Abstract
The invention relates to a system and a method for transmission over optical fiber (130) with mode or core scrambling. The system comprises a spatio-temporal encoder (110) and a plurality of modulators (1251, . . . , 125n) associated, respectively, with separate propagation modes or cores of said fiber, each modulator modulating a laser beam. Said fiber comprises a plurality of slices (1301, . . . , 130L), an amplifier (140l) being provided between any two consecutive slices of the optical fiber. A mode scrambler (150l) is associated with each amplifier in order to perform a permutation of said modes between at least two consecutive slices.
