Hi @Somesh
I understand. Then there must be a connection somewhere else in your home where this photographed cable is connected. Possibly this Ziggo outlet can be found in the place where the fuse box is located. When you have found the outlet, take a picture of it.
But now that I've looked more closely at the photo, it looks a lot like a Ziggo cable and these are often no longer than 1.5 meters. It is therefore possible that the cable is neatly hidden in the wall and that the connection is somewhere behind a cabinet. 😦
Tomorrow a moderator will probably visit this topic, otherwise you can make an appointment by phone or via chat with the helpdesk.
