I would use 14-2 UF cable, direct buried next to the fiber, or pulled into conduit with the fiber if you are doing conduit. That's going to be much cheaper than SOOW type rubber jacket cable, or pretty much any other options. 1000ft spool costs us about $250, and there are direct bury splice kits for it to make a waterproof buried splice.
