Fiber-optic communication has become the mainstream, so why it will replace the traditional communication medium to become the next generation of mainstream communication media, the following Fiber Optic Splice Closure manufacturers will introduce the advantages of fiber-optic communication. First, the optical fiber communication capacity is huge, and communication confidentiality is good. In general, the security of wireless telecommunications depends on the password. Second, cable telecommunications leaks a lot, so it is difficult to eavesdrop. Light travels through the fiber and does not leak out, making it extremely difficult to eavesdrop. Third, telecommunications and automation systems that use electronic technology have a problem that prevents mutual interference. Optical fiber communication transmits light, which is immune to any electrical interference; the light in the optical fiber does not leak and thus does not interfere with each other. Fourth, fiber-optic communication does not require non-ferrous metals as conductors, which can save a lot of non-ferrous metals, and at the same time save construction costs and facilitate construction. The fiber consumption of the fiber is very small. The material can produce hundreds of kilometers or more of fiber, using oxygen, silicon, and other abundant and easy raw materials. Many fiber optic cables are not only the thickness of the pen but only a few meters per kilometer. From kilograms to tens of kilograms, it is soft and flexible, easy to transport and lay.
