I'm making a plan to connect two buildings over Ethernet that are at least500 feet apart. I'm thinking of using fiber optic cable because of the distance. I think I want multimode fiber with sc/sc connectors. I'm not sure if the network I'm upgrading has gigabit Ethernet fiber optic support, so I want to use two TRENDnet 1000BASE-T to 1000BASE-SX Fiber media converters at either end. Furthermore, I want to run the fiber optic cable through a tube in the ground.
Is this a good plan or should I try something different?
