10Gtek for Cisco SFP-10G-T-S Compatible 10GBase-T SFP+ 10 Gigabit RJ45 Copper Transceiver 30-Meter

SFP+ to RJ45 copper transceivers run hot to the touch because they draw significantly more power than fiber optic modules, often over 3W, to process high-speed 10G Ethernet signals. The small metal case of the transceiver traps heat without an easy way to dissipate it, so these modules can reach temperatures up to 70°C (158°F) and feel very hot during normal operation. Fiber or DAC modules run much cooler by comparison. My 10G Setup: I. Dell Optiplex 7060 SFF i7 8700 (256GB NVMe M.2) running OPNsense A.

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.

Have been running these for a while at 2.5G and 10G speeds on a Ruckus switch. They run cooler than other 10G-T devices I have used from other brands. Overall they have worked well, and are a great value for the price. I did have a problem with them randomly dropping packets on connection. I contacted the manufacturer and they had no problem replacing them for me! I did some troubleshooting, and they approved the RMA. The process took less than a week to get replacements so I would certainly buy again.

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. But I had the opportunity to add a fan, so I did. 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.
