The generic SFP+ works great with Intel NICs and this was just what we needed for a 45km span. Best of all, the helpful staff at FS got it to me via next day shipping. Fantastic!

Love these modules. I have used them linking our cisco nexus switches. They worked flawlessly, did not seem to get hot or anything like that, I will certainly buy again from here.

As a non expert I called for some advice and was directed to the exact products I needed. Two 5dB attenuators deployed for the 10GBASE-ZR/ZW and OTU2e SFP+ 1550nm 80km DOM transceiver module realizes the 40km transmission. Very much appreciate the advice, quick service. Especially as you must be so busy with everyone failed in selection or utilization. Impressed! I will definitely use FS again.

Not only does FS have a wide range of modules, their prices are excellent. The web site was easy to navigate, the payment section was easy to complete. I will definitely do further business with this company and recommend it to others.

There was an optical distance of approx 38 km on a dark fiber circuit I just got installed. Hesitated to buy 40km transceivers or 80km ones. Asked FS AM for help and she said it would be better to choose the 80km one in case of insertion and link loss. She also kindly reminded me that I should use the UPC LC cables and add one 5db fixed fiber attenuator for this link. I received all of them within three days. Now the transceivers work flawlessly on my cisco switch. Yep, everything was perfect as she said.

I needed some 80km SFP+ transceiver for my cisco nexus switch. Wanted to buy transceivers that could support FCoE. Asked FS AM and she recommended this transceiver to me. Received them and plugged immediately to my cisco nexus, no issues happened. Two months passed, they have been working well without malfunction at all.

Plusieurs achats effectués sur FS, bon conseil en cas de doute sur un produit en les appelant, en cas de problème le SAV est très disponible !

I have ordered from this shop since 2015, over the three years, we have installed many of FS 10 gigatbit SFPs in our network platform. I really like the services and products your guys offered, and especially the price. Didn't notice before that the price ZR dropped to $ 299, I 'd like to order more next time.

I started to buy from FS.COM for a long time. The website always gives me a surprise, no matter on quality or the price. Actually, I used to have a few issues on the compatible problems before, but I can see their efforts. Now the quality is getting better and better but the price does not raise, even lower than before. Will continue to buy from FS.COM in the future.

I did order the HP Copper SFP modules last year and they are working perfectly for my customer. For this year, I ordered Cisco 10GBASE-ZR SFP+ modules, I haven't received the feedback yet, but I believe they will be good, too, a reliable and trustworthy supplier!
