optical amplification and dispersion management have become important factors in fiber-optic communication systems.Specifically
in the gradual replacement of 10Gbit/s fiber-optic communication systems by 40Gbit/s systems
still higher requirements are placed on nonlinear resistance and dispersion management by communication systems.In this paper
three dispersion management schemes are compared and the effects of the input optical power in different schemes on the Qvalue
BER and SNR of 40Gbit/s fiber-optic communication systems discussed.It is found that the dispersion compensation scheme with mid-amplification has better Qvalue and SNR and is more suitable for ultra-long fiber-optic communication systems.
