Optical Cable for Midi

Hi all,

We are trying to send Midi over approx. 100m distance from one laptop to another (From Ableton into TouchDesigner). We’ve used rtpMIDI to send midi over ethernet before, but over long distances this doesn’t work, especially with electrical interference in venues.

In theory, if we send out via ethernet port, convert to optical with a converter and transceiver, and then convert back again on the other side, this should create a network similar to the ethernet option that would be able to carry rtpMIDI. In theory that is. Can’t seem to find anyone using this solution online for long distance MIDI, which is slightly worrying as it seems so logical.

Has anyone had any experience using optical and know if this would work or not?
