最初,光纤连接器用插芯是将金属棒材(铁、不锈钢等)切削外形后再加工Φ0 .1 2 5 mm的内孔制作而成的。采用金属棒材加工光纤连接器用插芯,较难控制产品的精度(特别是内孔的光洁度) ,且无法达到市场需求的大批量生产,因此,研发人员开始开发其它能够进行大批量生产的光纤连接器用 Initially, the optical connector ferrule is a metal rod (iron, stainless steel, etc.) after cutting the shape and then processing Φ0. 125 mm hole made. It is difficult to control the accuracy of the product (especially the inner hole finish) by using the metal bar to process the ferrule for the optical fiber connector, and the mass production can not meet the requirement of the market. Therefore, the researchers started to develop other optical fibers capable of being mass-produced Connector used
