摘要
Inserted outside a tilt-correction/control pumping laser (KL) for Raman tilt control, an anti-pumping laser (AL) feeds an anti-pumping signal into a transmission/dispersion-compensating fiber optical wave-guide (FI). The AL has the function of degrading pumping energy in the KL along the FI, so as to limit the FI's effective length and facilitate quick tilt adjustment. An independent claim is also included for a system for quick adjustment in the tilt of a wavelength multiplex signal through pumping lasers that feed their pumping signals into fiber optical wave-guides.
