Re: Clue

here is the math, lets assume 90v, since thats what a telephone rings at.
90 volts
0.0842 ohms per meter for 24 gauge
60000 feet, FIOS uses BPON, 12 mile limit from central office
90*(90/((60000/3)*0.0842))=4.8 watts

20000feet
90*(90/((20000/3)*0.0842))=14.4 watts

heck, I dont know how RF noise friendly this is, but if we use 2 wires, we can use earth return, and get 2 times what is there, add a 2nd pair, same thing

»fios ont power req

18watts with TV+internet+phone running (not on emergency power), emergency power will be less

so yes its feasible, you'll probably need a new ONT tho, I dont think the current ONTs are as optimized as they could be when running on emergency power, so I dont think it would be as simple as plug battery pigtail of BBU into adapter and 2 screw terminals on the other end of adapter.

Thank you. Probably the ONTs run on 12V or 6V (additionally downconverted to 5V) so some power conversion and loss will occur.
