H!Fiber.com 10Gb SFP+ RJ45 Module, 10Gbase-T Ethernet SFP+ Copper Transceiver Support 10G/5G/2.5G/1.25G, Compatible with Cisco SFP-10G-T-S,Ubiquiti UF-RJ45-10G, UniFi, TP-Link, Meraki, MikroTik, 30m

When they work, they work well. I only have 4 so statistically insignificant. YMMV.I bought these to terminate a short multi-mode fiber (OM3) between the upstairs and downstairs 10G Networks of my home. In AZ we get thunderstorms, and a nearby lightning strike once fried a switch with the induced current in a vertically oriented 1GbE cable so since then it has been fiber.My fiber has three OM3 segments: 3m from the downstairs switch to the wall, a keystone pass-through, a 15m OM3 fiber (UV protected) up the side of the house, another keystone pass-through, and a 5m OM3 fiber to my upstairs switch. At both ends the launch (TX) power is -9.7dBm, and the receive power at the far end is -10.5dBm, as measured with a optical power meter. I was happy with just 0.8dB loss given the pass-throughs. Actually, delighted.First pair of these 10GBase-SR SPF+ units would not hold a signal. They would work for 3-5 minutes and then drop signal for 45-60 seconds. Much angst and substitution testing of everything. Then I bought a second pair of 10GBase-SR units and lo! It works, very stable and now 24 hours without a single lost packet (ICMP Ping). Substitution testing of the four I now have shows one was faulty - the fault follows that unit as I move it around.They are cheap (oh, so cheap!) so you get what you pay for and what you get works extremely well when it works. Certainly worth using and I will buy them again as I build-out my fiber to replace worryingly hot 10GBase-T across my home. (I know - unnecessary really, but I do move very large ISOs and video files every day between 10GB capable machines and those seconds do wear on me).Recommended.

excellent product, rock solid reliable, plug and play operation, works at 2.5Gb

We recently got quantum fiber internet in my area offering 3 gig internet, I wanted a cheap solution to get 3 gig to all my in home appliances as I have a 2.5 gig network anyways. I found this SFP, bought it, came next day, it worked immediately. The speed, the performance and ease of installation was shocking to me. The SFP is definitely a quality SFP module that is a under valued.

It's only been about 2 days, but this SFP module worked perfectly in port 10 of a Unifi UDM Pro. It is working in conjunction with a S33 Arris modem. The UDM Pro reports the module as a 10 Gb module, but auto negotiates down to 2.5Gbs, which is the top speed of one of the wired ports of the S33. Everything is working as designed.

I upgraded from a wireless bridge to fiber optic cable for about a 550-ft run on my farm. What a difference! Much faster and more reliable. These devices worked great to convert the fiber signal to a ethernet connection

I got the dongle to work with my Ubiquiti Dream Machine Pro. When I first plugged it in the UDMP didn't recognize the device. After restarting the UDMP twice, it was able to connect at 1gig. I had to manually switch the port to 10g. I have it connected to my Arris S33 cable modems 2.5 gig port. Now I can get more than 1 gig connection to the UDMP.

This SFP+ to RJ45 module works flawlessly for upgrading to 10GbE over copper, making it a cost-effective alternative to running fiber. The plug-and-play compatibility with Ubiquiti, TP-Link, MikroTik, and other brands ensures easy integration into existing setups. While it does run warm, this is expected for 10GBase-T transceivers, and airflow management helps mitigate any heat concerns. Latency remains low, and I’ve experienced no signal drops or connection issues even over longer cable runs. If you're looking for a reliable 10Gb Ethernet module, this one delivers excellent performance.

Great little module. Easy to install, no trouble with 10gbps speeds. No reason to argue with the price.
