Just moved into a property where it seems I'm the only one of my neighbours with the white twin drop cable.. everyone else has new black single cables. The house has never had FTTC only ADSL in the past apparently, will this cable affect my FTTC sync? This is what it looks like. Twin cable
Does that cable run all the way to the nearest telephone pole?
Don't recall seeing white drop cable like that ever before, GPO/BT/Openreach cables usually have markings to identify them.
A non twisted pair cable if a significant length may affect the VDSL2 performance, a lot depends on how bad the RF noise is in the area, or put another way you will only know until you try the service out.
