What customers say

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

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
Very easy to use and quick too. I particularly like the ability to use the same configuration on a number of transceivers just by ticking a box - a real time saver
Mike Dallaway Mira 2014 Limited

I had the chance to flash my first transceiver with the flexbox and also navigate through the different tools on the Windows App. I must say that I’m impressed by the flexibility and available features provided by this app and the Flexbox. I flashed a 1G LX optic to be compatible with a HP switch in production (Aruba Networks(ex. HP Network) / J4858A) and the switch immediately recognized the plug freshly configured. I can know count on my flexbox for the future transceivers I’ll need to install/replace. Also, the optic measurement is a very good feature.
