What does the question mean? Do you mean why can't we use optical fibre instead of satellites or to provide an up-link or down-link to a satellite?
A geo-stationary satellite is 36000 KM above the earth's surface. That's a lot of fibre and it would break under its own weight. If you had that much fibre, you don't need a satellite, you could just connect 2 places on earth by fibre optic cable.
Satellites in low earth orbit have to circle the earth to stay in orbit, so joining cable to them is not an option unless you want the earth wrapped up like a ball of string.

Because you can't run the fibers from Earth to space.

Yes but it would take an awfully long cable.
