Yeah my thoughts exactly. OTDR is what the optical networking industry uses (for much larger runs of fiber) to find kinks/breaks.

It could still be a novelty if it uses a slightly different method or even materials. Hence why the advice is to get this on the hands of IP experts.

I wasn't commenting on the novelty aspect, I was more wondering in which situations the author's device might be better. Also, the author noted they started with a time of flight sensor, which would have made it extremely similar to OTDR
