The performance number of BOB equipment actual transmissions is compared, and obtains the monitoring precision of transmission power, whether judges to monitor precision 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, the BOB equipment that computer connects permission by eye Diagram Analysis instrument to obtaining photoswitch carry out eye pattern survey
Examination, obtains eye pattern parameter, and simultaneous computer connects the BOB equipment of permission by attenuator with optical line terminal to obtaining 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 luminous power calibration test after, using BOB equipment duplex nature and to BOB equipment into
Row eye pattern test when need wait for extinction ratio stablize the characteristics of, to be initially completed transmitting optical power calibration test BOB equipment into
Row eye pattern is tested, other three BOB equipment are waited for.During the test using the time for waiting for extinction ratio, calculate
Machine is by attenuator and optical line terminal carries out the calibration test of received optical power to BOB equipment, Receiver Precision reports test, accuses
The alert test with going alarm calibration test and sensitivity.The calibration that computer carries out received optical power while eye pattern is tested is surveyed
It is by obtaining or discharging deposit that examination, Receiver Precision, which report test, alert and go to alert calibration test and the test of sensitivity,
The control of device is realized.
Optionally, computer connects the BOB equipment progress eye pattern test of permission by eye Diagram Analysis instrument to obtaining photoswitch,
It specifically includes：
The eye pattern test program of BOB equipment first obtains the control of register, starts to survey the eye pattern of BOB equipment
Examination.An initial value is written, while discharge the control of register to the register to one after the control for obtaining register
Power after initial value is written in register, about waits for the time of 2 seconds to stablize extinction ratio, and the value for reading extinction ratio judges
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 parameter of eye pattern is in preset range, when the other parameter of eye pattern is not in preset range, then
Again to the permission of computer application read-write register, until the other parameter of eye pattern is also in preset range, eye pattern here

When, the permission of read-write register is obtained to computer application, Receiver Precision is carried out to received optical power and reports test, alert and go
Alert calibration test and sensitivity test.
Under normal conditions, it calibrates a received optical power point to take around 1 second, therefore, light work(is received when having calibrated one
During rate point, the program of eye pattern test also does not apply for obtaining the permission of read-write register in the stabilization of waiting delustring ratio, this
When calibration test is completes, received optical power test program is applied and obtains the permission of read-write register again, until connect
The calibration test for receiving luminous power is completed.After the calibration test for completing received optical power, read and write and deposit to computer application again
The permission of device, and then complete to report test to the Receiver Precision of received optical power, alert and go alarm calibration test and sensitivity
Test.
Step S103 is reported to the eye pattern test of current BOB equipment, the calibration test of received optical power, Receiver Precision
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 pattern 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, and preserves the data after calibration.The light of current BOB equipment is discharged simultaneously
Switch connection permission, next BOB equipment obtain photoswitch and connect permission, and calibration test is carried out to it.
During calibration test is carried out to a BOB equipment, general eye pattern extinction ratio debugging needs 5 times, 10 seconds totally
Left and right, the test of eye pattern other parameter probably need 3 seconds, such eye pattern part of detecting totally 13 seconds or so；And received optical power one
As calibrate two points, two seconds altogether, 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 is above-mentioned
Method can complete the calibration test to receiver in the gap of eye pattern test, and big for the calibration test for emitting luminous 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 methods are carrying out eye pattern survey using BOB equipment duplex nature in itself and BOB equipment
The characteristics of needing that extinction ratio is waited for stablize during examination, eye pattern test program and receiver calibration test program obtain and discharge meter in turn
The control of register in calculation machine thus in the gap for carrying out eye pattern test to BOB equipment using eye Diagram Analysis instrument, utilizes light
Road terminal light source and attenuator carry out calibration test to BOB equipment receivers, so as to improve the efficiency of BOB equipment Alignments, and then
Improve the production efficiency of BOB equipment.
It should be understood that the size of the serial number of each step is not meant to the priority of execution sequence, each process in above-described embodiment
Execution sequence should determine that the implementation process without coping with the embodiment of the present invention forms any limit with its function and internal logic
It is fixed.

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 performed, is otherwise performed
Step S207.
Step S211：It discharges photoswitch and connects permission.Next BOB equipment obtains photoswitch and connects permission, and to its into
Row calibration test.It is worth noting that, release photoswitch connects the condition of permission as in step S209 and step S210 here
Test is completed.
Step S212：Preserve test data.After the completion of the test of BOB equipment Alignments, the data for needing high-ranking officers good are preserved.
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 simultaneously quote mistake, next BOB equipment are tested.
Above-mentioned BOB equipment calibration methods are carrying out eye pattern survey using BOB equipment duplex nature in itself and BOB equipment
The characteristics of needing that extinction ratio is waited for stablize during examination, eye pattern test program and receiver calibration test program obtain and discharge meter in turn
The control of register in calculation machine thus in the gap for carrying out eye pattern test to BOB equipment using eye Diagram Analysis instrument, utilizes light
Road terminal light source and attenuator carry out calibration test to BOB equipment receivers, so as to improve the efficiency of BOB equipment Alignments, and then
Improve the production efficiency of BOB equipment.
