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.

The price was great and the delivery was very fast.

They have always bee very good.

Item showed up on time for the best price I was able to find.

Packages arrived earlier then expected and were exactly what I expected.
