During construction I included a length of fiber optic cable that could be used to interconnect Cisco Catalyst 2900 switches that I picked up for $20 apiece at a swap meet. In this picture you can see where the fiber optic cable terminates next to the shop electrical sub panel. The hooks inside the electrical box used to coil the excess fiber optic cable and prevent it from bending and breaking the glass filament were made from a cheap plastic hooks designed to hang from the top of a door.
