Abstract
The invention concerns a method for the amplification of wavelength division multiplex (WDM) signals in a WDM transmission system, pump light being injected into an optical waveguide of the optical transmission system contrary to the transmission direction of the WDM signals, the pump light being designed so that at least one WDM signal is individually amplified by a stimulated Brillouin scattering process in the optical waveguide produced by the pump light, as well as an optical amplifier, an optical broadband amplifier system and a WDM transmission system for it.
