10Gtek for Cisco Compatible GLC-T/SFP-GE-T Gigabit RJ45 Copper SFP Transceiver Module, 1000Base-T

Wotks like charm in my Cisco 3750-x 12 port fiber switch. And also in Cisco 2960-x....recommended to every network person....go for it guys.thumbs up

Fonctionne est à régler mes problèmes de flapping sur UniFi.

When the 10Gtek arrived in the usual new "green" shipping package, I felt the "box" it wasn't the usual and I had to get this thing open and see what it is. The container it comes in is genius. It took the great deal I got and hope that it works to "Holy Crap this is So Cool!" and no doubts about it's operation. Upon opening the little metal box by sliding the top, there was the dongle. I had a bit of a problem taking it out of the plastic holder. But once out if it weren't for the way the device was presented I wouldn't have been as impressed. There's nothing initially special about any of these things, so it's not the only one that's "non-descript". Although it's a great value it doesn't seem cheap. I started to look for any specific instructions that if there were any special directions that needed to be considered. I took out the plastic holder insert the dongle came in and no little folded piece of paper with type so small you need a microscope to read it. But then noticed the instructions were painted on the under side of the lid which are simple, very readable and easy to understand. It fits like a glove when I plugged it in and is completely compatible with my UniFi UDM Pro and works without needing anything special. Pop it in and that's it. The system is showing it as if it were OEM. Make sure you use a minimum of a Cat6a cable, it does matter. The Heat Level, I haven't noticed anything more than warm. Speed wise, right now I only have a 1Gbps connection but I'm getting over the spec'd 940 Download/940 Upload speeds. This coming Saturday I'm having 10Gbps installed and I trust that I'll get darn near their spec'd maximum speeds. Can't wait.

I inherited a Netgate XG7100 router/firewall and it has very particular requirements for transceivers. Specifically, that it doesn't support SFP+ to RJ45 devices. This device seems to work perfectly and came up immediately after install. I have been performing load testing and have seen no issues due to overheating or packet loss. EDIT: Since I originally wrote this, I have had one issue where I had to disable and re-enable the interface to bring up the connection. Not sure if the issue was this device or the ISP's ONT it is connected to. No errors were logged leading up to the issue or after the reset. As this listing on Amazon has multiple variants, it is important to note that I am referring to the "10Gtek 𝟴𝟬-𝗠𝗲𝘁𝗲𝗿 𝗟𝗢𝗪 𝗣𝗢𝗪𝗘𝗥 10GBase-T SFP+ to RJ-45 Transceiver". This is the only variant confirmed compatible with the XG7100 due to the specific chipset used in the device. The other devices use a different chipset and are most likely not compatible. This was the most cost effective and simple solution that I found to add 10gb copper to the XG7100. My other options were to get a media converter to take the handoff from the ISP, convert it back to fiber and then connect it to the router. This would have required the purchase of a media converter, two to three transceivers (depending on converter model) and a fiber cable and would be more equipment to mount on the wall. It would also require additional power. The other option would be to purchase a PCIE network adapter, which the XG7100 is also picky about. New models cost about $150, used can go for $35-$100, but it can be guessing game on whether they are reliable and will work. There still be the need to get an SFP+ to RJ45 transceiver. I found this listing referenced in the NetGate forums thread "xg7100-confirmation-if-you-can-plug-in-an-sfp-sfp-to-rj45-adapter"

Works great for my Unifi Setup with my Cloud Gateway Fiber for full 10 gig network connectivity! This made sense and I am not regretting buying two of these Transceivers at all. It's a good price to performance ratio and it does as advertised properly. The only gripe I have with the SFP+ Modules is they get REAL HOT (99 Celsius) Make sure you have decent cooling where you are installing the modules as it'll save them from burning up and frying. I love the speeds and reliability they give and I highly recommend this to anyone who wants 10 gig connectivity over RJ45 Ethernet Cables!
