0引言在光缆的实际生产中,经常面临光缆产品拉伸性能欠佳,但又无法准确判断导致该问题的具体原因是出现在设计环节还是生产环节,这使得众多设计人员及工艺人员深受其累。光缆拉伸试验通常是测试指定力值下的光纤应变及相应的附加衰减,以检验光缆的拉伸性能是否能满足客户或相关标准的要求[1]。通常光缆拉伸试验的判据为光缆拉伸试验曲线,即光缆拉伸—应变曲线。 0 Introduction In the actual production of optical fiber cable, often faced with poor tensile properties of optical cable products, but can not accurately determine the specific cause of the problem is in the design or production link, which makes many designers and process staff by its tired. Optical fiber cable tensile test is usually to test the fiber strain under the specified force value and the corresponding additional attenuation to test whether the tensile properties of optical fiber cable can meet the requirements of customers or related standards [1]. Usually the criteria for optical cable tensile test optical cable tensile test curve, that is, cable tensile - strain curve.
