A surge protected broadband power line communication system is provided. The system includes a local module with a base unit and a remote module with an extension unit. Both modules include broadband surge suppressors adapted to be connected to an AC power line. The base and extension units are connected to the surge suppressors and transmit and receive broadband digital signals through the surge suppressors and over the AC power line. The local and remote modules also have RF isolator filters connected to the surge suppressors and surge protected AC outlets connected to the outputs of the isolator filters. The local module is connected to a source of broadband digital signals such as a cable modem. The system makes the cable modem available in every room in a home simply by plugging an extension unit into an outlet located in that room.
