Can I buy a replacement power supply for my BT Fibre socket ?

Hi all,

so we just moved from our rental to our first house and in the moving process I've no idea where I have placed the wires that came with it when I had it at my previous address. So I don't have the power supply that goes into the BT openreach fibre socket and the cable that goes from the socket into my hub. Is there anywhere I can buy a generic replacement for these two things and if so what are they called ?
