1. A wireless communication device configured to be used with a photonic service demarcation device including a debug interface, the wireless communication device comprising:
a low power communication module;
a power supply module coupled to the low power communication module;
wherein the power supply module comprising:
a power supply configured to supply power to the low power communication module;
a comparator coupled to the power supply;
an input buffer comprising an energy storage, the input buffer being coupled to the comparator of the power supply module; and
a diode coupled to the input buffer and a transmission (TX) signal line of the debug interface, the TX signal line of the debug interface being configured to transmit data,
wherein electrical energy is harvested from the TX signal line of the debug interface and stored into the energy storage via the diode disposed between the input buffer and the TX signal line of the debug interface, and
wherein the comparator of the power supply module is configured to:
enable the power supply to supply power to the low power communication module when an amount of energy stored in the energy storage reaches a minimum threshold of energy stored, and
switch off the power supply to the low power communication module if a power demand is not sustainable or runs the TX signal line of the debug interface above a predetermined minimum space voltage.
