Kade, I can't speak on the fiber, because we have used a few different kinds over the builds we have done. 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.
