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?
