1. A power source equipment (PSE) network device comprising:
a power over ethernet (POE) port for receiving and connecting to an ethernet cable for carrying DC power to a device connected to other end of the ethernet cable; and
a POE injector connected to the POE port, wherein the POE injector is configured to introduce the DC power from a DC power supply onto the ethernet cable, wherein the POE injector includes a modem and a transformer that are configured to:
modulate first perturbations into the DC power, wherein the first perturbations are longitudinal common mode signals for the device connected to other end of the ethernet cable; and
demodulate second perturbations in the DC power, wherein the second perturbations are longitudinal common mode signals from the device connected to other end of the ethernet cable.
