|Ok, in my first response I stated that you'll probably want to use Single Mode between buildings.|
Single Mode has the longest maximum segment length (up to about 25 km's/15 miles). You might be able to find multimode that will span the distance you need to but the longer your segment of multimode is, the lower the bandwidth on it gets. Do some research and if necessary, make a few calls. All the information and specs on the different types of both Single/Multi mode cables is easy to find. You may find 10 GBps capable multimode cable that will operate at full capacity over a 500 meter run.
What I can tell you is that internally between wiring closets we use multimode for our backbone. For the other buildings on our property that are physically some distance away (50 m, 100 m), we use single mode. In both cases, we terminate the fiber optic cable to a "fanout" box as our switches all have GBIC's. Then we use a short fiber optic cable between fanout and switch to connect it. In both cases (patch cable and long run) the fiber optic cables are preterminated/tested/certified.
If you go with media converters at each end, or GBIC's, those are your transmitter/recievers.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
