Verfahren zum Reduzieren von Kreuzphasenmodulation-induzierter Intensitätsverzerrung in einem optischen WDM Übertragungssystem

摘要

The cross phase modulation distortion reduction technique has an optical line (7) with several sections (TF) of fibre optics and a repeater (9). A time difference is introduced between consecutive repeater channels. the difference is chosen to be above zero and less than that which would lose the correlation between contributions.
