Fiber optic gigabit network between buildings

[panic mode]

Hi everyone, I like to do my own research but I'm in pinch with time so I'm asking for help/advice: We have two additional buildings which are close to the main building and we want to network them. Idea is to use Gigabit ethernet, most likely fiber optic as both runs are a bit over 100meter. I've seen ethernet switches with fiber ports etc. I know that distances over 60-70km are possible with the right setup etc. We probably don't need media converter for such small distance so standard ethernet switches may do (maybe). So far it seams that 50micron multimode cable is way to go (should do 550m, when using 850-nm wavelength). Any suggesttions? Are outdoors rated cable available? Can they be suspended or need additional protection? How about terminations?
