摘要

文章从密集波分复用（DWDM）系统抵抗恶意侵扰的角度

分析了光放大段（OAS）中掺铒光纤放大器（EDFA）和OAS长度的配置对系统稳定性的影响

认为EDFA累积噪声会随着放大器的级数增加而呈线性增长

而且还会随着OAS损耗的增大而呈指数增长。系统的OAS数量和接收机灵敏度确定时

选择恰当的EDFA配置和OAS长度

可以达到提高系统稳定性的效果。

Abstract

In view of the robustness of the DWDM system against malicious attacks

the effects of the allocation of EDFAs and the length of Optical Amplifier Sections（OAS） on the system stability are analyzed.It is found that the accumulated noise of the amplifiers increases linearly with their stage numbers and exponentially with their losses.When the number of OAS and the receiver sensitivity of a system are fixed

it will enhance the stability of the system to choose a proper EDFA allocation and OAS length.
