Yes, but indoors the optical network termination needs a power supply, so as you say if you have some form of UPS, you may be all right.
It seems that BT has a battery option for their ONT (Fibre interface box) - and you can connect a conventional phone direct to the ONT. https://www.openreach.com/content/dam/openreach/openreach-dam-files/images/news-and-opinion/articles/2018/02/ONT%20Factsheet.pdf
The problem seems to be that the battery only last for a short time (tens of minutes) so is useless for longer power cuts (as often happens after major storms, or as in my case when the old PILC cable in the street went phut) - so failing to provide a proper means of being able to make emergency phone calls during a power cut.
So as a minimum could we have a small battery (perhaps kept charged while the power is on, or just a simple long-life battery) which was available, but not actually used immediately the power fails - and then the procedure for making an emergency call using a conventional corded phone during a power cut would be 1) throw a switch to connect the battery, 2) wait for the ONT to re-establish a connection with the exchange, 3) dial as normal.
