How Does Data Travel Through Fiber Optics. Wait until you hear what happens inside the cable itself. In the real world we use copper cable or fibre optic (glass) to conduct electricity or light.

The core is a single continuous strand of glass or plastic that's measured (in microns) by the size of its outer diameter. Copper slows electrical current to about 70 % of the speed of light and glass slows light by about the same. Do this a million times, you find that the photon traveled 4.24 meters instead of 3 meters!

What is Fiber Optic?

So, the optical fiber transmits “data” by light to a receiving end, where the light signal is decoded as data. Copper slows electrical current to about 70 % of the speed of light and glass slows light by about the same. When a light ray goes from a denser transmission medium to a rarer one or vice versa, then its direction changes at the interface of the two medium. A laser at one end of the pipe switches on and off to send each bit.
