10GBASE-SR SFP+ TransceiversI can't believe how cheap these are. I've tested all 10 and they work like a champ. I'm glad I found them when I did. I'm working on running CAT6 through the house and now I'm going to run fiber alongside.If you have a bunch of switches with empty SFP+ ports then you really should check these out. At $18 for both ends of a 10Gbs connection it's too cheap NOT to do it. It's so much cheaper and simpler than messing with 10G over copper. Look up how cheap OM3 LC to LC cables are.I just hope they get more in stock since I grabbed the last of the 2-packs.

Appear to be of good quality. I have tested two, and will have all 4 deployed when the second switch arrives tomorrow. They were the best deal for copper SFPs that I was able to find.

Excelente y compatible

Works for both for the link between the Quanta LB6M(Running TurboIron Brocade firmware) & the Cisco WS-C2960L-24PQ-LL(latest firmware) as well as the link to my PC (Intel X550-T2[Dual NBase-T])

Pros:These worked in my Unifi Pro switches, at full speed and with the serial numbers visible to the system. Good price.Cons:Manufacturing of these is off by a few microns. For starters, when you plug in a cable with an RJ-45 plug, the tab does not lock the cable in the port properly because it doesn't fit very well. In order to get it to lock, you have to scrape off, maybe 1/2 mm of plastic from the tab on the RJ-45 plug. I tried this with multiple brands of cables, so it's definitely this jack and not the plug on the cables.Also, when I went to remove one of the two I had installed, it did not want to release from the SFP port. The gold frame that you use to pull-and-release was not completely disengaging it from the lock, again by just a few microns. After much wrangling, I finally got it out, but not until after the release became bent out of shape somewhat.While these aren't huge issues, I'll still use a different manufacturer next time. Some people might not ever need to remove cables from the port, and transceivers from the switch, I do sometimes.

The QSFPTEK 10GBASE-T SFP+ to RJ45 Copper Module Mini-GBIC Transceiver for Cisco SFP-10G-T-S is working very well in a Sodola 10G managed switch, albeit the temp does not display in the Sodola switch's internal management software. A couple of Sodola gbics actually do report their operating temp within the management software, so, be aware of maybe not having all relevant information or data available when used on non-Cisco switches. The Sodola gbics' temp display at 138 *F. Ensure you have plenty of air movement around the switch when using these. Otherwise, these are comparable to the switch's brand-name gbics. They may even work better than the Sodola gbics if used in a Cisco switch.

Much better price and full speed, no complaints from Ubiquiti Moved the LAN wire from the gigabit port WAN to WAN2 fiber port with this adapter works flawlessly and shows 10G on the Ubiquiti GUI Screen, solid connection.

At first I bought another SFP transceiver that includes the cable from one to the other and I bought the wrong one. I can confirm that this one works for the WS-C2960S-48LPS-L Cisco switch. I wanted this to connect my Ubiquiti UDM Pro to that switch for my home lab AND to practice with the CLI in order to get my CCNA later in the year. So this works for that. Confirmed.
