More Power to You! The New Standard for Power-over-Ethernet Has Been Ratified

The new IEEE 802.3bt standard for Power-over-Ethernet was ratified on September 27, 2018 and with it comes new demands for power. PoE standards regulate the delivery of power to end devices, and the IEEE 802.3bt standard is necessary for devices requiring higher levels of power such as PTZ security cameras, IP phones, wireless access points and more. The new standard is backward compatible with IEEE 802.3af (15.4W PoE) and IEEE 802.3at (30W PoE+) and provides for the delivery of increased PoE power from 60 Watts to 90 Watts (PoE++).

Power-over-Ethernet technology has been around since 2003, but the demands for the technology are growing exponentially as new, diversified applications are expanding. The new applications, such as PoE-powered LED lighting, intelligent buildings and IoT for instance, coupled with the growing number and capabilities of the end devices, are demanding greater amounts of power and bandwidth.  These sophisticated devices can be connected and powered over a single cable thanks to this new PoE standard, which simplifies installations and reduces costs.

While considering your PoE needs and the various product solutions available, it is important to select vendors that provide equipment designed to be compliant with the new 802.3bt standard. Some of our recently released products include our 24 Port Managed Gigabit Ethernet PoE++ Switch which is ideal for intelligent lighting applications and our 8 Port Managed Hardened Gigabit Ethernet PoE++ Switch that is designed for ITS applications.

4-Port PoE++ Switch DiagramAnother revolutionary PoE++ product that will be available later this year is our 4+1 Port Self-Enclosed Managed Hardened Gigabit Ethernet PoE++ Switch. This one-of-a-kind switch integrates all the required components in its own IP66 rated enclosure for simple mounting in outdoor environments. The switch also incorporates a variety of features like Near Field Communication (NFC) for simple configuration of the switch prior to powering or connecting it, and Bluetooth Low Energy (BLE) for remote access to monitoring, troubleshooting and making changes to the switch without retrieving a scissor lift for physical access.

Now that the standard has been ratified, we expect it will spur growth in new applications like LED lighting, intelligent buildings and Intelligent Transportation Systems. Along with this increase in PoE power level, it’s time to think about other ways to take your network to the next level. We’re here to help your networks evolve, so please feel free to contact one of our network experts with any question you have.


I’ve used Transition Networks’ products in my customer installations for years. I’ve always found their products, customer service, sales, and tech support to be top-notch. I wouldn’t even consider using another brand.
