Abstract: An optical network terminal (ONT) is powered via a remote power supply. The remote power supply is connected to a standard customer premises electrical power outlet, providing a power source for power at a first format (e.g., 110 VAC). The remote power supply performs a power transformation to convert the power in the first power format to a second format (e.g., 48 VDC). This allows the powering of the ONT from farther distances, and thus allows for the easier installation of ONTs at customer premises which may not have optimally placed power outlets. A battery backup may also be used (either in parallel or serially), in order to provide availability of communications signals during a public power outage. When the battery backup used serially with the remote power supply, additional distance between the power outlet and the ONT may be accommodated.
