I have ran fiber up a tower before. Typically I only do it for one of two reasons...
1. Long run (Ethernet is 100m)
2. Powered tower and do not want RF to enter my data transmission
I use armored fiber cable and usually bring it into a NEMA enclosure through a waterproof gland and terminate it normally.
I am not sure if I answered your question. If you need both power and fiber, I saw an ad in a publication I get for Senko (senko.com) that sells connectors that may help you terminate fiber and power (they may also provide cable).
Feel free to message me, I will help if I can.
