About 20 years ago I put an aerial fiber and a 50 pair between buildings, for temporary until they got the fiber equipment, I used the last 4 pairs of the cat3 for network connection. They used that for ten years until the owner sold the IT company. I think they were doing mostly computer repairs over there and email for technicians that were on the road.
