I wanted to let you know how happy I am with your products!! I’ve successfully set up my new modules, and I’m up and running at the fastest speeds I’ve ever had!

Yes. Everyone was received and tested OK. Thank you. I will keep FS in mind if I need anything more in the future.

Thanks very much for the fast shipping. I got the modules today and already installed. Working nicely

I ordered my goods through your website and one day later they are already delivered. So you delivered the goods from your German warehouse to a Belgian location in one day … and that’s without asking for a faster delivery. That’s amazing these days. You guys know what you’re doing. I'm gonna change de initials of FS into Fast Service.

Nous voulons réaliser une transmission d'environ 8 km, ces modules BiDi performants assurent un fonctionnement assez stable !

Cannot believe how effective they are. Quick to reply emails and helped me remotely set up works as expected even I only bought some few optics. Knowledgeable people and excellent service.

Le module bon marché est bien compatible avec nos commutateurs Cisco 25G. Bien emballé, bien livré, bonne fonction. J'en suis satisfait.
