The goals of these BASE-T projects are specifically to extend the life of the large installed base of Cat 5e/6 cabling with higher speeds. I wouldn't expect there to be a fiber interface, because we already have much higher speeds that are supported on MMF/SMF at better costs (ie if you had a fiber cable, would you really want to run 2.5 GE when 10 GE is so affordable now). Anything is possible though, if there is enough demand and a market then someone will make it.
