What customers say

FLEXBOX allows us to reduce the amount of spare transceivers we keep for our diverse hardware systems, thereby keeping overall cost low.
Sven Gebhardt Head of Platforms & Services, grandcentrix GmbH
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.
Using FLEXBOX and FLEXOPTIX transceivers mean for us Flexibility. We don’t use so much transceivers but we work with different brands each day. With a small amount in stock we can configure them with the right specifications for each use. Assuring it will perfectly fit the requirements of our equipments and costs are also reduced considerably. Setting up either the FLEXBOX and a transceiver on a computer or through the mobile app is just easy as 1,2,3. It tooks us less than 15 minutes between unboxing and using a transceiver. We really appreciate the mobile option so we can have the FLEXBOX in one hand, a transceiver in the other one and the phone with the app in the pocket for programming on the field. Thanks FLEXOPTIX for this really useful tool and for extending supported vendors in the future.
Christophe Mulkers CEO/CTO, Oufti Connections
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!!
