Advantages of Fiber Optics
Why are fiber optic systems revolutionizing telecommunications? 


Compared to conventional metal wire (copper wire), optical fibers are :

Because of these advantages, you see fiber optics in many industries, most notably telecommunications and computer networks. For example, if you have ever telephoned Europe from the United States or vice versa and the signal has been bounced off a communications satellite, you often hear an echo on the line. However, with transatlantic fiber optic cables, you have a direct connection with no echoes.
