1.25/2.5/5/10G-T SFP+ to RJ45 CAT.6a Copper Transceiver, Auto-Negotiation SFP+ Ethernet Module, up to 30-Meter, for Cisco SFP-10G-T-S, Ubiquiti UniFi UF-RJ45-10G, Netgear AXM765 and More

Product works perfectly. Used it to connect from Cisco Catalyst 4500X to iSCSI SAN. I also received this T-Shirt from 10GTek after contacting their customer support with some questions that they happily and timely answered.

Product was as advertised and arrived quickly. Was installed in a Cisco 4500 switch and worked as expected.

Fit perfect into my 10g slot and my cat6 cable slid right in

Not sure if other people tested these SFPs carefully but the RX and TX do not run at 1gig duplex speeds. I connected this to my WAN with a Cat8 cable to my router and although my download was hitting 930 my upload was hitting 30 out of 980. These are not suitable for ubiquity equipment even though it claims to work. I will probably just throw it in the trash and purchase one straight from ubiquity.

Purchase several fiber components from 10Gtek, this copper 10GBase-T transceiver arrived promptly and was truly plug and play. There were no issues with the connectivity to the Mellanox switch it went into. Temperature is running as expected. Will continue to purchase components from 10Gtek.

I have Adtran switches with 10g sfp+ uplink ports. I was able to manually set the speed to 10gbps and these transceivers work great.

The release clip is a bit fragile, but the product works as expected, and if you dont have to move it often, wouldnt have any issues.

Does not work in cisco 9500, even with 3rd party modules enable command. Does work in cisco 2960XR

Product shipped quickly and was as-described. I will be ordering again.

Someone gave me a 10Gtek 10Gb network card with a single SFP+ port. So I got this Transceiver because it was the same brand. The card was installed in an old Windows 7 sever. This transceiver allowed me to connect the PC to a 10Gb Netgear switch. Happy with the purchase as everything worked fine at the first try
