The Benefits of Using PoE

Power over Ethernet (PoE) has been around for awhile now. Chances are you use PoE at work and maybe even at home. PoE has several benefits that we will expound upon in this week’s blog post.

 

PoE provides data and power over a single Ethernet cable which is a pretty brilliant idea. PoE first came to market in 2003 and has flourished since. With its first release 802.3af, PoE was able to provide 15.4 watts of DC power to a connected device such as a PoE enabled IP phone or Wi-Fi access point. The most current implementation of PoE, 802.3at can send a whopping 25.5 Watts of DC power to an end device and can be used with PoE enabled pan, tilt and zoom (PTZ ) IP cameras for surveillance applications.

 

Currently the Institute of Electrical and Electronics Engineers (IEEE) is working on the next generation of PoE called 802.3bt. 802.3bt promises up to at least double or even triple the power output of 802.3at!

 

Possible future applications for 802.3bt include point of sale (POS) credit card readers, building lighting and access controllers, industrial brushless and stepper motor drives, video conferencing systems and more!

 

Well here it is… a breakdown of some of the major benefits of PoE

 

·         Fast deployment of devices and services

·         Flexibility of device placement (no AC wall outlet needed!)

·         Cost savings as new AC outlets do not need to be installed

·         Cleaner installations, no unruly power cables required

 

Here are some typical applications and uses for PoE Splitters and Injectors
