My neighbor has a big system box of jio, does anybody knows what it is? The wires(different colors) goes right into the ground and it runs 24/7 even when there is no electricity.
Can you click a picture ? I can tell you what it is.
Also, I have jio gigafiber in my apartment and there's no power supply or anything to it. There are just underground cables coming into my building (They have RJIL OFC written on the ducts) and a junction box that sends fibre cables into flats.
