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 …

I’m using Fathom-X for communication on a pipe rover. It’s works (more than 10 mbit/s, no precise tests done) over 750m on a cheap AWG24 shielded twisted pair(not working with the same cable over 800m). AWG22 shielded twisted pair should do the job for the communication part.
