Method and system for transmitting optical pulses via dispersive media. # A sequence of optical pulses (1), passes through an optical shaper (2) to give the appropriate form of pulse for the invariant transmission optical channel dispersive ( 3), in which the dominant term dispersion is linear chromatic dispersion, and the pulse sequence reaches a receiver (4), which processes the received signal in the optical domain and / or electric. The pulse shaping remains essentially unaltered as it propagates with a medium whose dominant dispersive component is the chromatic dispersion of second order. # This method avoids introducing elements dispersion compensating second adaptive order in the receiver, transmitting optical pulses whose shape remains essentially unchanged as it propagates through the dispersive optical channel.
