When you unpack it, you immediately notice: A lot of time and love was invested in this great device. In just a few minutes everything is ready to go and the first transceiver can be configured. The app responds quickly and is well laid out, and the search function makes it easy to find the right configuration. The Flexbox is ideal for us because we use switches from many different manufacturers and can thus react flexibly to changes in our infrastructure at any time. Even on site, we can make adjustments at an instant thanks to the support for mobile devices for configuration.

Stefan Lieven Teamleitung EDV / Pflegeheime Esslingen

As a network engineer responsible for programming universal transceivers, I can confidently say that the FLEXBOX is a true game-changer in the field. Its unparalleled capabilities and user-friendly interface makes the process effortless and highly efficient.

One of the standout features of the FLEXBOX is its ability to support a wide range of transceiver types and brands. Whether you're dealing with SFP, SFP+, QSFP, the FLEXBOX has got you covered.

Martin Fiegel Network Engineer/ Soapeople.com

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!
