| Abstract: | It studies the effect of the noise induced by the instantaneous pump power deletion on the system performance(such as eye diagram and bit error rate) of optical fiber DWDM transmission systems.Comparison is given to the degree of the effect for different channel number and bit rate.Simulation results are presented.The performance degradation induced by this kind of noise and induced by the Raman crosstalk is also compared.Analysis is performed on the magnitude of this kind of noise and its relation to the bit pattern.It is concluded that RZ waveform can tolerate the noise better. |
