10G Fiber Media Coverter, 2 Port 10 Gigabit Binardat Ethernet Switch, 1 x 10G RJ45 Port, 1 x 10G SFP Port, Mini Metal Case Fanless, Unmanaged Plug and Play

I ordered this to avoid a long 10gbe run from our fiber from the street to the gateway/route PC. The isp fiber box only has 10gbe copper, and I really didn't want to use a hot power hungry rj45 stp+ module in the gateway/router.So far it works fine in all my tests.

I was able to flash my WAS-110 using this device plugged directly into my PC in addition to using it for Internet access. Flawless running 24/7 for about two months now.Edit: after 4 months the unit began to fail and drop connection constantly. Will look for a different SFP+ switch that isn't this brand next time.

Works for about 30 seconds with a WAS-110 SFP, but then stops working. I don't recommend it.

When I got the first one of these I opened the box and heard a rattling. From the slits in the side I could see that the heatsink appeared to be loose.To their credit, when I reached out to the seller they sent a replacement within a day or two.This new one has a much better connection for the heatsink (from what I can see from the side) and so far it's been working well. I used an RJ45 cable into one side (CAT6 for short length 10g runs) and then a 1310nm SFP on the other side, over to my switch with another 1310nm SFP on that. It immediately detected the network connection, shows 10g lights, and has had no network dropouts for a few days now. Speeds seem very good. It's also not nearly as hot as the original RJ45 SFP I was using - that was too hot to touch for more than a few moments. I also like that this heat is in it's own area, rather than being added to the switch heat load.With this replacement in hand, I opened the original one to see what had happened. I included pictures of what I found. It has four small phillips screws (one beneath a warranty sticker) and then the top plate slides off. In the middle of the circuit board is the network chip. It's got a rubbery thermal pad between it and the heatsink. The heatsink has a glob of adhesive on either side. This apparently had been shoddily done originally - it was angled and not firmly connected (you can see how it originally sat in the pictures), and so fell off in transit. Even had the adhesive not broken, it wouldn't have touched the thermal pad at all, and so wouldn't really have done any good.Be sure you check yours as much as you can before using it. If it's not good you may want to get an adhesive thermal pad or such and swap it out. I was able to chip off the original adhesive quite easily.

I use this to connect my Mac Studio 10G copper port with my fiber switch. I have run a fiber drop through the attic to connect my home office Mac Studio with my server rack that is located in a different room. This help me convert the fiber cable (SFP+) to a copper connection. So far it's been running great. I also tried this converter with a 2.5G port/endpoint and it auto-negotiated successfully. Good device, recommended.

This will auto negotiate from 2.5G up to 10G. Worked as expected. As an IT professional, this converter (and another one on the other end) is what you need to increase your backplane to 10G. Note: It will not support 1G SFP's. That is the description, but I tried anyway just to confirm. I stress tested it for 72 hours and never saw a dip or errors along the way, Make sure your fiber supports the 10G wavelength or speed/distance. The only drawback I saw was that it requires a standard 12v barrel type power adapter. I wish it used 5v on a USB C plug. That would make this perfect. Still giving it 5 stars because the power is a personal preference.

It would be nice if it worked, but it's very unreliable due to the heat it generates. I did make sure the heatsink is in place, as that was an issue reported by other reviewers. Mine was present. It could be reliable with a fan, I think... But it doesn't have one, and doesn't sustain operation for more than an hour or so.

I had purchased a name brand 10G media converter to extend my 1Gb FiOS connection over fiber from the ONT in the garage to my telco rack in the basement, in anticipation of the upcoming 2Gb upgrade from Verizon. Well, that converter worked, sort of. It would get 940-960 Mb upload, but downloads would max out at 10Mb. I swapped that name brand media converter out with this one, same SFP+ and cables, and the upload and download are both at their normal 960~ish Mbps. Glad I had this on hand as a spare, and will continue to use it as long as it works. Will come back and review in 6 months if nothing goes wrong and warrants a review sooner. But so far, very happy!
