玻璃光纖是由高折射率的光學(xué)玻璃芯料與低折射率的光學(xué)玻璃皮料所構(gòu)成。當(dāng)光線以一定角度進(jìn)入光纖后，在芯與皮界面上發(fā)生多次全反射，將光能由一端傳至另一端，實(shí)現(xiàn)光的傳導(dǎo)。多組分玻璃光纖主要性能參數(shù)：?jiǎn)谓z直徑20~55um；數(shù)值孔徑0.5~0.75；透過率每米>55%;光譜范圍380~1350nm。
Optical fiber is new functional materials developed in the last century. With the rapid development in recent years and the enhancement of technology in various industrial fields, optical fiber products have increased wider range of applications. Non-communication optical fiber is not used for fiber-optic communications but the various optical fibers, including glass fiber, silica fiber, plastic optical fiber, liquid-core optical fiber.
