What customers say

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!

What a great product! FLEXBOX is an incredible help to our organisation that has a zoo of vendors and manufacturers in our data center. It is super easy to use and we can rapidly get a transceiver ready for any of our hardware. Q: How to improve the experience of setting up transceivers in a multivendor environment? A: FLEXBOX.

Pavel Sagulenko Head of IT Infrastructure / appliedAI Initiative GmbH

We use FLEXOPTIX modules for years with different networking hardware. Amazing and very stable products without any issues. Preparing a big network project with several switch vendors it was time to do the next step and order a FLEXBOX. Now we can be much more flexible that before and the provided tools are fast, stable, easy to use and as stable as all other FLEXOPTIX producs. All in all - highest recommendation!
