Don't get confused that 328 feet is just a powering issue. There are completely unrelated Ethernet and POE issues. 328 feet is magic for Ethernet, not necessarily for POE, although they tend to go together.
If you are feeding a micropop over 800 feet of buried Cat5 with no AC power at the far end, you have your hands full. I would buy some VDSL bridges (and spares), they aren't all that expensive, and after all you are feeding a micropop. Next time, I would bury at least 6 strand fiber and at least 12AWG for power (120VAC or 48VDC). And I would put it in conduit with a pull tape. You don't want to spend all the time and money burying 800 feet and then find out you buried the wrong thing. -----Original Message----- From: Af [mailto:[email protected]] On Behalf Of Adam Moffett Sent: Sunday, February 5, 2017 4:05 PM To: [email protected] Subject: Re: [AFMUG] PoE Cat5/6 cable distances You could just run 3x 12ga and run the 110 AC all the way out there. For a load as small as you're saying, you wouldn't even notice the voltage drop. ------ Original Message ------ From: "Chuck McCown" <[email protected]> To: [email protected] Sent: 2/5/2017 3:52:24 PM Subject: Re: [AFMUG] PoE Cat5/6 cable distances >I have run up to 600 volts on CAT 5. > >-----Original Message----- From: Dev >Sent: Saturday, February 04, 2017 10:00 PM >To: [email protected] >Subject: Re: [AFMUG] PoE Cat5/6 cable distances > >> > Are you trying to exceed 100 meters?
