ipolex SFP+ to RJ45 10Gb Module, Support 1G/2.5G/5G/10GBase-T RJ45 SFP+ Module, Compatible for Cisco SFP-10G-T, Ubiquiti UACC-CM-RJ45-MG, Mikrotik, Netgear, TP-Link, D-Link and More, up to 30 Meters

I have about 75ft to 80ft of CAT6 (including the patch cables) I routed through the wall a few years ago and I'm able to maintain a stable 10g connection with low RETR on iperf3 between these transceivers. They get very hot, too hot to touch for more than 1 sec, but they function well. They do cool down very quickly (few minutes to about room temp) once removed or powered off. I bought about 10 in total and I would buy more if needed.

This unit is Compatible with Synology. Make sure the 10GB SFP+ Card is an intel board, not a CICSO. this transceiver works great

Works great, doesn't appear to get as hot as some of the its competitors.Gives me a stable 5GBit/sec connection (max speed that my PC supports), which is great since while many of the other brands will do 2.5 or 10Gbit, not all support 5Gbit.Works great in combination with the Ugreen 2.5Gbit/10Gbit SPF+ switch (Amazon ASIN B0DY1R3S7N)didn't need to do any confiiguration, just plug it in and go.

I used these as a lower cost alternative to the Unifi product. Easy to install, same size and quality, but a great value. Perfectly compatible with our Unifi switches.

This SFP+ module works exactly as advertized. My particular application is interfacing a 2.5gb ethernet machine to a 10gb ethernet switch. It does get significantly hotter that optical sfp+ modules even at idle, but a quiet 80mm fan blowing across the face of the switch appears to keep temps in control.

Functioned as expected, meet and exceeded all my husband's expections for a desktop 10GB switch.Seamless integration into Unifi ecosystem. In use since May 2025.

First the specifics:I have this transceiver in the WAN port of my UDM PRO (set to Auto Negotiate) and connected to a 2.5Gb modem. The UDM side is seeing this as a 10Gb connection and the transceiver is correctly transforming the connection to 2.5Gb for the modem.Qualities:As with most if not all SFP+ to RJ45 transceivers, this unit gets hot. More importantly, it comes with a 3 year warranty which shows the manufacturer's trust in the product. Another important consideration is power draw as there is a wide disparity between brands. ipolex seems to be in the middle here although I didn't test this for myself.Experience:I can see from a speed test that I am getting nearly the entire 1.2Gb bandwidth promised by my ISP. Due to my configuration, I did not test at faster speeds. I got a little over a year with no problems and then started to have daily connectivity issues. After a few months of that, the transceiver died. It was difficult to figure out how to get warranty service since the manufacturer, like most, requires that I go through the retailer (Amazon) and Amazon doesn't make it easy to find the link. However, once I got to the correct screen and was now dealing directly with ipolex, the process went quickly and they replaced the faulty transceiver. Start to finish, I had the replacement in my hands in 4 days.Quality:One failure is not an indication of quality as I have had failures with every brand. I use that much equipment. Best I can say here is, let's see how long the replacement lasts.

I have been using this item for a period of time at 2.5gig from my ISP and have it connected to the other device (Ubiquiti dream machine pro) at 10gig. This has worked fantastic and was a great price for its performance. I have not needed to give this another thought and would definitely repurchase this if I needed another one instead of a DAC for some reason.
