Deployed 6 of these optics on my cisco switches without problems. Used FS LC SMF to link everything up. Great experience overall when dealing with FS.

I searched the company's website looking for a kind of SFP+ transceiver for my Juniper switches and finally ordered the XFP-10GZRC-55 module. I find it was exactly what I want to buy that worked fine with my switches. It does just as good as products of other famous brands I have used before.

Love FS.COM. I find myself coming here to shop more and more. Great prices, fast shipping, and great selection of products. Even sometimes, I can't find the one that I need, you will offer you the custom services.

They have a very smart website. the Cisco XFP works, keep it up !

Excellent and informative website. An upper high quality XFP modules, more good with my Cisco 10G switch.

Great as expected.
