What customers say

Very easy to use and quick too. I particularly like the ability to use the same configuration on a number of transceivers just by ticking a box - a real time saver
Mike Dallaway Mira 2014 Limited
Formerly a System & Network Engineer at the service of French Academic and Research Network and currently developing my own IT services business, I have been a strong advocate of FLEXOPTIX "one-SFP-fits-all" approach since 2015! Having purchased close to 1500 optics over the last few years for different kinds of projects (Metropolitan & Campus Networks, Datacenter, Nexans FTTO projects), I have always been completely satisfied with FLEXOPTIX products. I have had the opportunity to test several competing solutions and for me "FLEXBOX" is by far the most advanced in terms of functionality, ease of use and compatibility. Beyond the flawless technical aspects, the many human qualities of the different people I have had the opportunity to exchange with are a priceless advantage: sympathy, reactivity, impressive know-how, infallible logistics and after-sales services, FLEXOPTIX is a company you enjoy working with and you can trust one hundred percent. Thanks a lot guys!

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!
Erwin ter Hofstede CEO, EC-Hosting

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.
