What customers say

For years we struggled with hundreds of transceivers from different vendors but this is finally over! With FLEXBOX we can easily reconfigure our transceivers which in the end saves a lot of time and money.
Marcel Wösle Director Infrastructure Services, Avira Operations 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.
Michael Horn Telecommunications Infrastructure Security Professional
We will now be able to source all our SFPs from a single vendor without having to worry about the configuration. That translates to peace of mind and huge flexibility. Well done guys!
Gregory Agerba CTO, Neocarrier Communications
Your FLEXBOX rocks. On our Linux workstations we can easily change the vendor and thus save costs. In addition, we are also convinced by the product quality, the support and the handling of the order. Thank you!
