He didn't say coax cable. He said 10Base2/5, which are Ethernet technoloiges that use coax cable. I don't think you can run FDDI over coax cable. (Consider what the F stands for! ;-) CDDI supports FDDI's MAC layer using UTP cabling.
Reading between the lines, I think he is trying to get some FDDI practice on a router that only has Ethernet interfaces. This would be like trying to take an airplane from a train station. In some (mostly non-USA unfortunately) cities, there are terminals that support both airplanes and trains. In some networks, there are devices that support both FDDI and Ethernet. They are called bridges, switches, or routers.
