为了提高光纤连接器的回波损耗,首先对加工变质层的形成机理进行了探讨,研究加工工艺参数对回波损耗的影响,研究结果表明磨粒粒径对回波损耗影响最大。同时对球面光纤连接器超精密加工技术进行了论述。 In order to improve the return loss of the optical fiber connector, the formation mechanism of the processing metamorphic layer is firstly discussed, and the influence of the processing parameters on the return loss is studied. The results show that the particle size of the abrasive has the greatest impact on the return loss. At the same time, the spherical optical fiber connector ultra-precision machining technology are discussed.
