PoE, PoE+ and Poe++: Choosing the Right Industrial Ethernet Switch for You

For over 15 years, Antaira has been providing rugged industrial Power over Ethernet (PoE) switches. In any application, these PoE switches can provide rugged and reliable connections that ensure critical uptime. These industrial PoE switches meet industry standards and come in several product options, which allows for compatibility with your unique needs and applications. In an unmanaged situation, a plug-and-play industrial PoE switch will fit the bill. In an application where the demands are more hands-on for network managers, managed PoE switches provide the solution.


There are two types of PoE devices. One in which the device transmits power, called Power Sourcing Equipment (PSE). The other is where the device must draw power, or Powered Device (PD). A typical application for PSEs is industrial networking switches. PDs appear commonly in VoIP phones, wireless access points, and IP cameras.

PoE vs. PoE+ vs. PoE++

In beginning your search for an industrial PoE switch, you’ll find three common types – PoE, PoE+ and PoE++. Antaira offers PoE switches that meet all industry (IEEE) standards: 802.3af (PoE), 802.3at (PoE+), and 802.3bt (PoE++).


Traditional PoE switches are designed to power low-power devices, such as IP telephones. This means that there can be some loss of power, and these ports are typically rated at 15.4W and up to 44-57V.


PoE+ switches are backwards compatible with PoE switches, which delivers more power. The transition from 802.3af to 802.3at is relatively simple. A PSE designer will have to spend more time engineering the change to 802.3bt, but Antaira offers compatible industrial switches. A PoE+ port bumps up its rating to 30W and 50-57V to power higher-end devices.


Finally, PoE++ solutions, broken down into Type 3 and Type 4 solutions, take those specs even further to deliver, in Type 4 scenarios, 100W and 52-57V capabilities.


It’s important to note that a switch can be advertised as PoE++ even if not all ports are PoE++ enabled.


In summary, it’s critical to work with a trusted partner to determine which switch best suits your needs and the demands of your environment. PoE, PoE+ and PoE++ differ in max port power, port voltage range, twisted pairs used, max power delivered to the device, and voltage range to the device.

PoE Switches for Mission-Critical Applications

In both adverse environmental and weather conditions, Antaira offers several Industrial PoE Switches. PoE Switches use RJ-45 Copper Port Technology to leverage strong connections over long distances and increased speeds. With connection capabilities of up to 100 meters, and speeds of 10mbps, 100mbps and 1,000mbps, there is a reliable option for any industrial application.


Using a single-twisted pair Ethernet cable, PoE provides data and utility transmission just like any other port, but they also provide electricity through the same cable.


The Benefits of Industrial PoE Switches
  • Strong connections over long distances with increased speeds.
  • Fiber connectivity options for PoE switches.
  • Options for 802.3af,, and 802.3bt.
  • Option to use a single twisted pair Ethernet cable.
  • Multiple managed port options ranging from five to 28, depending on the voltage.
  • Unmanaged port options ranging from five to 26, depending on the voltage.
Industry Solutions for PoE Industrial Switches

Antaira’s Industrial PoE switches work in a variety of settings.

  • Machine vision, where significant bandwidth and connectivity are required between systems.
  • Surveillance with constant network monitoring and minimal downtime.
  • Law enforcement situations that require a broad environmental and temperature operation capacity.
