What customers say

Ordering and using FLEXOPTIX transceivers was far quicker than even getting a quote from traditional vendors. 
Using the FLEXBOX is super easy and fast - 5 minutes to get transceivers ready including unboxing and enjoying packaged marshmallows.

Bronislav Robenek Network Architect / Cloud4com

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

FLEXBOX made my life a lot easier, adapting to multiple hardware in a breeze. I used fiber/SFP, RJ45/SFP, RJ45-10G/SFP for an esports production with different hardware brands and all of them worked instantly.

Before being a FLEXOPTER I had a lot of trouble communicating with my infrastructure and acquisitions team because of the complexity of compatibility between different brands and models

now I can operate and adapt to each on site production.
