Description
技术领域
本发明属于光纤制备技术领域,涉及一种光纤制备方法。
背景技术
光纤是一种由玻璃或塑料制成的纤维,可作为光传导工具。光纤裸纤一般分为三层:中心高折射率玻璃芯,中间为低折射率硅玻璃包层,最外是加强用的树脂涂层。光线在纤芯传送,当光纤射到纤芯和外层界面的角度大于产生全反射的临界角时,光线透不过界面,会全部反射回来,继续在纤芯内向前传送,而包层主要起到保护的作用。
光纤的种类很多,根据用途不同,所需要的功能和性能也有所差异。但对于有线电视和通信用的光纤,其设计和制造的原则基本相同,具体体现在(1)损耗小;(2)有一定带宽且色散小;(3)接线容易;(4)易于成统;(5)可靠性高;(6)制造比较简单;(7)价廉等几个方面。但现有的光纤由于光纤弯曲、挤压、光纤对接不良均会造成光纤的衰减,尤其是光纤制备过程中其光纤内杂质也是导致光纤衰减的主要因素,影响了光纤的使用效果。
