Abstract

The invention concerns a wavelength-division multiplexing optical transmission system comprising transmission means, reception means and an optical transmission line whereon is distributed a plurality of amplifiers, the transmission means including means for generating control over-modulations and pre-emphasis means The invention is characterised in that the transmission means comprise means for scrambling the signal transmitted on a specific frequency band and the frequencies of the control over-modulations are included in said band.
