10Gtek 𝟴𝟬-𝗠𝗲𝘁𝗲𝗿 𝟭𝟬𝗚𝗕𝗮𝘀𝗲-𝗧 𝗦𝗙𝗣+ 𝘁𝗼 𝗥𝗝𝟰𝟱 𝗧𝗿𝗮𝗻𝘀𝗰𝗲𝗶𝘃𝗲𝗿, RJ45 to SFP+ Copper Ethernet CAT.6a Module, for Cisco SFP-10G-T-80, Ubiquiti UniFi, Netgear and More, Pack of 10

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.......

This transceiver worked great in another switch I purchased from Amazon with a no-name Chinese company. I also used it in media converters (fiber to copper) for connecting directly to my computer. It automatically negotiates the speed and was extremely easy to install. It was also compatible in my Intel X710 network card that runs the network for my server to connect to my coax cable modem. The fact this SFP supports multiple speed options is also great because I connected it to a switch with only 10G but it worked fine connected to a 2.5G copper RJ45 jack without any errors, so it must negotiate and rate limit within itself.

The new 80-Meter 10GBase-T (ASF-10G-T80) is definitely the one to get if you don't need 2.5Gb or 5Gb. Working great in my UniFi Dream Machine Pro. A lot lower power consumption than other models means cooler running. Feels warm but not burning hot like I have heard others report with other 10GBase-T SFPs.

SFP+ to RJ45 copper transceivers run hot to the touch because they draw significantly more power than fiber optic modules, often over 3W, to process high-speed 10G Ethernet signals. The small metal case of the transceiver traps heat without an easy way to dissipate it, so these modules can reach temperatures up to 70°C (158°F) and feel very hot during normal operation. Fiber or DAC modules run much cooler by comparison. My 10G Setup: I. Dell Optiplex 7060 SFF i7 8700 (256GB NVMe M.2) running OPNsense A.

This unit worked well for several months and then mysteriously failed. I contacted the manufacturer, and they replaced the device under warranty, and asked me to send them the failed device for analysis (I take that to be a good sign). The replacement has been in use for about 6 months now and seems fine. I'm happy with the service I've received so far. One star removed for the inconvenience of having part of my network go down due to the device failure.

Works like a charm with my UDM Pro

Device couldn't auto negotiate to 1.25 Gbps link speed. When I tried to force the link to that speed, it wouldn't work at all. No matter what I tried, the device just stayed stuck at 10 Gbps and wouldn't auto-negotiate to proper speeds when paired to any interface at varying link speeds. This caused issues when trying to communicate with my ISP via a WAN link. There is quite a bit of overhead as well, expect to lose about 200+ Mbps on your link, even when it does work. Runs hot. Quality is average. I feel like the compatibility isn't great. It was easy to setup. It has a single port capacity. All in all, I feel like this wasn't worth the price I paid.

This was plug and play with my Mikrotik CRS310. I didn't need to change any settings, it instantly detected and linked with my google fiber router at 10g and runs warm to the touch (but not hot). This is the one to get.

Was hunting for a 10G-T SFP and found a lot of people complaining that they run hot… stumbled across some posts that this SFP runs significantly cooler then others and I took a punt… installed in a Mikrotik switch, looked at the health of the SFP and was happily surprised that the temperature reported as 51c while xfering data at 10G speed. Highly recommended and I’m now looking to buy a few more to put in a CRS309.
