To understand how a fiber optic cable works, you can imagine a plastic straw or flexible plastic pipes. Then, imagine the pipe has a length of one hundred feet and you look inside of one side of the pipe. A fiber optic cable is made of pure glass fibers. It means even if the cable has a length of up to hundreds of meter, light can still be transmitted from one end to the other. The glass fiber strands designed very subtle as well. Its thickness is approximately equal to the thickness of human hair. Strands of glass fiber coated by two layers of plastic. It will get the equivalent of a glass fiber around the mirror. This mirror produces a total internal reflection just as if we were in a dark room with a glass window, then you are directing the flashlight 90 degrees perpendicular to the glass. The light will be translucent flashlight out of the room. However, if the flashlight is directed with a low angle, then the glass will serve as a mirror that will reflect light flashlight into the room. It makes the optical fiber’s light goes through glass fiber at a low angle.
Perhaps some of you still have problem in understanding about how such fiber optic works. Yet, what you can simply understand is that fiber optic technology may indeed provide you with quality and better communication technology indeed. Just conduct review first if you want to gain better understanding about such fiber optic technology.
