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

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.

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!

Arrived on time and was basically plug and play. I installed it in a UniFi UDM, and it was recognized immediately with no negotiation issues, no link flapping, and no manual tweaking required.It joined my 10GbE backbone cleanly and has been stable since day one. For a copper SFP+ transceiver, that’s really what matters: clean link establishment, compatibility, and reliable throughput without adding complexity to the network.

This transceiver has helped us out many times to hookup a 10G capable switch to a 10G backbone while the switch has only SPF and SPF+ (the one you need) ports. While you could opt for a Coaxial or Fiber SPF+ to SPF+ direct cable in certain cases, where you need to connect to 10GBase-T ports this thing is great and fits DLink and TP-Link switches just like Cisco's.

I have purchased many of these in the past and they are all still in production. Good value.Using them in EnGenius switching.
