With the rapid popularization of the Internet and the rapid development of Broadband Integrated Services Digital Network (B-ISDN), people's demand for information has shown explosive growth, almost doubling every six months. Against this background, the construction of information highway has become a worldwide craze. As the core and pillar of the information superhighway, fiber-optic communication technology has become a top priority. Many countries and regions have spared no effort to spend huge sums of money to develop fiber optic communication technology and its industry, and the fiber optic communication business has been developed unprecedentedly. Optical communication is a kind of communication mode using light wave as transmission medium. Light wave and radio wave belong to the same electromagnetic wave, but the frequency of light wave is higher than the frequency of radio wave, and the wavelength is shorter than the wavelength of radio wave. Therefore, it has the advantages of wide transmission band, large communication capacity and strong resistance to electromagnetic interference.
In addition, because the production, dissemination, exchange and application of information have a decisive impact on the national economy and national security, so, compared with other industries, fiber optic communication has more special significance. The fiber optic communication business is a huge systematic project. Its various components are interdependent, promote each other, *** with the forward development. Optical fiber communication technology itself, should include the following main parts: fiber optic cable technology, transmission technology, optical active devices, optical passive devices and optical network technology.
Light waves can be divided into infrared light, visible light and ultraviolet light according to their wavelengths. Infrared light and ultraviolet light is invisible light, they are the same as visible light can be used to transmit information. Optical communication can be divided into laser communication and non-laser communication according to the characteristics of the light source; according to the different transmission media, it can be divided into wired optical communication and wireless optical communication (also called atmospheric optical communication).
