A method and apparatus are described for stabilizing optical signals that are generated by an LED and are converted into a voltage in a receiver, by returning a voltage signal derived from the receiver to the voltage supply of the LED, with the voltage signal being compared with a reference voltage, wherein when the returned voltage is lower than the reference voltage, the LED input voltage is increased and, conversely, when the returned voltage is greater than the reference voltage, the LED input voltage is decreased.
