What customers say

The FLEXBOX allows us to use 100MBit/s to multi-gigabit transceivers in our product for a wide range of customer needs. We can not solve them without this magic box!
Klaus Degner Managing Director, Allegro Packets GmbH

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.

Stefan Kirbes System Administrator / INTERCOM Austria GmbH

The SFPs easily integrated with our existing network equipment, ensuring cross-vendor compatibility. The build quality is very good.
Connecting to the FLEXBOX with an Android phone took only a few seconds, and configuring the SFPs was a breeze. We really liked the ability to configure multiple SFPs at once. Shipping is incredibly fast. Support is friendly, technical and helpful.

Sebastian Giss System Engineer/cyon.ch
FLEXBOX allows us to reduce the amount of spare transceivers we keep for our diverse hardware systems, thereby keeping overall cost low.
