Hi dnnyhoward,
The cable network such as VM is a different network all together.
BT Retail and other communications providers may be able to offer Superfast Fibre broadband to an area if available in that exchange area.
There are two types of Fibre broadband technologies being used at the moment. The main one is FTTC (fibre to the cabinet) and the other which is in trial in a few selected areas is FTTP/H (Fibre to the home/premises)
FTTC broadband (Fibre to the Cabinet) such as BT Infinity is a fibre based broadband service. Here fibre is rolled out of the local exchange to a new FTTC cabinet that will be near your PCP (Primary Cross-Connection Point). These cabinets are usually found on your street or on the edge of a village. The new FTTC cabinet will have broadband hardware inside it (RDSLAM [Remote Digital Subscriber Line Access Multiplexer]). The new FTTC cabinet will be linked to the PCP.
This means that your broadband now travels from the exchange to the FTTC cabinet by a fibre connection then from the FTTC cabinet to your property using the existing copper phone line. The broadband signal travels as VDSL or VDSL2 which currenlty allows speeds of upto 80mb.
As FTTC uses the existing copper line for the last bit of the journey, the further away you are from your FTTC cabinet the slower the speed will be.
If you have this FTTC broadband connection then an Openreach engineer will need to replace your Master socket to a Openreach VDSL Filtered Master socket and a Openreach VDSL Modem which will then connect to you BT Homehub.
So: Openreach VDSL Filtered Master socket >> Openreach VDSL Modem >> BT Homehub
FTTP/H (Fibre to the Premises/Home) broadband such as BT Infinity is a fibre connection all the way from the local exchange to your property.
The fibre will need to be installed all the way from the exchange to your property. The download speeds that you can currently get with FTTP/H is 330mbps but can increase in the future. This is currently only available to trial areas.

Hope that helps.
