Optical fiber light guide principle and optical fiber material

2020-06-19 16:25:23 Read

Optical fiber is short for optical fiber. It is a light transmission tool that uses the principle of total reflection of light in fibers made of glass or plastic. Optical fiber actually refers to a core made of a transparent material and a cladding made of a material with a lower refractive index than the core around it, and the optical signal of the optical fiber entering the core is reflected through the cladding interface , So that the optical signal propagates through the media in the fiber core. Fiber has two main characteristics: loss and dispersion. Optical fiber communication has the advantages of transmission frequency bandwidth, large capacity, long transmission distance, high quality and good confidentiality. The excellent characteristics of optical fiber make it widely and widely used in many fields such as optical fiber communication, sensing, image transmission, light transmission lighting and energy signal transmission, especially in the field of information technology.
