本文所建立的EDFA的理论模型考虑了ASE和光纤的本征衰耗,修改了速率方程和传输方程。对泵浦光功率、信号光功率沿光纤长度的分布及EDFA增益特性等进行了数值解,所得结果与实验结果符合较好。
The theoretical model of EDFA established in this paper considers the intrinsic attenuation of ASE and fiber and modifies the rate equation and transmission equation. The pump power, signal power along the fiber length distribution and EDFA gain characteristics of the numerical solution, the results obtained and the experimental results in good.
