The coupling circuit with optical fiber transmission data
The circuit shown in figure can convert input analog signal into frequency signal by voltage V / F - the frequency converter, then it is sent to the optical fiber by light emitting diode. The length of optical fiber or polystyrene is determined the isolated voltage between the digital or analog signal input terminal and a photodiode. The photodiode can drive operational amplifier A1 with 100mA output.
