Abstract

Abstract:

In order to satisfy the increasing optical testing requirements in PON，OTDR integrated in optical module is constantly developing.For the PON architecture based on OTDR integrated in optical module，the data transmission function and data analysis function of its OTDR relative interfaces were proposed，the OTDR data file structure and the OTDR data content were analyzed，and the data format of OTDR was defined.Therefore，the universal integrated OTDR data format can be realized.

Key words: interface, OTDR, PON, data

项目	二进制存储	文本
文件大小	如果点数固定，文件大小相对固定，总体文件大小较小	文本方式存储空间大，传输带宽要求大，建议采用压缩的文本格式，减少传递的数据量。对接入网中大量端口的周期监控测试的影响要进一步评估
可视化	不能够直接解析和不可视	取决于人对协议格式的熟悉程度，可简单设置显示测试曲线
信息安全	较为安全	信息直接显示，安全性稍低
开发、调试	需要解析工具配合	便于网元网管独立调试，可以依据实例文件进行开发
互通	需要互通测试，出现问题时需借助解析工具来判断和分析定位问题	事例文档直接对比分析，迅速定位问题
升级、扩展	需要重新研发文件解析器，工作量较大	现有文本解析器简单调整
实现方面	传统方式，由于使用无符号int方式存储，数据点需要预处理	压缩消耗一点CPU资源；压缩解压技术采用GZIP开源、自由
