What customers say

The flexbox has been an amazing tool for our Equinix AM5 deployments, we have used many brands previously however the flexbox was superior right from the start, especially when working in the datacenter and not needing to hold my laptop in my hand but my phone, which is just amazing for rapid deployments.

Looking forward to keep using the flexbox in the future! :)

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!

FLEXOPTIX creates overall great and reliable products. We need optics for multiple vendors and with the FLEXBOX we are able to simplify our spare part handling. The best part of the FLEXBOX are the Linux drivers and therefore no need for any additional OS just for branding optics.
Dominik Grueber Hetzner Online GmbH / Network Administrations

I personally did not know FLEXOPTIX yet, but since I got in contact with it the first time, I do not want to miss it anymore. Very good product. I like the ability to program them to vendor specific SFPs which are recognized as they would be original ones. If the hardware behind changes I can simply change the SFPs to new vendor specific ones.

Thank you for such a great product.
