Its hard to know unless you are watching the cab or have asked the isntalling engineers.
The copper connection will be a trench between the two cabinets, while fibre can be installed to the cabinet but not connected to the main spine.
Hence why i suggested keeping an eye on roadworks.org to see if their is further work- if not then the cabinet should go into testing and then accepting orders.
You could email Openreach and they would give a estimated date for the cabinet to go live, will take 7-10 days and add your phone number/address as they will ask for this.
