Abstract
In a repeaterless optical fiber transmission system, the invention proposes providing polarization scrambling means. This makes it possible to limit the amount of energy that is transferred by the Raman effect, while increasing the amount of power that can be injected into the link. The invention is equally applicable to the lightwaves used for carrying information and to the lightwaves used for pumping.
