摘　　要：传统光传输系统设计多针对低速率传输系统,单一采用光功率分配预算即可满足系统设计要求。随着光传输速率和光通信容量的不断增加,高速光传输系统受色散影响严重,传统方法无法满足系统可靠性和有效性的要求,需要对系统色散进行补偿。针对系统大容量高速率的需求设计,采取DWDM光传输系统总体设计方案,提出了一种基于光功率分配、传输误码率、系统上升时间和线路色散预算的综合性能评价方法,分析了系统受各种因素的影响,通过系统参数优化选取与仿真设计,给出了系统仿真评估结果。Traditional optical transmission system design for low-rate transmission system, a single optical pow- er to allocate budgets to meet system design requirements. With the increase of optical transmission capacity and optical communications rate, high-speed optical transmission systems is affected by dispersion seriously. Traditional methods can not meet the requirements of the reliability and effectiveness of the system and dispersion compensation is needed. Aiming at DWDM systems design,put forward a kind of comprehensive performance evaluating method which is based on the optical power distribution, BER of the system transmission,the system rise time and dispersion budget of optic line, analyzed the impact of the system affected by various fac- tors. Then, through the system parameters calculation, optimization selection and simulation design, gave the system simulation and evaluation results.
