Fiber optic is transmission data transfer which made from glasses or plastic. It’s shape very small and this tool can transfer light signal. The technology development very good, can bring out side this technology. The speed of transfer use fiber optic very fast, because it is made from plastic or glasses, so that the light signal if want spring back, will be back again, so there is no lose signal. The light from fiber optic will not go outside because drift index from glasses is bigger than drift index from air. So, fiber optic technology is very good for use as street communicate.
In principle, fiber optic spring back and extend in there. The light in the fiber optic will bring the data from one place to another place. And this technology has been there from for years ago, people have known about this technology. But this technology is not use. For the first generation, the system of fiber optic still simple and can be base for the next generation. The second generation, this fiber optic have capacity of speed ten times bigger than the first generation. For the next generation, it happened complete for that capacity of transmission and fiber optic always get some development.
