Missing power adaptor for ONU box

I recently ordered VM and have the hub delivered today.

I have an optical outlet in the wall that goes to the ONU box which then connects to the hub with the supplied coax cable.

i am missing the power supply for the white ONU box, and not sure what spec the replacement one should be?

I have also had to order a new fiber optic cable from the outlet to the ONU box.

hopefully this will allow me to get started once I have all these.

thanks
