What customers say

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

Christian Seitz Head of Network / STRATO AG

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!

Nikos Papandreou IT Admin / Geitonas School SA

The FLEXBOX was easy to set up and use, and the programmable transceivers worked seamlessly in several different brand devices. This will make our spares much easier to manage.

Shaun James Engineering Inspector / Tata Steel Strip Products UK

FLEXOPTIX have saved us from the misery and disappointment of searching in vain through our box of old, single-vendor transceivers when we need to connect up a device, only to find we don’t have a compatible module. Having the FLEXBOX and programmable transceivers in our toolbox means we’ve always got the right transceiver for any device.  The icing on the cake is the mobility pack which allows you to program any transceivers, anywhere, any time, with just a mobile phone and the FLEXBOX .  Absolutely brilliant and couldn't ask for more.
