100 Meters, 10Gbps SFP+ to RJ45 Modules, 1G/2.5G/5G/10GBase-T Copper RJ45 to SFP+ Transceiver, Compatible for Cisco SFP-10G-T-X, Ubiquiti, Netgear, Mikrotik, Very Low Power Consumption

Works perfectly in my mikrotik CRS310-8G-2S+IN switch. Worked out of the box with RouterOS, had to update SwOS for it to work, but it worked great once I did. Doesn't seem to run hot (though I haven't actually had it running at a sustained 10Gbps). Overall definitely a good buy

This is a good sfp+ transceiver that does not run very hot and reach 10G speed with the Cat5e cable. With 2 transceivers in Mikrotik CRS305, they are warm to the touch on idle. It also shows the temperature of the transceivers. With a little fan on top, it won't heat up during large file transfer. One thing this can improve is to support 1G speed. Other than that, no complaints so far.

Bought this specifically for my Cisco SG350 switch after reading "100% compatible" in the description. Plug and play? More like plug and pray. Switch doesn't recognize the module at all. Checked logs, tried firmware updates, nothing. Save your money and buy the genuine Cisco module.

While annoyingly expensive, these newer 100m Base-T SFP+ modules are a LOT better than the 30m versions that were sold by a ton of brands for years. They run much cooler, not requiring active airflow if you have a couple next to each other, and I’ve had no compatibility issues with asymmetric transfer rates when they link up at 2.5 or 5Gb like some of the older models do. If you need this, they’re worth the price.

I wanted to try this module because some people have given surprisingly positive feedback about its operating temperatures. The SFP+ ports being stuck together in my router, I couldn't risk a module going up to 90°C like most RJ-45 SFP+ do, and make nearby used SFP+ ports crash. Let's say it fulfills its main role, but this is still a very very mixed bag. Pros: - Works properly at 10 Gb/s. - Stays extremely cool (40°C). - Build quality is alright Cons: - At 1 Gb/s, you have to force 1 Gb/s on the router side for it to work. - At 2.5 Gb/s, download is throttled (random results between 200 Mb/s and 1.7 Gb/s) and the module crashes if you use the download slightly more than idle. Upload can be saturated and maxes out. But with the download being impaired this way, the module is still unusable. - At 5 Gb/s, it doesn't last long. If you launch a speed test, it goes up to 3.6 Gb/s and crashes. - The mechanism to remove it from the router works but is somewhat cumbersome. Tested with Intel, Realtek and Marvell 1, 2.5 and 10G NICs. A lot of people certainly buy it in order to use it at 10G, but the other speeds are still advertised in big characters. So, in my opinion, they should work. Customers should be able to trust a product in every use case the manufacturer says it is made for. If you don't have 10G hardware but a laptop or motherboard with a 2.5G port, forget it. I talked to the brand, they looked like they care but they didn't give me a clear probable cause or point me in the right direction either. I decided in the end not to return it because I don't see a case where I'll need it for other speeds, but this is quite a bit of a shame.

I was using a Fibergaga SFP-10G-T-30M 10Gbps SFP+ to RJ45 module and it worked fine. I just did not like how hot it would run. Under little network activity I measured 126 degrees Fahrenheit with a temperature probe on the outside module case and about 2.5 watts of additional power draw to the switch. I decided to try the Wiitek SFP-10G-T-100 SFP+ to RJ45 module and the power draw dropped to 1.38 watts instead of the Fibergaga SFP-10G-T-30M 10Gbps SFP+ to RJ45 module of 2.5 watts. Also, the operating temperature dropped to 108 degrees Fahrenheit. Both modules worked fine in my network, but I am much happier with the reduction in power and heat generation. So far, I would recommend the Wiitek SFP-10G-T-100 SFP+ to RJ45 module for your copper wire runs.

These work in Juniper switches without issue. Tested Cisco 100m in both EX3400 and EX4300. I believe these are using a newer Broadcom chip. Temps are reported back at 39c/103F which is really good for 10gbase-T. For home use you can get away with using these for some pretty respectable distances on cat5e. Only downside is the cost.

Works fine in my Brocade ICX switch (Cisco 100m version)
