*'''PoE''' (IEEE 802.3af): Provides up to 15.4 W of DC power.
*'''PoE''' (IEEE 802.3af): Provides up to 15.4 W of DC power.
*'''PoE+''' (IEEE 802.3at): Provides up to 30 W of DC power.
*'''PoE+''' (IEEE 802.3at): Provides up to 30 W of DC power.
*'''Compatibility:''' Limited to devices that specifically support the fixed voltage provided.
*'''Compatibility:''' Limited to devices that specifically support the fixed voltage provided.
*'''Risk:''' Higher risk of damaging devices if the voltage supplied does not match device requirements.
*'''Risk:''' Higher risk of damaging devices if the voltage supplied does not match device requirements.
*'''Examples:''' Commonly used in simpler devices like small access points and basic IP cameras.
*'''Examples:''' Commonly used to power up some of the Teltonika [https://wiki.teltonika-networks.com/view/Passive_Power_over_Ethernet_(PoE) devices].

Active PoE is standardized, involves power negotiation for precise delivery, and supports a wide range of devices. 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.
