DrayTek offers with the Vigor 166 from now on a modem for copper lines that can also handle fiber optic speeds. The standard called G.Fast supports on the last mile of copper cable (in reality up to 200 meters) much higher data rates than Supervectoring with its up to 250 MBit/s.
G.Fast was developed to transmit high data rates of over 250 MBit/s. G.Fast can transmit up to 1000 MBit/s over short distances according to the specification with 106 MHz, at 212 MHz up to almost 2000 MBit/s. These speeds decrease rapidly with distance, so the path from the transition point from fiber to copper should not be too far away. But this is no different from existing solutions (VDSL, VDSL2, Supervectoring).
So the Vigor 166 can be classified as quite future-proof, because a lot of fiber optic connections will probably not really end on real fiber but on copper. The advantage of the DrayTek model is also that it is also capable of VDSL incl. supervectoring. So if you still use one of these technologies, but want to switch to G.Fast in the future, you can buy this modem right now. For all those who still need ADSL support which this model no longer offers, there is still the DrayTek Vigor 165 (or as used alternatives the Vigor 130 or the 2760 as a complete router).
