If you want to understand how a fiber optic cable works, except to consult with the fiber optic cable supplier,I now,recommend you that you should have a clear impression in your mind of the essence of a fiber optic cable.
Based on the assumption, let’s start to imagine a pipe that is several miles long. Now imagines that the inside surface of the pipe has been coated with a perfect mirror. Now imagines that you are looking into one end of the pipe. Several miles away at the other end, a friend turns on a flashlight and shines it into the pipe. Because the interior of the pipe is a perfect mirror, the flashlight’s light will reflect off the sides of the pipe (even though the pipe may curve and twist) and you will see it at the other end. If your friend were to turn the flashlight on and off in a morse code fashion, your friend could communicate with you through the pipe.That’s the nature of the production of the fiber optic manufacture in China.
After you take a note of the essence of the fiber optic cable.But when making a cable out of a mirrored tube would work, but it would be bulky and it would also be hard to coat the interior of the tube with a flawless mirror. A actual fiber optic cable is therefore made out of glass. The glass is incredibly pure so that, regardless of the fact that it is several miles long, light can still make it through (imagine glass so transparent that a window several miles thick still looks clear). The glass is brought into a very thin strand, with a thickness comparable to that of a human hair. The glass strand is then coated in two layers of plastic.High quality fiber optic equipmentand other kinds of products are all same in this aspect.
