日本日立制作所日立研究所开发出高耐热塑料光导纤维。这种塑料光导纤维由热固性树脂通过在交联聚合过程中成纤的工艺,配以耐热性有机氟树脂皮层和耐热套管而制成。该产品如采用一股的发光二级管和光电二极管,传光距离为20米左右,可在汽车上使用。如采用半导体激光强光源,可在100 Hitachi Institute Hitachi Institute to develop high heat-resistant plastic optical fiber. The plastic optical fiber is made of a thermosetting resin by a process of fiber-forming during cross-linking polymerization, together with a heat-resistant organic fluororesin sheath and a heat-resistant sleeve. The product, such as the use of a light-emitting diodes and photodiodes, light transmission distance of about 20 meters, can be used in the car. Such as the use of semiconductor laser light source, available at 100
