My new second job is in the end stages of putting fiber optics between
buildings. My understanding is they are running two fiber wires. One
for transmit and one for receive (however I may be mistaken). According
to the guy who installed it they are splitting one of the wires for a
maintenance shed. If I understood him correct they are going to split
one of the two wires and use a media converter.

I know squat about fiber optics. I was told they need a switch for two
of the buildings and a media converter for the maintenance shed.
Somebody please give me a quick crash course in how fiber works. PLEASE!!!
