日本电报电话公司开始将开发成功的氟化聚酰亚胺实际用作通信用部件。光通信用部件除要求近红外线至可见光区域的高透光性外，还要求折射率可控制性、耐热性、耐湿性等特性，通常的聚酰亚胺大量用作软性印刷电路板、软片盒、电子器件绝缘膜和涂料，但光透射性差，不适合光通信?
Nippon Telegraph and Telephone Corporation began the successful development of fluorinated polyimide actually used as communications components. In addition to requiring high light transmittance in the near-infrared to visible light range, optical communication components also require controllability of refractivity, heat resistance, moisture resistance and the like, and conventional polyimides are widely used as flexible printed circuit boards, Cassette, electronic device insulation film and paint, but poor light transmission, not suitable for optical communications?
