Recommended applications
A 5:95 beam splitter is connected to the back end of the multimode VOA, where the 5% port output is connected to the multimode PD as the monitoring end, and the 95% port outputs directly as the output end.
The data is reversed through the monitoring end to control the output voltage so that the output end reaches the set attenuation value.
Test block diagram
Test Data - - - Attenuation Accuracy
1. The horizontal axis is the attenuation value.
2. The vertical axis is the difference between the attenuation value calculated by the monitoring end and the actual attenuation value of the output end.
Recommended power supply conditions
1. Continuous square wave drive, frequency: 5KHZ, waveform: square wave
2. Peak-to-peak value: 0-35V, duty cycle: 50%
