Need for audiophile switch if using ethernet optical??

But optical eliminates noise. So why worry about a noisy switch that precedes optical ethernet?

So does having an optical ethernet connection between a switch and a network player eliminate a need for an audiophile grade switch?   
What value is there in having a really great switch due to having an optical connection ? 

I think optical is game changing and may cut down on lots of electronics in a player.  Dare say make players better and cheaper.

my lumin player has an optical port.  No need for opticalrendu thingy.
