What customers say

Using FLEXBOX and FLEXOPTIX transceivers mean for us Flexibility. We don’t use so much transceivers but we work with different brands each day. With a small amount in stock we can configure them with the right specifications for each use. Assuring it will perfectly fit the requirements of our equipments and costs are also reduced considerably. Setting up either the FLEXBOX and a transceiver on a computer or through the mobile app is just easy as 1,2,3. It tooks us less than 15 minutes between unboxing and using a transceiver. We really appreciate the mobile option so we can have the FLEXBOX in one hand, a transceiver in the other one and the phone with the app in the pocket for programming on the field. Thanks FLEXOPTIX for this really useful tool and for extending supported vendors in the future.
Christophe Mulkers CEO/CTO, Oufti Connections
When in possession of the Flexbox it becomes and indispensable tool in general, and also specifically in managing remote Mobile Base Stations fiber connectivity. Using the Flexbox either with PC or Smartphone is really plug and play with no annoying incompatibility issues at all. The Flexbox together with ease of order and superior delivery times makes it literally unnecessary for us having any significant SFP stock.
Terji Leitisstein Hansen RAN Manager, Vodafone FO

A must-have for every network engineer.
Never again will you have to stock different transceiver types for different vendors for the infrastructure you are using.
The setup of the FLEXBOX is very easy and self-explanatory. The configuration of the FLEXOPTIX universal transceivers is done in seconds and without any problems. Thanks to the smartphone app and the Mobility Pack, even on the go without having to lug around large equipment.

Ten out of ten, absolutely recommended!

Roman Beyerle CODESYS GmbH
