RJ10

Works well with my Unifi Dream Machine Pro. Moved from 1Gbps to 2.5 Gbps fiber and needed a faster port. Would love to go straight to fiber but Internet provider insists on using their ONT with 10Gbps ethernet port. Runs hot, but have no issues. Rock solid for two weeks now.

These are actual decent and stable transceivers, no connection issues, they don't lie about what they are in the firmware and properly report temperatures, speed, etc. Expensive, but I haven't found others that work as good as these...

If you have a ubiqiuty UGX or dream machine (or switch) this is the SFP to buy - This is plug and play and will work on 2.5, 5, 10Gbps.

On have 2GbE service over Xfinity and this is the ONLY SFP+ RJ45 module to solve my lockup problems with my cable modem on my UDM Pro. The problem is that most SFP+ copper modules initiate auto-negotiation of speed during traffic spikes. That ends up causing the link to freeze with the cable modem. The Microtik manages to hold the 2.5GbE link and keeps it with the modem. Although this is a more expensive SFP+ module, it is the best value for the money considering the fact that it does not run insanely hot like most of these and it doesn't have synchronization issues. It's simple to use by just popping it in and you can forget it from then on. The S+RJ10 is a must on Unifi SFP+ WAN connections because of its functionality in maintaining a connection. This is important because after Unifi Network v10 there is no capability to lock the speed on an SFP+ port any longer.

I purchased this transceiver due to the fact that it provides the best throughput and stability compared to other transceivers on the market. Other adapters seemed to either have issues with upstream speeds, or with flow control issues at speeds between 1Gbps and 10Gbps (2.5Gbps being the most common). I use these with Ubiquiti Dream Machines and Gateways, as well as with Mikrotik CHR on an x86 hypervisor. Now, there are newer transceivers out there which can handle longer cables, and which run cooler. This is still my tried and true transceiver until I find a better one. This Mikrotik transceiver can get hot, so ensure it is given adequite cooling, and avoid placing these next to each other in adjacent slots unless there is space in between to allow for cooling.

I use this SFP+ module on my Ubiquiti UDM Pro WAN port. This module, as opposed to others, can negotiate different speeds on the SFP+ and ethernet sides. This lets you take a 10G only SFP+ port (like on the UDM Pro) and hook it up to a 2.5G Ethernet device, like my Comcast modem. This allows me to take advantage of the overprovisioning (1400 Mbps) on my xfinity service. Note that this works on other devices, too. I have also used it on a Brocade 10G-only SFP+ port with another 2.5G ethernet device. No issues with either application. There might be cheaper alternatives, but Microtik is a well-known name and the module worked well enough for me that I bought a second.

Had purchased an Ipolex SPF 10G and had to return. the download speed was not up to par with a gigabit fiber and the upload speed was erratic and abysmal. The Mikrotik works just fine giving me consistent download and upload speeds on the gigabit wan. It does run very hot and I was concerned that it would fail sooner than later. Heat is the arch enemy of ICs. I created a heatsink using a 4 inch piece of U channel aluminum and used CPU thermal paste to maximize heat transfer. The temperature before HS was running around 70C (158F) with the heatsink its now running about 10C cooler or 60C (140F). only time will tell how well this works.

On the pricey side, and they run ridiculously, hilariously hot (95-105C), but they can reliably push 10GaseT though the existing Cat5e runs in the walls of my multi-story house, where no other SFPs I've tried have been successful. I only bother with these for long in-wall runs - cheaper knock-offs (e.g. Ipolex and 10GTek) work fine for short 3-6 foot patches, e.g. between a switch and a PC, and run much cooler. If you've dismissed 10G as not being possible in your setup due to old wiring, it's worth giving a pair of these a try. Note that if you're not constrained by existing wiring, though, you're almost certainly better off using fiber instead of twisted pair copper - it's generally much cheaper and easier all around when dealing with 5-10 gig networking.

Ich habe vor kurzem das 10GbE Copper Module angeschafft und bin sehr zufrieden mit seiner Leistung. Die Installation war unkompliziert, und die Verbindungsgeschwindigkeit ist beeindruckend. Es ermöglicht mir, große Datenmengen schnell zu übertragen, was meine täglichen Aufgaben erheblich erleichtert. Die Qualität des Moduls ist hervorragend und es scheint sehr robust zu sein. Ich kann es jedem empfehlen, der eine zuverlässige und schnelle Netzwerkverbindung benötigt!

Great

Fast Delivery, good quality

It inadvertently worked as a cable diagnostic tool coupled with the link speed reporting of the switch at the other end. I was horrified to see it negotiated 100 Mbps at the copper end, but that was the idea after reading reviews on here; essentially to determine if the in-wall CAT5e cable was actually 10 Gbps worthy or merely reporting that as the link speed over RJ45. TLDR - The CAT5e cable was actually good as when I swapped the CAT8/40Gbps rated _patch_ cable (that looks like something out of Transformers), from the wall, the link went to 10 Gbps. Just seeing that it can detect a bad cable assures me that the 10 Gbps is probably legit.

Nach dem mein alter 10Gbit Adapter nicht in der Lage war fehlerfrei mit einem 2,5Gbit Netzwerk zu kommunizieren, habe mir nun diesen zugelegt, welcher fehlerfrei Funktioniert. Verwendet in einem QNAP NAS, der einzige Minuspunkt ist der Preis
