Abstract
The invention relates to a system and a method for transmission over optical fiber () with mode or core scrambling. The system comprises a spatio-temporal encoder () and a plurality of modulators () associated, respectively, with separate propagation modes or cores of said fiber, each modulator modulating a laser beam. Said fiber comprises a plurality of slices (), an amplifier () being provided between any two consecutive slices of the optical fiber. A mode scrambler () is associated with each amplifier in order to perform a permutation of said modes between at least two consecutive slices.
