10Gtek 𝟭𝟬𝗚𝗕𝗮𝘀𝗲-𝗧 𝗦𝗙𝗣+ 𝘁𝗼 𝗥𝗝-𝟰𝟱 𝗧𝗿𝗮𝗻𝘀𝗰𝗲𝗶𝘃𝗲𝗿, 10Gbe SFP+ Copper Ethernet CAT6a Module, up to 30m, for Cisco SFP-10G-T-S, Ubiquiti UniFi, Fortinet, TP-Link and More

Works in my UDM Pro Max and getting a full 10Gbe connection to my fiber ONT. While set to 10Gb on the SFP+ port, it still connected to a 1Gbe Ethernet on my old ONT just fine. It does run a bit hot like it says on the package. Heat is typical for these adapters. I added heat sinks like another reviewer and dropped running temps a few deg C. Install was simple, just plugged it in and plugged in an Ethernet cable.

So I just upgraded my internet to 2Gig up/down but my internal home network was stuck at 1G uplink to the router that also had a 2 10G ports. I have a cisco switch as my main switch aggregate to the router but didn't have anything to take that next step to getting higher speeds between the switch and router. I got my hands on a cisco 10g module for my switch and then bought this 10G copper sfp to get me there. This SFP didn't even cause the cisco switch to throw an error that it wasn't a supported transceiver. It worked perfectly and now you can see the beautiful throughput I'm getting now from my PC. Highly recommend if you're upgrading and you have SFP+ ports to work with.

Put this in our Unifi UDM Pro to connect to a 10G service. Works well with zero issues.

It says it works with Unifi, but it doesn't push the through put as stated on the UNIFI UDM Pro. The Unifi UDM Pro shows it a 10gig link. Know for facts the fiber hand router is pushing 8gigs each way. Never have had issues with 10gtek products. I think it would work fine just not in the UNIFI port 10 for 8gig throughput.

Update: 10GTek reached out to me and offered a refund if I returned the adapter. The thing that I most appreciate, however, is they asked for a lot of information about my system and how it failed. They want to test the returned unit to see why it was acting this way. I can't ask more of a company than to stand behind their products and try to better them as they find issues. I would be very comfortable buying more products from them knowing now that they will stand behind their products past the 30 day return window.This worked great for about 45 days as the WAN adapter on my Ubiquiti UDM, then all of a sudden I started having all kinds of speed problems, latency, and dropped packets. It correctly negotiated the port speed on the ethernet side (5Gb) and never ran hot. I thought it was an ISP issue but when I removed this adapter and went straight into the 1Gb ethernet WAN all of my problems went away. This is absolute junk and now the return window is closed.

10GTek is quickly becoming one of my favorite brands! I have a few network cards and SFP cables. This carries just as much quality as other big name brands. It comes packaged very nicely. Sturdy build and feels quality!. Plugged right into my UDMP and it auto negotiated to 10G.

works well, no performance issues. Good price. Used with Unifi switches and other gear.

Works well, although like another reviewer mentioned it won't work/negotiate at a lower 100mb speed. Using it in a trendnet 2.5gb switch.
