PoE technology is a popular power supply solution for modern network devices. It is widely used in businesses, smart homes, and security systems because it is convenient and efficient. Among the many PoE standards, PoE++ (IEEE 802.3bt) is undoubtedly the most advanced and powerful choice.
Why choose Power over Ethernet++ (IEEE 802.3bt)?
PoE++ represents the newest PoE technology generation. It can provide more power than the previous generation standards. This helps meet the needs of high-power devices. The PoE++ standard is further divided into Type 3 and Type 4, among which:
Type 3: can provide up to 51W of power on two or all four twisted pairs.
Type 4: can provide higher power on four twisted pairs, up to 100W.
The rise of PoE++ has greatly increased how we use Ethernet power supply technology. It is now good for high-end wireless access points.
Comparison of PoE, PoE+ and PoE++
To understand the advantages of PoE++ more clearly, we can compare it with the earlier PoE and PoE+:
