ABSTRACT:
An anti-pump laser (AL) is used in addition to a tilt correction pumplaser (KL) for Raman tilt control, said anti-pump laser injecting an anti-pump signal into a transmission fiber (FI) or a dispersion compensation fiber (DCF). The anti-pump laser (AL) has the function of reducing the pump energy of the control pump laser (KL) in the course of the fiber (FI, DCF), in order to restrict its effective length and to enable a faster adjustment of the tilt.
