摘要: 为测量光纤的机械强度,设计了光纤拉力测试机及专用夹具,并用其测试了常温和经硫化环境处理的光纤的机械强度,试验测得常温环境下,康宁900光纤的平均最大拉力为61.4N,SMF-28裸光纤的最大拉力为49.3N;经硫化环境处理后,两种光纤的平均最大拉力分别为57.3N和47.6N。用断裂模型分析法,采用扫描电子显微镜(SEM)对常温光纤和经硫化处理的光纤断面进行观察检测,比较两者断面的差异。用X射线光电子能谱仪(XPS)进行进一步检测,证明了经硫化处理的光纤中硫的存在,解释了经硫化环境处理的光纤机械强度减小的原因。

Abstract: n order to testing the mechanical strength of optical fiber, the fiber tensile tester and special fixture special fixture are designed. They are used to test the mechanical strength of common temperature fiber and vulcanized fiber. In common temperature, the average maximum tensile strength of Corning 900 fiber is 61.4N, and that of SMF-28 bare fiber is 49.3N. After vulcanization, the average maximum tensile strength of both kinds of fibers is 57.3N and 47.6N respectively. By the method of Fracture Model Analysis, the Scanning Electron Microscope (SEM) was used to observe and detect the common temperature fiber and the vulcanized fiber. And the difference of the sections between the two fibers had been compared. The X-ray Photoelectron Spectroscopy(XPS) was used to further detect. It was proved that sulfur exists in the vulcanized fiber. The reasons for the decline of mechanical strength of vulcanized fiber are explained.
