Optical fiber medium transformer controller and control signal remote transmission method

The invention provides an optical fiber medium transformer controller and a control signal remote transmission method. The optical fiber medium transformer controller comprises an on-load tap-changer gear controller; the electric mechanism box is in communication connection with the on-load tap-changer gear controller; the on-load tap-changer gear controller comprises a PWM (Pulse Width Modulation) modulation module, which is configured to convert a control signal sent to the electric mechanism box into a PWM signal; the optical fiber sending module is in communication connection with the PWM modulation module and is configured to convert the PWM signal into an optical signal and send the optical signal; the electric mechanism box comprises an optical fiber receiving module which is in communication connection with an optical fiber sending module and is configured to receive an optical signal sent by the optical fiber sending module, convert the optical signal back to a PWM signal and restore the PWM signal t
