The installer will probably run the fibre externally, clipped to the wall and enter the living room where the ONT is to be sited. You cannot run a fibre yourself.
Although you are struggling to post an image , what does it say, the pertinent part ( for a fully ducted home is ) ,
Our records show the following FTTP network service information for these premises:-Single Dwelling Unit Residential UG Feed with no anticipated issues.
What does your show ?
The ONT doesn’t have to go where the master socket is , occasionally the installation of the ONT cannot be where the customer wants it , because it’s going to be impractical or time consuming to put it there , but the installer will try to accommodate if the request is reasonable.
With some properties, if ( for example ) the ONT is required at the rear , but the new optical cable appears at the front , it would be preferable to run the cable on the outside wall from front to back , rather than surface mounted on skirting boards/ door frames, through various rooms , to get to the same location internally, but obviously this may not be possible, on terraced houses for example.
Thanks, it says:
Single dwelling unit residential ug duct rodded and roped
I’m in a mid terrace unfortunately.
So you can see the rope ( it’s not blue but white ) so getting an optical cable to here should be straightforward, it’s probable that the engineer will remove the existing grey ‘box’ (a BT66 ) , and replaced it with a CSP in the same place ( on top of the duct cover ) from here another optical cable is taken to the location of the ONT ( inside the property ) , the neatest job is to use the same ‘hole’ that the copper cable uses to get into the house ( you cannot see it because it’s behind/inside the BT 66 ) …..if you order FTTP it’s a single stage install ( because the duct is roped ) so on the day you and the installer would hopefully agree to where the ( internal) cable will be run to ,you won’t get a visit to discuss requirements and another later visit for the installation, the internal cable cannot be put under carpets , behind cavity walls etc and not be ‘miles’ away from where the cable actually enters the property….if you get a contractor ( rather than an OR engineer ) they cannot afford to take hours and hours on a single provide , but you won’t know in advance if it’s OR or a contractor that has your ‘job’.
