However, I have a question reference other "isolation devices".
Is it possible to achieve galvanic isolation in an ethernet switch to provide the AQ benefits you have reported?

Hi Hector - indeed ethernet Galvanic isolation can be achieved with fibre ethernet, available at suprisingly accessible prices these days.
* edit: correction as per MattF's post below Cu ethernet is Galvanically isolated anyway *
Problem is at some point it has to be turned back to electrical signals for the RJ45 input of the M device.
Arguably there could be a benefit if only the last short leg is electrical if the network and it devices could be shown to cumulatively add noise which could be isolated by a fibre link to a good quality switch serving only the M device(s).
Anyone want to try it?
If differences are real, maybe there is a case for M to design in fibre ethernet ports in future, galvanic isolation achieved and of course the conversion to electrical data is then fully in M's control within the product.
