What customers say
First of all, I must salute the both geniously clever and absolutely gorgeous packaging: frankly, my I.T. colleague and I had blinking stars in the eyes when opening the boxes. I had a previous experience with both proprietary and generic transceivers/DAC, and I must admit that your hardware is doing great, everything feels very professional, and thanks to the FLEXBOX, the configuration is super-easy, install the app, insert the transceiver, select model, et voilà! The switches are happy. Thanks for the candy!
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.
Extensive list of supported vendors.
Your product is like a Swiss Army Knife that all Engineers should have!!
Great Job and keep it up!
FLEXOPTIX creates overall great and reliable products. We need optics for multiple vendors and with the FLEXBOX we are able to simplify our spare part handling.
The best part of the FLEXBOX are the Linux drivers and therefore no need for any additional OS just for branding optics.
