Poe Texas PoE Injector - Single Port Power Over Ethernet Passive PoE Adapter - 10/100/1000 Gigabit Data Accepts 12v to 56v DC - Plug & Play Home Office VoIP Phone WiFi AP - Power Supply Not Included

I've used this POE device in conjunction with a GPOE-1AB splitter to deliver 28 VDC to a remote Ethernet device. It appears to have no effect on the 300 MBPS Ethernet data (We do not have 1 GPS service yet). You should be aware before purchasing that this device only does Power Over Ethernet on pairs 4 & 5 and 7 & 8, and this cannot be changed. Use a different device to use the other pairs. Customer service by this company is also excellent.

I use these injectors in my battery box builds. I like them because I can pair them with different voltage step-ups in my 12v systems and get the power I need to run the desired equipment. Most recently I put in my solar build to run a security camera.

Couldn't get it to work. Tried several 12V power supplies and different Ethernet cables. It couldn't power up my POE router. The LED turns on but it doesn't work. The router works fine with a different POE.

Was very late getting it. The product works.

(Power Supply NOT Included) Feed power up to 48 volts DC with ease. Power is not required to pass data. These small devices that do the trick. The internal schematic sealed the deal, you see how simple the design is. These are much more flexible and lower cost than passive pigtail adapters. Note: These devices are polarity specific, positive and negative. If you have polarity flipped, no power will pass through.

Fits the need for a compact single port Mode B PoE injector. We have used these previously as injectors and splitters where the space would not allow installing AC power for the power supply

Yes this is gigabit speed not just 100 poe standard. User supplies the DC power to the unit via a 2.1mm connection. Works with TP Link CPE710 GBE 24V.

I purchased dozens of these during the past several years and did not notice a power supply is not included. But on the bright side, this will power any PoE device, even those not requiring 48 volts. Try plugging in a 24 volt supply into other POE injectors and in most cases, they will not power-up. This one does. As for the rating...What on Earth is sheerness? I purchased a PoE adapter, not a pair of panty hose.
