日本电气通信研究所研究成功了世界上损耗最低的可塑光纤,每米的光损耗在0.1dB 以下。可塑光纤与石英系列光纤相比,可塑光纤轻,柔软有弹性,加工和处理都容易,富于经济性。并且,即使把传送光的中心部分(心线部分)增大到2—3mm 也能任意折弯,另外,因容易增大接收光的角度(开口角),故简化了光纤相互间和光纤与光源之间的连接技术。由于这些优点,在胃摄象机,汽车灯光用监控器等方面已开始使用可塑纤维。但是,以前的光纤光损耗最优良也在0.3dB/m 以上,要用在通信方面,存在着较大的问题,而期待着光透过性能优越的可塑光纤。
The Japan Institute of Electrical Communication succeeded in researching the world’s least wear-out optical fiber with optical loss of less than 0.1 dB per meter. Plastic fiber compared with quartz fiber series, plastic fiber light, soft and flexible, processing and handling are easy, economical. In addition, even if the central portion (core portion) of the transmitted light is increased to 2-3 mm, it is possible to bend it arbitrarily. In addition, since the angle (aperture angle) of the received light is easily increased, the optical fibers and the optical fibers and Light between the connection technology. Due to these advantages, plastic fibers have been used in stomach cameras, car light monitors and the like. However, in the past, the optical fiber loss was the most excellent at 0.3 dB / m or more, and there was a big problem in communication. Therefore, the optical fiber is expected to have excellent optical transmission properties.
