10Gtek 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-X, Netgear and More

I need a transducer to be able to connect the Mac mini using a Plugable 5G ethernet adapter to properly hook it up to my 10G aggregation switch. The price is good. No errors on my Unifi based Network hardware. Up until now no heat issues. practically Plug and Play, and now my mini can interchange data at speeds not know to it. The aspect of this transducer being mutispeed permits me to connect any pc at the speeds it can negotiate: 1.25, 2.5, 5 ( my Mac mini speed ) and 10G. Very nice addition to my setup. good quality. And very easy to install. As You can see in the picture, the bottom row second from the right is the 10Gtek transducer.......

Have been running these for a while at 2.5G and 10G speeds on a Ruckus switch. They run cooler than other 10G-T devices I have used from other brands. Overall they have worked well, and are a great value for the price. I did have a problem with them randomly dropping packets on connection. I contacted the manufacturer and they had no problem replacing them for me! I did some troubleshooting, and they approved the RMA. The process took less than a week to get replacements so I would certainly buy again.

Works as planned, connects my ONU to the SFP+ port on my firewall.

Works well in both Cisco and Mikrotik switches. One of the modules was dead when I used it for the first time about 6 months after I purchased it, but customer service at 10Gtek promptly processed a warranty request and I had the new part in a few days. Overall very happy with the purchase.

These do get hot which is expected, it does switch speed as it needs if your connected device does not support the highest speed. Seems to be very compatable with most SFP enabled switches.

The 1G/2.5G/5G/10G-T transceiver I purchased did not correctly negotiate 2.5G with my cable modem on my Unifi Dream Machine Pro. UDM Pros will see SFP jacks as either 1 or 10G, so the negotiation actually is happening inside the module itself. I tried to manually set the connection rate at 1G or 10G in the console, and was not able to get either functional. I would pass on this if you have a Unifi stack!

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.

Works Great
