In contrast, Passive PoE delivers a fixed voltage without negotiation, offering simplicity and lower cost but with increased risk of compatibility issues and potential device damage if not properly matched. | Active PoE is standardized, involves power negotiation for precise delivery, and supports a wide range of devices.
