Abstract
A device and method for providing power line communications via an underground residential distribution power system is provided. One embodiment of the present invention includes a medium voltage interface device that may include a first port configured to communicate over the power line and a network interface. A first amplifier may form part of a first communication path between the first port and the network interface and be configured to amplify data signals transmitted via the first port. In addition, a second amplifier may form part of a second communication path between the first port and the network interface and be configured to amplify data signals received via the first port. In addition, the embodiment may include a diplexer forming part of the first communication path between the first amplifier and the first port and forming part of the second communication path between the second amplifier and the first port. The device may include an electro-optic converter coupled to the network interface to convert between electrical and optic data signals, wherein the network interface is configured to communicate via one or more fiber optic conductors.
