Optical fiber communication is the main transmission means of modern communication networks. Its development history is only about 20 years, and it has experienced three generations: short-wavelength multimode fiber, long-wavelength multimode fiber, and long-wavelength single-mode fiber. The use of optical fiber communication is a major change in the history of communications. More than 20 countries, including the United States, Japan, Britain, and France, have announced that they will no longer build cable communication lines and are committed to the development of fiber-optic communications. China's optical fiber communication has entered a practical stage. Let's take a look at the fiber-optic communication with the DOME Fiber Closure manufacturer. The birth and development of optical fiber communication is an important revolution in the history of telecommunications, and satellite communications and mobile communications are listed as technologies in the 1990s. After entering the 21st century, due to the rapid development of Internet services and the growth of audio, video, data, and multimedia applications, there is a more pressing need for high-capacity (ultra-high-speed and ultra-long-haul) optical wave transmission systems and networks. Compared with the previous electrical communication, the main difference between optical fiber communication is that it has many advantages: transmission frequency bandwidth, large communication capacity, low transmission loss, long relay distance, thin wire diameter, and lightweight, and the raw material is quartz, which saves metal materials. Conducive to the rational use of resources; strong insulation and anti-electromagnetic interference; also has the advantages of strong anti-corrosion ability, strong radiation resistance, good routable, no electric spark, small leakage, strong confidentiality, etc., can be used in a special environment or military Used on.
