[OT] -- Oh Joy! I'm Connected again!

I'd go with a 3/4" or 1" conduit between the buildings for the cable or fiber, and tie the ground bonds together between detached garage and house with an external link.

They do make inexpensive media converters, so you can run cheap pre-terminated fiber between garage and house, and turn it back into CAT-5 when you get there. (They make 100' "patch cords".) If the buildings have totally separate power sources you really should do it this way, so you don't chance ground loops.

And run the garage media converter from the garage power that is also running the garage computer - taking a power lead from the house just defeated the whole idea of ground-loop isolation...

Water in the conduit isn't that big a deal, most "Riser" rated cable sheath will resist some damp. And it's cheap enough you can replace it if it goes bad in 5 years. If you really want to only do it once they do make filled CAT-5 cable, with a conduit you don't need the full direct burial armored cable.

Ah, you young pups. Have no clue what communication is. When I was a kid, we had paper cups and a string to run from the house to the garage.

You must be too young fto remember speaking tubes. There were no paper cups back then.

Paper cups are just a modern cost reduction ruse, with a severe lifetime penalty. We used a clay pot and cat gut.

My buddy next door and I had tin cans full of rocks at each end that we used to "ring" our string telephone by tugging on the string. We thought that was quite advanced! The best talking cups were the round Quaker Oats boxes.

Actually, I do fto remember speaking tubes. You'd blow into it, and it would whistle at the other end. Until the other person pushed the little handle.

Oohhh... a greenie? Back to the Earth? Wore leather shoes, and denim jeans, too?
