What customers say

On more than one occasion the flexbox significantly saved time for me by not having to scrub a deployment session but simply reconfigure a transceiver and carry on. This alone is a good reason that secures the flexbox a non-negotiable place in my datacenter-go-bag. However what really sets flexoptix apart is not them solving an irritating problem we all know. No. It is their vast inventory and know-how paired with impeccable QA. If I have a need for transceivers it is my single go-to source for procurement. They have exactly what I need in stock even before I know I need it, and when I need it, I can trust the order is in my hands in no time. Every single time. I can configure and deploy without doubt and without delay. It is rare to find such a valuable and dependable partner that reliably takes away a whole set of problems while offering decent pricing and a customer support that is above reproach.

The FLEXBOX is the best thing since sliced bread!
Stefan Ideler CTO, i3D.net

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

I personally did not know FLEXOPTIX yet, but since I got in contact with it the first time, I do not want to miss it anymore. Very good product. I like the ability to program them to vendor specific SFPs which are recognized as they would be original ones. If the hardware behind changes I can simply change the SFPs to new vendor specific ones.

Thank you for such a great product.
