摘　　要：基于光地址码的自相关和互相关特性分析了光纤延迟线光编/解码器的工作原理和光纤延迟线长度选择的依据.在理论分析的基础上采用实际制作的光编码器搭建了两路的OCDMA实验平台,进行实验分析并得到相应的实验结果,表明利用并行光纤延迟线可以成功地实现OCD-MA编解码.The working principle of optical encoder/decoder on the base of optical orthogonal codes is analyzed.It gives the principle of choosing the length of optical delay line.Moreover,an OCDMA platform is constructed by using two optical encoder/decoder made practically,then be experimented and analyzed with the corresponding experimental results attached.The experiment validates that optical encoder/decoder can be accomplished by optical fiber delay.
