1. A powered device interface assembly for a powered device in a system employing power over ethernet, the powered device interface comprising:
an opto-coupler electrically coupled with a microcontroller of the powered device interface; and
a telemetry circuit coupled with the opto-coupler and configured to generate encoded telemetry information for output via a single pin of the powered device interface for transmission to the microcontroller of the powered device, the encoded telemetry information including a start pulse width, a first data pulse width, and a second data pulse width, wherein each of the start pulse width, the first data pulse width, and the second data pulse width differs from each other of the start pulse width, the first data pulse width, and the second data pulse width, and wherein the opto-coupler is coupled with the single pin and is configured to electrically isolate the single pin from the microcontroller.
