Fig. 1 is a flowchart illustrating steps of an embodiment of a method for debugging a transmitting end of a DWDM optical module according to the present application.
Referring to fig. 1, a method for debugging a transmitting end of a DWDM optical module may include the following steps:
s100, receiving an initial value of the extinction ratio and an initial value of the error rate of the transmitting end, and debugging the optical power of the transmitting end according to a preset optical power debugging rule to generate 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 debug engineer. For example, the extinction ratio is denoted as moddebugadc, the initial value of the moddebugadc is set to x5F (x in x5F represents hexadecimal), the set initial value of the extinction ratio is smaller than the extinction ratio target value to be debugged, and if the target value of the extinction ratio is set to x8F, the debugging engineer only needs to set the initial value of the extinction ratio to be smaller than x 8F. In the same way, the error rate is marked as EA_bias, the initial value of EA_bias is set as x400, and the initial value of the error rate can cause transmission failure and the like when the transmitting end transmits light, thereby being convenient for debugging the error rate in the subsequent steps. The initial value of the extinction ratio is smaller than the extinction ratio target value to be debugged, and transmission failure and other conditions occur at the transmitting end, so that when the extinction ratio and the bit error rate are balanced, the purpose is to ensure that the extinction ratio or the bit error rate only needs to be debugged in the direction of increasing when the extinction ratio or the bit error rate is debugged, and the problem that repeated debugging is needed is avoided. In other embodiments, the initial value of the extinction ratio and the initial value of the error rate may be set according to actual situations, so long as the purpose of debugging in one direction can be achieved, and the application does not limit the initial value of the extinction ratio and the initial value of the error rate.
In some embodiments, the optical power debug information includes optical power debug pass and optical power debug fail. The debug engineer sets the initial value of the collection point, for example, the initial value of the collection point may be set to 30, and the transmitting end debug system obtains the optical power matched with the collection point according to the initial value of the collection point, where the value of the optical power is related to the collection point, and each collection point corresponds to one optical power. And then, if the optical power corresponding to the acquisition point updated by the step length of the acquisition point at each time is within the preset optical power target range, detecting whether the optical power corresponding to the acquisition point updated by the step length of the acquisition point is within the preset optical power target range or not. If the transmitting end debugging system detects that the value of the optical power is within the preset optical power target range, generating optical power to be debugged to be qualified, otherwise, proving that an abnormal condition occurs in the transmitting end, and generating a debugging failure result by the transmitting end debugging system, and ending the debugging. In this embodiment, the preset optical power target range may be set between 2dbm and 4dbm, the acquisition point step size may be set to 2, the preset acquisition point update frequency may be set to 30, and in other embodiments, the values of the preset optical power target range, the acquisition point step size and the preset acquisition point update frequency may be set according to the actual situation, and meanwhile, the application does not limit the initial value of the acquisition point.
In some embodiments, the debug engineer may also set initial values of two collection points, respectively denoted as a first initial collection point and a second initial collection point, set the first initial collection point as 30, set the second initial collection point as 80, and then obtain a first initial optical power matched with the first initial collection point and a second initial optical power matched with the second initial collection point, respectively, and if the first initial optical power is at the left side of the preset optical power target range, i.e. the first initial optical power is less than 2dbm, and the second initial optical power is greater than 4dbm, a dichotomy may be used, i.e. an average value of the first initial collection point and the second initial collection point is obtained, and denoted as a third initial collection point. Then, a third initial optical power matched with the third initial acquisition point is obtained, and then, according to comparison between the third initial optical power and a preset optical power target range, next step debugging is performed, which is not described herein.
And S200, if the optical power debugging information is qualified for optical power debugging, 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 debug information includes wavelength debug pass and wavelength debug fail. After the optical power is qualified, because the wavelength and the optical power can be mutually influenced, the wavelength needs to be further debugged, so that the equilibrium state between the wavelength and the optical power is achieved.
In some embodiments, after the wavelength of the transmitting end is tuned by the tuning engineer, the temperature of the TEC (i.e. the semiconductor refrigerator) inside the transmitting end may be changed, thereby affecting the optical power tuned by the above steps. Therefore, the wavelength of the transmitting end needs to be first debugged, and the steps are as follows:
a1. and acquiring a temperature value of the transmitting end. And obtaining a wavelength debugging value based on the temperature value of the transmitting end and a preset conversion reference value. The transmitting end debugging system reads the temperature value matched with the acquisition points in the step S100 in the semiconductor refrigerator, wherein each acquisition point also corresponds to one temperature value. For example, the temperature value of the transmitting end read by the transmitting end debugging system is 25 ℃. In this embodiment, the preset switching reference value is set to 0.09 nm/. Degree.C. And (3) 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 the actual situation.
a2. And obtaining a wavelength target range based on the target wavelength and the wavelength debugging value. In this example, the target wavelength is 1529.55nm, and the wavelength target range [1527.25nm to 1531.8nm ] is obtained based on the target wavelength 1529.55nm and the wavelength tuning value of 2.25nm. In other embodiments, the wavelength tuning value may be set to a value less than 2.25nm and greater than 0nm, for example, the wavelength tuning value is set to 0.04nm, the obtained wavelength target range is [1529.53nm to 1529.57nm ], and the target wavelength may be set according to practical situations.
a3. Updating the wavelength of the transmitting end based on the wavelength step length, detecting whether the updated wavelength is in a wavelength target range after updating the wavelength by the wavelength step length every time, and generating qualified wavelength debugging if the wavelength is detected to be in the wavelength target range; 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, and the wavelength is updated with the wavelength step of 0.1nm each time, for example, the value of the wavelength before being updated obtained by the transmitting end debugging system is 1528.5nm, and after the wavelength is updated with the wavelength step of 0.1nm for the sixth time, the wavelength at this time reaches the wavelength target range [1527.25 nm-1531.8 nm ], so as to generate the qualified wavelength debugging. Meanwhile, the debug engineer may set the preset wavelength update times, for example, the preset wavelength update times is 10, if the wavelength is updated 10 times with the wavelength step length of 0.1nm, the updated wavelength does not reach the wavelength target range [1527.25 nm-1531.8 nm ], and the wavelength debug failure is generated. In other embodiments, the wavelength step may 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.
In some embodiments, if the updated wavelength has not reached the wavelength target range [1529.1 nm-1530 nm ], the debug engineer may modify the TEC temperature inside the transmitting end again, and then repeat steps a1-a3 to determine whether the debugged wavelength has reached the wavelength target range [1529.1 nm-1530 nm ], and if the debugged wavelength has not reached the wavelength target range [1529.1 nm-1530 nm ], generate wavelength debug failure information.
In some embodiments, if the wavelength debug information is qualified for wavelength debug, but the optical power is changed due to the wavelength change, so that the transmitting end debug system fails to generate optical power debug, the optical power needs to be debugged again, that is, the optical power resetting step is performed. The steps of the optical power resetting are as follows:
b1. a first acquisition point and a second acquisition point are acquired. In this embodiment, the initial value of the acquisition point is updated with the acquisition point step length, the acquisition point updated with the acquisition point step length for the first time is recorded as a first acquisition point, and the acquisition point updated with the acquisition point step length for the second time is recorded as a second acquisition point. In other embodiments, the acquisition point updated with the acquisition point step size for the mth time may be denoted as the first acquisition point, and the acquisition point updated with the acquisition point step size for the mth+i time may be denoted as the 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 first coordinate points; and acquiring a 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 debugging system obtains the second optical power matched with the first acquisition point 32, for example, the second optical power is 8dbm, and the first coordinate point is (32,8). Similarly, the transmitting-end debugging system obtains the 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 the present embodiment, the absolute value of the quotient between the difference of the third optical power and the second optical power and the difference of the second acquisition point and the first acquisition point is recorded as an optical power slope value, and then | (36-32)/(12-8) |=1, at which time 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 with the reciprocal of the optical power slope value as the step size based on the optical power slope value 1. In step S100, the preset optical power target range is [2 dbm-4 dbm ], and the reciprocal of the optical power slope value is required to be used as the step to reduce the value of the third optical power. 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 in steps of the inverse of the value of the optical power slope.
b5. Detecting whether the updated third optical power is within a preset optical power target range, and if so, generating optical power to be qualified in debugging. In this embodiment, the debug engineer may set the preset optical power update times, for example, set the preset optical power update times to 6 times, if the third optical power is updated by taking the reciprocal of the optical power slope value as the step length, and the updated third optical power is within [2dbm to 4dbm ] when the third optical power is updated 6 times or less than 6 times, the transmitting end debug system generates the optical power to debug qualified, and the optical power resetting procedure is completed. If the reciprocal of the optical power slope value is taken as a step length, the updated third optical power is larger than 6 times, the updated third optical power is not in the range of [2 dbm-4 dbm ], the acquisition point matched with the third optical power updated last time is smaller than the preset acquisition point limit value, and the acquisition point matched with the third optical power updated last time is recorded as a first complex modulation acquisition point. Then, the debugging engineer can update the first multi-modulation acquisition point with the acquisition point step length again and within the preset acquisition point updating times, and after updating the first multi-modulation acquisition point with the acquisition point step length each time, the complex light modulation power matched with the updated first multi-modulation acquisition point is obtained, the transmitting end debugging system detects whether the complex light modulation power is within [2 dbm-4 dbm ], and if the transmitting end debugging system detects that the complex light modulation power is within [2 dbm-4 dbm ], the optical power is generated to be qualified in debugging. If the transmitting end debugging system detects that the complex dimming power is not within [2 dbm-4 dbm ] or the updated first complex dimming acquisition point is larger than the preset acquisition point limit value, the transmitting end debugging system fails to generate the optical power for debugging, and the optical power complex dimming program is ended. The preset collection point limit value may be set to 255, and in other embodiments, the preset collection point limit value may be set according to an actual situation, which is not limited in the present application.
S300, if the wavelength debugging information is qualified in wavelength debugging, the initial value of the error rate is debugged according to a preset error rate debugging rule, and error rate debugging information is generated.
In some embodiments, the bit error rate debug information includes bit error rate debug pass and bit error rate debug 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 bit error rate ea_bias is x400, the bit error rate step is x80, and the ea_bias can be increased by the bit error rate step x80 to obtain the first bit error rate x480. In other embodiments, the value of the bit error rate step may be set according to the actual situation, which is not limited in the present application. In order to improve the debugging efficiency, the debugging engineer may set the number of bit error rate updates according to the actual situation, for example, set the number of bit error rate updates to 3, and update the initial value of the bit error rate with the bit error rate step x80 each time, to obtain the first bit error rate. The transmitting end debugging system detects whether the first bit error rate is within a preset bit error rate target range, and if the number of times of updating the initial value of the bit error rate with the bit error rate step length x80 is less than or equal to 3, the transmitting end debugging system detects that the first bit error rate is within the preset bit error rate target range, and generates that the bit error rate is qualified for debugging; if the number of times of updating the initial value of the bit error rate by the bit error rate step size x80 is more than 3, the transmitting end debugging system detects that the first bit error rate is not in the preset bit error rate target range, and generates bit error rate debugging failure. In other embodiments, the number of bit error rate updates may be set to 5, and the value of the number of bit error rate updates is not limited in the present application.
And S400, if the error rate debugging information is qualified for error rate debugging, updating the initial value of the extinction ratio by using a preset extinction ratio updating rule to obtain a first extinction ratio.
In some embodiments, the initial value of extinction ratio is updated with an extinction ratio step size, and it is detected whether the number of updates of the extinction ratio step size is equal to N, where N is an integer greater than 1. In this embodiment, the initial value of the extinction ratio moddebug_adc is x5F, and the extinction ratio step size 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 taken as the first extinction ratio. And taking the result of updating the initial value of the extinction ratio by the extinction ratio step size for the nth 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 value such as 8, and the value of N is not limited in this application. The first extinction ratio is x73 by taking the result of updating the initial value of the extinction ratio by the extinction ratio step size at the 4 th time as the first extinction ratio. The second extinction ratio is x78, with the result of updating the initial value of the extinction ratio by the extinction ratio step size at the 5 th time being the second extinction ratio. And then, the transmitting end debugging system detects whether the second extinction ratio is in a preset extinction ratio target range, and if the second extinction ratio is detected not to be in the preset extinction ratio target range, the first error rate is updated based on the error rate step length, so that the second error rate is obtained. In this embodiment, the first bit error rate is updated with the bit error rate step x80, and the preset extinction ratio target range is [ x5F-xFF ], and in other embodiments, the preset extinction ratio target range may be other ranges. Then, the transmitting end debugging system obtains the extinction ratio matched with the second error rate and marks the extinction ratio as a third extinction ratio. And finally, the transmitting end 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 bit error rate is less than the preset bit error rate limit, the second bit error rate is updated based on the bit error rate step size. If the updated second error rate is greater than or equal to the preset error rate limit value, the transmitting end debugging system generates a debugging failure result. In this embodiment, the preset error rate limit value is xFFF, and in other embodiments, the preset error rate limit value may be set according to actual requirements. 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 debugged to be qualified, but the extinction ratio is changed, so that the transmitting end debugging system detects that the error rate debugging information is the error rate debugging failure aiming at the debugged qualified error rate, and the error rate is required to be debugged again, namely, the error rate resetting step is performed. The error rate resetting step is as follows:
c1. updating the first error rate based on the error rate step size, and updating the initial value of the extinction ratio based on the extinction ratio step size.
c2. The transmitting end debugging system detects whether the updated extinction ratio is in a preset extinction ratio target range, and if the updated extinction ratio is detected to be in the preset extinction ratio target range, detects whether the updated bit error rate is in the preset bit error rate target range. If the updated bit error rate is detected to be within the preset bit error rate target range, generating that the bit error rate is qualified in debugging, and ending the bit error rate resetting. In this embodiment, the first bit error rate is increased by the bit error rate step x80, where the first bit error rate is x480, and the extinction ratio is reduced by the extinction ratio step x5 by 2 times to obtain the updated extinction ratio which is x56, and recorded as a fourth extinction ratio which is x56. In other embodiments, the first error rate may be reduced by the error rate step size x80 or the initial value of the extinction ratio may be increased by the extinction ratio step size x5 2 times or more, which is not limited in the update manner of the initial value of the first error rate and the extinction ratio.
c21. If the transmitting end debugging system detects that the updated extinction ratio is not in the preset extinction ratio target range, the updated first error rate is increased, and then whether the extinction ratio matched with the updated first error rate is in the preset extinction ratio target range is judged. 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 the actual situation, for example, may be set to 3 times or 5 times. After the first error rate is increased each time, the extinction ratio matched with the first error rate after each update is obtained, and whether the extinction ratio is in a preset extinction ratio target range or not is detected. 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 is debugged to be qualified, and the error rate resetting 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 transmitting end debugging system needs to return to the step c1 for debugging again, and the application is not repeated here.
c22. In step c21, if the extinction ratio matched with the increased first error rate is not within the preset extinction ratio target range, the transmitting end debugging system needs to determine whether the updated first error rate is less than or equal to the preset error rate limit value. If the first error rate at this time is smaller than the preset error rate limit value, the first error rate at this time needs to be continuously increased, and then the process returns to the step c21 again for re-judgment, which is not repeated here. If the first bit error rate is larger than or equal to the preset bit error rate limit value, generating bit error rate debugging failure and ending bit error rate resetting.
S500, detecting whether the first extinction ratio is in a preset extinction ratio target range, and if so, generating a debugging qualified result.
The method for debugging the transmitting end of the DWDM optical module of the embodiment first sets an initial value of extinction ratio of the transmitting end, so that the extinction ratio of the transmitting end is smaller than a target value of extinction ratio for debugging, and sets an initial value of error rate, so that transmission of the transmitting end is poor, a debugging direction of extinction ratio and error rate is determined, only debugging is needed in a direction of increasing extinction ratio or error rate, and debugging duration is reduced. Then, the transmitting end 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. Finally, when the first debugging of the extinction ratio or the optical power fails, the extinction ratio and the optical power need to be re-subjected to re-debugging, and the debugging information of the extinction ratio and the optical power is confirmed again.
