By the way I have an FTTH to ethernet converter that I don't use anymore, if you can use FTTH but I see VDSL so not sure you could use it, depending on your service provider option.
If interested it's a TP-Link MC220L with a TL-SM321B (1000Base-BX WDN Bi-Directional SFP Module).
Nobody want it in Switzerland because it's limited to 1Gbit/s but all provider offer 10GBit/s now.

If you or anyone is interested I can sell it for cheap, I have to check shipping cost in EU.
