What customers say

Using FLEXBOX we have been able to deliver high quality optical adapter product range in a mixed brand environment, with the maximum flexibility in managing logistic and stock costs. It is a definitely a tool that every professional should use.

Laert Klemo CTO / Eagle Security System

First of all, I must salute the both geniously clever and absolutely gorgeous packaging: frankly, my I.T. colleague and I had blinking stars in the eyes when opening the boxes. I had a previous experience with both proprietary and generic transceivers/DAC, and I must admit that your hardware is doing great, everything feels very professional, and thanks to the FLEXBOX, the configuration is super-easy, install the app, insert the transceiver, select model, et voilà! The switches are happy. Thanks for the candy!

Julien BENNET Technical Director / Areal

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

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