【Abstract】 The black box model for an erbium doped amplifer was derived from the two level amplified model. Different methods to compute the input signal gain were given according to the relative working modes of EDFA’s. When there are six WDM optical input signals, using the black box model it simulated the amplified optical spectrum and compared them with experiment results. They agree with each other very well.更多还原
