2. Fiber      
2.1 Description  
                 
The fiber is made of quartz glass (silicon dioxide), which is generally divided into three layers: the core is a 9 micron high refractive index glass core, the second layer is a 125 micron low refractive index cladding, and the outer layer is a protective resin coating with a diameter of 245 micron.
