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

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.

Works like a charm, but very hot. Stayed within the documented temperature range/norms when I checked with my thermal camera so I don't expect any issues. The heat makes me nervous for my kids long term however, so I am using this as a short term stopgap.

I ordered the ASF-10G2-T model, and wanted to use it with my Juniper EX switch, so I immediately messaged the 10Gtek support seller (not for Amazon direct sale, must choose 10Gtek) with my Amazon order number and the information that I wanted my SFP+ modules coded to Juniper specs. The seller ( https://www.amazon.com/sp?marketplaceSeller=1&seller=AE2OZG2NN3099 ) immediately responded and confirmed. I received my order directly from China (less than a week), plugged them into SFP0 and SFP2 on my Juniper EX switch. Worked first time, and link-up with my Intel 10Gig interface on my server without any manual configuration.Great Job 10GTek for a great value quality product with customization and customer service.

Does get hot as description says, worked on various lengths and with older cables at 2.5GWindows on ARM driver not working or non-existent, strange as QNAP builds NASs on ARM

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 OPNsenseA.

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.

Works but I eventually replaced it due to needing to reboot the port.

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.......
