光纤连接器是光纤通信系统不可缺少的重要元件之一。日本光纤连接器的发展已渡过了研制阶段,进入了商品生产的新阶段。目前的研究是围绕着降低价格,进一步提高光学性能等方面进行。降低价格,主要是降低光纤插针体的造价,选用陶瓷插针体代替金属插针体;提高光学性能,主要是将光纤端面的平面接触改为球面接触,从而使反射光大大减少。 Optical fiber connector is an indispensable component of optical fiber communication system. The development of Japan’s optical fiber connectors has passed the research stage and entered a new phase of commodity production. The current research focuses on reducing the price and further improving the optical performance. Reduce the price, mainly to reduce the cost of fiber pin body, the use of ceramic pin body instead of the metal pin body; improve optical performance, the main plane of the fiber end is changed to contact with the plane, so that reflected light greatly reduced.
