Devices and systems for providing reduced cost and increased reliability power line communications (PLC) and electrical power to a network device using a PLC supply unit via a single cable with 2 wires are disclosed. The PLC supply unit receives a PLC power and data signal, extracts the power signal, the data signal and generates a timing signal based on the power signal. The PLC supply converts the electrical power signal from an alternating current (AC) to a direct current (DC) electrical power signal and then recombines the DC electrical power signal with the data signal and the timing signal and sends the composite signal to the network device. The network device receives the composite signal and uses the DC electrical power signal to power the network device and, at an internal PLC processing module, processes the data signal for communication with other network devices using the timing data.
