What Customers say

  • "The FLEXBOX was easy to set up and use, and the programmable transceivers worked seamlessly in several different brand devices. This will make our spares much easier to manage."
    Shaun James
    Engineering Inspector, Tata Steel Strip Products UK
  • "Der Knaller ist die Verbindung zwischen Smartphone und FLEXBOX mit dem beiliegenden Kabel. So liegt die FlexBox bei uns nicht nur im Schrank oder auf dem Schreibtisch, sondern kann 'mal eben' in jedem Rucksack mitgenommen und mobil eingesetzt werden. Gerade für Notfälle wunderbar!"
    Dennis Köster
    Leiter IT-Abteilung, Hochschule für Gestaltung Offenbach am Main
  • "The FLEXBOX is really a great tool. It allows me to quickly re-configure transceivers. Nice additional feature is the "Power Meter & Source" tool. It allows, without additional hardware, a quick check of optical transceivers, fiber cables, fiber connections etc."
    René Oskar Kühne
    Retired scientist, now acting in the field of IT support, R.O. Kuehne
  • "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!"
