Power over one-pair Ethernet approach

摘要

A power over one-pair Ethernet approach. A data transformer is coupled to a single conductor pair using one or more direct current (DC) blocking elements that preserve an alternating current path. The data transformer enables a network device to transmit and receive data with a link partner device via the single conductor pair. Power transmission over the single conductor pair is enabled through the coupling of a power over Ethernet module to the single conductor pair using a diode that can be paired with a zener diode.

1. A system that enables power delivery over a single conductor pair to a powered device, comprising:
a data transformer having a first end and a second end; a first direct current blocking element having a first side coupled to a first end of said data transformer, and a second side coupled to a first conductor of the single conductor pair; a second direct current element having a first side coupled to a second end of said data transformer, and a second side coupled to a second conductor of the single conductor pair; and a power over Ethernet module coupled to said first conductor and said second conductor of the single conductor pair via a diode and a zener diode pair.
