All you need to know about FDDI is that it is great and Ethernet sucks even
though it has taken over the world. ;) When you get the proper cabling the
thing will just start working, all the info about monitor stations and token
expiration and ring reversal you shouldn't need to deal with for your
situation.

Technically it's closer to a MAU, but they are generally called hubs or
concentrators - basically it's a "ring in a box" that injects and removes
loops for the stations you plug in. On ebay I'd just search for FDDI. ;)
