Power over Ethernet, or PoE, has been around for years and is becoming increasingly popular in homes and businesses. It’s now taking on a new form, known as PoE++. This new iteration of the technology has several advantages that make it ideal for smart network switches. In this blog post, we will explore what PoE++ is and how it can benefit your smart network switch. We will look at the advantages of using this technology over traditional methods, as well as any potential drawbacks you may encounter when implementing it. By the end of this article, you will have a better understanding of PoE++ and why it may be the right choice for your network switch setup.

What is PoE++?

PoE++ is the next generation of Power over Ethernet technology that can provide up to 100 watts of power per port. This makes it ideal for powering devices such as cameras, access points, and VoIP phones. PoE++ is also backward compatible with existing PoE devices.

How can PoE++ benefit your smart network switch?

PoE++, or Power over Ethernet PlusPlus, is a new PoE standard that provides up to 60 watts of power per port. This higher power level allows for more devices to be powered by a single PoE++ switch, including devices that require more power such as IP phones, video cameras, and access points. In addition, PoE++ can provide power to devices in harsher environments where traditional PoE is not sufficient. For example, PoE++ can provide power to devices in outdoor or industrial settings where temperatures may exceed the limits of standard PoE.

PoE++ can also benefit your smart network switch in other ways. For example, if you have a 24 port poe switch with 20 ports populated with PoE injectors, you would need 48 Watts of total power (2 Watts per port). With PoE++ you could increase the number of powered ports on the same switch while reducing the amount of overall power required. This could save money on your electric bill and reduce your carbon footprint.

What are the advantages of using PoE++?

There are many advantages of using PoE++ compared to other types of power over Ethernet technologies. Some of the benefits include:

1. Increased Power Delivery – PoE++ can deliver up to 100W of power, which is significantly more than the standard PoE delivers (up to 25W). This increase in power delivery can be very beneficial for devices that require more power, such as IP cameras or WiFi access points.

2. Higher Efficiency – PoE++ is up to 80% more efficient than standard PoE, which means less heat is generated and wasted energy is reduced. This makes it a much more environmentally friendly option.

3. More Flexible Deployment – With its increased power delivery,PoE++ can be deployed in a wider range of locations and scenarios than standard PoE. This flexibility can be very beneficial for businesses that have unique power requirements.

4. Cost-Effective – Although PoE++ technology is still relatively new, it is already becoming more cost-effective as production costs continue to decrease. This makes it a great option for businesses on a budget who still want to take advantage of its many benefits

How does PoE++ work?

As its name suggests, Power over Ethernet (PoE) is a technology that enables Ethernet-based devices to receive power from a PoE-compliant switch or injector. The 802.3af and 802.3at standards define two types of PoE: Type 1 supplies up to 15 watts of power, while Type 2 supplies up to 30 watts.

In order for a device to be powered by a PoE-compliant switch, it must support the same type of PoE. For example, an 802.3af-compliant switch can only supply power to an 802.3af-compliant device.

PoE++ is an enhancement to the 802.3at standard that increases the maximum power that can be delivered to a PoE-compliant device from 30 watts to 60 watts. This increase in power enables new applications for PoE, such as powering high-definition video cameras and displays, which require more power than what the 802.3at standard can provide.

The increased power delivery of PoE++ is made possible by using all four pairs of wires in an Ethernet cable instead of just two pairs, as is the case with 802.3af and 802.3atPoE. This allows for more current to be carried, which increases the amount of power that can be delivered over the same distance as traditional PoE technologies


PoE++ is a great tool to consider when looking for ways to optimize your smart network switch. It can provide more power than traditional PoE and has the added benefits of being less complex, more efficient, and less expensive. With its ability to save you time and money while giving you an easier way to manage your network, PoE++ is definitely worth considering if you need a reliable power source for your switch.
