Firmina will be the longest cable in the world capable of running entirely from a single power source at one end of the cable if its other power source(s) become temporarily unavailable—a resilience boost at a time when reliable connectivity is more important than ever.
i was going to ask what good it is having a cable that has power, but not the data center behind it.
i guess the situation is that the fiber optic cable also has power cables running along it too, powering the repeaters, and it's the power cables that might break. in this case, having single ended power would be very useful.
i'm most curious to know how power is sent. is this 48V dc? higher? how much? kV?
