What customers say

FLEXBOX makes it easier than ever to manage your optics hardware! From unboxing to a configured module in a minute! Great product.
Otto Lodewijk Director, SuitIT
The FLEXBOX is really a great tool. It allows me to quickly re-configure transceivers. Nice additional feature is the "Power Meter & Source" tool. It allows, without additional hardware, a quick check of optical transceivers, fiber cables, fiber connections etc.
René Oskar Kühne Retired scientist, now acting in the field of IT support, R.O. Kuehne

We use FLEXOPTIX modules for years with different networking hardware. Amazing and very stable products without any issues. Preparing a big network project with several switch vendors it was time to do the next step and order a FLEXBOX. Now we can be much more flexible that before and the provided tools are fast, stable, easy to use and as stable as all other FLEXOPTIX producs. All in all - highest recommendation!

Matthias Götz Managing Director / Blue Taurus GmbH & Co. KG
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.
