What customers say

Extensive list of supported vendors.
Your product is like a Swiss Army Knife that all Engineers should have!!
Great Job and keep it up!

Fahad Dalwai Network Engineer / Abdulaziz Abdulmohsin Al-Rashed Sons Co. W.L.L.

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

The SFP are exactly like promise on the web page, and the configuration tool is so amazing. I worked years with SFP and optical fiber and this tool is so great. It include a power meter an OTDR and allow to diagnose and configure the SFP for many vendors. It will help us in our research and also to manage our LAN. Thank you FLEXOPTIX

Sylvain Brisebois Senior Firmware Engineer / KINOVA
