We have been on a 'full fibre' service for a year or so now...
except that....
we are still on a copper pair from the cab
We had that for a year or two, fibre from the exchange, to the cab, then translated by the cab, for the copper final half mile. It permitted slightly higher speeds, and higher reliability. Prior to that, and for many decades, we had copper all the way.
Then a fibre company came along, and added a fibre access point at the end of every drive. I inquired about the cost of moving to fibre, but the cost was ridiculous, so I didn't bother.
My copper 40Mbps provider, Plusnet, kept on increasing their charges each year, but along came CityFibre/Youfibre, promising a much cheaper option, with a switch to fibre, and 150Mbs each way, so I accepted their offer earlier this year, along with porting my number to fibre. I get a consistent 150+, and cheaper, so no complaint from me.
I now, like many neighbours, have two lines from the pole, the fibre, and the redundant copper line.
