无源光网络系统测距技术及其实现

The PON's ranging technology and implementation

介绍了无源光网络测距技术的工作原理 ,描述了测距过程的主要步骤以及完成测距所需要解决的关键技术问题 ,最后阐述了作者设计的完成测距功能的主要模块 ,该模块已成功地应用到作者所在研究所研制的 ATM- PON系统中。现场试验表明 ,系统的测距精度及范围等指标完全达到设计要求。

This paper introduces the theory of ranging technology of passive optical network, the main steps of a ranging process and the key technical problems of ranging. Finally, the thesis introduces the major modules of ranging function, which is implemented in our ATM PON system successfully. The result of system test proves that the features such as ranging precision and scope of system meet the design requirements completely.
