Abstract
The authors analyzed the factors which affect the output OSNR (Optical Signal-to-Noise Ratio) according to the expressions of OSNR and equivalent noise figure of DWDM system using cascade EDFAs.The reasons of difference in output OSNR between the channels were also discussed in this paper.
