Cisco 10GBase-T SFP+. Product does not work with Cisco 3850-24XS-S, never established a link. Buyer beware this is the same company as 10Gtek.

Works as expected in my Cisco C2900XL switch

I bought this under a work account, so I will not show as a verified buyer. Issues: Devices below are on package version 6.47.9, firmware version 6.47.9 Model CRS226-24G-2S+, no link, never worked. Mikrotik OEM S+RJ10 does work Model CRS326-24G-2S+, same as CRS226 Model CRS328-24P-4S+, had two connected together, 15 meter connection, port was flapping anywhere from 5 times a second, to once an hour. Gets much hotter than the Mikrotik OEM S+RJ10. Mikrotik branded 60C, Ipolex was 65C surface temp, temp was not registering on devices. I had high hopes for this device, but I would not suggest it. Id suggest spending a little extra and sticking with the Mikrotik OEM S+RJ10.

Great price for a 10G SFP+ RJ45. Works just fine in a Zyxel XGS1250-12 switch. I have my Mac Studio plugged into it and Im getting a rock steady10 Gbps link.

Plug and play. We use these with Cisco SG300-10P and SG350-10P switches. Have not had any problems with them.

Worked great for me! 10GBe on an old server card I got off eBay

It was delivered fast and reasonably priced. I bought a couple of these to install on my Ubiquiti Dream Machine Pro SFP ports. I hooked one up to my UDM PROs SFP WAN2 port and connected to my ATT BGW320-505 RG 5GB port using a Cat 6 patch cable. I had to tell my UDM Pro to configure in the WAN2 port at 10 GB speed as it was not initially configured out of the box. Unfortunately the UDM Pro does not currently support load balancing so I have to disable the 1GB Lan port to test it. It does do failover so I can literally pull the WAN1 patch cable and It works. However the Work in Progress is that the upload speed appears a bit slower than it did on the 1GB Lan port. I dont know if thats just the speedtest vagaries or if its a UDM problem with WAN2. I have read a few other people havingsimilar problems. So its still a WIP. Also, I do not yet have a desktop with > 1GB lan port so I cant test any over provisioning yet if I have any from ATT. Either way the Transceiver worked out of the box on my UDM Pro.

Im using these SFP plugs to go from my basement (networking room) to my study on my 1Gb system and they work well.

Worked out of box with my ASUS router and my Netgear 10g ethernet switch. Highly recommend it for your rack!

Works as expected for my Netgear GC110P and also my CISCO SG-102-24-NA. I have also recently installed it in a netgear GS324T S350 series.
