Ethernet Gigabit Surge Protector Kit with CAT 6a Jumper Cable and Ground Wire (Supports POE++, POE+, POE, Non-POE)

These protect my ethernet lines without affecting gigabit speed.They are easy to install. The grounding strap hooks over a standard plug, which is especially convenient. The inclusion of a short ethernet cable is much appreciated.Of course, the bottom line is do these work to protect ethernet against lightning strikes and other surges. I don't know, and perhaps I will be fortunate enough to never find out!

I can't vouch for its surge protection, but it works without causing issues. It works for 2.5Gbps too

Was impressed with the build quality. Item is a small aluminum enclosure. Didn't take it apart, but based on box and ground wire, appears to be a well built device. Bought it to provide network protection after the UPS network surge protector gave up its life protecting the rest of the network. That surge also fried the cable modem.

Easy to install, no speed loss on my 1GB service.

Fast delivery and easy install

This is a great little piece of equipment that will help protect your Lan From Lightning...

It was recommended by Xfinity tech to isolate modem from router, but it did not work. Internet still drops out 2-3 times per day. He said it was static charge?

Used this to protect a direct burial, shielded CAT6 ran 200 feet to a outdoor access point. there is some confusion about which way, or which is the in or out for the ethernet cable and what side does the stuff go to be protected. I guessed that the 'IN" would be ethernet going outdoors? Got a reply from vendor, but it did not answer my question. I grounded mine with a outdoor ground rod, using some additional 16 gauge copper wire to run it outdoors. I was hesitant about using my house's ground system, since my neuteals and grounds are bonded together in house panel. I do not have seperate ground wire to the meter. i am out of NEC as of 2006 standards. Using speedtest, the speed is same as cable indoors next to router.
