Answer for Fibre optic wireless router?

There are many routers that will support 100 Mbps and PPPoE. The fact your connection is fibre optic should not matter. However, if you are asking about 1000 Mbps (gigabit) then that is a much tougher question, as most routers are not necessarily designed to move that much bandwidth. Some of the high-end routers of today can probably move that much data, but there is little testing available to prove for certain.
I suggest discussing with your ISP if there is anything special you need on your end to support your Internet connection, as I suspect your service isn’t too much different than most Internet services.
