H!Fiber.com 10 Pack 1Gb Multi Mode SFP LC Module, 1000Base-SX SFP Fiber Transceiver, for Cisco GLC-SX-MMD, Ubiquiti UniFi UF-MM-1G, Mikrotik, Fortinet, D-Link, Netgear, Intel, (MMF,850nm,550m,DDM)

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.

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.

Works as advertised, gave me a full 10 Gb when needed.

it did what it was supposed to. it does get really hot, 1 of the 2 came broken but it was replaced easily i was able to get. the speeds i wanted out of it 10Gb on 1 and 5 on the other. connectivity seem stable while i was monitoring it

Worked like a charme

Worked great at 1G and 10G, will not run at 2.5G on my Ubiquiti Dream Router 7

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.

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

Los conecte a equipos TPLink y funcionan bien

Funktioniert wie es soll, keine Einschränkung festgestellt. Tolle alternative wenn alle POE-Ports belegt sind und der Glasanschluss frei ist.

Instalé este SFP+ en un Switch Davuaz y quema al tocar el dispositivo, no se si sea un comportamiento normal o que será pero no me da confianza un dispositivo que se caliente tanto, en cuanto a la velocidad de transmisión llega bien a los 2.5Gb, no he hecho pruebas con otras velocidades.

no fonctionne déjà plus...d'ailleurs c'est pas un 10g mais un 2.5g donc double déception.

Used this transceiver to connect at 2.5G on a USW-PRO-24 switch with the latest firmware as of Jan'24 and worked without any hassles.
