Ethernet between two buildings

I have to connect two buidlings on our campus that are relatively close together and wanted to ask if the setup I have for it sounds correct. we are using shielded cat5e for the task as both buildings have heavy machinery running. The length has to go from the shopfloor wiring closet to a ethernet lightning supressor on the wall, about 75ft, the second length goes from the lightning supressor inside one buidling thru the hole and over to the lightning supressor in the other building about 50ft , the final length goes from the lightning supressor to the front office off the other building whihc is about 150ft. so we are looking at about 300ft. I know that it is only supposed to go 328ft, but I wondered if the fact that the signal has to go thru the 2 lightning supressors--which wont regenerate the signal --will affect that 328ft limit. Could I just put a hub somewhere in the middle to regenerate the signal? would there be any difference if I put a hub or a switch?

If you're set on using ethernet, then yeah a hub will work just as well as a switch here, and put somewhere in the middle should repeat the signal like you need.

That said, running copper ethernet between buildings is usually discouraged due to the potential for different ground currents, but maybe that's something the lightning supressors will get around, can't say for sure on that. Fiber is generally the best way to go between buildings like that.

IMHO, for the environment and the distance and all the suppression (i.e lightening arrestors), I would spend a few dollars more and use fiber! Well, maybe not a few dollars more, but it could sure save you from problems and headaches down the road!

I absolutely do concur with CrashDummy_MS that "Fiber is generally the best way to go between buildings like that."

Point to point wireless bridge would by my 2nd choice, but throughput would be slower.

I agree with both you guys. Here's some fiber transceivers:

100 base $56 ea, 2km range

gigabit, $156, 300m range

1000ft of fiber $254

I'm not sure if that is in your price range though.

The price of fiber isnt too far out of my range, but we already have a big roll of cat5e STP, so I was just trying to utilize what we have on hand to keep costs down. I can keep it in mind if we start having issues. Thanks for the help.
