SUPPRESSION OF THE BRILLOUIN EFFECT BY AMPLITUDE MODULATION AND POLARIZATION INTERFERENCE

摘要

The invention proposes, in a fiber optic transmission system without repeaters, to provide amplitude modulation means, associated with polarization scrambling means. It thus makes it possible to limit the power backscattered by the Brillouin effect, or to increase the power injected into the link. The invention applies both for light waves carrying information and for pump light waves.
