Eight channel surge protection for power over ethernet solutions

摘要

Systems and methods are provided for 8-channel surge protection for a network utilizing Power Over Ethernet (PoE). Four Bob Smith terminations are arranged such that one Bob Smith termination is coupled to each of four PoE nodes. Each Bob Smith termination includes a capacitor and a resistor pair coupled in series between its respective PoE node and a respective Bob Smith termination node, wherein a first pair of the Bob Smith terminations is connected between their respective PoE nodes and a first Bob Smith node and a second pair of the Bob Smith terminations is connected between their respective PoE nodes and a second Bob Smith node. The first Bob Smith node is capacitively isolated from ground via a first terminating capacitor component and a second Bob Smith node is capacitively isolated from ground via a second terminating capacitor component separate from the first terminating capacitor component.
