I have a Vodafone fibre connection: the optical network terminal and the router are connected to the mains power: in the event of a power outage, is there any point in connecting them to a UPS, or is the fibre network going to be without power so nothing will work anyway? - I recall with copper lines, all you needed was for the exchange to have power, not the lines in the street, but is this the case for fiber as well?
