Abstract

A predistortion circuit that cancels second order distortion of light emitting diodes enabling interference free transmission of multiple vestigial sideband television channels through a single optical fiber. This is achieved by preamplifying a signal with an amplifier that has opposite characteristics to the distortions of a light emitting diode.
