I may have to run 1200 feet of fiberotptic cable and AC power cable. I would run PVC conduit in a trench with the fiber inside. I can buy pre-terminated non-conductive outdoor fiberoptic cables in this length range. But has anyone ever done such a long pull? I don't think it is advisable to break the fiber into shorter segments due to return loss, etc. I only need two strands of fiber, but I will probably buy cable with more strands just in case there is some need in the future. Six strands seems to be common.
Ideally I would like to run the fiber in the same conduit as the power, but this seems perplexing.
In order to manage pulling the copper wire, I think I will need to break it up into 300 foot runs with intermediate pull boxes. It seems like it would be extra work to pull the fiber through the segments 300 feet at a time. Also, some segments would experience extra friction. Basically, whatever is going into a conduit segment should be pulled all at once in one go, it seems to me. But this will be hard if the copper is in 300 foot segments and the fiber is one continuous run.
I could run the fiber through its own conduit, but if I don't need to do that, I don't want to. I mean, I am paying for the conduit. Also, seems like it would be a difficult pull. (Please comment if you have experience).
Anyway, if you have done something like this, please let me know what the best way to do it is.
I am adding this information because I think people will ask. The copper wire will be 240V (two hots no neutral). I will run AWG14 THHN wire. There is not much of a load up there, and the load can tolerate a very wide voltage range (down to 100V). Ampacity is fine and I can live with the voltage drop. Will also run a 14AWG ground wire. Will install ground electrodes at far end.
