On the plus side, the optical cable can't carry or radiate trash. On the 
negative side, it's very likely that local electronics for it will come 
with a switch-mode PSU, which are notorious noise generators, and the 
electronics itself may be noisy. I'm on a cable modem, and use WiFi 
rather than wired Ethernet (which can radiate R). That's plenty fast 
enough to stream hi-def video and do teleconferencing, which are our (me 
and XYL) most demanding uses. These uses can be additive if others in 
your family are doing these things simultaneously.

If you don't need additional speed, I'd apply my rule that if it ain't 
broke, don't fix it.
