What Customers say

  • "Echtes Plug&Play für Netzwerker. :) FLEXBOX einstöpseln, Transceiver rein, gewünschte Konfiguration auswählen, fertig! Das ist das Ende unserer Transceiversorgen."
    Michael Turck
  • "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
  • "It's just a genius device. So easy to use and simple! I would recommend it to every network engineer. Plug-in the module, program and its ready for deployment!"
    David Schoefberger
  • "Als Netzwerkdienstleister haben wir in Kundensituationen und in unserem Labor ständig mit anderer Hardware zu tun. Die FlexBox und die zugehörigen Transceiver sind ein Segen für unsere Laborumgebung. Eine Hardwarebasis, die sich auf alle Herstellerumgebungen anpassen lässt. Einfach und genial."
