We are currently working on a custom project, and are considering using the Fathom-X as an alternative to fibre optics. Does anyone have any experience using these boards on longer tethers? For our project, we need a custom tether 800 meters long, with both 400 VDC supply and communication (twisted pair if we go for the Fathom-X). I realize that the electrical characteristics of the tether itself will play a large role, but the information on the board mentioned a theoretical 2000 meter max tether length, so it would be interesting to hear if anyone has tried using them with longer tethers, and what their experiences were.
Looking forward to hearing from you guys!
