What customers say

When in possession of the Flexbox it becomes and indispensable tool in general, and also specifically in managing remote Mobile Base Stations fiber connectivity. Using the Flexbox either with PC or Smartphone is really plug and play with no annoying incompatibility issues at all. The Flexbox together with ease of order and superior delivery times makes it literally unnecessary for us having any significant SFP stock.
Terji Leitisstein Hansen RAN Manager, Vodafone FO
It's just a genius device. So easy to use and simple! I would recommend it to every network engineer. Plug-in the module, program and its ready for deployment!

Formerly a System & Network Engineer at the service of French Academic and Research Network and currently developing my own IT services business, I have been a strong advocate of FLEXOPTIX "one-SFP-fits-all" approach since 2015! Having purchased close to 1500 optics over the last few years for different kinds of projects (Metropolitan & Campus Networks, Datacenter, Nexans FTTO projects), I have always been completely satisfied with FLEXOPTIX products. I have had the opportunity to test several competing solutions and for me "FLEXBOX" is by far the most advanced in terms of functionality, ease of use and compatibility. Beyond the flawless technical aspects, the many human qualities of the different people I have had the opportunity to exchange with are a priceless advantage: sympathy, reactivity, impressive know-how, infallible logistics and after-sales services, FLEXOPTIX is a company you enjoy working with and you can trust one hundred percent. Thanks a lot guys!

With the FLEXBOX we’re able to use our Transceivers universally in all kind of equipment and reduce the stock keeping significantly. Just awesome!
