Which statement correctly describes 802.3bt PoE++ Type 4?

• A. 802.3bt PoE++ Type 4 delivers higher power than Type 3.
• B. Type 4 reduces the power compared to Type 3.
• C. Type 4 is not related to copper cabling.
• D. Type 4 uses fiber.

Answer: (A)

802.3bt PoE++ Type 4 is about delivering more power over the same copper Ethernet cabling than the previous PoE++ generation. It uses all four pairs to push higher wattage to the device, enabling power-hungry equipment like advanced wireless access points or high‑power IP cameras. In practice, Type 4 can provide around 90 W to the powered device, with the power sourcing equipment capable of delivering up to about 100 W in some setups, which is notably higher than Type 3’s maximum. This is why the statement about delivering higher power than Type 3 is correct. Type 4 remains copper-based (not fiber) and is not about using fiber.
