I saw a machine a while back that could locate fibre optics but the more I think about it was'nt a cat as such. I think it was a ground penetrating radar?

Could be or they may have a conductor in them to power up repeaters, I don't know.

 

One of my daughters' boyfriends father was researching ground penetration radar for the MOD a long while back, more recently a late friend was getting involved with research at West London University where they were turning from mapping root systems to   detect cavities in wood on old oak (timbers on Victory IIRC) the claim was it could detect annual rings as well.

Although there is a radio detection cat that claims to be able to locate communication cables. I wonder if they are referring to Ethernet?

As I said if any electromagnetic radiation leaks out then the CAT can pick it up. Ours were optimised for mains frequency, radio frequency and the generator frequency, I suppose the more different frequencies you could tune it to the more chance of locating something.

 

The problems that arise with some electrical supplies is if they both live and neutral are switched off at the supply side and the earth is well shorted to ground so any induced currents are dissipated. Then there is no noise to detect.
