An optical communication link with correction of non-linear effects comprises an optical fiber transmission line subject to chromatic dispersion and non-linear effects and correction means for limiting the disadvantageous consequences of this dispersion and/or these non-linear effects. The correction means comprise at the output of the transmission line a dispersion compensator adapted to apply dispersion in the opposite direction to and of lower absolute value than the dispersion due to the transmission line.

Optical communication link with correction of non-linear effects and

In a long-haul optical communication line the fibers to be made into the line are grouped into pairs such that the two fibers in each pair have substantially symmetrical chromatic dispersion relative to a mean value of the chromatic dispersion of all the fibers of the line. These two fibers are thereafter connected consecutively into the line. The invention finds an application in telecommunications.
