︱x-y︱≤2dbm
If after substituting into all y and x corresponding with it, above-mentioned judgment formula is all set up, then calibration is passed through; Otherwise, calibrate unsuccessfully.After operation like this, foundation accurately can be provided for follow-up eye pattern test b OB function admirable, while avoiding occurring BOB defective products, significantly improve the quality of production, and then improve the reputation of manufacturer.
For understanding calibration process of the present invention better, be described with an example below.
The integrality of confirmation system optical fiber cable, and the received optical power value verifying optical attenuator, the received optical power value obtained is respectively-27.1 ,-15.9 ,-8.7 ,-24.2 ,-9.6, is in the scope of-28 ~-8, meets alignment requirements.
Set gradually the emission wavelength of optical attenuator, luminous POW pattern and APMABS pattern, and open the optical transport of optical attenuator, then detect and operate the need of to voltage, if find in calibration process to need to reduce voltage, then first carry out voltage reducing operation, then start calibration.
By received optical power value RxPower
1=-27.1 luminous gears arranging optical line terminal, read corresponding BOB module received power value x in real time
1=197; By received optical power value RxPower
2=-15.9 luminous gears arranging optical line terminal, read corresponding BOB module received power value x in real time
2=2272; By received optical power value RxPower
3=-8.7 luminous gears arranging optical line terminal, read corresponding BOB module received power value x in real time
3=9152.
After being converted to uW by-27.1 ,-15.9 ,-8.7 from dbm, be respectively 1.95,25.70,134.90.If: 197
2-2272
2=H, 2272
2-9152
2=J, 197-2272=K, 2272-9152=L, 1.95-25.70=F, 25.70-134.90=G, and by formula RxPower=slope_P2 × x
2+ slope_P1 × x+offset converts, then, after substituting into data, obtain following result:
slope_P1=（F×J-G×H）/（K×J-L×H）
=0.010228233024114434；
slope_P2=（F×L-G×K）/（H×L-J×K）
=4.93937783287344e-7；
Due to offset=slope_P2 × x
1 2+ slope_P1 × x
1-RxPower
1, therefore, after substituting into the value of slope_P1 and slope_P2, finally obtain offset=-0.08428653742409642.
So RxPowerSlopeP2, RxPowerSlopeP1 and RxPowerOffset are calculated by following formula:
RxPowerSlopeP2=（4.93937783287344e-7/0.1）×2
30=838；
RxPowerSlopeP1=（0.010228233024114434/0.1）×2
13=5304；
RxPowerOffset=（-0.08428653742409642/0.1）×2
12=-3452。
RxPowerSlopeP2, RxPowerSlopeP1 and RxPowerOffset(of obtaining are 16-bit Interger type data) be split as 2 8-bit(most-significant byte MSB, least-significant byte LSB) after, obtain 3,70,20,184,242,132 respectively, then write in the register of BOB module, then carry out the verification of BOB module transmitting optical power.
Choose arbitrarily two continuous print transmitting optical power values after BOB module check-24.2 and-9.6, be in the scope of-28 ~-8, meet alignment requirements, then according to transmitting optical power value-24.2 after verification, the luminous gear of optical line terminal is set, and read the received power value 3.7(uW of BOB module in real time), change, obtain-24.317982759330046(dbm), then itself and the difference verifying transmitting optical power-24.2 is calculated, take absolute value again, obtain 0.11798275933004731.
According to transmitting optical power value-9.6 after verification, the luminous gear of optical line terminal is set, and read the received power value 107.5(uW of BOB module in real time), change, obtain-9.685915357483757(dbm), then calculate itself and the difference verifying transmitting optical power-9.6, then take absolute value, obtain 0.08591535748375811.
Because 0.11798275933004731 and 0.08591535748375811 is all less than 2, therefore, the calibration for this BOB module received power is passed through.
The control technology of the existing maturation of Appropriate application of the present invention and equipment, and pass through effective combination of software and hardware, have devised a kind of test macro for BOB, thus the automatic calibration achieved BOB module received power, solve and calibrate trouble, complex operation, problem that calibration accuracy is low in the past.Compared with prior art, technological progress is fairly obvious in the present invention, has outstanding substantive distinguishing features and significant progress.
