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.

Now that I’m done configuring my equipment, I use FLEXBOX to impress associates.
I’m an IT Hero just for the savings, not to mention the FLEXibility to stock one type for each adapter.
Keep up the good work!

Nikos Papandreou IT Admin / Geitonas School SA

Absolutely Flawless! Ultrafast delivery and real plug & play from start to finish. Now we're able to react on needs much quicker thanks to the FLEXBOX.
Having Universal Transceiver on stock and instantly program them to customer's need is amazing.

Elmar Gruber H82 medientechnik GmbH

Working with a lot of different vendor and devices, it is always a problem to find the compatible transceiver from different distributors and especially to ensure that it is really compatible. I have found FLEXOPTIX, and the FLEXBOX and I must say that this is awesome! We can now simply buy generic transceivers and program them with the FLEXBOX and the FLEXOPTIX App. The application is fantastic and very easy to use! This makes us save a lot of time and no more concern about the compatibility.
