I heard that a few years ago the people in Zurich voted that everyone gets FTTH. So the network is now provided by ewz, the local electricity company, or by Swisscom and almost every household is about to get an OTO wall outlet with two possible fiber ports. You can choose between a number of professional and consumer-grade ISPs, so they don't even lock you in. The ISPs either give you a typical fritzbox CPE and/or a media converter (like the TP-Link MC220L), but it also works fine with the mentioned SFP. I now have 1Gbps Internet, fixed IPv4+v6, simply with DHCP (dhcp6c is needed to get the assigned IPv6 prefix for reassigning it to rad(8) internally). At least one (consumer-grade) ISP even offers 10G, at least theoretically, but I didn't dare to try them out. Reyk
