What customers say

The FLEXBOX allows us to use 100MBit/s to multi-gigabit transceivers in our product for a wide range of customer needs. We can not solve them without this magic box!
Klaus Degner Managing Director, Allegro Packets GmbH

We are realy happy with the FLEXBOX, programming FLEXOPTIX universal transceivers works like a charm.
Just insert, detect, select and start programming, now we are able to support hundreds off vendors with just a few standard SFP modules.
Amazing smart solution!

Stefan van Merriënboer Senior ICT Consultant / Effisol
We will now be able to source all our SFPs from a single vendor without having to worry about the configuration. That translates to peace of mind and huge flexibility. Well done guys!
Gregory Agerba CTO, Neocarrier Communications
Now that I’m done configuring my equipment, I use FLEXBOX to impress associates. I’m an IT Hero just for the savings, not to mention the FLEXibility to stock one type for each adapter. Keep up the good work!
