Digital isolation between Ethernet hub and streamer

@mitch2 If you are already running optical there's very little you can do to improve upon that.

Don't most good servers/streamers also provide some form of isolation?

@mitch2  - Galvanic isolation is required for Ethernet signals, but due to how capacitors may be used across the coils isolation could be improved on a bit.

Personally I'm more worried about surges from outside the home coming in and frying all my HT equipment which is cable connected to it so I like to put isolators which are rated to UL 60601 at the end of long cables, close to my HT switch to reduce those chances.  I don't know of any boutique/audio isolators however which have this rating.
