摘    要:本文在分析了均匀掺杂分布式掺饵光纤放大器的基础上,提出了沿传输方向掺杂浓度线性单调下降(单变),和线性降升结合(两变)的两种渐变型分布式掺饵光纤放大器,并用传输方程研究和比较了透明传输和最佳掺杂浓度下,均匀、单变和两变型三种放大器中的信号和噪音的传输特性及放大器的噪音指数、信噪比、临界泵浦功能和最佳泵浦周期等特性.

关 键 词:分布式掺铒光纤放大器  渐变型  噪音  临界泵浦功率  泵周期

Abstract:Based on analyzing distributed erbium doped fiber amplifier (d-EDFA) of evenly doped density along propagating direction, we put forward two sort d - EDFAs of slowly and linearly variously doped density along propagating direction: one - variation and two - variation d - EDFA, and by using convective equations study the propagating properties of signal and noise in three sort d - EDFAs, noise figure, signal - noise ratio, necessary pump and optimal pump period, under both transparent transmission and optimal doped density.
Keywords:d-EDFA  Slowly variously doped density  Noise  Necessary pump  Pump period
