What customers say

Great. FLEXBOX does what it says on the tin! - just connect, configure Transceiver and be happy.

James Rice Jump Networks Ltd

Working with the FLEXOPTIX Transceivers and FLEXBOX is not only uncomplicated but offers us the possibility of working with many vendor types to support the different campus networks. Thanks guys - awesome work.

Brian Masiga Network Engineer / Research and Education Network for Uganda

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.

Stuart Willson Infrastructure Engineer / Surrey Satellite Technology Limited

FLEXBOX made my life a lot easier, adapting to multiple hardware in a breeze. I used fiber/SFP, RJ45/SFP, RJ45-10G/SFP for an esports production with different hardware brands and all of them worked instantly.

Before being a FLEXOPTER I had a lot of trouble communicating with my infrastructure and acquisitions team because of the complexity of compatibility between different brands and models

now I can operate and adapt to each on site production.
