Ethernet isolator

Which ethernet isolators work (or don’t work) in front of the BridgeII?

I tried a pair of tp-link gigabit multimode media converters, and couldn’t get the signal to the DSD.

Above is mentioned the Baaske MED MI 1005 .

Steve Nugent likes the > > EMO EN-70e isolator. Anybody know if that works in front of the BridgeII?

Other suggestions?
