What components would you imagine in such a bundle? I have the feeling that people's setups for Fiber7-X and especially Fiber7-X2 are very different.
For fibre7-X, a Zyxel AX7501-B0 + matching optics is sufficient. But you can currently get this from Init7 at a much lower price. For Fiber7-X2 there are many different variants. From self-built routers to MikroTik CCR2004-1G-12S +2XS (which apparently isn't the real thing either and doesn't get 25Gbit cleanly). Over time, the best/most suitable hardware variant would have to crystallise.
