This circuit uses center frequency 50kHz impulse speed modulation system. Audio frequency feedback transmitter can change impluse speed, and it isused to drivethe LEDcoupled to optical fiber. LED uses General Electric LED 5C or similar LED. Optical transistor islocated on another end of optical fiber toreceive and demodulate light signal and make audio frequency recover.
