The performance number of readout power meter is in preset range.Again to transmitting optical power calibrate after, by after calibration performance number with
The performance number of BOB equipment actual transmission is compared, and obtains the monitoring precision of transmission power, judges to monitor whether precision is in pre-
If in range, when monitoring precision is not in preset range, the initial value of register is adjusted again, until monitoring precision is in
In preset range, and obtained monitoring precision is reported.
Step S102, computer carry out the survey of eye figure to the BOB equipment for obtaining photoswitch connection permission by eye Diagram Analysis instrument
Examination, obtains eye graph parameter, and simultaneous computer connects the BOB equipment of permission by attenuator with optical line terminal to acquisition photoswitch
The calibration test of progress received optical power, Receiver Precision report test, alert and go the test of alarm calibration test and sensitivity.
Complete transmitting optical power calibration test after, using BOB equipment duplex nature and to BOB equipment into
The feature that needs to wait extinction ratio stable when row eye figure is tested, to be initially completed the BOB equipment of transmitting optical power calibration test into
The test of row eye figure, other three BOB equipment are waited for.During the test using the time for waiting extinction ratio, calculate
Machine carries out the calibration test of received optical power to BOB equipment by attenuator and optical line terminal, Receiver Precision reports test, accuses
Test that is alert and going alarm calibration test and sensitivity.The calibration that computer carries out received optical power while eye figure is tested is surveyed
It is by depositing to acquisition or release that examination, Receiver Precision, which report test, alert and go the test of alarm calibration test and sensitivity,
The control of device is realized.
Optionally, computer carries out the test of eye figure to the BOB equipment for obtaining photoswitch connection permission by eye Diagram Analysis instrument,
It specifically includes:
The eye figure test program of BOB equipment first obtains the control of register, starts to survey the eye figure of BOB equipment
Examination.An initial value is written to the register to one after the control for obtaining register, while discharging the control of register
Power about waits 2 seconds time to stablize extinction ratio after initial value is written in register, and reads the value judgement of extinction ratio
Whether the value of extinction ratio is in preset range.
Here it is divided into two kinds of situations: when extinction ratio is not in preset range, then reads and writes and deposit to computer application again
The permission of device, and repeat the above steps until the extinction ratio obtained is in preset range.According to acquisition in preset range
Extinction ratio judges whether the other parameters of eye figure are in preset range, when the other parameters of eye figure are not in preset range, then
Again to the permission of computer application read-write register, until the other parameters of eye figure are also in preset range, eye figure here

It tests, alert and goes after the completion of the test of alarm calibration test and sensitivity, the photoswitch for discharging current BOB equipment connects power
Limit, is calibrated and is tested to next BOB equipment.
When eye graph parameter is in preset value, and received optical power, Receiver Precision, alerts and alarm, sensitivity is gone to locate
When preset range, then the calibration of current BOB equipment is completed, the data after saving calibration.The light of current BOB equipment is discharged simultaneously
Switch connection permission, next BOB equipment obtain photoswitch and connect permission, carry out calibration test to it.
During carrying out calibration test to a BOB equipment, general eye figure extinction ratio debugging needs 5 times, 10 seconds totally
Left and right, the test of eye figure other parameters probably need 3 seconds, such eye figure part of detecting totally 13 seconds or so；And received optical power one
As calibrate two points, amount to two seconds, Receiver Precision report test two points be also 2 seconds, alarm test is usually 3 seconds or so, is gone
Alarm test needs 2 seconds, and sensitivity test is usually 4 seconds, and the calibration test of receiver totally 13 seconds or so, therefore, use was above-mentioned
Method can complete the calibration test to receiver in the gap of eye figure test, and big for the calibration test for emitting optical power
5 seconds are about needed, therefore, brick method is handed over using above-mentioned BOB equipment, it is only necessary to just complete in the whole of calibration test within 18 seconds or so
Hold.
Above-mentioned BOB equipment calibration method is carrying out the survey of eye figure using the duplex nature and BOB equipment of BOB equipment itself
The feature for needing to wait extinction ratio stable when examination, eye figure test program and receiver calibration test program obtain in turn and discharge meter
The control of register in calculation machine, to utilize light in the gap for carrying out the test of eye figure to BOB equipment using eye Diagram Analysis instrument
Road terminal light source and attenuator carry out calibration test to BOB equipment receiver, to improve the efficiency of BOB equipment Alignment, in turn
Improve the production efficiency of BOB equipment.
It should be understood that the size of the serial number of each step is not meant that the order of the execution order in above-described embodiment, each process
Execution sequence should be determined by its function and internal logic, the implementation process without coping with the embodiment of the present invention constitutes any limit
It is fixed.
Example IV
Referring to fig. 4, a kind of flow diagram of specific BOB equipment calibration method is shown, details are as follows:

Step S209: judging whether the value of extinction ratio meets the requirements, and judge obtain other graph parameters value whether
Within a preset range, when other graph parameters within a preset range when, execute step S211, it is no to then follow the steps S205.
Step S210: judge that the calibration test of received optical power, Receiver Precision report test, alert and alarm calibration gone to survey
Examination tests whether to finish with sensitivity.When each process of receiver is completed, step S211 is executed, is otherwise executed
Step S207.
Step S211: release photoswitch connects permission.Next BOB equipment obtains photoswitch and connects permission, and to its into
Row calibration test.It is worth noting that, it is in step S209 and step S210 that release photoswitch, which connects the condition of permission, here
Test is completed.
Step S212: test data is saved.After the completion of the test of BOB equipment Alignment, needing high-ranking officers, good data are saved.
It is readily comprehensible, during the test, what any one parameter of BOB equipment cannot all be met the requirements after debugging condition is used up
Words, meeting interrupt test are simultaneously quoted mistake, are tested next BOB equipment.
Above-mentioned BOB equipment calibration method is carrying out the survey of eye figure using the duplex nature and BOB equipment of BOB equipment itself
The feature for needing to wait extinction ratio stable when examination, eye figure test program and receiver calibration test program obtain in turn and discharge meter
The control of register in calculation machine, to utilize light in the gap for carrying out the test of eye figure to BOB equipment using eye Diagram Analysis instrument
Road terminal light source and attenuator carry out calibration test to BOB equipment receiver, to improve the efficiency of BOB equipment Alignment, in turn
Improve the production efficiency of BOB equipment.
