a preset wavelength debugging rule, and wavelength debugging information is generated.
In some embodiments, the wavelength tuning information includes wavelength tuning pass and wavelength tuning fail. After the optical power is adjusted to be acceptable, the wavelength needs to be further adjusted because the wavelength and the optical power can affect each other, so that a balance state between the wavelength and the optical power is achieved.
In some embodiments, after the wavelength of the transmitting end is adjusted by the adjustment engineer, the TEC temperature (i.e. the semiconductor cooler) inside the transmitting end may be changed, thereby affecting the optical power adjusted by the above steps. Therefore, the wavelength of the transmitting end needs to be firstly debugged, and the steps are as follows:
a1. and acquiring a temperature value of the transmitting terminal. And obtaining a wavelength debugging value based on the temperature value of the transmitting terminal and a preset conversion reference value. And the transmitting end debugging system reads the temperature values matched with the acquisition points in the S100 step in the semiconductor refrigerator, wherein each acquisition point also corresponds to one temperature value. For example, the temperature value of the transmitting terminal read by the transmitting terminal debugging system is 25 ℃. In the present embodiment, the predetermined conversion reference value is set to 0.09 nm/deg.C. And multiplying the temperature value of the transmitting end by a preset conversion reference value to be recorded as a wavelength debugging value, wherein the wavelength debugging value is 2.25nm. In other embodiments, the preset conversion reference value is set according to actual conditions.
a2. And obtaining a wavelength target range based on the target wavelength and the wavelength debugging value. In this example, the target wavelength was 1529.55nm, and the target wavelength range was [1527.25nm to 1531.8nm ] was obtained based on the target wavelength of 1529.55nm and the wavelength adjustment value of 2.25nm. In other embodiments, the wavelength tuning value may also be set to a value smaller than 2.25nm and larger than 0nm, for example, the wavelength tuning value is set to 0.04nm, the target wavelength range is obtained [1529.53nm to 1529.57nm ], and the target wavelength may be set according to the actual situation.
a3. Updating the wavelength of the transmitting end based on the wavelength step length, detecting whether the updated wavelength is in the wavelength target range after the wavelength is updated by the wavelength step length each time, and if the wavelength is detected to be in the wavelength target range, generating a qualified wavelength for debugging; and if the wavelength is detected not to be in the wavelength target range, generating a wavelength debugging failure. In this embodiment, the wavelength step is set to 0.1nm, the wavelength is updated by the wavelength step 0.1nm each time, for example, if the value of the wavelength obtained by the transmission end tuning system before being updated is 1528.5nm, the wavelength reaches the target wavelength range [1527.25nm to 1531.8nm ] after the wavelength is updated by the wavelength step 0.1nm for the sixth time, and the generated wavelength is qualified for tuning. Meanwhile, a debugging engineer may set a preset wavelength updating time, for example, the preset wavelength updating time is 10, and if the wavelength is updated by the wavelength step length of 0.1nm for 10 times, the updated wavelength does not reach the target wavelength range [1527.25nm to 1531.8nm ], and a wavelength debugging failure is generated. In other embodiments, the wavelength step may also be set to other values such as 0.2nm according to the actual situation, and the preset wavelength update times may be set or not set according to the actual situation, and meanwhile, the wavelength step or the set preset wavelength update times are not limited in this application.
In some embodiments, if the updated wavelength does not reach the target wavelength range [1529.1nm to 1530nm ], the debugging engineer may modify the temperature of the TEC inside the transmission end again, then repeat steps a1 to a3, determine whether the wavelength after debugging reaches the target wavelength range [1529.1nm to 1530nm ], and if the wavelength after debugging does not reach the target wavelength range [1529.1nm to 1530nm ], generate the wavelength debugging failure information.
In some embodiments, if the wavelength tuning information is that the wavelength tuning is qualified, but the optical power generated by the transmitting end tuning system fails to be tuned due to the change of the wavelength, the optical power needs to be tuned again, that is, the optical power re-tuning step is performed. The light power readjusting steps are as follows:
b1. a first acquisition Point and a second acquisition Point are obtained. In this embodiment, the initial value of the acquisition point is updated by the acquisition point step size, the acquisition point updated by the acquisition point step size for the first time is regarded as the first acquisition point, and the acquisition point updated by the acquisition point step size for the second time is regarded as the second acquisition point. In other embodiments, the acquisition point updated by the acquisition point step length m times may be regarded as a first acquisition point, and the acquisition point updated by the acquisition point step length m + i times may be regarded as a second acquisition point, where m and i are both positive integers greater than 1. For example, the first acquisition point and the second acquisition point acquired by the transmitting end debugging system are 32 and 36, respectively.
b2. Acquiring second optical power matched with the first acquisition point, and recording the first acquisition point and the second optical power as a first coordinate point; and acquiring third optical power matched with the second acquisition point, and recording the second acquisition point and the third optical power as a second coordinate point. In this embodiment, the transmitting end commissioning system obtains the second optical power matched with the first acquisition point 32, for example, the second optical power is 8dbm, and then the first coordinate point is (32, 8). Similarly, the transmitting end commissioning system obtains a third optical power matched with the second acquisition point 36, for example, the third optical power is 12dbm, and then the first coordinate point is (36, 12).
b3. And generating an optical power slope value according to the first coordinate point and the second coordinate point. In this embodiment, if the absolute value of the quotient between the difference between the third optical power and the second optical power and the difference between the second collection point and the first collection point is recorded as the optical power slope value, | (36-32)/(12-8) | =1, where the optical power slope value is 1.
b4. The third optical power is updated based on the optical power slope value. In the present embodiment, the third optical power is updated in steps of the inverse of the optical power slope value based on the optical power slope value 1. In step S100, if the predetermined optical power target range is [2dbm to 4dbm ], the third optical power value needs to be decreased by taking the inverse of the optical power slope value as a step length. In other embodiments, if the value of the third optical power is less than 2dbm, the value of the third optical power needs to be increased by a step size of an inverse of the value of the optical power slope.
b5. And detecting whether the updated third optical power is in a preset optical power target range, and if so, generating an optical power debugging qualification. In this embodiment, the commissioning engineer may set the preset optical power update frequency, for example, set the preset optical power update frequency as 6 times, and if the third optical power is updated for 6 times or less than 6 times with the inverse of the optical power slope value as a step length, and the updated third optical power is within [2dbm to 4dbm ], the transmitting end commissioning system generates an optical power commissioning condition, and the optical power re-commissioning procedure is completed. And if the inverse of the optical power slope value is taken as the step length, updating the third optical power for more than 6 times, keeping the updated third optical power out of [ 2dbm-4 dbm ], and recording the acquisition point matched with the last updated third optical power as a first retuned acquisition point, wherein the acquisition point matched with the last updated third optical power is smaller than a preset acquisition point limit value. Then, the debugging engineer can update the first remodulated collection point within the preset collection point updating times according to the collection point step length again, and after the first remodulated collection point is updated with the collection point step length each time, remodulated luminous power matched with the updated first remodulated collection point is obtained, the transmitting end debugging system detects whether the remodulated luminous power is within [ 2dbm-4dbm ], and if the transmitting end debugging system detects that the remodulated luminous power is within [ 2dbm-4dbm ], an optical power debugging condition is generated. If the transmitting end debugging system detects that the readjusted optical power is not in [ 2dbm-4dbm ], or the updated first readjusted acquisition point is greater than the limit value of the preset acquisition point, the transmitting end debugging system fails to generate the optical power debugging, and the optical power readjusting program is ended. The limit value of the preset collection point may be set to 255, in other embodiments, the limit value of the preset collection point may be set according to practical situations, and the limit value of the preset collection point is not limited in the present application.
S300, if the wavelength debugging information is that the wavelength debugging is qualified, debugging the initial value of the error rate according to a preset error rate debugging rule, and generating error rate debugging information.
In some embodiments, the error rate debugging information includes error rate debugging pass and error rate debugging fail. And updating the initial value of the error rate based on the error rate step length to obtain a first error rate. In this embodiment, the initial value of the error rate EA _ Bias is x400, the error rate step is x80, and EA _ Bias may be increased by the error rate step x80 to obtain a first error rate x480. In other embodiments, the value of the error rate step may be set according to actual conditions, and the value of the error rate step is not limited in the present application. In order to improve the debugging efficiency, the debugging engineer may set the error rate update times according to actual conditions, for example, set the error rate update times to 3 times, and update the initial value of the error rate with the error rate step size x80 at each time to obtain the first error rate. The transmitting end debugging system detects whether the first error rate is within a preset error rate target range, and if the number of times of updating the initial value of the error rate by using the error rate step length x80 is less than or equal to 3, the transmitting end debugging system detects that the first error rate is within the preset error rate target range, and the error rate is generated to be qualified in debugging; and if the times of updating the initial value of the error rate by using the error rate step length x80 are more than 3 times, the transmitting terminal debugging system detects that the first error rate is not in the preset error rate target range, and error rate debugging failure is generated. In other embodiments, the number of bit error rate updates may also be set to 5, and the value of the number of bit error rate updates is not limited in the present application.
S400, if the error rate debugging information is that the error rate debugging is qualified, updating the initial value of the extinction ratio by a preset extinction ratio updating rule to obtain a first extinction ratio.
In some embodiments, the initial value of the extinction ratio is updated in extinction ratio steps, and whether the number of times of updating the extinction ratio steps is equal to N is detected, wherein N is an integer greater than 1. In this embodiment, the initial value of the extinction ratio ModDebug _ ADC is x5F, and the step size of the extinction ratio is x5. When the transmitting end debugging system detects that the updating times of the extinction ratio step length is equal to N, the result of updating the initial value of the extinction ratio by the extinction ratio step length for the (N-1) th time is used as the first extinction ratio. And taking the result of updating the initial value of the extinction ratio by the extinction ratio step length N time as a second extinction ratio. The debug engineer may set the value of N to 5, or may set the value of N to another numerical value such as 8, and the present application does not limit the value of N. And taking the result of updating the initial value of the extinction ratio by the extinction ratio step length for the 4 th time as the first extinction ratio, wherein the first extinction ratio is x73. The result of updating the initial value of the extinction ratio by the extinction ratio step 5 times is taken as the second extinction ratio, and the second extinction ratio is x78. And then, the transmitting terminal debugging system detects whether the second extinction ratio is within a preset extinction ratio target range, and if the second extinction ratio is not within the preset extinction ratio target range, the first error rate is updated based on the error rate step length to obtain a second error rate. In this embodiment, the first bit error rate is updated by a bit error rate step size x80, and the preset extinction ratio target range is [ x5F-xFF ], in other embodiments, the preset extinction ratio target range may also be other ranges. And then, the transmitting end debugging system acquires the extinction ratio matched with the second error rate and records the extinction ratio as a third extinction ratio. And finally, the transmitting terminal debugging system detects whether the third extinction ratio is within a preset extinction ratio target range, and if the third extinction ratio is within the preset extinction ratio target range, a debugging qualified result is generated.
In some embodiments, if the third extinction ratio is not within the preset extinction ratio target range and the second error rate is less than the preset error rate limit value, updating the second error rate based on the error rate step. And if the updated second error rate is greater than or equal to the preset error rate limit value, the debugging system of the transmitting end generates a debugging failure result. In this embodiment, the predetermined bit error rate limit value is xFFF, and in other embodiments, the predetermined bit error rate limit value may be set according to an actual requirement. And when the updated second error rate is greater than or equal to the preset error rate limit value xFFF, the transmitting end debugging system generates a debugging failure result, and the debugging is finished.
In some embodiments, if the transmitting end debugging system detects that the extinction ratio is qualified in debugging, but due to the change of the extinction ratio, the transmitting end debugging system detects that the error rate debugging information is error rate debugging failure aiming at the error rate which is qualified in debugging, the error rate needs to be debugged again, and then the error rate re-debugging step is performed. The error rate readjusting step comprises:
c1. updating the first error rate based on the error rate step length, and updating the initial value of the extinction ratio based on the extinction ratio step length.
c2. And the transmitting terminal debugging system detects whether the updated extinction ratio is within a preset extinction ratio target range, and if the updated extinction ratio is detected to be within the preset extinction ratio target range, then detects whether the updated error rate is within a preset error rate target range. And if the updated error rate is detected to be within the preset error rate target range, the generated error rate is qualified for debugging, and the error rate readjustment is finished. In this embodiment, the first bit error rate is increased by a bit error rate step x80, the first bit error rate at this time is x480, the initial value of the extinction ratio is decreased by 2 times by an extinction ratio step x5, an updated extinction ratio is obtained as x56, which is recorded as a fourth extinction ratio, and the fourth extinction ratio is x56. In other embodiments, the first bit error rate may be decreased by a bit error rate step x80, or the initial value of the extinction ratio may be increased by an extinction ratio step x 52 times or more, and the updating manner of the first bit error rate and the initial value of the extinction ratio is not limited in the present application.

In this embodiment, the first error rate needs to be increased again by x80, and the number of times of increasing the first error rate may be set according to actual conditions, for example, may be set to 3 times or 5 times. And after the first error rate is increased every time, acquiring the extinction ratio matched with the first error rate after each updating, and detecting whether the extinction ratio is in the preset extinction ratio target range. And if the transmitting end debugging system detects that the extinction ratio is within the preset extinction ratio target range and the updated first error rate is also within the preset error rate target range, the error rate debugging is qualified, and the error rate readjustment is finished. If the transmitting end debugging system detects that the updated first error rate is not within the preset error rate target range, the step c1 needs to be returned to for debugging again, and details are not repeated herein.
c22.

In the method for debugging the transmitting end of the DWDM optical module of this embodiment, first, an initial value of an extinction ratio of the transmitting end is set, so that the extinction ratio of the transmitting end is smaller than a target value of a debugged extinction ratio, and an initial value of a bit error rate is set, so that transmission of the transmitting end is poor, and a debugging direction of the extinction ratio and the bit error rate is determined, so that debugging is performed only in a direction of increasing the extinction ratio or the bit error rate, and the debugging time length is reduced. Then, the transmitting terminal is debugged according to the sequence of debugging the optical power, the wavelength, the bit error rate and the extinction ratio, so that the problem of low efficiency caused by repeated debugging can be avoided.
