Etalon ethernet isolator.

[K4680]

To clarify, what I meant to say was that prefer the idea of the Etalon in comparison to 'optical bridge' type devices, that is Ethernet to Toslink to Ethernet converters, which do need external power.  Of course the Intona is a USB isolation type device, a different thing altogether.  Brain fade on my part in my earlier post.

I wonder if this is good? Is is certainly practical in use.. link to specs here: http://www.emosystems.de/wp-content/uplo...EN-85e.pdf

The schematic for the  Emosafe looks identical to the one posted yesterday by K4680, in terms of the 'LAN transformer' arrangement at least.

Also note that Antoine mentions the EMO Systems EN70 HD back in post #11. 

So very similar in principle, as to how the quality of components / performance compare, I have no idea.

Hello Confused,
the LAN isolators are mast all in the construction and technical data largely identical. It is important that the transmission is shielded and the performance category
ISO 11801 PermanentLink (PL), Class C, or better Class D. If you are running a GB-network, you should use Class D!
There are still isolators, which have protective diodes built in against excessive voltages!
