一种GEPON长发光问题解决方案

One solution for solved the GEPON constant optical issue

主要研究在现场应用中遇到的一个重要问题:ONU异常长发光导致PON系统业务中断,这个常发光问题得不到良好解决,GEPON大批量使用就不可能。通过分析问题的产生根源,提出相应的定位方法和解决方案,为今后的GEPON大规模部署提供了保障。

As we know, GEPON is one of next generation broadband access methods, it has many technical advantages which is studied and introduced in many papers, but this paper will focus on one important field issue which the ONU constant optical will interfere the normal service, if it can＇t be solved, it will block the GEPON mass applicationo The paper will cover the issue cause, issue oriented method and one new solution.
