What customers say

You guys rock! I have had the opportunity to use the previous version of FLEXBOX with my previous company. I cannot believe the progress you have made just in a year. Battery pack? Mobile reconfiguration? I am truly feeling lucky to have met you guys at Cloudfest. I will be honoured to demonstrate your products to startups as great examples to contribute to tech sustainability.

Murat Aybars Founder / Ideatomy

As an IT company specializing in the installation of network equipment, we've found FLEXBOX by FLEXOPTIX to be an invaluable tool. Its versatility across various transceivers and user-friendly interface has made our job easier and more efficient.

One of the most impressive aspects of FLEXBOX is the reusability of the transceivers. This feature allows us to reconfigure and reuse the transceivers as needed, offering unprecedented flexibility and cost savings.

The performance is robust, and FLEXBOX has not only saved us time but also provided a cost-effective solution without sacrificing quality.

In summary, FLEXBOX by FLEXOPTIX is a must-have tool for anyone in the networking field. We wholeheartedly recommend it and give it a five-star rating.

Gregory Baer CEO / World-Connect Sàrl

We will now be able to source all our SFPs from a single vendor without having to worry about the configuration. That translates to peace of mind and huge flexibility. Well done guys! 

Gregory Agerba CTO / Neocarrier Communications

The SFP are exactly like promise on the web page, and the configuration tool is so amazing. I worked years with SFP and optical fiber and this tool is so great. It include a power meter an OTDR and allow to diagnose and configure the SFP for many vendors. It will help us in our research and also to manage our LAN. Thank you FLEXOPTIX
