This circuit uses the pulse speed control system with central frequency of 50kHs. It takes the feedback to the transmitting audio signals to change the pulses speed. Thus it would drive the LED coupled to the optical fiber. The LED uses General Electric Company's LED55C or other similar LED. The optical transistor at the other end of the optical fiber would receive and decode the light signals to return the audio signals.
