The difference between an injector and a splitter is that a PoE injector sends power to PoE equipment that receives data through existing non-POE switches. A splitter also supplies power, but it does so by splitting the power from the data and feeding it to a separate input that a non-PoE compliant device can use
Power over Ethernet, even if your device does not support it.
The Power Over Ethernet Splitter enables you to supply your network devices, such as access points, LAN cameras or switches / hubs that are not PoE-capable, with power via the CAT5 / CAT6 cable regardless of where you need the devices existing power sockets.
What Is a PoE Injector?
A PoE injector, also called midspan or PoE adapter, can be implemented to make a non-PoE compatible switch work with PoE devices by powering compliant devices over a single Ethernet cable, which is perfect for low-power devices that need to be set up in locations where a power outlet is unavailable. It thus enables more flexibility by offering access to install devices in hard-to-reach areas, with a minimal impact on existing structures and budgets.
Here are some distinct benefits of PoE injectors:
- Ease of installation: simply connect the PoE injector to the PoE endpoint and to an Ethernet switch to provide data and power.
- Flexible to network expansion: PoE injectors add PoE capability to non-PoE Ethernet switches, which extends the network connection distance and provides combined power and data over Ethernet cable to end devices for a better connection.
- Minimal investment budget: Utilizing the existing Ethernet equipment and cabling infrastructure, the relevant costs will be minimized in a PoE injector solution.
How Does a PoE Injector Work?
When Ethernet switches or other devices have no PoE function but need to support PDs (Powered Devices) like PoE IP cameras, PoE wireless access points (WAP), PoE lighting, etc., a PoE injector can help transfer both power and data to these PDs up to 100 meters. Usually, a PoE injector converts the alternating current into the direct current so it can be the power supplier for low voltage PoE devices.
