Description
What Is a PoE Splitter
PoE splitters are the devices that are used together with PoE switches and PoE injectors.
Instead of taking both data input and power input and turning them into a singular output, they supply power by splitting the power from the data and feeding it to a separate input that a non-PoE compliant device can use.
PoE Splitter FAQ
PoE splitter vs injector: What’s the difference?
Both PoE splitter and PoE injector are frequently used power devices, however, they go in the opposite direction.
A PoE injector, also commonly known as midspan, adds power to data that is coming from a non-PoE switch or “endspan”.
It supplies power through the network cable to PoE equipment such as wireless AP.
A PoE splitter also supplies power to the device however the main difference is that it splits the power from the data to a separate input that the device can use.
PoE Splitter Buying Guide
First and foremost, you should make sure the PoE splitter you want to buy can co-work well with the powered devices in your network.
Generally, the PoE splitters on the market conform to IEEE 802.3af/802.3at standards. PoE splitters can be powered by an 802.3af PoE input if the total output is less than 15.4W, or they can be powered by an 802.3at input if the total output required is less than 30W.
The input voltage of powered devices should match these specifications and not exceed the output of the PoE splitter.
What’s more, make sure the PoE standard compatibility of PoE splitter with other 802.3af/at PoE-compliant network switch or injector.
