I suspect they are data, voice, or video jacks. Found in a conference room for a building from the 80s-90s. It’s the same wall as the TV. There’s also other existing RJ45 Cat 5 ports.

    I think they are optical cable connectors for lan. But I might be really wrong on this one.

      I don’t think optical fiber cables do patch through. They’re basically just point to point. This port also doesn’t seem to do anything optic-wise. Or even copper for that matter. The ports don’t seem to have anything behind them.

      Edit: wait I think I see two holes that could be for that
