What customers say

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

Sylvain Brisebois Senior Firmware Engineer / KINOVA

We heard about FLEXOPTIX for the quality of its FLEXBOX and optics.
We were able to acquire a FLEXBOX to help out our customers. The quality of the product leaves us speechless. We are immediately going to change optics supplier to FLEXOPTIX. The quality is excellent.

Axel Hauguel CEO / Dyjix

Our engineers spend a lot of time in data centers connecting switches and routers from different vendors. With the FLEXOPTIX service not only their task gets easier, also the back office doesn't have to have a broad range of optics from different vendors in stock anymore.
The days that an engineer stand next to a router with an optic from the wrong vendor are over. With the FLEXOPTIX FLEXBOX the engineer simply reconfigures the optic, and that’s that.
As an added benefit with the FLEXBOX there is no need to connect a new cross-connect to a device to see if it is connected on the other side. The measurement option that comes with the FLEXBOX are very handy!

Thomas Verschuren Technical Consultant / IP Visie Networking 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!
