| Abstract: | In this paper propagation equations for analyzing bidirectional amplification in erbium-doped fiber amplifiers(EDFA)are established.The variation of erbium fiber length and pumping power on gain and noise figure is analyzed in terms of numerical simulation calculation.The characteristic curve of gain and noise figure vs bidirectional input signal power is given.The satisfactory results are obtained. |
