Optical fiber is an important medium, which can realize low loss of light propagation, which is of great significance for restoring input information and realizing low loss transmission of information. Because the development of optical fiber communication technology in China is in its infancy, there are still some shortcomings in its development. The existence of these problems has greatly hindered the development of optical fiber communication technology. Based on the understanding of the current development situation of optical fiber communication technology in China, the author will discuss the development, application and future development trend of optical fiber communication technology in order to provide practical and feasible reference suggestions for relevant scholars and staff in the research of optical fiber communication technology.
Optical fiber communication and its related concepts
Optical fiber consists of core layer, outer layer and cladding, in which the refractive index of core layer is greater than that of cladding, and silicide is generally used. When light enters the optical fiber, because the refractive index of the core medium is greater than that of the outer layer, when the incident angle meets certain conditions, total reflection will occur, and the incident light will not be refracted at this time, so that the transmission of optical energy can be close to 100%. The main purpose of the outer layer is to improve the toughness of optical fiber and reduce the external damage to optical fiber. Optical fiber communication is a communication technology based on the above characteristics of optical fiber. It mainly uses light waves as carriers to load information onto light waves, and then realizes the effective transmission of information through low-loss transmission of light waves in optical fiber. It can be said that the development history of optical fiber communication is very rich. Since 1966, scholars have studied silica optical fiber, which has played an important role in promoting the development of optical fiber communication and opened a precedent for the research and development of optical fiber communication technology.
Subsequently, with the continuous development of optical wave amplification technology, optical fiber amplifier came into being, which is of great significance to realize optical amplification of optical fiber optical wave signals and improve the transmission efficiency of optical wave information. At present, optical fiber communication technology mainly includes five aspects: signal is output, signal light wave coupling, optical signal transmission and amplification, light wave signal dissociation and signal input. The main features of optical fiber communication technology are as follows. First of all, we know that perfect monochromatic light waves do not exist, and all light waves contain a little bandwidth.
When the bandwidth value is less than the resolution limit of human eyes, what we see is the so-called monochromatic light waves. The wider the frequency band of light wave, the greater its information content. Compared with copper wire, optical fiber medium has a better transmission bandwidth, which can greatly enhance the information capacity, which is of great significance for the transmission of big data. Secondly, because the total reflection of light is realized, the loss of optical information transmission can be greatly reduced. Furthermore, Shi Ying materials are not active in chemistry, are not easy to be corroded, and have good insulation properties, which can greatly avoid the influence of lightning, water dew and radiation, which is of great significance for ensuring the life of optical fibers. In addition, the optical fiber is flexible and easy to lay, which reduces the process difficulty and cost, and is of great significance for realizing high-security transmission.
