10GBase-SR SFP+ Transceiver, SFP Multi-Mode Fiber LC Module, 10G 850nm MMF up to 300 Meters, Compatible with Cisco, Ubiquiti, Mikrotik, D-Link, Netgear, Qnap, Linksys and More

I recently replaced a smaller QNAP switch with a larger Linksys rack switch. The QNAP had built-in 10GbE ports, and I was really happy with the speeds, but when I tried a variety of 10GbE SFP modules with the Linksys switch—even a brand specifically recommended by Linksys—I just was not getting the same speeds and was experiencing random sluggishness. That said, I decided to try fiber instead, so I ordered these to run some tests, and after a week, I decided to make the change permanently. So far, so good and they seem to run much cooler. My primary switch is about 10 meters from the secondary and I've seen no issues—these are rated for much further, so that's not unexpected—and the speeds are back to what I experienced with my QNAP switch, so I'm a happy camper. I'll update this review in a few months if anything changes, but so far, I would recommend them if anyone needs a 10G fiber SFP transceiver.

I'm new to this, but these seemed to work well.

I tested this SFP+ module with a few others I recently got, and all of them worked without issues. I'm in the middle of upgrading my home and homelab test network to reduce latency and improve speeds, and fiber optics are part of this upgrade project. So far I've been quite happy with how easy the installation process was with these modules. I haven't had to worry about drivers for either Windows or Linux, and the connections were reliable and fast. This specific module is being installed as one of the connections in a Ceph storage network for my Proxmox clusters. Absolutely blazing fast speeds, compared to my previous 1gb rj45 copper network. VM migrations between pve nodes are incredibly quick. This ceph backbone has been working flawlessly for a couple weeks now, and I'm very happy with how it turned out. Highly recommended.

UPDATE Well, it ran for awhile. The performance was good. Recently, however, it has died. The performance became erratic. The module reported good, but the link would go down. I could remove the module for awhile and return it to the slot and it would work for around 10 minutes then fail again. It was very hot. It was not as hot as some UTP modules I've tried, but it was close. I tried a different brand module in the same device which has now been working fine. This product is no longer working for me. --------- I've tested this transceiver together with a different brand connected by standard MMF over 10 meters. The transceiver was instantly and correctly detected in both a Sodola and Mokerlink switch. The full 10G is auto detected without any issue. Transmission is good with no errors or issues at the other end. The transceiver itself does not get hot. Good performance, no heat.

I got a pair of 2.5 GE switches that have 10GE uplink ports. I was using a DAC, but wanted to try out fiber just because. So when this came up on my Vine, I snapped up the pair of them. They installed easily and worked immediately. What more can you ask for from an SFP+?

If you want the fastest ethernet connection for your home network 10 Gps is the way to go, and fiber is the most reliable. Where ethernet wired is good for about 256 feet, fiber can transmit in miles - not that your network covers miles. But it works well if you have outbuildings you want internet in or you just want a 100% reliable network. Once you have the proper network card and switch, you'll still need these transmitters to insert into the switch/ethernet board. These transmitters are what determine the speed of the connection. Transceivers are available from 1Gps up to 40Gps so be sure you match the transceiver to the switch, board, and speed you have.

I loved the way these are packaged, they are kept safe from electrostatic and shipping damage in a nice little can. They can not be easier to use than just plugin them into SFP+ socket on the hub, connecting the LC fiber and off you go. I set up a ram drive and was able to transfer at about 6.5G, I am sure this was a limitation of my computers and not the link. They work great and are very low cost, this allows a home user to deploy a low cost high speed network at home.

These seem well made and of good quality, but my Cisco 2960S said it was incompatible. The picture shows that 1G->1G is possible, but these won't work on older switches. Unable to test speeds because it wouldn't recognize it. If you have a newer switch, I'm sure these would work well, but on older switches, I'd get a different one.
