摘要
从掺铒光纤放大器的能级速率方程和光传输方程出发，得到一个简单的表达式，可用来计算放大器的增益、噪声系数等。在放大器的非饱和范围内，计算结果和实验结果十分一致。
A simple expression deduced from EDFA (Erbium-Doped Fiber Amplifier) rate equations and light propagation equations is presented in this paper.Using the expression,gain and NF(Noise Figure) of amplifiers can be calculated.The simulated calculations are in good agreement with experimental results before the amplifiers are saturated.
