摘要

基于所构建的PON OTDR系统的ODN衰减事件检测的分析模型和相关试验结果，研究了反射器在PON的OTDR测试诊断系统中的作用及其必要性。结合运营商的实际需求，提出并比较了反射器的几种实现方案，探讨了反射器的技术指标要求，并介绍了反射器相关的国际标准化进展。

Abstract

A mathematic model was built-up to analyze ODN attenuation event detection in OTDR system of PON

and then combining the mathematic analysis and experimental result

the application value and necessity of wavelength-selective reflector in PON optical link test and diagnosis system were investigated. Based on operators' requirements

several implementations of reflector were proposed and analyzed

and technical requirements for reflector were given. Finally

the international and domestic standardization progress of reflector was introduced.
