Only in a small number of places is there fibre optic cables to the premises and even then they are connected to a ‘converter box’ that changes the cable to a coax that is then fed to your VM hub and TV box. Why do you think fibre is required. Coax can certainly do 1G and even a lot higher.

Fibre to the home (FTTP) is a specific physical connection which consists of running fibre optic links directly to the home where they terminate into a small 'converter' box and from there you have ethernet into the rest of the equipment. VM do have a FTTP service but it's only available in a very few specific areas, the vast majority of their customers (including you by the sound of it) are connected using copper co-ax cables back to a street cabinet, what is sometimes referred to as HFC (hybrid fibre-coax).
So the answer to the question is no, your existing cable can't do 'fibre to the home' because it's not the same thing.
