Affordable LAN Isolator

Sorry for my bad, I finally found that the isolating transformers are actually integrated inside RJ-45 connector. This is commonly found in router switches, PC and also streamers where LAN connection is used.

I was looking for SMT isolating transformers on the board prior to the transceiver chip, but so far I didn’t found one. It looks something like this…

So essentially LAN connection is indeed galvanic isolated from the transmitter and the receiver.

Thank you @AMP
