Woa, i can get next day delivery for any vendor. That’s a game changer. Also thanks for making it a smartphone app, this fits my workflow well.

Julien BENNET
Technical Director / Areal

First of all, I must salute the both geniously clever and absolutely gorgeous packaging: frankly, my I.T. colleague and I had blinking stars in the eyes when opening the boxes. I had a previous experience with both proprietary and generic transceivers/DAC, and I must admit that your hardware is doing great, everything feels very professional, and thanks to the FLEXBOX, the configuration is super-easy, install the app, insert the transceiver, select model, et voilà! The switches are happy. Thanks for the candy!

Senior Network Consultant / CDMA Services Ltd

Have been using FLEXOPTIX transceivers for a few years now in a carrier/telecoms environment for various vendors and they've never disappointed me. After having the opportunity to be able to program them myself on demand, I've realized how many hours I could have saved until now with FLEXBOX! No large stocks, just a few generic SFPs in stock waiting to get programmed when needed. Awesome!

Sebastian Giss
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.

CEO/CTO / Oufti Connections

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.

You guys rock! I have had the opportunity to use the previous version of FLEXBOX with my previous company. I cannot believe the progress you have made just in a year. Battery pack? Mobile reconfiguration? I am truly feeling lucky to have met you guys at Cloudfest. I will be honoured to demonstrate your products to startups as great examples to contribute to tech sustainability.

When in possession of the FLEXBOX it becomes and indispensable tool in general, and also specifically in managing remote Mobile Base Stations fiber connectivity.Using the FLEXBOX either with PC or Smartphone is really plug and play with no annoying incompatibility issues at all.The FLEXBOX together with ease of order and superior delivery times makes it literally unnecessary for us having any significant SFP stock.

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.
