Salt[1] in Switzerland has been offering 10Gbps FTTH for half a year. Maybe Bahnhof's router is better, but it's certainly not the first.
That being said, I think Banhoff was claiming to be the first in Sweden, not worldwide.
Besides their customer service is horrendous.
As opposed to a dedicated direct 10 gigabit line to every other internet device? Everything is always shared unless you request a dedicated circuit between a given set of points. Sometimes the over subscription ratio is just shit, which is a real thing to complain about.
Salt uses 10G-PON, which as I understand it splits a single 10Gbit port. Salt's configured to split it 64 ways.
It's possible other providers are oversubscribed upstream but I haven't personally experienced any congestion issues with Init7, even over long distances (e.g. Zurich to Fremont, CA).
[0] 80.- per Month
I do recommend Init7, but in the meantime Wingo would be a bit cheaper for you, and I believe that Sunrise is available everywhere (they use Swisscom's network where they don't have their own access points). Yallo is currently offering a deal for 35.-/month.
(you can get 250/100 but that caps you at 3TB and costs $250/mo)
EDIT: scratch that, it’s up to $51bn
