No complaints on the product, great stuff. The service at FS is what is what stands out though. My rep, Flora, is the best! She is fast and focused to what I need. FS ships the product out fast too!

Thanks for reaching out, all the stuff we got from you all is great so far! We will keep FS in mind when purchasing in the future when new needs arise.

FS.COM has always provided the exact product that was ordered. Quality is always top notch which is hard to find in todays world. Shipping is always lighting fast even if the product is coming from overseas.
Zola is excellent to work with, kind, and always sends friendly reminders and updates.
I personally will continue to work with FS.COM for future needs and recommend everyone to do the same!

This is the first testing order of 100G, we used it on Cisco 9000, which I saw that they have the same type on the web. Before the delivery, I asked my sales Carol to send me the testing results, everything seemed fine. When we received it, all function well. Although one bag for one module successfully protects the module, but it's a little wasteful, next time, if we purchase 10pcs, they said that they will put in one box.

Our data center needed some 100G optics to upgrade the network. I found these FS modules online accidentally and assumed that they were high-performance after checking the detailed info presented in the datasheet. Then I placed my orders. These 100G LR4 optical modules were well-performed indeed and helped to realize a flawless connection in our data center.

Not sure which model is better for me, one is $100 expensive than the other, I called and let them know my application, the customer service recommended the $599 one, and claim that this one is ideal for my telecom field. Very helpful, I've been able to test it out and it works perfectly! You've definitely earned a customer for life.

Alles super gelaufen, vielen Dank. Immer wieder gern.

Emballage niquel. Fonctionne parfaitement en 10Gbps.

Schnelle Lieferung, sorgfältige Verpackung, gute Verarbeitung des Moduls, keine Spuren gebrauchter optischer Ports, schnelle und stabile Übertragungsgeschwindigkeit.

Wir habe diesen 100G Modul in unserem Projekt verwendet und es funktioniert gut. Ich hoffe, weitere Zusammenarbeit zu haben.
