-powers 802.3af/802.3at devices "passively
This device is a very cost effective injector at gigabit rates. When used as an injector it inserts the DC voltage at the source location. The DC voltage is then carried over the active data pairs in the network cable. The same device can be used as a passive splitter to extract two voltages from the ethernet cable while operating at gigabit speeds

Use with IP security cameras, phones, wireless access points and other devices that accept passive 802.3af or PoE+
1) What is "PoE".
PoE is "Power over Ethernet." A device like this one takes DC power and injects on one or both pairs of wire in the Ethernet cable. It's used to power IP cameras, VOIP phones, WiFi Access Points and other network devices
2) How long can the Ethernet cables run from the injector for a PoE phone, for example, to function reliably?
The cable can run for 328 feet or 100 meters.
3) What's the difference between active and passive PoE?
Active means the Power Supplying Equipment (PSE) sends a short low voltage signal to your Power Device (PD) as soon as it is connected to determine how much power it needs, then this PSE sends only that power. The most common case for this is when you have a PoE port someone could plug a laptop into by accident. The laptop isn't PoE and could be damaged by it, so, if you have an active PSE, it won't send any power to the laptop accidentally connected to it. Passive sends PoE power all the time, which works great for most PoE specific applications like cameras, WiFi access points, or a port you know only PoE devices are attached to. Both work great for the right application.
4) What does it mean when a PoE device is "passive"?
Passive means that the power is on all the time. An 802.3af switch keeps the power off until a compatible device is attached. A passive PoE injector or switch provides the voltage (usually 48 volts) all the time, so you should only plug in PoE capable devices.
5) What is the difference between Mode A and Mode B?
Mode A and Mode B are two different PoE pinouts (the wire pairs used to transmit power). Mode matters most if you're powering a 24 volt passive PoE device like those from Mikrotik or Ubiquiti. These devices always need Mode B. If you're powering a device that has a spec of "802.3af" (48 volts), then either mode A or B should work.
