This reminds me a bit of the situation we had in Zurich. The (city owned) electric utility had a few hundred million reserves and decided to invest it into a fiber network. Actually - since the utility was owned by the city - the decision was based on a popular referendum, which sailed through. Needless to say that the established telcos and cable providers fought tooth and nail to kill the referendum. The interestin…
> The network is managed, and I think wisely so, in a way that EWZ grants equal access to private ISPs which then compete for customers. They don't act as an ISP. This is the model I see as ideal and it always baffles me why it's so rarely mentioned as an option. Make the fiber network a public grid like roads, water, sewer, power. Then sell access to private companies to deal with the connectivity, services (TV/VoIP…
But the thing is, as much as I'm absolutely for a similar model to this, the technology is not mature enough that we know how to make it work best. BT OpenReach is struggling to provide the same speeds as Virgin. They claim to be able to offer up to 100Mbps, or 150Mbps in some regions, but my provider which packages BT OpenReach fibre access does not advertise more than 80Mbps and often advises to expect less (I was told to expect no more than 66Mbps based on distance from the cabinet because despite BT OpenReach's claims, they very rarely manage to meet it. Meanwhile Virgin reportedly have no problems reaching 100Mbps.
Without competition, there'd be little incentive for BT OpenReach to try to resolve the issues limiting their bandwidth. As it is, it matters so much that they keep misleadingly claiming they can deliver more (and many ISPs echo their claims).
I'd argue that while it is important to have a "baseline" provider that is required to offer 100% equal access, it is still important to provide wider access. There's really little reason not to require that every time a cable duct is put down to the local cabinet, that extra strands of fibre are laid down, for example, so other operators can rent dark fibre and install their own equipment. Or that cabinets be made big enough to accommodate some extra equipment for a small number of additional providers (and put similar access requirements on these providers, given that space in the cabinets will still be at a premium).
Today in the UK, other providers can put equipment in BT's exchanges, but apart from the densest city cores there's no practical way for them to provide connections to the end-user premises other than for Virgin (which is only in that situation because they merged UK's last two large cable providers who each had spent many years gobbling up smaller operators, often at bargain prices as competition got fierce, and had already written off most of the cost of building out the physical infrastructure).
It isn't necessary to have 10 providers all operating their own equipment and their own fibre, but there's little practical reason not to make space for at least 2-3 providers all the way to the local telco cabinets (even if not immediately), and allow the subscribers connection to be reconnected to the equipment of any of these based on the subscribers wishes.
