splicing".本工程是“光纤熔接的速度与质量测试”。The fusion splicing task of the optical fiber is one of the most important and highly skills to install the optical fiber cabling system.Since the fusion splicing is the most frequently performed work,if the speed of the connecting work is slow,it will greatly affect the overall work time,resulting an increase in the installation cost.In addition,its work quality greatly affects the overall quality of the optical fiber cabling system.光纤的熔接是光纤布线系统安装中最重要、技术含量最高的环节之一。由于熔接是最常进行的工作，如果连接工作的速度较慢，将会极大地影响整体工作时间，导致安装本钱的增加。此外，它的工作质量很大程度上影响着光纤布线系统的整体质量。This Test Project proposal consists of the followingdocumentation/files:此测试工程由以下文档/文件组成:MD.pdf（This document）（本文档）Description of project and tasks工程和任务说明This project is to install FOE for rack colocation
