ABSTRACT:
A system and method for transmitting data modulated spectrally enriched optical pulses with a frequency chirp via an error free propagation region of an optical fiber, in which spectrum of optical pulses gradually depletes from the spectrum that is substantially wider than the spectrum of Fourier-transform limit at an input of the error-free propagation region and becomes comparable to the Fourier-transform limit at an output of this region. The gradual depletion of the spectrum is achieved by utilizing a frequency chirp converter having a dispersion sign opposite to a dispersion sign of the optical fiber.
