The power line communication system includes a distribution transformer having an electrical power feed cable for providing electrical power and having at least one distribution node connecting a plurality of clients to the electrical feed cable. A high speed (HS) head end is electrically disposed at the client distribution node and the feed cable passes through an isolation filter at the client distribution node to remove any high frequency modulated signals and to provide an isolated electrical feeder cable output. A HS head end HS power line communication (PLC) modem injects HS communication signals into the isolated feed cable. This PLC modem receives HS signals from a backhaul communication network and the feed cable branching to each client premises. A HS PLC modem located in the client's premises to extract the HS signals. The isolation filter electrically isolates any HS modulated signals from travelling back to the transformer side.
