The material removal mechanism in optical fiber lapping is presented. With diamond lapping-film whose abrasive grain size is from micron to sub-micron, when the nominal lapping pressure was 0.48 MPa, the optical fiber end-face lapping experiment was conducted on optical fiber connector lapping machine of KE-OFP-12. The experiment results show that there are three material removal modes during lapping optical fiber,i.e. brittle fracture mode, semi-brittle and semi-ductile mode, and ductile mode.

The material removal mechanism in optical fiber lapping is presented. With diamond lapping-film whose abrasive grain size is from micron to sub-micron, when the nominal lapping pressure was 0.48 MPa, the optical fiber end-face lapping experiment was conducted on optical fiber connector lapping machine of KE-OFP-12. The experiment results show that there are three material removal modes during lapping optical fiber,i.e. brittle fracture mode, semi-brittle and semi-ductile mode, and ductile mode. These modes are mainly controlled by abrasive grain size; there appears brittle-ductile transition's critical point when the lapping-films whose abrasive grain size is 3 μm is used to lap optical fiber. And these material modes are analyzed theoretically. The surface roughness can reach nanometer grade and there are not any scratches and cracks on the fiber end-face when fiber material is removed by ductile mode; and only sub-micron grade surface roughness can be gotten when fiber material is removed by brittle fracture mode. It proves that the ductile lapping mode is an effective method that improves surface quality of fiber end-face.

给出了研磨光纤时的材料去除机理,选用粒度为微米及亚微米级的金刚石磨料砂纸,在研磨压力为0.48Mpa时,在KE OFP 12型光纤连接器研磨机上对光纤端面进行了研磨实验。结果表明:光纤研磨加工的材料去除存在脆性断裂、半脆性半延性、延性等3种模式。材料去除模式主要取决于磨料的平均粒度,磨料粒度为3μm时,为脆性断裂到延性研磨的临界转换点。并从理论上对结果进行了分析,光纤以延性模式研磨加工时,光纤表面粗糙度Ra可达到纳米级,其表面看不到任何划痕,而光纤以脆性断裂模式研磨加工时,其表面粗糙度只能达到亚微米级,证明材料以延性模式去除是提高光纤表面质量的有效方法。

The study on high quality surface formation mechanism in lapping of optical fiber end-face has become an important topic about improving performances of optical fiber connectors. With diamond abrasive lapping-films whose grain sizes are from 0.5μm to 6μm used, the optical fiber end-face lapping experiments are processed on optical fiber connector lapping machine, whose style is KE-OFP-12. The experimental results show that there are three material removal modes during lapping optical fiber, namely, brittle fracture mode, semi-brittle & semi-ductile mode, and ductile mode. These modes are mainly controlled by abrasive grain size. Brittle-ductile transition's critical point appears when the lapping-films whose abrasive grain size is 3μm are used to lap optical fiber; and they are analyzed theoretically. The surface roughness from ductile lapping mode is much less than that from brittle fracture lapping mode, and the ductile lapping mode is an effective method that improves surface quality of fiber end-faces. The surface roughness Ra 5 nm can be obtained and there are not any scratches and cracks on the fiber end-face when fiber material is removed by ductile mode; it makes insertion loss and return loss of optical fiber connectors meet the requirements of high-speed and broad-brand optical fiber communication.

研究光纤端面研磨时高质量表面的形成机理已成为提高光纤连接器质量和制造效率的重要课题。选用粒度为0.5-6.0μm金刚石磨料砂纸,在KE-OFP-12型光纤连接器研磨机上对光纤端面进行研磨,发现光纤研磨加工存在脆性断裂、半脆性半延性和延性等三种材料去除模式,且材料去除模式主要由磨料粒度控制,磨料粒度为3μm 时,为其脆延转换的临界点,并从理论上对其进行了分析。试验证明以延性去除得到的光纤表面粗糙度远低于以脆性断裂去除得到的表面粗糙度,是提高光纤研磨表面质量的有效途径。光纤以延性模式研磨加工时,光纤表面粗糙度可达到5nm,其表面看不到任何划痕,可使光纤连接器的插入损耗及回波损耗等光学性能满足高速、宽带光纤通信的要求。
