摘　　要：光纤强度是表征光纤物理机械性能的重要参数,它直接影响到光纤通信及传输系统的可靠性。影响光纤强度的因素大多来自光纤生产过程,采用抗张强度试验方法,通过开展合格保偏光纤与涂覆层不均匀、应力区变形、纤芯偏差及应力区存在夹杂物等不合格保偏光纤的拉断力与位移对比试验,分析了影响保偏光纤强度的主要因素和形成原因,为研制高强度光纤奠定基础。The optical fiber strength is an important parameter of characterizing physical and mechanical fiber properties. Itdirectly affects the reliability of the optical fiber communication and transmission system. Factors affecting the fiber strengthmostly come from optical fiber production process. This paper uses tensile strength test method to carry out tensile force anddisplacement experiment for qualified polarization-maintaining fiber and unqualified polarization-maintaining fiber withcoating layer asymmetry,stress area deformation,fiber core deflection and stress area inclusions and then make compari-son of the experiment results. Main factors influencing the intensity of polarization-maintaining fiber and the forming reasonwere analyzed,aiming to lay a foundation for the development of high strength fibers.
