摘要
A pumping source is provided for the Raman amplification of an optical wavelength division multiplex signal, wherein the pumping source has a number of pumping lasers with, in each case, different pumping wavelengths. Modules for the angle and/or amplitude modulation of pumping signals of the pumping lasers are connected to the pumping lasers, such that by appropriate adaptation of the modulation of the pumping signals mixing products from four-wave mixing between the pumping signals are suppressed.
