Is internet cable in house a hot mic?

I doubt it. Sounds like this needs some pretty special equipment at the end of the fiber. Also not clear that it can be used concurrently with data transmission over the fiber. Could be that the company is lighting up unused fiber? Cheap way to get audio surveillance along a vast stretch of pipeline that happens to have some dark fiber sitting beside it.
