摘　　要：从光放大器面对的两种隐蔽降质攻击方式出发,介绍了基于色散补偿光纤(DCF)的WDM系统的优化方案,得到了DCF的最佳色散补偿效率和最佳敷设位置,最后通过仿真实验比较了原系统和两种改进系统抵御隐蔽降质攻击的效果,得到了抵御降质攻击的最佳WDM系统配置。Aiming at two kinds of covert QoS attack faced for optical amplifier, the optimized scheme for WDM system based on dispersion compensation fiber （DCF） is introduced, and the optimum dispersion compensation efficiency and optimum installation positions are obtained. Finally the effects for original system and improved system to prevent covert QoS attacks are compared through simulation experiments, and the optimum WDM system configuration for preventing QoS attacks is obtained.
