Let's say I had to connect a pair of IP-based devices which are 800 feet apart, outdoors. Assume a wireless link is not possible, and that bandwidth requirements are in fact minimal.
Would it be easier, more reliable, and/or cheaper to use Cat5 twister pair, with an active repeater box every 250 feet such as this:
... or would it be more preferable to run fiber optic cable with a transceiver at each end?
Again, this is to reach a few low-impact devices so I don't need high throughput as long as it's reliable. At first I feared Ground Loop issues with copper (I grew up in the audio field) but it appears my assumption was wrong as twisted-pair is transformer-isolated and therefore immune by design. But I also suppose that fiber would eliminate any RF issues as well as minimize catastrophic losses due to static electricity or lightning.
Am I missing anything that significantly points to one or the other?
