Is optical mostly a waste of time versus Ethernet?

The only value I see with a fiber optical cable is if you have a long long run.

All the noise coming into an optical fiber is preserved and comes out the other side. I guess there is a value in not creating more noise while it is traveling through the optical cable. But if it's a short run of two Feet then is it really worth it.  Seems a well shielded Ethernet cable would do just as fine without all the hassle of converting to optical which is a pain in the ass.

I always thought there was value with optical but it seems they're really may not be. Maybe I'm wrong.  It seems a switch likely produces a lot of noise and inserting an audio grade switch is very prudent and going optical really doesn't solve switch noise problem.  The benefit of re-clocking offered by a decent switch to clean up the signal is worthwhile.
