Application and development trend of optical fiber communication technology

　　Today, with the rapid development of Internet technology and the increasing demand for communication, the service requirements for the communication industry are getting higher and higher. Among them, optical fiber communication technology has experienced more than 30 years of research and application in China. The birth and development of this communication technology belongs to a revolutionary development of the telecommunications industry. This communication technology can optimize the quality of information transmission and reduce the possible crosstalk problems, and can achieve very ideal practical results. At present, the application scope of optical fiber communication technology is more and more extensive, from telecommunication industry to TV transmission, field monitoring in military and industrial production, electric power, traffic monitoring and cable TV network. This paper mainly discusses the practical application and future development trend of optical fiber communication technology, and puts forward the author’s thoughts and suggestions for reference only.from optical cable From the reference value, it can also bring a lot of inspiration to other industries. https://www.fibercan-network.com/

　　The application of optical fiber communication technology mainly includes: using light wave as information carrier to realize communication function; Use optical fiber as a continuous propagation medium. At present, in terms of information communication, optical fiber communication belongs to the fourth generation communication mode. Its main characteristics are: light weight, fast propagation speed, small loss and small size, and its transmission frequency band is very wide, which can effectively resist most electromagnetic interference. These advantages make optical fiber communication gradually become the mainstream of society. At present, optical fiber is installed in most communication fields in China, and related businesses are still expanding, which has been recognized by more and more production and service fields. Understanding and studying the specific application of this communication technology can promote the development of informatization in China.

　　1 optical fiber communication technology

　　The so-called optical fiber communication is the optical fiber communication, which effectively transmits signals through optical fiber to achieve the purpose of information transmission. We can regard this optical fiber communication as an optical communication method with optical fiber as the medium [1″ target=_blank>. Among them, the main components of optical fiber are: coating, fiber core and cladding, while the inner core is usually only a few tens of microns or even a few microns, and its diameter is smaller than that of hair; Cladding is the middle layer, and the optical signal can be totally reflected in the fiber core by using the difference of specific refractive index between the fiber core and cladding, that is, the optical signal can be transmitted; Among them, the coating is mainly to improve the toughness of optical fiber, so as to protect optical fiber from damage. There is not only one light in the optical fiber communication system, but a large number of optical fibers are gathered together to form an optical cable. The reason why this kind of optical cable composed of a large number of optical fibers can transmit huge information in a unit time is mainly because the optical frequency of this optical cable is very high and the optical fiber transmission frequency band is very wide, so its transmission capacity is relatively large. The advantages of this optical fiber communication technology include: relatively small volume, very light weight, very few metal materials, strong electromagnetic interference resistance and radiation resistance, very good confidentiality, anti-eavesdropping, wide frequency band, good anti-interference performance, low price, etc. At the same time, the source of light materials used is very rich, which can reduce the application of many non-ferrous metals, and the diameter is very small and not heavy.

　　2.1 Application in Communication

　　At present, in the field of communication, optical fiber communication technology plays a very important role by using optical fiber as the transmission medium. Especially in metropolitan communication, local communication and international communication industries, optical fiber communication technology has been widely used [2″ target=_blank>. At the same time, the optical fiber communication technology is constantly expanding and has become a very key technology in the communication field, which has effectively promoted the further development of the entire communication industry.
