What customers say

The new FLEXOPTIX 400GBASE-ZR modules are lit. We’ve been running a few of them in production and they just work. Awesome support from FLEXOPTIX. Keep up the good work!

Viktor Ekmark Cloud Infrastructure Engineer / Elastx AB
Before we knew FLEXOPTIX, we always stocked various types of transceivers from different brands. Now, several years later, we have completely switched to FLEXOPTIX's universal transceivers since we can simply brand these ourselves using the FLEXBOX. Along with their broad product range and very fast shipping, they are an awesome company to deal with!
Jeffrey Bosma XS News , Sr. System & Network Engineer
The FLEXBOX is the best thing since sliced bread!
Stefan Ideler CTO, i3D.net
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.
