Your vendor / compatibility is missing?

What customers say

FLEXOPTIX creates overall great and reliable products. We need optics for multiple vendors and with the FLEXBOX we are able to simplify our spare part handling. The best part of the FLEXBOX are the Linux drivers and therefore no need for any additional OS just for branding optics.
Dominik Grueber Hetzner Online GmbH / Network Administrations
Your FLEXBOX rocks. On our Linux workstations we can easily change the vendor and thus save costs. In addition, we are also convinced by the product quality, the support and the handling of the order. Thank you!
Martin Verges Managing director, croit GmbH

When you unpack it, you immediately notice: A lot of time and love was invested in this great device. In just a few minutes everything is ready to go and the first transceiver can be configured. The app responds quickly and is well laid out, and the search function makes it easy to find the right configuration. The Flexbox is ideal for us because we use switches from many different manufacturers and can thus react flexibly to changes in our infrastructure at any time. Even on site, we can make adjustments at an instant thanks to the support for mobile devices for configuration.

Stefan Lieven Teamleitung EDV / Pflegeheime Esslingen
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!
