Premiertek PT-POE-GSPK GIGABIT PASSIVE POE INJECTOR AND SPLITTER KIT 9/48V White

I am by no means an expert on this but from what I can tell these are quite rare. Not a lot of companies make passive poe adapters that are both passive AND 1Gbit.We have a fiber to ether box provided by our ISP on the roof of our home. They used a 100mbit passive adapter. It was starting to fail so I had to replace it, decided to see if I can find a passive 1gbit one. I did.After replacing the old one with this, the ethernet port auto negotiates to 1gbit. My internet speed jumped from about 95mbit to about 270mbit.There is about 3 floors between my home router downstairs and the fiber to ether box on the roof. And I am powering it via a good quality 12V (5A, shared with my router and switch though) adapter. 12 hours so far, no issues to report!

I decided to use this to bring battery power from my backup battery upstairs to my WiFi. Around a 35-foot run with minimal voltage drop (<0.2v) despite multiple cable extensions+changes in cable gauge.It didn't work directly with my WiFi since the voltage regulators inside my access point can't handle the voltage changes when the battery dips below 12.2V, but a Netgear 16-port switch holds up a lot better.If I used a boost-buck converter I think this would work perfectly with my WiFi 24/7.Update: November 4, 2022 -> Febuary 22, 2024. This is still working. I used a voltmeter to adjust my boost-buck converter so that the voltage would account for the drop across the ethernet cable. It works perfectly. I drained my LiFePO4 12v battery all the way down to 11.0V before my solar controller decided to cut the voltage output. That's when I realized I was using PoE and forgot to finish the battery system maintenance.Probably going to buy another one of these soon. I have another project that needs better PoE and this is about the best injector+splitter kit I've seen on Amazon so far, and I've been looking.

After some trouble with various other PoE setups, I decided to give this a try to power my Orbi using an ethernet cable. To my surprise, this works great. I plugged my included power adapter into one end and used the included splitter on the end end. Worked flawlessly - great for setups where there aren't outlets available or are practical.

This might have been a defective unit but this part blew up the ethernet port on the (non-POE) wifi access point on the splitter side. I am guessing power leaked through the splitter (definitely not a good thing!!!!) and killed the port which will now only auto negotiate at 100 Mbits. Pretty annoyed by this. Amazon will refund the premiertek kit but I am out a wifi access point which is another $160 down the drain. So buyer beware!

Working perfectly as described and shows that it is passing gigabit speeds through it. I don't have a way to verify this other than the devices connecting through it are getting a gigabit connection.My network rack is downstairs and my wireless router is upstairs in the optimal position for complete wireless coverage at my house. The rack is on a battery backup so I wanted to keep the router up when the rest of the equipment was on backup. This runs from the port on the cable modem, through the patch panel, through 30 ft of cat5E, through a punchdown keystone and 3ft out to the router.I'm using the original Netgear power supply and there has never been a glitch. Some suggest that a larger power supply may be required for these runs but I had no problem. Either the power supply was oversized to begin with or there is minimal loss through the line.

I tried to use it to power a router remotely but the bandwidth was reduced. I had to run a power extension separate from the cat vi cable. This reduces the bandwidth because it uses some of the wires for power.

This was the perfect solution for powering my Deco M5 main access point, and it was very affordable! My servers, cable modem, and router are all in the basement and connected to a UPS (battery backup). My main Wi-Fi access point, however, is in the living room on another floor, hardwired via Ethernet to the basement. I wanted to have a battery backup for the access point but didn't want to splurge on a bulky UPS just for that. This POE kit was the perfect solution.I moved the Deco power adapter into the basement, and using this kit, I'm now powering the Deco in the living room over Ethernet and it's therefore connected to the UPS in the basement. It's absolutely splendid so far. Let's see how long this lasts. I'll update this if there are any changes.
