Ethernet Surge Protector (2 Pack) Gigabit High PoE++ Class 8 (154W/3.2A) TP302x2

I can't speak directly to the lighning protection as I'm not sure how I'd know, but I can say this is well built AND isn't just gigabit. Between my 2.5g capable switch and PC I'm getting full speed per iperf tests. Very excited that I'm not giving up those speeds, though I'm not sure if it will reduce maximum cable runs or whatnot.

Bought this to protect my router from all the lighting in my area, I've lost one router already. This is protecting the CAT5 STP that comes in from the outside Wavelink AC1200 AP. The Wavelink is also grounded directly so I'm really hoping that there's no more Lighting issues. If there's any changes I'll update this review.

Used for both a weather station and a PoE microwave dish. Although in an enclosure, I had an issue with water intrusion. Caught it, removed the minor corrosion caused by the CAT 6 cable, sealed it up with dielectric grease and it is back in service. Works fine for the installation. Keep in mind that this in not meant to be installed outdoors unless it is in a protective enclosure.

The construction is good. I grounded these using the green/yellow ground wire on a ground bar; it looks like it is also possible to screw them to a grounded surface. Of course, the only way to know if these really work is by destroying them in a lightning strike (or by using expensive test equipment). I didn't do that! I also did not open them up to see what's inside. I was asked to rate their quality "for traveling". I am not sure why. In any event they are not good for traveling since they require screw installation of the ground. They will be ineffective if used without grounding.

For what it is, it's pretty good. I like the metal case, the ground wire. Decent build quality inside. The description is not very detailed - but it does mention the gas tubes. (update: The description now includes _much_ more information!) It does not mention there are no diodes. But it is quite a bit less money than a L-Com with diodes and gas tubes, so if you feel your situation doesn't warrant the additional money for the two-layer protection - then this could be just what you need.

Very easy to install and connect. Did not slow our speeds down at all. Saved us for a third very costly replacement due to lightning strike. Very convenient size. We have several networks and I have put one on every line coming to save us money in the future. Great value I’d say. Already saved me money!

I wanted to write this review after a real-time incident. I bought these several months ago after I had my whole computer network fried by a surge. I have my buildings connected with shielded direct-burial CAT6 cables. We had a recent close thunderstorm that apparently was close enough to generate a surge in one of the buried cables. The TUPAVCO TP302 PoE+ Gigabit surge device was destroyed, but all of my expensive equipment is fine. So I highly recommend these to protect your network if you have anything that is likely to experience a surge. Note that they must be directly wired to your neutral/bond wire in your building wiring system so that the surge can be shunted to the building ground rods.

After a recent surge over our ethernet network from a nearby lightning strike, I decided to add these to the incoming lines from all the outdoor cameras. The cameras are POE and the protector allows them to work properly after being installed. I haven't seen any issues with the cameras going offline or degrading their throughput. I also tested these on a 500 mbps ethernet connection to my PC and an internet speed test showed that with the protector installed my device was still able to achieve the full speed provided by my ISP. I hope they function well if we encounter another nearby lightning surge in the future. We lost a lot of connected equipment prior to installing these. When installing, I made sure these all had a direct connection to our outside ground rod where the incoming cable TV line is also grounded to help dissipate any future surges.
