<div dir="ltr">If all else fails, the Cat6 cable at 100MBps might work better than you think. No optical isolation needed as the ethernet has transformer isolation at both ends, although PoE bypasses this. If you are running pipes around the place, it wouldn't hurt (much) to include a run or two as a backup plan. Even if there is interference from the electric fence, it has a low duty cycle, so the ethernet gear should just retry automatically.<div><br></div><div>Trevor</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, Nov 19, 2019 at 6:22 PM Henri Shustak <<a href="mailto:henri.shustak@gmail.com">henri.shustak@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">Hello again,<br>

Also, if you have not started trenching. I have had really good luck with Ubiquity (Chinese) Wi-Fi bridges. They are really quite amazing and at about $250 for a pair including POE injectors it is amazing.<br>
<br>
In the past that kind of out door gear was in the thousands. They also offer longer distance Wi-Fi to ethernet layer 2 bridges.<br>

I was thinking of running optoisolators at either end of copper, however a generous member of this group has offered fibre to the extent that would satisfy this run.
