There exist some VDSL2 SFP Bridge Modems. They do symmetric DSL up to 100Mb/s and support ADSL, ADSL2+ (Annex A/B/M), VDSL2, Vectoring (Annex A/B/C), VDSL Profile 8a/b/c/d, 12a/b, 17a, 30a.
You can get them as CPE and CO (DSLAM) mode.
All of the available modules seem to be the identical and you can get them from 100€. The CPE mode ones just work with Germany Telekom VDSL2 connections, but it can take some minutes until they finished syncing.
You just plug them into one free SFP port of a switch or router which got fixed to 1Gb/s module speed.
There are rumors about a management/statistics interface, but information yet.
A super vectoring (profile 35b) SFP modem is already invented but not available due to production capacities.
