PoE Vs PoE+ vs PoE++ by Novotech

Are you seeking the most efficient and cost-effective way to power and transmit data to your devices? Choosing the right Power over Ethernet (POE) technology for your project can be confusing and complicated. When powering today's advanced digital networks, POE vs POE+ vs POE++ is a conversation that must be heard. The decision on which one to choose can make a world of difference in network performance, cost savings, and energy efficiency. In this blog post, we'll explore what sets these technologies apart so you can uncover which best fits your needs.

What Is POE Switch? 

Power over Ethernet (POE) switches are network devices that combine the functions of a power supply and a network switch. Their capabilities extend beyond just supplying power. It provides a faster data transmission speed than a regular switch. POE switches are a great way to save time and money by avoiding the need for an external power supply and extra wiring. The power sourcing equipment is used to provide power to Ethernet-enabled network devices.

POE Specifications

POE switch is also called POE, type 1. These network switches have multiple ports that enable power sourcing equipment to deliver power over the same Ethernet cables as data. The specifications of POE, type 1 typically include a maximum port power of 15.4 W and a switch port voltage range of 44-57 V. The voltage range to the powered device is 37-57 V, with a maximum power to the device of 12.95 W. POE has twisted two pairs of cables used for transmission. It also supports various cable types like Cat 3 and Cat 5/5e.  

It is covered under the Institute of Electrical and Electronics Engineers (IEEE 802.3af standard). With POE, type 1, your network can have flexible power-sourcing options and high-speed data transmission capabilities. 

POE Applications

POE, type 1, is suitable for applications such as VoIP (Voice over Internet Protocol) phones, wireless access points, and security cameras. It powers IoT gateways and modems. Since the power requirements of these devices are relatively low, POE type 1 can provide sufficient power for them.

What Is a POE+ Switch? 

A POE+ switch is an Ethernet switch with Power over Ethernet Plus capabilities. This type of switch is built to the IEEE 802.3at standard, which allows it to deliver up to 25.5 watts of power over Ethernet cables.

POE+ Specifications

POE+ switch specifications include a port voltage range of 50-57 volts and a voltage range to devices of 42.5-57 volts. Type 2 switch has max power of 25.5 watts per port, with two twisted pairs for power and data transmission. Various cable types, including CAT 5 and Cat 6. With POE+, there is an improvement in device compatibility compared to the earlier POE standard, allowing power delivery to a wider range of network devices. 

POE+ Applications 

POE+ switch is often used in home networking applications to provide power and high-speed data communication for connected devices. It can be especially useful for smart home security cameras and other IoT gadgets that need power and an internet connection. POE+ switches are also used in businesses, particularly for VoIP phones, biometric sensors, RFID readers, and wireless access points.

The advantage of POE+ switches is that they provide a more efficient power delivery solution than traditional AC-based solutions, reducing power consumption and installation time. You can also run NetCloud platforms for connectivity purposes.

What Is a POE++ Switch? 

There are two types of POE++ switches: Type 3 and Type 4. They are more advanced than the last two POE switches (type 1 and 2). Their configuration conforms to IEEE 802.3bt switch standard and thus can power devices with high power consumption.

POE++ Specifications

The specifications of these two types are:

  • Maximum port power: Type 3 has 60W, while the Type 4 switch has up to 100W per port.
  • Voltage range: Both types have a port voltage range of 52-57 volts and a voltage range to a device of 41.1-57V.
  • Power to devices: The max power is 51W for type 3 and 70W for type 4.
  • Cable: Supports Cat 5 cables and higher with two or four twisted pairs. Patch cables are helpful for devices nearby, while Ethernet cables take preference for devices that are far.

The higher port power, voltage range, and power to devices ensure that the needs of digital projects are effectively met. 

POE++ Applications

The POE++ Type 3 and 4 switches are suitable for applications that require high-power devices, such as LED lights, digital signage displays, video conferencing systems, and Wi-Fi Access Points. These switches are essential in places where a high current is needed, such as warehouses or industrial sites. POE type 4 can power screen entertainment devices and laptops. POE++ switches are also useful in large-scale digital projects with multiple devices, such as interactive displays and touch-points, that require higher power consumption.  

How To Choose the Right Switch

Choosing the right switch depends on several factors. Considerations include existing network systems, environment and usage requirements, current network appliances like cellular routers (including their power consumption), location of devices, desired system upgrades, and more. Besides, it would help to consider the following factors before deciding which type to buy.

  • Port Density: Depending on the number of ports needed, POE switches have different port densities (number of ports per switch). The more ports you have, the more devices you can power with one switch. 
  • Power Budget: Since different switches offer different maximum port powers, you need to consider how much power each device requires and how many devices you need to power. This will help you determine the total power budget for your system.
  • POE Compatibility: Ensure your devices are compatible with the POE switch. Otherwise, you won't be able to power them.

POE type 1 is suitable for basic network installations with low-power-consuming appliances. POE+ is great for medium-sized networks that need more power, while POE++ switches best meet the high-power requirements of large digital projects. Ultimately, your network requirements and the powered devices determine the most suitable switch. 

Now that you understand the differences between POE vs. POE+ vs. POE++, you will better understand which switch will better meet your needs.
