What customers say

I have my own company, and I work as a network consultant for different customers, especially in the wind turbine business. I am often on turbine sites in the middle of the ocean, where I need a SFP of a certain type/vendor. By using the FLEXOPTIX FLEXBOX, I have solved a very big issue, just by having this tool and some FLEXOPTIX SFP`s in my bag. Then I can solve the issue, and get the site up and running immediately. This saves another trip to site (often by helicopter), and a lot of money and time. I am very exited about this product, and will certainly recommend this product to everybody.

Poul Pedersen Network consultant / Ipwork consult ApS

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
Definitely, FLEXOPTIX will be my optics supplier from today. The ability to compatibilize optics across multiple vendors is going to save us from many headaches. The FLEXBOX is a must for any company using optical network equipment.
Miguel Bérniz Chief Technical Officer, GibFibre Ltd

We heard about FLEXOPTIX for the quality of its FLEXBOX and optics.
We were able to acquire a FLEXBOX to help out our customers. The quality of the product leaves us speechless. We are immediately going to change optics supplier to FLEXOPTIX. The quality is excellent.
