What customers say

We use “FLEXBOX” and “FLEXOPTIX” for a few years now. Since then life is much easier. And even saved me sometimes in the middle of the night. Need a special vendor or type, plug it in, program, and done.  Very… but very occasionally a compatibility is not present in the system. Just drop a e-mail to support with your needs  to get an immediate response from “JIRA – the FLEXOPTIX robot” and your compatibility is added to your FLEXBOX within 24 hours. Just awesome!!

Nick Derksen Infrastructure Engineer / Previder B.V

We use FLEXOPTIX modules for years with different networking hardware. Amazing and very stable products without any issues. Preparing a big network project with several switch vendors it was time to do the next step and order a FLEXBOX. Now we can be much more flexible that before and the provided tools are fast, stable, easy to use and as stable as all other FLEXOPTIX producs. All in all - highest recommendation!

Matthias Götz Managing Director / Blue Taurus GmbH & Co. KG

I wanted to take a moment to provide some feedback regarding the on-site programming capabilities of your FLEXOPTIX product. I must say that being able to program SFPs on-site according to our specific requirements has been an incredibly valuable feature for our network infrastructure. The convenience and efficiency it offers have exceeded our expectations.

One of the standout benefits we have experienced is the rapid deployment it enables. Being able to respond quickly to changing network needs without having to wait for orders from different vendors has significantly reduced our deployment time. This has improved our operational efficiency and allowed us to be more agile in meeting our organization's evolving demands.

Moreover, the cost savings we have achieved through on-site programming have been remarkable. By eliminating the need to order pre-configured SFPs from various vendors, we have saved on shipping costs, streamlined our inventory management, and bypassed vendor-specific pricing structures. This flexibility has positively impacted our budgeting and overall equipment expenses.

This is simply a brilliant idea and product! Thank you!

FLEXBOX allows us to reduce the amount of spare transceivers we keep for our diverse hardware systems, thereby keeping overall cost low.
