英文摘要：

In order to improve the surface quality and machining efficiency for the end-face of fiber optic connector and to advance the performance of transferring optical signals, the conventional polishing way must be improved to meet the requirements of next generation fiber optic connector with lower insertion losses and return losses. This paper discussed a new ultrasonic polishing in which the ultrasonic energy was introduced to the interface of common polishing, and compared this new polishing process with the common polishing process in the material removal rate （MRR） and polishing quality. It has been proved that the MRR and machining quality are improved greatly; the insertion loss and return loss below 0. ldB and -60dB are obtained respectively. This paper also applied a simple analysis on the mechanism of the new coalescence process. The conclusions are useful to further researches and industrial applications.
