摘要
对OCDMA系统性能与光源占空比的关系进行了理论分析,提出了分析等效相移超结构光纤光栅编解码器的结构参数与光源脉冲宽度关系的定量分析方法,利用MATLAB仿真软件计算分析了光源占空比对编解码器性能的影响。计算分析表明:光源占空比直接影响到编解码性能。考虑到窄脉宽光源高昂成本的因素,提出了在低成本高占空比的情形下的改进设想。
In the paper, the relationship between source duty ratio and performance of OCDMA system was investigated and simulated based on MATLAB.A method of quantitative analysis of the relationship between EPS-SSFBG and optical pulse width was presented.Through the result,it shows that the performance of encoders/decoders is directly influenced by duty ratio. In view of the high cost of the ultrashort pulse,a new scheme was proposed with low cost and high duty ratio.
