Abstract
In accordance with the present invention, an optical fiber communications system is provided with an adaptive data equalizer to correct for linear disortion of signals transmitted over optical fibers. A feedback signal from a receiver is used to custom tailor the spectral profile of a launched pulse to thereby minimize the distortion of a received pulse. The system uses optical taps for feedback control in order to adapt to changing conditions in the fiber path.
