I ran fiber between my house and detached garage (which also includes my office). Installed some large conduit so the preterminated fiber could be pulled through, ran it just like any other cable (trying not to bend it too much), and installed SFP modules in two Unifi switches. I'd never done anything with fiber before, and it was incredibly easy.

I opted to install twelve strands of single-mode fiber. It's insanely overkill (I'm only using two strands right now), but the cost difference was minimal.
