Which device in a passive optical network PON doesn t require electricity
Since the optical splitters require no external power, there is no need for active electronics or cooling systems between the central office and the customer. This lack of powered equipment drastically reduces ongoing operational expenses related to electricity consumption and site. A passive optical network (PON) is a fiber-optic telecommunications network that uses only unpowered devices to carry signals, as opposed to electronic equipment.
