you can rent a time domain reflectometer for this purpose… it sends out a signal and then listens for the echos back and calculates the distance. problem is they arent accurate the first like 500 feet so you have to add a reel of 500 ft of matching cable to the end first. electrorent.com rents them.
Comment on Just finished wiring the garage to the house - and find that the wire is damaged! Now what?

Higher end cable testers can show you where the break is, but it will be far more expensive that a new cable.

I had an AMD Phenom-II era motherboard that claimed it would be able to do that. OP, you might be able to find an old NIC/mobo that could do this for cheap.

My TP link switch can detect faults and cable length. I’m not sure it can do both together but it’s possible. Worth checking if you have a switch with those features

Hmm, interesting! I have a Synology switch, gotta read up on its capabilities.
