Fibers Light
![]() |

optic fibers are replacing copper wires because of high speed of light . is electric current not that fast???
there must have been expereimetnts on sample lenght a wire and a fiber that prove the data transmission speed of one is n times faster the other? How fast is it? this is
in reference to the below question where public talk of many theories of current and prove that electric current speed is 75 percent of light which i felt is not that big a differnce for change in technolgy.i think it should be drastic difference for such a technological revolution adn replacement of the older system.I WOULD LIKE TO KNOW REAL DATA OF SPEED OF CURRENT

It's not the speed, it's the bandwidth. The propagation speed of signals in copper wire and in glass fiber is comparable (typically 0.7c), but the glass has a potential bandwidth thousands of times wider than you can get with paired copper conductors. Copper twisted pair is good for a few megahertz bandwidth; coaxial cable can go up to a gigahertz or so, but fiber can do ten gigahertz easily, and more with advanced gadgetry.
