FLEXBOX makes it easier than ever to manage your optics hardware! From unboxing to a configured module in a minute! Great product.

System Engineer / cyon GmbH

The SFPs easily integrated with our existing network equipment, ensuring cross-vendor compatibility. The build quality is very good.Connecting to the FLEXBOX with an Android phone took only a few seconds, and configuring the SFPs was a breeze. We really liked the ability to configure multiple SFPs at once. Shipping is incredibly fast. Support is friendly, technical and helpful.

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.

Thomas Verschuren
Technical Consultant / IP Visie Networking B.V.

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!

We are realy happy with the FLEXBOX, programming FLEXOPTIX universal transceivers works like a charm.Just insert, detect, select and start programming, now we are able to support hundreds off vendors with just a few standard SFP modules.Amazing smart solution!

Stefan Kirbes
System Administrator / INTERCOM Austria GmbH

I personally did not know FLEXOPTIX yet, but since I got in contact with it the first time, I do not want to miss it anymore. Very good product. I like the ability to program them to vendor specific SFPs which are recognized as they would be original ones. If the hardware behind changes I can simply change the SFPs to new vendor specific ones.
Thank you for such a great product.

Felix Steiner
Head of Development / F&S Prozessautomation

We are using FLEXOPTIX industrial grade transceivers in our control systems for power electronics and converters. The FLEXBOX is an invaluable tool, making it super easy and quick to configure transceivers. Even larger numbers can be configured easily with the batch configure option, just plug them in one after the other and the rest happens automatically. The power meter, source control and OTDR features are helpful for lab testing or during commissioning. Thanks, FLEXOPTIX for providing universal transceivers of a high quality at decent prices! Your lightning-fast order processing and shipping speed is also impressive.

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.

Abram Lawendy
System Engineer / Zellerfeld R&D GmbH

Thanks to FLEXBOX, you don't need to use hacky hardware configuration that involve allowing unsupported transceivers and hoping they'll work.
The device itself is of high quality. The software has an intuitive design and a user-friendly interface that makes it very easy to use.Configuring the transceiver is a quick and straightforward process, with comprehensive documentation covering most compatibility.
It is truly "The Swiss Army Knife for Network Engineers".
Great job FLEXOPTIX!
