Undersanding Power over Ethernet: PoE vs. PoE+ vs. PoE++

PoE vs. PoE+

PoE (Power over Ethernet) and PoE+ are both standards for delivering electrical power to network devices over an Ethernet cable, but they differ in terms of the amount of power they can deliver.

PoE (IEEE 802.3af) is capable of delivering up to 15.4 watts of power per port, while PoE+ (IEEE 802.3at) can deliver up to 30 watts of power per port. This means that PoE+ can provide more power to devices that require higher power consumption, such as high-end wireless access points, IP cameras with pan-tilt-zoom (PTZ) capabilities, and VoIP phones with multiple lines and features.

Another difference between PoE and PoE+ is their compatibility with different network devices. PoE is backward compatible with devices that support the 802.3af standard, while PoE+ is backward compatible with devices that support both 802.3af and 802.3at standards. However, not all devices are compatible with PoE+ due to the higher power requirements, so it's important to check the specifications of your devices to ensure compatibility.

Overall, PoE+ is a more advanced standard than PoE and provides higher power capacity, but it may also require more power supply and equipment, which could increase costs.

PoE++

PoE++ (IEEE 802.3bt) can deliver up to 60 or 100 watts of power per port, depending on the implementation. PoE+ is backward compatible with devices that support both 802.3af and 802.3at standards, while PoE++ is backward compatible with all previous PoE standards.
