What customers say

Have been using FLEXOPTIX transceivers for a few years now in a carrier/telecoms environment for various vendors and they've never disappointed me. After having the opportunity to be able to program them myself on demand, I've realized how many hours I could have saved until now with FLEXBOX! No large stocks, just a few generic SFPs in stock waiting to get programmed when needed. Awesome!
Michael Nicolaou Senior Network Consultant, CDMA Services Ltd

FLEXBOX made my life a lot easier, adapting to multiple hardware in a breeze. I used fiber/SFP, RJ45/SFP, RJ45-10G/SFP for an esports production with different hardware brands and all of them worked instantly.

Before being a FLEXOPTER I had a lot of trouble communicating with my infrastructure and acquisitions team because of the complexity of compatibility between different brands and models

now I can operate and adapt to each on site production.

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

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.
