What are u using? Sent from Marconi's and Graham Bell's fused thoughts!!!

My favorite has been bend insensitive fiber. It is small and can make the same turns the Ethernet and power can without risking a break. It is also really thin and makes for easier movement when securing the cable. In terms of the PacketFlux gear in the air, if the site is done properly and grounded, there shouldn't be any problems. I have only had to replace two of them since we started building our larger sites out like this. The list Gerard gave is missing two items I believe: breakers and fuses. More often than not, the fuses on the ground are the ones that go. We have one site where our box is 360ft on the tower. This site almost always suffers some kind of issue in major lightning storms. It trips a breaker at the base. The drive out is 20 minutes and worth while compared to having to climb the tower when the storm is over. We do not use UPSs anymore on the large deployments. The DC box stays on the ground because the power line going up the tower is either fused or has it's own DC breaker. We also have a site monitor at the base to monitor voltage levels on the batteries and we can graph the stats to troubleshoot in the future. Because we use a breaker or fuse in our DC system going from the top to the bottom, it would be a pain to still have to climb to replace a fuse if necessary.

We have a site that needs converted to DC and recabled, and are considering this route. Our thinking is, why put the dc box at the bottom when we can just put the thing up at the top and run nothing down to the bottom except power. All our backhauls are half way up the tower, no reason to even have anything at the bottom except the UPS. What type of fiber are you guys using for attaching to the tower? We will need to run a fiber from 1 level to another on the tower to feed the backhauls to the APs, and are unsure which type fiber cable to look at. Should we use armored fiber and just ground the jacket to the tower on each end, or do we want fiber with no metal jacket so that it's not conductive?

We send 48v DC up to the top and downconvert. I think we've gone about 450' with this configuration (including up the tower and along the cable raceway to the inside of a building) However, that's primarily why we send 48v up and downconvert, because of the voltage loss. Gives very clean 24v power to the equipment. http://www.amazon.com/Cable-Portable-Power-Gauge-Conductor/dp/B0076ZT4C2 It would probably be better for me to take a picture of one of our boxes. We are continually building them as we continue our wireless upgrades. I don't remember if Gerard resub'd to this list after it moved, but he's the engineer behind the box. He can give you parts.
