What Customers say

• "Since we ordered a FLEXBOX, our life as definitly changed. There’s a before and an after FLEXBOX. So many vendors in the compatibility matrice, so easy way to configure the module! And the cables and accessories came also with quality."

  Stéphane Gouron

  Directeur Agence Ouest, S-cube.
• "Spending a few minutes of my time, first and foremost expressing how much I’m impressed by your friendliness, is the least I can do. Friendliness was followed by super-fast order processing and delivery. In a few words, unboxing and using your Flexbox is an utterly awesome experience. As in brilliant. Also saving us loads of time ordering optics. In addition to all of this – you deliver particular good build quality, too. You’ve got me impressed, thank you!"

  Mark van den Berg

  CTO - Icera Networks
• "We use “FLEXBOX” and “FLEXOPTIX” for a few years now. Since then life is much easier. And even saved me sometimes in the middle of the night. Need a special vendor or type, plug it in, program, and done. Very… but very occasionally a compatibility is not present in the system. Just drop a e-mail to support with your needs to get an immediate response from “JIRA – the flexoptix robot” and your compatibility is added to your FLEXBOX within 24 hours. Just awesome!!"

  Nick Derksen

  Infrastructure Engineer, Previder B.V
• "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."
