I have a separate HG612 modem (in the UK) but I recently found the SFP module MT-V5311 which claims support for VDSL all the way up to Profile 30a (200/100Mbps). There’s more info at
Unfortunately I’ve not yet found a source for this magical item. Has anyone seen one?
Apparently they have some sort of partnership with SoftAtHome, so perhaps a driver exists out there somewhere.
(There’s also a g.fast module there, but here in the UK that would be only of academic interest…)
