Has anyone used fiber-optic to ethernet media converters?

[Guest guest]

Hey all,

I've been considering using (if I can find it affordably) fiber optic cable

instead of ethernet. I know you need to use a " media " converter at either

end to turn the light pulses from the fiber optic into ordinary signals that

travel along a short piece of ethernet cable to the computer and modem.

Can anyone comment on how electrically dirty these media converters are when

they convert fiber optic signals into ethernet signals?

I know that they use switching AC-DC power supplies, though I've seen some

that are powered directly through the computer's USB port. Could this be a

clean enough solution, since the USB ports are putting out DC electricity

directly from the computer's mainboard?

I'd really appreciate your help. Thanks!
