APD avalanche photodiode driver
Optical signal receiving transmission and transmission signal This module converts the optical signal received by the avalanche photodiode into an electrical signal for processing.
Realize the photoelectric conversion by realizing various types of waveform signals transmitted by light. With the optical signal transmission module of the store, optical communication of signals can be realized.
On the left, the signal generator inputs 7KHz to the transmitting module. The 2Vpp sine wave signal is converted into the right oscilloscope by the electro-optical-photoelectric conversion of the two modules. The frequency is 7.143KHz.
On the left, the signal generator inputs 1MHz to the transmitting module. The 2Vpp sine wave signal is converted into the right oscilloscope by the electro-optical-photoelectric conversion of the two modules. The frequency is 985.2KHz.
