As long as the fiber cable 100% non-metallic it is permitted. See 770.133(A).
You do have to look at the conduit fill and the bending radius at any conduit bodies.
 
I have a fiber line that needs to be ran and the only open conduit has 480 power ran through it is it ok to run the fiber in with it
I can't think of any technical reason not to. But it appears to be sometimes prohibited and sometimes allowed by 770.133. Read it carefully.
