Etalon ethernet isolator.

[Confused]

Thanks for that K4680. So if I am interpreting this correctly, this is not passive filtering per Antoine's concerns. (Note that Antoine did not say it was passive filtering, he was simply concerned it might be) It simply allows the data through unhindered, whilst offering complete isolation from spurious electrical noise and grounding. Please correct me someone if I have got this wrong!

So if I have got this right, it cirtainly cannot do anything negative, and if electrical noise or grounding are an issue in a system, the issue is eliminated.
