They worked when tested , and a good deal for a two pack. I trust this brand.

I bought these and a fiber cable to connect the SFP ports on two switches and they worked perfectly.

Used in a cisco 220 series, Worked right away.

1g cards. Work good

I bought this 2-pack of Cable Matters multi-mode SFP transceivers to connect my home network to my shop network, and they work flawlessly with my Ubiquiti gear. Easy to install and recognized instantly with no compatibility issues. The connection is stable with excellent speed over fiber. If you need dependable SFP modules, these are a great pick!

Had zero issues with these modules, Put them in a PC and a Cisco switch, they linked right up and getting 1GB on my SFP connection.Great price and working awesome!!

This transceiver works flawlessly in a Cisco 3850 switch and a 5508 WLC. So, the odds are pretty good of it working in whatever Cisco gear you've got..

After the confusion in the question section, I just wanted to post my results. I used a 3m OM2 50/125um LC to LC patch cable from BeyondTech. It worked instantly; the network recognized the connection and away I went. I used this to connect a new HPE server with SFP+ ports to a Cisco network switch with SFP port (non-plus). Pay attention that I plugged in this SFP device into an SFP+ port and it operated at the 1gb connection speed. Windows update ran fine on Server 2019 without hiccups or disconnections of any kind.I have not done any long term tests but I doubt I should run into any compatibility problems. I cannot answer how long this device is going to last. All I can say is that it works fine with an OM2 cable @ 50/125um. If there are any issues in the future then I will update this review.
