To answer your first question, early cable networks tended to be MATV systems that eventually joined up (as far as I can tell) - and they had their own little headends and there was no fibre.

Once those networks began to join up, I would imagine that the technical sites / local head-ends were linked to each other fibre (carrying an analogue signal at 1550nm) since that has been available for many years. I know it was fibre-to-the-grid-square in Western MK because I've seen it physically - but I think after that point, it was a set of daisy-chained copper running under the lawn between houses using cheaper co-ax, just like the MATV systems of the 80s.

Maybe someone from BT or Openreach knows more about the physical architecture of the MK system for historical purposes - obviously it's dead, now.
