Ultra Low Profile Cable Duct

in Off-Topic
Hey all, I have some Toslink cables I need to run across a room that I need protected from foot traffic. I have an area rug to run them under, but need some ducting or another option to keep them from... cracking under the pressure.. (get it?)
Anyone have any suggestions on some very low profile protectors? I have no issues with the protector being visibly higher than the rest of the carpet, but I do not want it to be a trip hazard as it will not be visible.
