The normal new build process is the builder/ developer is provided with various Openreach ‘stores’ , one of which is an internal optical ‘Ezibend’ cable that the developer installs at first fix between the location of the ONT to the external wall ,( so behind walls hidden from view) this has a white outer jacket and a blue inner jacket , the blue inner jacket is around the optical fibre , the end of this Ezibend cable at the house wall end is left coiled for Openreach to cut to the appropriate length , strip and splice the fibre to an external optical cable at the grey CSP block on the outside wall , the end of the cable at the ONT has a green SC/APC plug that fits into the ONT .
Potential problems are , the developer damages the cable installing it , or leaves insufficient cable at either end , so it cannot be plugged into the ONT or there isn’t enough cable length to enable it to be spliced at the CSP .
Before the plot is ‘called off’ as ready for occupation, the Openreach site representative ( called a FBC , field based coordinator ) should check this cable has been provided properly, and if the developer has messed up , they get them to replace the internal optical cable.
The construction of these cables have a ‘rip cord’ used to strip the outer jacket ( insulation ) from the cable , it is between the inner blue and outer white jacket , but it’s not clear why this is an issue, if it snaps then stripping the cable can be difficult, if the cable is too short , splicing is impossible.
Openreach could provide a new Ezibend cable but only the developer can install it behind internal walls etc , if the developer won’t install the replacement cable because they would have repair or replace plasterboard walls , then the ONT would have to be in a different location and surface wired from the CSP , so this could make redundant any Ethernet cabling provided at the original ONT location.
It seems to me it’s the developer is who needs to resolve this
