Experimental study of four-wave miring influence in WDM optical networks

GUAN Ai-hong; ZHANG Qing-hui; FU Hong-liang

The impact of four-wave mixing(FWM) crosstalk on wavelength division multiplexing systems in high nonlinear fiber was studied experimentally.Results showed that the generated wave efficiency decreased with increasing channel spacing and input signal power.The influence of FWM on signal was compared when the channels were arranged equal and unequal.It was shown that 1.5dB larger penalty was introduced in the case of equal channel spacing than in the case of unequal channel spacing.
