Abstract
A system and method for transmission of data modulated spectrally enriched optical pulses via an error free propagation region of an optical fiber, in which the optical pulses generated by an optical transmitter have a spectrum that is substantially wider than the spectrum of Fourier-transform limit at an input of the error-free propagation region. The spectral width of the optical pulses gradually narrows while transmitting along this region and becomes comparable to the Fourier-transform limit at an output of this region. Linear and non-linear distortions are compensated within the error free propagation region respectively by deployment of dispersion compensating units and phase modulation of transmitted optical pulses for providing them with an appropriate frequency chirp having shape comparable with a frequency chirp induced by a self-phase modulation of the optical fiber but having opposite sign.
