The fiber is a very thin, low-consumption light guide fiber made of high-conductivity dielectric material, consisting of a core and a cladding. This is the meaning of fiber, so what is the specific fiber operating principle? DOME Fiber Closure manufacturers will share the working principle of fiber and common fiber materials. Light is transmitted through the fiber, utilizing the total reflection of light. The incident angle of incident light and the reflected angle of reflected light follow the law of refraction. When the incident angle increases, the angle of reflection also increases. When the incident angle increases to 90°, the incident ray is returned to the original medium. This phenomenon is light. Total reflection. Therefore, when the angle between the light incident on the optical fiber core and the optical axis is less than a certain value, the light is reflected at the interface. At this point, the light bends along the zigzag path in the fiber core, but the cladding is not removed. Fiber optics can bind and transmit light from the infrared to the visible region, as well as sensing power. The optical fiber can transmit the light and the light, the change of the light point, and the like from one end to the other end. There are three types of fiber materials: 1. High purity quartz glass fiber. This data consumption is low, at the wavelength, the lowest is 0.447db/km. The silicon-based data is used as the core, and the borosilicate data is used as the cladding multimode fiber, which consumes a minimum of 0.5 DB/km and a similar consumption-spectral curve. Adopting the ternary compound data, it is possible to obtain the best consumption-spectral curve. 2. Multi-component glass fiber. It is usually made of more conventional glass and consumes very low. For example, the Sodium-borosilicate glass fiber has a minimum consumption of 3.4 DB/km at λ = 0.84 μm. 3. Plastic optical fiber. Compared with quartz fiber, it has the characteristics of lightweight, low cost, good flexibility, and convenient processing, but it is consumed at r=0.63 micron to 100-200db/km.
