Abstract
An input signal provided by a generator is applied to a laser emitting diode via a predistortion circuit for improving the linearity of the response of the source. The predistortion circuit includes a linear pi attenuator member constituted by resistances and a non-linear compensating element constituted by a Schottky diode connected in parallel with said attenuator member. The invention is particularly applicable to making light transmitting cable heads for optical fiber telecommunications systems.
