Ultrasonic Mechanical Polishing of End Face of Fiber Optic Connector

为了提高光纤连接器端面的加工效率和加工质量,改善连接器光传输性能,探讨了在机械研磨的界面上引入超声能的复合研磨方式,设计了相应的超声机械研磨装置．实验结果显示,超声机械研磨效率是机械研磨的4- 8倍,光纤表面粗糙度达到2-5nm,插入损耗小于0．1 dB、回波损耗小于-60 dB．研究表明,超声机械研磨技术可以提高光纤连接器的研磨效率和质量,使传输性能获得显著改善．

To improve the surface quality and machining efficiency of the end face of fiber optic connector and to advance the performance of transferring optical signal of connector. A new way of polishing is discussed, in which the ultrasonic energy is applied to the interface of mechanical polishing and correlative equipment and experimental equipment are designed. The experimental results show that the material removal rate （MRR） of ultrasonic mechanical polishing is 4 to 8 times that of conventional polishing, and the roughness value is reduced from 20 nm to 2-5 nm for fiber end face. Especially, the insertion loss and return loss of optic fther are below 0. 1 dB and - 60 dB respectively. Also it is proved that the surface quality, machining efficiency and the performance of transferring optical signal of fiber optic connector are improved remarkably by ultrasonic/mechanical combining polishing.
