My business is fiber broadband, and we are laying as much as we can! Fortunately the legislative environment in the UK is conducive to this goal. For now we provide XGS PON (10Gbs minus overhead), with 50G PON becoming available in some locations later this year. Unlike regular point-to-point, it is point-to-multipoint through the use of optical splitters with one head-end port capable of servicing up to 256 clients. With the UK being so far behind most other developed countries, it means it can take advances in all of the R&D from the last twenty years. It has also led to the strange situation where there are some properties that have a choice between 4 or even more fibre network providers. Some fiber networks are tied to a single ISP whereas others are open to wholesale. I am not sure if there are any ISP's that support multiple connections to the same property via different fiber networks - but I think you would generally want to use a different ISP for each network anyway. IPv6 is supposed to make that easier, though in practice there are still no protocols (a la MEF 17 Service OAM) for the ONT to signal to the router that there is a fault condition. This is one circumstance where PPPoE is useful. As the UK has been slow to deploy fiber there are many ISPs still using it. I found this out the hard way when I made the switch. My trusty old Ubiquiti Edgerouter Lite (Cavium silicon) is not capable of hardware offload for ipv6+pppoe+vlan at the same time, so anything particularly demanding on IPv6 (e.g. Steam) essentially locks up the router. I will be trying out an Alta Labs Route10 this week to see if it provides any improvement.
