Understanding the Differences: PoE+, PoE++ Type 3, and PoE++ Type 4

In the world of video production and networked devices, Power over Ethernet (PoE) technology has revolutionized the way we power and connect our equipment. By delivering both power and data over a single Ethernet cable, PoE simplifies installations, reduces cable clutter, and enhances flexibility. As PoE technology has evolved, new standards have emerged to meet the increasing power demands of modern devices. In this blog post, we’ll explore the differences between PoE+, PoE++ Type 3, and PoE++ Type 4, and how they can benefit your video production setup. Interested in knowing more about PoE technology? Check out this blog that goes over the basics of Power over Ethernet technology.

What is PoE?

Power over Ethernet (PoE) is a technology that allows Ethernet cables to carry electrical power in addition to data. This eliminates the need for separate power supplies and reduces the number of cables required for networked devices. PoE is commonly used in applications such as IP cameras, wireless access points, and VoIP phones. The original PoE standard 802.3af, developed in 2003, only allowed for a maximum of 15W of power, but would continue to evolve and improve with time. Below we will briefly cover each PoE+ standard and their capabilities.

PoE+ (802.3at)

PoE+, also known as 802.3at, is an enhanced version of the original PoE standard (802.3af). It provides more power to connected devices, making it suitable for a wider range of applications.

  • Power Output: PoE+ can deliver up to 25.5 watts of power per port.
  • Voltage: Typically operates at 50-57 volts.
  • Applications: Ideal for devices that require more power than what standard PoE can provide, such as PTZ cameras, video conferencing systems, and advanced wireless access points.

PoE++ Type 3 (802.3bt)

PoE++ Type 3, also known as 802.3bt Type 3, is a further advancement in PoE technology. It significantly increases the power output, allowing for even more demanding devices to be powered over Ethernet.

  • Power Output: PoE++ Type 3 can deliver up to 60 watts of power per port.
  • Voltage: Typically operates at 50-57 volts.
  • Applications: Suitable for high-power devices such as multi-radio wireless access points, high-definition PTZ cameras, and digital signage displays.

PoE++ Type 4 (802.3bt)

PoE++ Type 4, also known as 802.3bt Type 4, is the latest and most powerful PoE standard. It provides the highest power output, making it capable of supporting the most power-hungry devices.

  • Power Output: PoE++ Type 4 can deliver up to 100 watts of power per port.
  • Voltage: Typically operates at 50-57 volts.
  • Applications: Ideal for ultra-high-power devices such as video conferencing systems with multiple monitors, large digital signage displays, and advanced networked lighting systems.

 

The Netgear M4250 series AV Line network switches are specially designed for AV over IP applications in professional AV environments such as corporate offices, education institutions and more. Equipped with PoE++ Type 4 compatibility, the versatile M4250 line presents a range of switches to accommodate different lighting configurations and power needs seamlessly. Ikan is proud to work closely with Netgear in developing compatibility with our PoE Lights, and we currently offer bundles of our Lyra POE LED Soft Lights with Netgear M4250 network switches included.

Key Differences

  • Power Output:
    • PoE+: Up to 25.5 watts per port.
    • PoE++ Type 3: Up to 60 watts per port.
    • PoE++ Type 4: Up to 100 watts per port.
  • Applications:
    • PoE+: Suitable for mid-range power devices like PTZ cameras and advanced wireless access points.
    • PoE++ Type 3: Suitable for high-power devices like multi-radio wireless access points and high-definition PTZ cameras.
    • PoE++ Type 4: Suitable for ultra-high-power devices like video conferencing systems with multiple monitors and large digital signage displays, studio lighting fixtures.
  • Voltage: All three standards typically operate at 50-57 volts, ensuring compatibility with a wide range of networked devices.

Why Choose the Right PoE Standard?

Choosing the right PoE standard for your video production setup is crucial for ensuring that your devices receive adequate power and operate efficiently. Using a higher PoE standard can future-proof your network, allowing you to add more powerful devices without needing additional power sources.
