| 摘 要： | 建立了考虑ＡＳＥ谱和背景损耗影响的双向掺铒光纤放大器（ＢｉＥＤＦＡ）稳态放大速率方程模型，分析了增益与掺铒光纤长度、输入信号光功率、泵浦光功率及泵浦方式等结构参数之间的关系，研究了单向和双向等功率泵浦下正反向噪声系数随正反向信号光输入功率的变化行为，所得结果可作为ＢｉＥＤＦＡ优化设计的理论依据

| Abstract: | The rate equation model is setup for the signal gain, pump absorption and output noise spectrum of bidirectional EDFA (Bi EDFA) including numbers of signals, pumps of arbitrary direction, amplified spontaneous emission (ASE) and inherent loss. The influence of erbium doped fiber length, input signal power, pump style and pump power on the gain characteristics of Bi EDFA is analyzed. Forward and backward noise figure for different pump style versus bidirectional input signal power is investigated. |
