In reply to a post by deeor:

I have taken a couple of photos of my local cabinet(s).

Does the metal one look like a fibre cabinet?

At the time it was installed, many months ago now, there was also extra cabling added to the ducts going back towards the exchange.

The plastic cabinet seems to be kept clear but the metal one looks as if it hasn't been opened for months.

My objective in asking about all this is to establish, before I approach BT, whether fibre might have been installed months ago but never connected to customers' copper.
