What customers say

I have received my orders from them in blistering speed. Happy to the nth degree.

Pat Cluney  Senior Technical Officer / Waterford Institute of Technology

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

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

In our test environment we use the optics over and over in many devices. Programming optics with the FLEXBOX is as easy as 1,2,3!
