一、光导纤维材料由多根光导纤维组成的光学电缆是目前信息容量最大,保密性最强的通讯导体。最初,光导纤维的基本原料是经过特别处理的柔性石英纤维。为保证降低石英的软熔温度,便于加工,提高纤维的透明度,减少光传输过程中的损失,增大纤维单位横断面最大的输出功率,在光纤维制造过程中需要加入Sb_2O_3等澄清剂和光纤芯部及表层的折射率调整剂,或以气相涂层等不同方法向石英
I. Optical Fiber Materials Optical cables composed of multiple optical fibers are currently the largest and most confidential communications conductors. Initially, the basic raw material for optical fiber was specially treated flexible quartz fiber. In order to reduce the reflow temperature of quartz, to facilitate the processing, to improve the transparency of the fiber, to reduce the loss during the light transmission and to increase the maximum output power of the cross-section of the fiber unit, it is necessary to add the clarifier such as Sb_2O_3 and the optical fiber The core and the surface of the refractive index adjustment agent, or the vapor phase coating to different methods such as quartz
