Silica Fiber is the optical fiber that uses silica (SiO2) as the main raw material and according to different doping amounts to control the refractive index distribution of the fiber and the layer. The quartz (glass) series optical fiber has the characteristics of low consumption and broadband. It is now widely used in cable TV and communication systems.

The advantage of quartz glass light -guided fiber is that the loss is low. When the light wavelength is 1.0 to 1.7 μm (about 1.4 μm), the loss is only 1DB/km, the lowest at 1.55 μm, only 0.2dB/km.

Fluoride fiber

Fluorine Doped Fiber is one of the typical products of quartz fiber. Generally, as a 1.3PM wave field, in the universal fiber, the doped doping control of the core of the fiber is percuted (GEO2), and the packaging layer is made of SIO. However, most of the core of fluoride fiber uses SiO2, but in the bag layer, it is mixed with fluorine. Due to the phenomenon of light scattering caused by changes in refractive indexes. Therefore, it is better to form a doped factors that want to form a refractive index change factor. The role of fluorine is mainly to reduce the refractive index of SIO2. Therefore, it is often used for doping of the layer layer. Due to fluoridomial fiber, the core does not contain fluoride doped that affects the refractive index. Because its Ray disappears is small, and the loss is close to the lowest value of theory. So it is mostly used for long -distance light signal transmission.

Compared with the optical fiber of other raw materials, quartz fiber also has transmittance from ultraviolet light to near -infrared light. In addition to communication purposes, it can also be used in fields such as light guide and conductive images.
