They use both though, they use VM in areas where they have a presence (mostly their cabled areas). Most transmitters still rely solely on BT fibre though.

Vodafone (C&W) arguably has a bigger Core Fibre Network than BT and Virgin Media's isn't too shabby either.

Dark Fibre, or wholesale of fibre is freely undertaken between operators on commercial terms and is in no way equivalent to the access to the " last mile" which is what open reach was all about.

There's fibre speed.

That's incorrect. MBNL uses VM small bits will use BT tails but the vast majority is VM

Vodafone used to use NTL (VM) then they moved to Global Crossing (level 3) then they bought C&W

VM has a vast nationwide network, yes they only provide broadband services to their " cabled" areas where they have Access Network but their core fibre network is huge.



It's actually the other way around, VM and Vodafone will use the odd BT tail but only a few, and they use them to link into their own fibre networks not BT's

I don't know how you can claim this though. I live in an urban area but I only see Virgin Media jointbox covers in about 60% of that area (I am including their core network and you're right I've seen Nynex ducting on main roads in areas they don't serve with the cable network.

Also in the case of C&W you missed off Energis, which like Norweb has the vast majority of its fibre overhead on its electricity pylon network. Also everybody, except BT, already share their infrastructure.

Same as above, Vodafone and it predecessors, don't have access networks so they don't have chambers on every corner everywhere. Just on their Core routes. Also in the case of C&W you missed off Energis, which like Norweb has the vast majority of its fibre overhead on its electricity pylon network.

Also everybody, except BT, already share their infrastructure. VM has fibre in Vodafone ducts, Level 3 ducts etc and vice- versa and have done for decades, they also lease dark fibres to each other on a commercial basis.

I didn't say they didn't but it's a lot less than you might think, and it's not BTs core network they would use if at all possible but fibre tails in their access ducts.

Many remote masts are connected by micro wave links and not cables.

Other examples I can give are Cumbria for example, there's mobile masts fed in remote parts of Cumbria where the fibre is run along the west coast mainline, then a dig of a couple km to the mast.

Fed completely independent of BT. You only would see a few VM chambers, if they weren't grown over.

Other instances similar instances are masts fed from core fibre run along canal towpaths.

There are loads of solutions to feed masts without having to go to BT, and if you had a wide knowledge of the sector you would know that without going to the default " it must be BT " stance.



You assume wrong, I've built and maintained VM's ( and forebears) networks for nigh on 20 years. I have intimate knowledge of its and other carriers fibre footprint.

Interesting post I'll grant you that. Could you explain what you mean by "fibre tails in BT's access ducts". Surely if they have BT fibre connected to the mobile masts then it'll be going back to a BT exchange? (as they don't share ducts). Do you mean that at the exchange it then switches to another provider's core network?

You have an "interconnect" or "meet-me" chambers where you have a handover. Virgin Media run a fibre to this chamber then it is jointed onto a BT fibre and run to wherever, a mast or an exchange. These tails are generally less than a km or two in length.

So the traffic doesn't go via the BT Core but straight onto the VM Core.

But there are other combinations as you suggest. In really outlawing areas where there is absolutely no way of getting onto any VM fibre, then the traffic can be taken back to the BT exchange and VM can pick it up from there.



There can be lots of reasons, but just because there is BT fibre running into that mast doesn't mean that BT are the sole carrier serving that site. There may be other fibres running into there.
