介绍波分复用无源光网络 ( WDMPON)的结构相对传统的 PON结构的优越性 ,同时分析了两种最新 WDMPON结构中采用的两项技术 :光源共享和频谱分割的原理和技术细节 ,最后指出 WDMPON是宽带接入网的最佳选择 .文中关于 WDMPON优缺点的讨论 ,对电信运营者考虑接入网应采取何种结构 ,具有重要的参考价值 .
This paper introduces the advantages of WDMPON architecture over the traditional PON architecture. It also analyzes two techniques used in the two latest WDMPON structures: the principle and technical details of light source sharing and spectrum segmentation, and finally Pointing out that WDMPON is the best choice for broadband access network.The discussion on the advantages and disadvantages of WDMPON in this paper is of great value to telecom operators in considering the structure of the access network.
