A PoE++ switch is a network switch compliant with the IEEE 802.3bt standard that delivers up to 100 watts of power over Ethernet cables. It powers demanding devices like advanced Wi-Fi 6 access points, PTZ security cameras, and video conferencing systems, simplifying installation by reducing the need for separate power supplies.
What Is a PoE++ Switch and How Does It Work?
A PoE++ switch supplies both data and up to 100 watts of electrical power through a single Ethernet cable, adhering to the latest IEEE 802.3bt standard. It utilizes all four pairs in Cat5e or better cables to increase power delivery. This allows it to support high-performance network devices, streamlining deployments by removing separate power needs.
PoE++ switches detect the power requirements of connected devices automatically and supply the correct wattage, ensuring compatibility with older PoE and PoE+ devices. This makes them versatile for mixed-device environments.
How Does PoE++ Compare to PoE and PoE+?
PoE++ delivers significantly more power than PoE (802.3af, up to 15.4W) and PoE+ (802.3at, up to 30W). There are two PoE++ types: Type 3, supplying up to 60W per port, and Type 4, going as high as 100W. This enables support for power-hungry devices that earlier standards cannot handle.
| PoE Type | IEEE Standard | Max Power Per Port | Power to Device | Cable Pairs Used | Typical Devices |
|---|---|---|---|---|---|
| PoE (Type 1) | 802.3af | 15.4W | 12.95W | 2-pair | VoIP phones, simple IP cameras |
| PoE+ (Type 2) | 802.3at | 30W | 25.5W | 2-pair | PTZ cameras, advanced IP phones, Wi-Fi 5 APs |
| PoE++ (Type 3) | 802.3bt | 60W | 51W | 4-pair | Multi-radio APs, video conferencing systems |
| PoE++ (Type 4) | 802.3bt | 100W | 71.3W | 4-pair | Laptops, flat-screen TVs, Wi-Fi 6 APs |
Which Devices Require a PoE++ Switch?
Modern, power-intensive equipment typically demands a PoE++ switch. Examples include Wi-Fi 6 access points with multiple radios, pan-tilt-zoom (PTZ) security cameras, video conferencing systems, and even laptops or flat-screen monitors. Devices needing more than 30 watts cannot be efficiently powered by PoE or PoE+ switches.
PoE++ is vital in industrial and enterprise environments where advanced networking and surveillance devices are prevalent, making Predision’s industrial-grade PoE++ switches a reliable choice for these applications.
Why Is Backward Compatibility Important in PoE++ Switches?
Backward compatibility ensures that a PoE++ switch supports older PoE and PoE+ devices without problems, automatically adjusting the power delivered. This protects legacy equipment while allowing seamless integration of newer, high-power devices.
Predision prioritizes backward compatibility in all its PoE++ switches, enabling clients to upgrade their network infrastructure gradually without replacing all existing devices simultaneously.
How Does Cabling Impact PoE++ Performance?
PoE++ uses all four twisted pairs in an Ethernet cable to deliver higher power. While Category 5e cables can support PoE++, Cat6 or Cat6a cables are recommended for installations with dense PoE++ devices or longer cable runs. These cables minimize heat buildup and ensure stable power delivery.
Selecting appropriate cabling is critical for network longevity and performance, especially in industrial contexts where Predision provides customized cabling solutions tailored to harsh environments.
| Cable Type | Max Data Rate | PoE++ Compatibility | Recommended Use |
|---|---|---|---|
| Cat5e | 1 Gbps | Yes | Short runs, low-density setups |
| Cat6 | 10 Gbps | Yes, recommended | Medium to high power devices |
| Cat6a | 10 Gbps+ | Yes, highly preferred | High-density, longer distances |
When Should You Upgrade to a PoE++ Switch?
You should consider upgrading if your network devices require power above 30 watts, such as latest Wi-Fi 6 access points, advanced PTZ cameras, or multi-radio video conferencing systems. Also, if your network is scaling or preparing for future power-hungry deployments, investing in a PoE++ switch future-proofs your infrastructure.
